- In the long history of temporomandibular disorders (TMD), the term ”rehabilitation“ has been often associated with ”occlusal rehabilitation“ indicating a specific philosophy in which occlusion is the crucial factor for TMD and that intervention on the occlusion could ”cure“ the problem. In this paper, the term rehabilitation is used to denote any medical, physical, or psychological treatment which brings or restores an individual to a normal or optimal state of health, and this revised concept therefore significantly broadens the scope of rehabilitation of TMD. The purpose of the JOR-CORE in Siena, 2009 was to critically examine the current state-of-the-science in the field of TMDs. This lead to four extensive reviews and the present summaries and recommendations for future research into rehabilitation of TMDs.

- The aim of this meta-analysis was to investigate whether there are any positive effects of prophylactic antibiotic regimen on implant failure rates and post-operative infection when performing dental implant treatment in healthy individuals. An electronic search without time or language restrictions was undertaken in March 2014. Eligibility criteria included clinical human studies, either randomised or not. The search strategy resulted in 14 publications. The I(2) statistic was used to express the percentage of the total variation across studies due to heterogeneity. The inverse variance method was used with a fixed- or random-effects model, depending on the heterogeneity. The estimates of relative effect were expressed in risk ratio (RR) with 95% confidence interval. Six studies were judged to be at high risk of bias, whereas one study was considered at moderate risk, and six studies were considered at low risk of bias. The test for overall effect showed that the difference between the procedures (use versus non-use of antibiotics) significantly affected the implant failure rates (P = 0·0002), with a RR of 0·55 (95% CI 0·41-0·75). The number needed to treat (NNT) to prevent one patient having an implant failure was 50 (95% CI 33-100). There were no apparent significant effects of prophylactic antibiotics on the occurrence of post-operative infections in healthy patients receiving implants (P = 0·520). A sensitivity analysis did not reveal difference when studies judged as having high risk of bias were not considered. The results have to be interpreted with caution due to the presence of several confounding factors in the included studies.

Reasons for failures of oral implants
- 2014
-
Ingår i: Journal of Oral Rehabilitation. - : John Wiley & Sons. - 1365-2842 .- 0305-182X. ; 41:6, s. 443-476

Tidskriftsartikel (refereegranskat)abstract
- This study reviews the literature regarding the factors contributing to failures of dental implants. An electronic search was undertaken including papers from 2004 onwards. The titles and abstracts from these results were read to identify studies within the selection criteria. All reference lists of the selected studies were then hand-searched, this time without time restrictions. A narrative review discussed some findings from the first two parts where separate data from non-comparative studies may have indicated conclusions different from those possible to draw in the systematic analysis. It may be suggested that the following situations are correlated to increase the implant failure rate: a low insertion torque of implants that are planned to be immediately or early loaded, inexperienced surgeons inserting the implants, implant insertion in the maxilla, implant insertion in the posterior region of the jaws, implants in heavy smokers, implant insertion in bone qualities type III and IV, implant insertion in places with small bone volumes, use of shorter length implants, greater number of implants placed per patient, lack of initial implant stability, use of cylindrical (non-threaded) implants and prosthetic rehabilitation with implant-supported overdentures. Moreover, it may be suggested that the following situations may be correlated with an increase in the implant failure rate: use of the non-submerged technique, immediate loading, implant insertion in fresh extraction sockets, smaller diameter implants. Some recently published studies suggest that modern, moderately rough implants may present with similar results irrespective if placed in maxillas, in smoking patients or using only short implants.

Long-term effectiveness of a prefabricated oral appliance for myofascial pain
- 2012
-
Ingår i: Journal of Oral Rehabilitation. - : John Wiley & Sons. - 1365-2842 .- 0305-182X. ; 39:4, s. 252-260

Tidskriftsartikel (refereegranskat)abstract
- Summary The long-term effectiveness of a prefabricated oral appliance (R) was compared with a stabilisation appliance (S) in patients with myofascial pain. Sixty-five patients diagnosed with myofascial pain at two centres for Stomatognathic Physiology in Sweden and Finland were included in a randomised controlled trial using Research Diagnostic Criteria for Temporomandibular Disorders, with history questionnaires and clinical examinations performed by blinded examiners at baseline and at 6- and 12-month follow-ups. Patients were randomly assigned either to the R or the S group. Treatment outcome was measured according to IMMPACT for four chronic pain outcome domains: pain intensity, overall improvement, physical functioning and emotional functioning. Physical functioning was classified for Graded Chronic Pain severities and assessed by the Jaw Functional Limitation scale. Emotional functioning composed of scores of non-specific physical symptoms and depression. There were no differences between groups at baseline. At both follow-ups, all outcome domains showed significant within-group improvement, without significant differences between groups. At 12 months, 72% of all patients reported a 30% reduction in worst pain and 63% of the patients a 50% reduction in worst pain. Overall improvement ‘better’ to ‘symptom-free’ was observed in 81% in the R and 64% in the S group at the 12-month follow-up. Graded Chronic Pain, Functional Limitation of the Jaw, non-specific physical symptoms and depression showed statistically significant reduction at 12-month follow-up. Results support the hypothesis that the effectiveness of the prefabricated appliance is similar to that of the stabilisation appliance in the long-term when treating patients with myofascial pain.

- Jaw actions adapt to the changing properties of food that occur during a masticatory sequence. In the present study, we investigated how the time-varying activation profile of the masseter muscle changes during natural chewing in humans and how food hardness affects the profile. We recorded surface electromyography (EMG) of the masseter muscle together with the movement of the lower jaw in 14 healthy young adults (mean age 22) when chewing gelatin-based model food of two different hardness. The muscle activity and the jaw kinematics were analysed for different phases of the chewing cycles. The increase in the excitatory drive of the masseter muscle was biphasic during the jaw-closing phase showing early and late components. The transition between these components occurred approximately at the time of tooth-food contact. During the masticatory sequence, when the food was particularised, the size of the early component as well as the peak amplitude of the EMG significantly decreased along with a reduction in the duration of the jaw-closing phase. Except for amplitude scaling, food hardness did not appreciably affect the muscle's activation profile. In conclusion, when chewing food during natural conditions, masseter muscle activation adapted throughout the masticatory sequence, principally during the jaw-closing phase and influenced both early and late muscle activation components. Furthermore, the adaptation of jaw actions to food hardness was affected by amplitude scaling of the magnitude of the muscle activity throughout the masticatory sequence.

Attitudes of final-year dental students to bleaching of vital and non-vital teeth in Cardiff, Cork, and Malmö
- 2011

Tidskriftsartikel (refereegranskat)abstract
- The aim of this study was to determine attitudes of final-year dental students in Cardiff, Cork and Malmö towards tooth whitening. Following receipt of ethical approval, pre-piloted questionnaires were distributed to final-year dental students in Cork, Cardiff, and Malmö as close as possible to graduation. The questionnaire sought information relating to various opinions and attitudes towards the use of bleaching techniques including safety of bleaching, confidence in the provision of bleaching, recommendations to patients, teaching received, awareness of restrictions on the use of bleaching products and management of simulated clinical scenarios. Eighty three per cent (n = 116) of questionnaires were returned. Cork dental students had the most didactic teaching (2- h vital, 1- h non-vital bleaching) compared to Cardiff or Malmö students (0 h each). More Cork students regarded bleaching as safe (76%, n = 28) than Cardiff (70%, n = 32) or Malmö (36%, n = 12) students. More than 50% of Cork students feel they know enough about bleaching to provide it in practice, significantly more than Cardiff (<25%) or Malmö (<25%) students. The majority of students would provide vital bleaching after qualification (100% (n = 37) Cork; 82% (n = 27) Malmö; 76% (n = 35) Cardiff). In simulated clinical scenarios, more Cork students would propose bleaching treatments (89%n = 33) than Malmö (64%n = 21) or Cardiff (48%n = 22) students. Variations exist in the attitudes and approaches of three European dental schools towards bleaching. Dental students need to be best prepared to meet the needs of their future patients.

Tidskriftsartikel (refereegranskat)abstract
- The purpose of the study was to estimate in vitro material degradation in implants and cobalt-chrome or titanium frameworks, before and after exposure to artificial saliva. Four full-arch implant frameworks were fabricated according to the Cresco™ method (Astra Tech AB, Mölndal, Sweden), two in a cobalt-chrome alloy and two in commercially pure (CP) titanium. They were cut vertically, and the three central sections of each framework were used. Element leakage into an artificial saliva solution was observed with mass spectrometry. Before artificial saliva exposure, three Brånemark System(®) implants (Nobel Biocare AB, Gothenburg, Sweden) were screw-retained to cobalt-chrome sections, and three to titanium sections. The contact surfaces with the implants of the framework sections and the corresponding surfaces of six implants were examined with optical interferometry before and after exposure to artificial saliva to evaluate material degradation. Conventional descriptive statistics were used to present the mass spectrometry and interferometry data. One-way anova and Dunnett's T3 post hoc test were used to identify and study differences between the groups. To highlight changes within the groups, the Student's t-test was used. The significance level was set at 5%. There was significantly more leakage of cobalt elements than of titanium and chrome (P < 0·05). After saliva exposure and framework connection, the implants roughened (P < 0·05). The titanium frameworks were generally rougher than the cobalt-chrome frameworks, both before and after saliva exposure (P < 0·05). The findings in this study suggest active material degradation processes for both implants and framework materials.

Forskningsöversikt (refereegranskat)abstract
- The purpose of this systematic review was to describe the prevalence of whiplash trauma in patients with temporomandibular disorders (TMDs) and to describe clinical signs and symptoms in comorbid TMD/whiplash compared with TMD localised to the facial region. A systematic literature search of the PubMed, Cochrane Library and Bandolier databases was carried out for articles published from 1 January 1966 to 31 December 2012. The systematic search identified 129 articles. After the initial screening of abstracts, 32 articles were reviewed in full text applying inclusion and exclusion criteria. Six studies on the prevalence of neck trauma in patients with TMD met the inclusion criteria and were included in the review. Two of the authors evaluated the methodological quality of the included studies. The reported prevalence of whiplash trauma ranged from 84% to 70% (median 35%) in TMD populations, compared with 17-13% in the non-TMD control groups. Compared with patients with TMD localised to the facial region, TMD patients with a history of whiplash trauma reported more TMD symptoms, such as limited jaw opening and more TMD pain, and also more headaches and stress symptoms. In conclusion, the prevalence of whiplash trauma is higher in patients with TMD compared with non-TMD controls. Furthermore, patients with comorbid TMD/whiplash present with more jaw pain and more severe jaw dysfunction compared with TMD patients without a history of head-neck trauma. These results suggest that whiplash trauma might be an initiating and/or aggravating factor as well as a comorbid condition for TMD.

Confirmatory factor analysis of the Oral Health Impact Profile
- 2014
-

Tidskriftsartikel (refereegranskat)abstract
- Previous exploratory analyses suggest that the Oral Health Impact Profile (OHIP) consists of four correlated dimensions and that individual differences in OHIP total scores reflect an underlying higher-order factor. The aim of this report is to corroborate these findings in the Dimensions of Oral Health-Related Quality of Life (DOQ) Project, an international study of general population subjects and prosthodontic patients. Using the projects Validation Sample (n = 5022), we conducted confirmatory factor analyses in a sample of 4993 subjects with sufficiently complete data. In particular, we compared the psychometric performance of three models: a unidimensional model, a four-factor model and a bifactor model that included one general factor and four group factors. Using model-fit criteria and factor interpretability as guides, the four-factor model was deemed best in terms of strong item loadings, model fit (RMSEA = 0.05, CFI = 0.99) and interpretability. These results corroborate our previous findings that four highly correlated factors - which we have named Oral Function, Orofacial Pain, Oro-facial Appearance and Psychosocial Impact - can be reliably extracted from the OHIP item pool. However, the good fit of the unidimensional model and the high interfactor correlations in the four-factor solution suggest that OHRQoL can also be sufficiently described with one score.
