- AIMS: We assessed and compared the diagnostic accuracy of two sets of diagnostic criteria for headache secondary to temporomandibular disorders (TMD). METHODS: In 373 headache subjects with TMD, a TMD headache reference standard was defined as: self-reported temple headache, consensus diagnosis of painful TMD and replication of the temple headache using TMD-based provocation tests. Revised diagnostic criteria for Headache attributed to TMD were selected using the RPART (recursive partitioning and regression trees) procedure, and refined in half of the data set. Using the remaining half of the data, the diagnostic accuracy of the revised criteria was compared to that of the International Headache Society's International Classification of Headache Diseases (ICHD)-II criteria A to C for Headache or facial pain attributed to temporomandibular joint (TMJ) disorder. RESULTS: Relative to the TMD headache reference standard, ICHD-II criteria showed sensitivity of 84% and specificity of 33%. The revised criteria for Headache attributed to TMD had sensitivity of 89% with improved specificity of 87% (p < 0.001). These criteria are (1) temple area headache that is changed with jaw movement, function or parafunction and (2) provocation of that headache by temporalis muscle palpation or jaw movement. CONCLUSION: Having significantly better specificity than the ICHD-II criteria A to C, the revised criteria are recommended to diagnose headache secondary to TMD

Tidskriftsartikel (refereegranskat)abstract
- AIMS: The purpose of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) Validation Project was to assess the diagnostic validity of this examination protocol. The aim of this article is to provide an overview of the project's methodology, descriptive statistics, and data for the study participant sample. This article also details the development of reliable methods to establish the reference standards for assessing criterion validity of the Axis I RDC/TMD diagnoses. METHODS: The Axis I reference standards were based on the consensus of two criterion examiners independently performing a comprehensive history, clinical examination, and evaluation of imaging. Intersite reliability was assessed annually for criterion examiners and radiologists. Criterion examination reliability was also assessed within study sites. RESULTS: Study participant demographics were comparable to those of participants in previous studies using the RDC/TMD. Diagnostic agreement of the criterion examiners with each other and with the consensus-based reference standards was excellent with all kappas > or = 0.81, except for osteoarthrosis (moderate agreement, k = 0.53). Intrasite criterion examiner agreement with reference standards was excellent (k > or = 0.95). Intersite reliability of the radiologists for detecting computed tomography-disclosed osteoarthrosis and magnetic resonance imaging-disclosed disc displacement was good to excellent (k = 0.71 and 0.84, respectively). CONCLUSION: The Validation Project study population was appropriate for assessing the reliability and validity of the RDC/TMD Axis I and II. The reference standards used to assess the validity of Axis I TMD were based on reliable and clinically credible methods.

Tidskriftsartikel (refereegranskat)abstract
- Aims: To derive reliable and valid revised Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) Axis I diagnostic algorithms for clinical TMD diagnoses. Methods: The multisite RDC/TMD Validation Project’s dataset (614 TMD community and clinic cases, and 91 controls) was used to derive revised algorithms for Axis I TMD diagnoses. Validity of diagnostic algorithms was assessed relative to reference standards, the latter based on consensus diagnoses rendered by two TMD experts using criterion examination data, including temporomandibular joint imaging. Cutoff points for target validity were sensitivity ≥ 0.70 and specificity ≥ 0.95. Reliability of revised algorithms was assessed in 27 study participants. Results: Revised algorithm sensitivity and specificity exceeded the target levels for myofascial pain (0.82, 0.99, respectively) and myofascial pain with limited opening (0.93, 0.97). Combining diagnoses for any myofascial pain showed sensitivity of 0.91 and specificity of 1.00. For joint pain, target sensitivity and specificity were observed (0.92, 0.96) when arthralgia and osteoarthritis were combined as “any joint pain.” Disc displacement without reduction with limited opening demonstrated target sensitivity and specificity (0.80, 0.97). For the other disc displacement diagnoses, osteoarthritis and osteoarthrosis, sensitivity was below target (0.35 to 0.53), and specificity ranged from 0.80 to meeting target. Kappa for revised algorithm diagnostic reliability was ≥ 0.63. Conclusion: Revised RDC/TMD Axis I TMD diagnostic algorithms are recommended for myofascial pain and joint pain as reliable and valid. However, revised clinical criteria alone, without recourse to imaging, are inadequate for valid diagnosis of two of the three disc displacements as well as osteoarthritis and osteoarthrosis.

TMD Pain, Physical, and Emotional Functioning Related to Headache Frequency
- 2009
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Temporormandibular disorders (TMD) and tension-type headaches (TTHA) share many signs and symptom and several studies have demonstrated an overlap between these conditions. Objectives: This study investigated the relationship of headache frequency with patient-reported TMD pain intensity, physical functioning, and emotional functioning in subjects with TTHA attributed to TMD. Methods: The RDC/TMD Validation Project, as a subset of 633 TMD cases, identified 153 subjects with concurrent TMD pain diagnoses (RDC/TMD myofascial pain or TMJ arthralgia) and TTHA (International Classification of Headache Disorders-II / ICHD-II) presenting in the temporal region. These subjects also demonstrated pain similar to their headache on provocation by palpation of the temporalis muscle. The headache diagnoses were sub-divided into infrequent episodic, frequent episodic, and chronic TTHA according to the ICHD-II. Outcomes of the study were self-report measures of jaw pain intensity (average pain intensity), physical functioning (Jaw Function Limitation Scale/JFLS, Ohrbach et al, 2008; Graded Chronic Pain Scale/GCPS, von Korff et al, 1992; Short Form -12/SF-12, Ware et al, 1996) and emotional functioning (depression, somatization, anxiety as measured by the Symptom Checklist-90/SCL-90). Differences in outcomes among the three headache subgroups were investigated using ANOVA. Results: Pain intensity in the temple and jaw regions was significantly associated with increased frequency of headache (p<0.01). Physical functioning as assessed with the JFLS (p<0.05) and the GCPS (p<0.01) were also significantly associated with headache frequency. Emotional functioning as assessed with the SCL-90 in terms of depression, somatization, and anxiety were all associated with frequency of headache (p<0.05). In general, the more frequent a subject's TTHA the more severe the levels of outcome. Conclusion: TMD pain intensity, physical functioning, and emotional functioning were associated with the frequency of TMD-related tension-type headache.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact are the four oral health-related quality of life (OHRQoL) dimensions (4D) or areas in which oral disorders impact pediatric patients. Using their dentists' assessment, the study aimed to evaluate whether pediatric dental patients' oral health concerns fit into the 4D of the Oral Health-Related Quality of Life (OHRQoL) construct.METHODS: Dentists who treat children from 32 countries and all WHO regions were selected from a web-based survey of 1580 international dentists. Dentists were asked if their pediatric patients with current or future oral health concerns fit into the 4D of the Oral Health-Related Quality of Life (OHRQoL) construct. Proportions of all pediatric patients' oral health problems and prevention needs were computed.FINDINGS: Data from 101 dentists treating children only and 523 dentists treating children and adults were included. For 90% of pediatric patients, their current oral health problems fit well in the four OHRQoL dimensions. For 91% of oral health problems they intended to prevent in the future were related to these dimensions as well. Both numbers increased to at least 96% when experts analyzed dentists´ explanations of why some oral health problems would not fit these four categories.CONCLUSIONS: The study revealed the four fundamental components of dental patients, i.e., the four OHRQoL dimensions (Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact) are also applicable for pediatric patients, regardless of whether they have current or future oral health concerns, and should be considered when measuring OHRQoL in the pediatric dental patient population.

- OBJECTIVE: To evaluate the reliability of a questionnaire that assessed the expectations and experiences of adolescent patients about orthodontic treatment. MATERIALS AND METHODS: The study included two groups of patients: 30 consecutive patients (19 girls and 11 boys, mean age 14.6 years, SD 2.3 years) naive to orthodontic treatment, and 30 consecutive adolescent patients (17 girls and 13 boys, mean age 15.1 years, SD 2.0 years) in active orthodontic treatment with fixed appliances in both jaws. A questionnaire comprising 46 items was developed, based upon focus group interviews and previous established questionnaires. The questionnaire covered the following domains: Treatment motivation; treatment expectations; pain and discomfort from teeth, jaws, and face; functional jaw impairment; and questionnaire validity. Internal consistency as well as temporal stability with the test-retest method was investigated. RESULTS: A majority of the questions exhibited acceptable test-retest reliability, and composite scores yielded excellent reliability for all domains. Internal consistency was acceptable and good face validity was found for all domains. CONCLUSION: The questionnaire can be recommended for use in the assessment of expectations and experiences of orthodontic treatment.

- Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact—the dimensions of oral health-related quality of life—capture dental patients’ oral health problems worldwide and regardless of whether the patient currently suffers from oral diseases or intends to prevent them in the future. Using scores for these dimensions, the project Mapping Oral Disease Impact with a Common Metric (MOM) aims to provide four-dimensional oral health impact information across oral diseases and settings. In this article, project authors summarize MOM’s findings and provide recommendations about how to improve standardized oral health impact assessment. Project MOM’s systematic reviews identified four-dimensional impact information for 189 adult and 22 pediatric patient populations that were contained in 170 publications. A typical functional, pain-related, aesthetical, and psychosocial impact (on a 0-8 impact metric based on two items with a response format 0 = never, 1 = hardly ever, 2 = occasionally, 3 = fairly often, 4 = very often) was about 2 to 3 units. Project MOM provides five recommendations to improve standardized oral health impact assessment for all oral diseases in all settings.

Tidskriftsartikel (refereegranskat)abstract
- Background: OHIP's original seven-domain structure does not fit empirical data, but a psychometrically sound and clinically more plausible structure with the four OHRQoL dimensions Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact has emerged. Consequently, use and scoring of available OHIP versions need to be revisited. Aim: We assessed how well the overall construct OHRQoL and its four dimensions were measured with several OHIP versions (20, 19, 14, and 5 items) to derive recommendations which instruments should be used and how to score them. Methods: Data came from the “Dimensions of OHRQoL Project” and used the project's learning sample (5,173 prosthodontic patients and general population subjects with 49-item OHIP data). We computed correlations among OHIP versions’ summary scores. Correlations between OHRQoL dimensions, on one hand, and OHIP versions’ domain scores or OHIP-5′s items, on the other hand, were also computed. OHIP use and scoring recommendations were derived for psychometrically solid but also practical OHRQoL assessment. Results: Summary scores of 5-, 14-, 19- and 49-item versions correlated highly (r = 0.91–0.98), suggesting similar OHRQoL construct measurement across versions. The OHRQoL dimensions Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact were best measured by the OHIP domain scores for Physical Disability, Physical Pain, Psychological Discomfort, and Handicap, respectively. Conclusion: Recommendations were derived which OHIP should be preferably used and how OHIP versions should be scored to capture the overall construct and the dimensions of OHRQoL. Psychometrically solid and practical OHRQoL assessment in all settings across all oral health conditions can be achieved with the 5-item OHIP.

Tidskriftsartikel (refereegranskat)abstract
- Background: The Orofacial Esthetic Scale (OES) is an eight-item instrument to assess how patients perceive their dental and facial esthetics. In this cross-sectional study we investigated dimensionality, reliability, and validity of OES scores in the adult general population in Sweden.Methods: In a random sample of the adult Swedish population (response rate: 39%, N=1159 subjects, 58% female, mean age (standard deviation): 49.2 (17.4) years), dimensionality of OES was investigated using factor analytic methods to determine how many scores are needed to characterize the construct. Reliability of scores was calculated using Cronbachs alpha. Score validity was determined by correlating the OES summary score with a global indicator of orofacial esthetics (OE).Results: Factor analyses provided support that a single score can sufficiently characterize OE. A Cronbachs alpha of 0.93 indicated excellent reliability. A validity coefficient of r=0.89 (95% confidence interval: 0.87-0.90) indicated that OES summary scores correlated highly with a global OE assessment.Conclusions: The OES is a promising instrument to measure the construct OE. Factor analyses supported that this construct can be assessed with one score, offering a feasible and acceptable standardized assessment of OE. The present study extends the OES use to the general population, an important target population for assessment of orofacial esthetics. © 2012 John et al.; licensee BioMed Central Ltd.

- OBJECTIVE: The dimensions of oral health-related quality of life (OHRQoL) Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact are the major areas where patients are impacted by oral diseases and dental interventions. The aim of this study was to evaluate whether dental patients' reasons to visit the dentist fit the 4 OHRQoL dimensions.METHODS: Dentists (N = 1580) from 32 countries participated in a web-based survey. For their patients with current oral health problems, dentists were asked whether these problems were related to teeth, mouth, and jaws' function, pain, appearance, or psychosocial impact or whether they do not fit the aforementioned 4 categories. Dentists were also asked about their patients who intended to prevent future oral health problems. For both patient groups, the proportions of oral health problems falling into the 4 OHRQoL dimensions were calculated.RESULTS: For every 100 dental patients with current oral health problems, 96 had problems related to teeth, mouth, and jaws' function, pain, appearance, or psychosocial impact. For every 100 dental patients who wanted to prevent future oral health problems, 92 wanted to prevent problems related to these 4 OHRQoL dimensions. Both numbers increased to at least 98 of 100 patients when experts analyzed dentists' explanations of why some oral health problems would not fit the four dimension. For the remaining 2 of 100 patients, none of the dentist-provided explanations suggested evidence against the OHRQoL dimensions as the concepts that capture dental patients' suffering.CONCLUSION: Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact capture dental patients' oral health problems worldwide. These 4 OHRQoL dimensions offer a psychometrically sound and practical framework for patient care and research, identifying what is important to dental patients.

Development Of An Orofacial Aesthetic Scale In Prosthodontic Patients
- 2010
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Objectives: Despite the interest and need to assess orofacial aesthetics in prosthodontic patients, few self-report instruments are available to measure this construct and none describes how prosthodontic patients perceive the appearance of patients' face, mouth, teeth, and dentures. We report development of the Orofacial Aesthetic Scale (OAS), in particular its conceptual framework, how questionnaire items were generated, and the scale's measurement model. Methods: After test conceptualization, we solicited aesthetic concerns in 17 prosthodontic patients who were asked to evaluate their photographs. A focus group of 8 dental professionals reduced the initial number of concerns/items and decided on an item response format. Pilot testing in 9 subjects generated the final instrument, the OAS. We performed exploratory factor analysis to investigate OAS dimensionality and item analysis to investigate item difficulty and discrimination in 119 subjects. Results: Prosthodontic patients generated an initial 28 aesthetic concerns. These items were reduced to 8 preliminary representative items that were subsequently confirmed in pilot testing. Item analysis supported these 8 items assessing appearance: Face, Profile, Mouth, Tooth alignment, Tooth shape, Tooth color, Gums, as well as Overall impression measured on an 11-point numeric rating scale (0 ”Very dissatisfied”, 10 ”Very satisfied” with appearance). Exploratory factor analysis found only 1 factor and high positive loadings for all items (.73 to .94) on the first factor, supporting OAS' unidimensionality. Conclusion: The Orofacial Aesthetic Scale, developed especially for prosthodontic patients, is a brief questionnaire that assesses orofacial aesthetic impacts with freely available Swedish and English versions.

- Purpose: Despite the interest and need to assess orofacial esthetics in prosthodontic patients, few self-reporting instruments are available to measure this construct, and none describe how prosthodontic patients perceive the appearance of their face, mouth, teeth, and dentures. The development of the Orofacial Esthetic Scale (DES) is reported in this article, in particular its conceptual framework, how questionnaire items were generated, and the scales measurement model. Materials and Methods: After test conceptualization, the authors solicited esthetic concerns from 17 prosthodontic patients by asking them to evaluate their own photographs. A focus group of 8 dental professionals reduced the initial number of concerns/items and decided on an item response format. Pilot testing in 9 subjects generated the final instrument, the DES. Exploratory factor analysis was performed to investigate DES dimensionality and item analysis to investigate item difficulty and discrimination in 119 subjects. Results: Prosthodontic patients generated an initial 28 esthetic concerns. These items were reduced to 8 preliminary representative items that were subsequently confirmed during pilot testing. Analysis supported 8 items assessing appearance: face, profile, mouth, tooth alignment, tooth shape, tooth color, gums, and overall impression, measured on an 11-point numeric rating scale (0 = very dissatisfied, 10 = very satisfied). Exploratory factor analysis found only 1 factor and high positive loadings for all items (.73 to .94) on the first factor, supporting the unidimensionality of the DES. Conclusions: The OES, developed especially for prosthodontic patients, is a brief questionnaire that assesses orofacial esthetic impacts.

Tidskriftsartikel (refereegranskat)abstract
- We reported the development and psychometric evaluation of a Swedish 14-item and a five-item short form of the Oral Health Impact Profile. The 14-item version was derived from the English-language short form developed by Slade in1997. The five-item version was derived from the German-language short form developed by John etal. in 2006. Validity, reliability and normative values for the two short form summary scores were determined in a random sample of the adult Swedish population (response rate: 46%, N=1366 subjects). Subjects with sufficient OHRQoL information to calculate a summary score (N=1309) were on average 50 center dot 1 +/- 17 center dot 4years old, and 54% were women. Short form summary scores correlated highly with the 49-item OHIP-S (r >= 0 center dot 97 for OHIP-S14, r >= 0 center dot 92 for OHIP-S5) and with self-report of oral health (r >= 0 center dot 41). Reliability, measured with Cronbach's alpha (0 center dot 91 for OHIP-S14, 0 center dot 77 for OHIP-S5), was sufficient. In the general population, 50% of the subjects had >= 2 OHIP-S14 score points and 10% had >= 11 points, respectively. Among subjects with their own teeth only and/or fixed dental prostheses and with partial removable dental prostheses, 50% of the population had >= 2 OHIP-S14 score points, and 10% had >= 11 points. For subjects with complete dentures, the corresponding figures were 3 and 24 points. OHIP-S5 medians for subjects in the three population groups were 1, 1 and 2 points. Swedish 14-item and 5-item short forms of the OHIP have sufficient psychometric properties and provide a detailed overview about impaired OHRQoL in Sweden. The norms will serve as reference values for future studies.

Tidskriftsartikel (refereegranskat)abstract
- This study reports the findings and challenges of the assessment of oro-facial aesthetics in the Swedish general population and the development of normative values for the self-reporting Orofacial Esthetic Scale (OES). In a Swedish national sample of 1406 adult subjects (response rate: 47%), OES decile norms were established. The influence of sociodemographics (gender, age, and education), oral health status and general health status on OES scores was analysed. Mean +/- standard deviation of OES scores was 503 +/- 156 units (0, worst score; 70, best score); less than1% of the subjects had the minimum score of 0, and 11% had the maximum score of 70 OES units. Orofacial Esthetic Scale score differences were (i) substantial (greater than5 OES units) for subjects with excellent/very good versus good to poor oral or general health status; ii) small (2 units), but statistically significant for gender (P=0.01) and two age groups (P=0.02), and (iii) absent for subjects with college versus no college education (P=0.31) or with and without dentures (P=0.90). To estimate normative values for a self-reporting health status, instrument is considered an important step in standardisation, and the developed norms provide a frame of reference in the general population to interpret the Orofacial Esthetic Scale scores.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: This study evaluated the reliability and validity of the Orofacial Esthetic Scale (OES) an instrument assessing self-reported orofacial esthetics in prosthodontic patients. Materials and Methods: The OES has seven items addressing direct esthetic impacts in the orofacial region, as well as an eighth global assessment item. The response format was a 0 to 10 numeric rating scale (very dissatisfied to very satisfied with appearance, respectively). OES summary scores ranged from 0 (worst score) to 70 (best score). Test-retest reliability (n = 27) and internal consistency (n = 119) were assessed. Content validation (asking patients about their satisfaction with the questionnaire content, n = 119) and discriminative validation (comparing OES scores between patients and healthy controls, n = 119) were performed. Convergent validity was assessed by correlating patients own OES scores (n = 29) with ratings from a consensus expert group (n = 4) and with the Oral Health Impact Profile (CHIP) esthetic-item summary score (n = 119). Results: Test-retest reliability was excellent for the OES scores (intraclass correlation coefficient = .96). Internal consistency was satisfactory for esthetically impaired patients (n = 27, Cronbach alpha = .86). Patients rated their satisfaction with the questionnaire content as 7.8 +/- 1.3 units on a 0 to 10 numeric rating scale (0 = very dissatisfied, 10 = very satisfied). OES scores discriminated esthetically impaired patients (31.4 units) from healthy controls (45.9 units, P less than .001). OES scores correlated well with other measures of the same construct (r = .43 for patients own assessment with an assessment by experts using the OES, r = -.72 for a correlation with the OHIPs three esthetic-related items). Conclusions: The OES, developed especially for prosthodontic patients, exhibited good score reliability and validity.

Tidskriftsartikel (refereegranskat)abstract
- The aims of this study were, first, to report normative values for jaw movements in Caucasian children and adolescents (maximum opening, laterotrusion, and protrusion) and, second, to investigate the influence of age, gender, and temporomandibular disorders (TMD) on jaw movement capacity. The population-based study included 1,011 randomly selected German children and adolescents, aged 10-17 yr. Case histories, as well as mandibular movements and the presence of TMD, were assessed according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). The mean +/- standard deviation for maximum opening was 50.6 +/- 6.4 mm, for laterotrusion to the right was 10.2 +/- 2.2 mm, for laterotrusion to the left was 10.6 +/- 2.3 mm, and for protrusion was 8.2 +/- 2.5 mm. Bivariable (t-test) and multivariable (linear regression) analyses showed that normative values for jaw opening capacity were influenced by age and gender. No influence on jaw movement capacity was seen when TMD were present. Based on the distribution of the measurements in the population (lowest decentile), the mandibular mobility of subjects with a maximum opening of < 43 mm and laterotrusive movements < 8 mm or protrusive movements < 5 mm might be considered as being limited. However, these limitations do not necessarily require treatment.

Comparison of clinical signs in patients with episodic and chronic tension-type headache attributed to temporomandibular disorders. Preliminary results
- 2008
-
Konferensbidrag (refereegranskat)abstract
- Aim: This study assessed (1) the sensitivity at trigeminal and non-trigeminal site in TMD patients with episodic (ETTH) and chronic tension type headache (CTTH) compared with healthy controls and (2) the relationship between familiar headache in the temples and provocation tests of the masticatory system in TMD patients with ETTH and CTTH. Materials and Methods: 153 TMD pain subjects and 84 healthy controls were enrolled in the study. Inclusion criterion for the TMD subjects was a RDC/TMD pain diagnosis (group I and III) and ETTH or CTTH diagnosed according to IHS criteria. Assessment variables were mandibular range of motion, masticatory muscle and TMJ tenderness, referred pain, pressure pain threshold (PPT), and provocation tests of the jaw. Results: PPT differed significantly between controls and TMD (ETTH and CTTH) patients at trigeminal and non-trigeminal sites (p < 0.001). Number of painful muscle sites increased significantly with headache frequency (p < 0.001). CTTH patients had significantly more sites with referred pain in the temples than ETTH patients (p < 0.03). Overall, 31% of ETTH and 57% of CTTH patients reported familiar headache in one or more of the provocation tests. Conclusion: TMD patients with ETTH and CTTH had increased sensitivity at trigeminal and non-trigeminal sites and more muscle tenderness compared with controls, which suggests involvement of peripheral and central sensitization. Overall, one-third of ETTH and over half of CTTH patients exhibited a causal temporal relationship with familiar headache in the temples following provocation tests.

- AIMS: To investigate the relationship of headache frequency with patient-reported physical functioning and emotional functioning in temporomandibular disorder (TMD) subjects with concurrent temple headache. METHODS: The Research Diagnostic Criteria for TMD (RDC/TMD) Validation Project identified, as a subset of 614 TMD cases and 91 controls (n = 705), 309 subjects with concurrent TMD pain diagnoses (RDC/TMD) and temple headache. The temple headaches were subdivided into infrequent, frequent, and chronic headache according to the International Classification of Headache Disorders, second edition (ICHD-II). Study variables included self-report measures of physical functioning (Jaw Function Limitation Scale [JFLS], Graded Chronic Pain Scale [GCPS], Short Form-12 [SF-12]) and emotional functioning (depression and anxiety as measured by the Symptom Checklist-90R/SCL-90R). Differences among the three headache subgroups were characterized by increasing headache frequency. The relationship between ordered headache frequency and physical as well as emotional functioning was analyzed using linear regression and trend tests for proportions. RESULTS: Physical functioning, as assessed with the JFLS (P < .001), SF-12 (P < .001), and GCPS (P < .001), was significantly associated with increased headache frequency. Emotional functioning, reflected in depression and anxiety, was also associated with increased frequency of headache (both P < .001). CONCLUSION: Headache frequency was substantially correlated with reduced physical functioning and emotional functioning in subjects with TMD and concurrent temple headaches. A secondary finding was that headache was precipitated by jaw activities more often in subjects with more frequent temple headaches.

- OBJECTIVES: For jaw functional limitations measured by the Jaw Functional Limitation Scale (JFLS), (a) determining prevalence in the Swedish general adult population, (b) investigating the influence of demographic factors and self-reported dental status and (c) deriving normative values. METHODS: A random sample of the general adult population in Sweden was approached (response rate: 46%, N = 1,372). Prevalence was determined for the JFLS summary score and individual items. The influence of age, gender and dental status was investigated with regression analyses and normative values presented. RESULTS: The JFLS median score was 0, and all items had prevalences ≤30%. Age and gender did not influence jaw functional limitations but dental status did. Normative JFLS scores were 1, 9 and 28 for the 7th, 8th and 9th deciles, respectively. In dental status-stratified norms, 9th deciles were 20, 43 and 100, for subjects with natural teeth only, removable and complete dentures, respectively. CONCLUSIONS: The Swedish general adult population had excellent jaw function, but dental status was major determinant. In the absence of information linking JFLS scores to important patient concerns, the score distribution can serve as a reference with the 9th decile as threshold for functional limitation.

- ObjectivesTo (i) determine the prevalences of self-report in a Swedish adult population, of temporomandibular disorders, burning mouth syndrome, dry mouth, and bad breath and (ii) determine oral health-related quality-of-life impairment in subjects reporting these conditions. Subjects and methodsA cross-sectional, randomized sample of the adult Swedish population (response rate: 46%, N=1309 subjects) self-reported their condition from the preceding month to assess prevalences of self-report for the studied conditions together with comorbidity group of subjects who reported more than one condition. The 49-item Oral Health Impact Profile (OHIP) used to assess oral health-related quality of life. ResultsThe most prevalent condition was bad breath (39%), followed by dry mouth (22%), temporomandibular disorders (18%) and burning mouth syndrome (4%). High comorbidity of conditions occurred in 27% of the population. Quality-of-life impairment increased with the number of comorbid conditions. Among individual conditions, burning mouth syndrome and temporomandibular disorders (57% and 40% OHIP points) presented higher impairment than dry mouth and bad breath (32% and 26% OHIP points). ConclusionsOrofacial conditions were common and often coexist. The comorbidity group experienced the highest impact on oral health-related quality of life: the more the comorbid conditions, the greater the negative impact.

- AIMS: The original Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) Axis I diagnostic algorithms have been demonstrated to be reliable. However, the Validation Project determined that the RDC/TMD Axis I validity was below the target sensitivity of ≥ 0.70 and specificity of ≥ 0.95. Consequently, these empirical results supported the development of revised RDC/TMD Axis I diagnostic algorithms that were subsequently demonstrated to be valid for the most common pain-related TMD and for one temporomandibular joint (TMJ) intra-articular disorder. The original RDC/TMD Axis II instruments were shown to be both reliable and valid. Working from these findings and revisions, two international consensus workshops were convened, from which recommendations were obtained for the finalization of new Axis I diagnostic algorithms and new Axis II instruments. METHODS: Through a series of workshops and symposia, a panel of clinical and basic science pain experts modified the revised RDC/TMD Axis I algorithms by using comprehensive searches of published TMD diagnostic literature followed by review and consensus via a formal structured process. The panel's recommendations for further revision of the Axis I diagnostic algorithms were assessed for validity by using the Validation Project's data set, and for reliability by using newly collected data from the ongoing TMJ Impact Project-the follow-up study to the Validation Project. New Axis II instruments were identified through a comprehensive search of the literature providing valid instruments that, relative to the RDC/TMD, are shorter in length, are available in the public domain, and currently are being used in medical settings. RESULTS: The newly recommended Diagnostic Criteria for TMD (DC/TMD) Axis I protocol includes both a valid screener for detecting any pain-related TMD as well as valid diagnostic criteria for differentiating the most common pain-related TMD (sensitivity ≥ 0.86, specificity ≥ 0.98) and for one intra-articular disorder (sensitivity of 0.80 and specificity of 0.97). Diagnostic criteria for other common intra-articular disorders lack adequate validity for clinical diagnoses but can be used for screening purposes. Inter-examiner reliability for the clinical assessment associated with the validated DC/TMD criteria for pain-related TMD is excellent (kappa ≥ 0.85). Finally, a comprehensive classification system that includes both the common and less common TMD is also presented. The Axis II protocol retains selected original RDC/TMD screening instruments augmented with new instruments to assess jaw function as well as behavioral and additional psychosocial factors. The Axis II protocol is divided into screening and comprehensive self report instrument sets. The screening instruments' 41 questions assess pain intensity, pain-related disability, psychological distress, jaw functional limitations, and parafunctional behaviors, and a pain drawing is used to assess locations of pain. The comprehensive instruments, composed of 81 questions, assess in further detail jaw functional limitations and psychological distress as well as additional constructs of anxiety and presence of comorbid pain conditions. CONCLUSION: The recommended evidence-based new DC/TMD protocol is appropriate for use in both clinical and research settings. More comprehensive instruments augment short and simple screening instruments for Axis I and Axis II. These validated instruments allow for identification of patients with a range of simple to complex TMD presentations

- Objectives: To compare the frequency of patients' oral health problems and prevention needs among Slovenian and international dentists with the aim to validate the four oral health-related quality of life (OHRQoL) dimensions across six clinical dental fields in all World Health Organization (WHO) regions. Methods: An anonymous electronic survey in the English language was designed using Qualtrics software. A probability sampling for Slovenia and a convenience sampling strategy for dentist recruitment was applied for 31 countries. Dentists engaged in six dental fields were asked to categorize their patients' oral health problems and prevention needs into the four OHRQoL dimensions (Oral Function, Orofacial Pain, Orofacial Appearance, and Psychosocial Impact). Proportions of patients' problems and prevention needs were calculated together with the significance of Slovenian and international dentists' differences based on dental fields and WHO regions. Results: Dentists (n=1,580) from 32 countries completed the survey. There were 223 Slovenian dentists (females: 68%) with a mean age (SD) of 41 (10.6) years and 1,358 international dentists (females: 51%) with a mean age (SD) of 38 (10.4). Pain-related problems and prevention needs were the most prevalent among all six dental fields reported by dentists; Slovenian (37%) and 31 countries (45%). According to Cohen, differences between Slovenia, the broader European Region, and 31 countries were considered non-significant (<0.1). Conclusion: According to the dentists' responses, the frequency of patients' oral health problems and prevention needs are proportionate between Slovenia and 31 countries, regionally and globally. The four OHRQoL dimensions can be considered universal across all dental fields.
