  • Common experiences of pain in children and adolescents - an Exploratory Factor Analysis of a questionnaire
  • 2013
  • Ingår i: Swedish Dental Journal. - 0347-9994. ; 37:1, s. 31-38
  • Tidskriftsartikel (refereegranskat)abstract
    • The aim of the study was to reduce everyday and dental treatment pain items included in the extended Children's Pain Inventory (CPI), used in a prior study on Swedish children and adolescents. Another aim was to, by means of exploratory factor analysis (EFA), expose hitherto undiscovered dimensions of the CPI pain variables and thus to improve the psychometric properties of CPI. As some pain items are relevant merely to some individuals, a new and more useful questionnaire construction would enhance the internal validity of the instrument in observational surveys. EFA was applied on the extended CPI instrument. 368 children, 8-19 years old, had answered a questionnaire comprising 10 dental and 28 everyday pain variables. These pain items were analysed using a series of sequentially implemented EFA. Interpretations and decisions on the final number of the extracted factors was based on accepted principles; Kaiser's Eigenvalue >1 criterion, inspection of the scree plot and the interpretability of the items loading. The factors were orthogonally rotated using the Varimax method to maximize the amount of variance. Of all tested EFA models in the analysis, a two, three, four, and five factor model surfaced. The interpretability of the factors and their items loading were stepwise examined; the items were modulated and the factors re-evaluated. A four factor pain model emerged as the most interpretable, explaining 79 % of the total variance depicting Eigenvalues >1.014. The factors were named indicating the profile of the content: Factor I cutting trauma to skin/mucosal pain, Factor II head/neck pain, Factor III tenderness/blunt trauma pain, Factor IV oral/dental treatment pain.

  • Changes in molar position with missing opposed and/or adjacent tooth: a 12-year study in women
  • 2012
  • Ingår i: Journal of Oral Rehabilitation. - 0305-182X. ; 39:2, s. 136-43
  • Tidskriftsartikel (refereegranskat)abstract
    • Summary  The aim of this study was to radiographically analyse long-term changes in (i) overeruption of unopposed molars and (ii) tipping of molars with a mesial edentulous space, and whether there is an interaction between the two events. A further aim was to analyse if loss of alveolar bone height might influence overeruption and tipping. The sample consisted of panoramic radiographs taken at an interval of 12 years of 292 subjects from a prospective population study of women. The panoramic radiographs were scanned and analysed. Changes in tipping, overeruption and alveolar bone height of molars and control teeth were measured. The results showed that unopposed molars were more commonly found in the upper jaw and that unopposed molars showed 4·9 times higher risk of overeruption of ≥2 mm (95% CI 1·5-15·3) than opposed molars during the 12-year observation period. The average overeruption for the unopposed molars was 4·5% (s.d. 7·6), which corresponds to approximately 0·9 mm. The degree of overeruption increased with decreased bone support. Molars with a mesial edentulous space were most prevalent in the lower jaw, but neither an edentulous space nor alveolar bone level/bone level change were found to have a significant effect on tipping of the molars. The average mesial tipping was 0·8° (s.d. 5·6). In conclusion, unopposed molars showed a significantly increased risk for overeruption. Molars facing a mesial edentulous space showed a low risk for mesial tipping, but a significant interaction between overeruption and tipping was identified.

  • Molar position associated with a missing opposed and/or adjacent tooth: a follow up study in women
  • 2013
  • Ingår i: Swedish Dental Journal. - 0347-9994. ; 37:2, s. 97-105
  • Tidskriftsartikel (refereegranskat)abstract
    • The purpose of the study was to assess (i) the degree of overeruption of molars lacking opposed teeth and (ii) the inclination of molars with a mesial edentulous space and also to study (iii) changes during a 12 year period. The subject sample originated from the prospective population study of women in Gothenburg, Sweden where scanned panoramic radiographs taken with an interval of 12 years were analysed. Tipping as well as overeruption were scored on the two images according to a five-level scale. Sixty-seven subjects fulfilled the inclusion criteria at baseline and were referred to as "the non-extraction group". Further 35 subjects had lost the opposed and/or the adjacent tooth/teeth during the 12-year follow-up period: "the extraction-group". These groups were studied separately and a comparison between these groups was performed. The prevalence of molars tipped more than 15 degrees at baseline was 17.1 % in the upper jaw and 44.3 % in the lower jaw, in the non-extraction group. At baseline overeruption was seen in 25 % of the unopposed upper molars and none of lower molars in the non-extraction group. The prevalence of tipping and overeruption was statistical significant less in the extraction group (P<0.01), than in the non-extraction group at baseline, but at follow-up no statistical significant group differences existed. -The prevalence of tipped molars facing a mesial edentulous space and overerupted unopposed molars increased in adults during the 12-year period but the changes were small. -Overeruption and tipping is most pronounced immediately after extractions.

  • Validation of the Swedish Version of the Clinical Outcomes in Routine Evaluation Outcome Measure (CORE-OM).
  • 2012

  • Tidskriftsartikel (refereegranskat)abstract
    • The purpose of this study was to perform an initial validation of a Swedish translation of the Clinical Outcomes in Routine Evaluation Outcome Measure (CORE-OM). The CORE-OM is a broad self-report instrument of psychological problems, designed as an outcome measure for evaluating the effects of psychological therapy. Participants included a non-clinical group of 229 university students and a clinical group of 619 persons from four primary care sites. The Swedish CORE-OM showed excellent acceptability, high internal consistency and test-retest reliability, as well as acceptable convergent validity. There was strong differentiation of the clinical and non-clinical samples, with the clinical group scoring significantly more psychological problems than the non-clinical group. Sensitivity to change was demonstrated in psychological treatments in primary care. Overall, the psychometric characteristics of the Swedish CORE-OM were very similar to the original UK data. Nevertheless, the validity of the Swedish version needs to be examined more in detail, in larger and more diverse samples. Our results so far, however, provide support for using the Swedish CORE-OM as a psychological problems measure. To our knowledge, there are few other relatively short measures in Swedish that are free to reprint that meet the demands for psychometric properties and utility in primary care settings in which patients typically present a broad range of psychological problems. Copyright © 2012 John Wiley & Sons, Ltd. KEY PRACTITIONER MESSAGE: The Swedish version of the CORE-OM is a valid questionnaire for assessing the severity of a broad range of psychological problems.

  • Risk indicators for poor oral health in adolescents born extremely preterm.
  • 2012
  • Ingår i: Swedish dental journal. - 0347-9994. ; 36:3, s. 115-24
  • Tidskriftsartikel (refereegranskat)abstract
    • Children born extremely preterm often suffer from medical complications that have been shown to affect their oral health as toddlers and school children.The aim of this study was to investigate oral health and possible risk indicators for poor oral health in adolescents born extremely preterm compared with a control group and relate the findings to medical diagnoses at the clinical examination. Also in the same groups, compare the frequency of mineralization disturbances and its relation to postnatal morbidity and treatments. The medical records postnatally,was noted in 45 extremely preterm infants with a gestational age (GA) of <29 weeks, at 12 - 16 years of age and in age and gender matched fullterm controls with 37-43 weeks GA. A dental clinical examination was performed including a salivary examination. Medical diagnoses were noted at the time of the survey. Data from the patient dental records at 3, 6, and 9 years of age was compiled. The findings were related to gestational age, birth weight, neonatal and postnatal medical diagnoses treatments and medical diagnoses at the clinical examination. The result showed that the prevalence of plaque, gingivitis and the occurrence of Streptococcus mutans were higher among adolescents born extremely preterm compared to matched controls, and the saliva secretion was lower in the extremely preterm infants. The frequency of caries did not differ between the groups. Mineralization disturbances were more frequent in the primary dentition and more severe in the permanent dentition among the children born extremely preterm. No association between dental pathology, neonatal and postnatal morbidity and treatments was found. In conclusion, adolescents born extremely preterm have an increased number of risk indicators for a poorer oral outcome compared with the controls and more severe mineralization disturbances. These findings may imply an increased vulnerability for poorer oral health later in life.

  • Timing of mineralization of homologues permanent teeth - an evaluation of the dental maturation in panoramic radiographs.
  • 2013
  • Ingår i: Swedish Dental Journal. - 0347-9994. ; 37:3, s. 111-119
  • Tidskriftsartikel (refereegranskat)abstract
    • Clinically the condition Molar Incisor Hypomineralization (MIH), varies considerably between individuals, where any number of molars, from one to all four permanent first molars, may be affected with different degrees of hypomineralized enamel within the same dentition. An explanation to these variations could be that the start of the enamel mineralization differs between homologues teeth. The aim of this study was to compare the dental development between homologues teeth in digital panoramic radiographs (PRs), from children aged 7 to 11 years, using the Gleiser and Hunt method on second and third molars and to calculate the crown/root ratio for the mandibular premolars. 77 PRs, from individuals between 7.3 and 11.0 years of age, were studied. Differences in developmental stages between homologues teeth (second and third molars) were studied. In 72 of these PRs, the crown/root ratio of mandibular premolars was also compared. In 31 of the PRs, a difference in development was found between the right and left maxillary second molar. In 22 PRs, a difference in development between the right and left mandibular second molar was found. In 17 of the PRs, a difference in development was found between the right and left maxillary third molars. In 26 PRs, a difference in-between the right and left mandibular third molar was found. In 72 PRs, the crown/root ratio of mandibular premolars was measured and differences were found. All these differences were significant. A possible explanation to the variations in expressivity of MIH may be a result of differences in the start of mineralization between homologues teeth.

    • ObjectivesTo investigate the association between incident dementia and previous number of teeth measured over a long interval. ParticipantsWomen with (n=158) and without (n=539) dementia in 2000 to 2005. MeasurementsTooth counts in 1968-69, 1980-81, and 1992-93. Covariates included age, education, stroke, myocardial infarction, diabetes mellitus, smoking status, blood pressure, body mass index, and cholesterol level. ResultsAfter adjustment for age, odds ratios (ORs) for dementia in 2000-05, comparing first with fourth tooth count quartiles, were 1.81 (95% confidence interval (CI)=1.03-3.19) for tooth counts measured in 1968, 2.25 (95% CI=1.18-4.32) for those in 1980, and 1.99 (0.92-4.30) for those in 1992. After further adjustment for education, ORs were 1.40 (95% CI=1.03-3.19) for 1968, 1.96 (95% CI=0.98-3.95) for 1980, and 1.59 (95% CI=0.71-3.53) for 1992, and after additional adjustment for vascular risk factors, ORs were 1.38 (95% CI=0.74-2.58) for 1968, 2.09 (95% CI=1.01-4.32) for 1980, and 1.61 (95% CI=0.70-3.68) for 1992. ConclusionIn most of the analyses, lower tooth count was not associated with dementia, although a significant association was found for one of the three examinations. Further research may benefit from more-direct measures of dental and periodontal disease.

  • Demographic factors and dental health of Swedish children and adolescents
  • 2016
  • Ingår i: Acta Odontologica Scandinavica. - 0001-6357 .- 1502-3850. ; 74:3, s. 178-185

    • Abstract OBJECTIVE: To investigate the dental health of Swedish children and adolescents with reference to age, gender and residence. MATERIAL AND METHODS: Electronic dental records from 300,988 3-19-year-olds in one Swedish region were derived in a cross-sectional study in years 2007-2009. The DMFT system was used. Age was categorized into 3-6/7-9/10-12/13-15/16-17/18-19-year-olds and residence into 'metropolitan', 'urban' and 'rural' areas. ANOVA, generalized linear regression models and Fisher's exact test were used. RESULTS: Among 7-9-year-old children, nine out of 10 were free from fillings and manifest caries, while for 18-19-year-olds; this proportion was one third. Girls (18-19-year-olds) had a significantly lower risk of caries compared to boys of the same age, RR for the DT index = 0.83 (95% CI = 0.81-0.85). This pattern was reversed in 7-12-year-old children. Children and adolescents in metropolitan and urban areas had significantly more caries than subjects in rural areas, for instance the RR for the DT index in metropolitan 7-9-year-olds was 2.26 (95% CI = 2.11-2.42) compared to their rural counterparts. CONCLUSIONS: In the permanent dentition, the overall pattern revealed that girls ≤ 12 years had a higher risk of caries, while adolescent girls had a lower risk of caries, both compared with boys of corresponding ages. Living in an urban or metropolitan area entailed a higher risk of caries than living in a rural area. A greater occurrence of dental caries in adolescents than in children was confirmed. The findings should have implications for planning and evaluation of oral health promotion and disease prevention activities.

  • A new dental insurance scheme - effects on the treatment provided and costs
  • 2014
  • Ingår i: Swedish Dental Journal. - 0347-9994. ; 38:2, s. 57-66
  • Tidskriftsartikel (refereegranskat)abstract
    • The aim of this study was to investigate whether the revenues cover the costs in a pilot capitation plan, a dental insurance scheme, and to compare this capitation plan (CP) with the original fee-for-service system (FFS), in terms of the amount and type of dental care provided. Data was collected longitudinally over a period of three years from 1,650 CP patients in five risk groups at a test clinic, and from 1,609 (from the test clinic) and 3,434 (from a matched control clinic) FFS patients, in Goteborg, Sweden. The care investigated was the number of total treatments provided and the number of examinations by dentists and dental hygienists, together with preventive, restorative and emergency treatments. The economic outcome was positive from the administrator's perspective, in all risk groups for the three-year period. The amount and type of care provided differed between the payment models, as CP patients received more preventive treatments, less restorative treatments, and more examinations by dental hygienists than the FFS patients. Emergency treatment was performed more often on CP patients, and the difference was due to a higher frequency of such treatments among women in the CP group. The difference between clinics concerning certain treatment measures was sometimes greater than the difference between payment models. The results from this study indicate a net positive economic outcome for the pilot CP system over three years. The payment model and the clinic affiliation had impact on what type and amount of dental care the patients received. This might suggest that the risk of skewed selection and its consequences as well as the influence of clinic-specific practice need further investigation, to ensure economic sustainability in a longer perspective.

  • Payment systems and oral health in Swedish dental care: Observations over six years.
  • 2016
  • Ingår i: Community Dental Health. - 0265-539X. ; 33:4, s. 257-261
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: The aim of this longitudinal study of patients in regular dental care was to compare the findings of manifest caries and fillings after a 6-year adherence to either of two optional payment models, the traditional fee-for service (FFS) model, or the new capitation model 'Dental Care for Health' (DCH). Material and methods: Data on manifest caries lesions, the number of fillings and a number of background variables were collected from both a register and a questionnaire completed by 6,299 regular dental patients who met the inclusion criteria. The influence of payment system adherence and background variables on the number of manifest caries lesions at study end was examined by the means of negative binomial regression analysis. Results: The incidence rate ratio of manifest caries lesions after six years in FFS was 1.5 compared to DCH, after controlling for age, gender, education and pre-baseline caries incidence. The number of fillings was higher in FFS than in DCH at study start and at study end, and was also described by a steeper slope. Conclusions: At group level, this study showed a statistically significant difference between the caries situation after six years in DCH compared with FFS, when some important background factors, including pre-baseline caries, were kept constant in a regression model.
