  • 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
  • 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.

  • 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.

  • Evaluation of the Dental Hygienist Beliefs Survey; test-retest assessment in a group of general dental patients.
  • 2012
  • Ingår i: International journal of dental hygiene. - 1601-5037. ; 10:1, s. 30-35
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective:  To evaluate the Dental Hygienist Beliefs Survey (DHBS) and the test–retest reliability of DHBS in a group of general dental patients.Material and methods:  The DHBS, which is a questionnaire constructed to assess patients’ specific attitudes towards dental hygienists (DHs), was distributed together with the Dental Anxiety Scale adapted to specifically assess fear of DH treatment (DHAS). It was hypothesized that DHBS would correlate with DHAS and gender. The questionnaires were consecutively distributed to 80 patients at their first visit and after a clinical examination performed by a DH student. Retest assessments of DHBS were conducted approximately two weeks later in conjunction with the next visit at the DH student and before treatment (scaling session). The final study sample included 77 adult general dental patients in treatment at an education clinic for DH students.Results:  The results verified a statistically significant correlation between DHBS and DHAS. The DHBS sum of scores showed high internal consistency with Cronbach’s a coefficient of 0.88 and 0.91 at the first and second assessments, respectively, and the test–retest reliability of the DHBS was acceptable with intraclass correlation coefficient of 0.76. No statistically significant association was found between DHBS and gender.Conclusion:  The results suggest that the DHBS is a reliable and stable scale to use to assess patients’ specific attitudes towards DHs. Moreover, DH beliefs are associated with fear of DH treatment.

  • Phobic avoidance and regular dental care in fearful dental patients: a comparative study.
  • 2001
  • Ingår i: Acta odontologica Scandinavica. - 0001-6357. ; 59:5, s. 273-9
  • Tidskriftsartikel (refereegranskat)abstract
    • The present investigation was a comparative study of 169 highly fearful dental patients, some of whom received regular dental care (n = 28) and some who never, or only when absolutely necessary, utilized dental care (n = 141). It was hypothesized that phobic avoidance is related to anticipatory stress and anxiety reactions, negative oral health effects, psychological distress, and negative social consequences. Background factors (sex, age, education, and dental attendance pattern), dental anxiety, general fears, general state and trait anxiety, mood states, depression, and quality of life effects were studied. Data were analyzed with descriptive statistics and with exploratory factor and multiple logistic regression analysis. It was shown that dental anxiety is significantly higher among the avoiders and this is in particular evident for anticipatory dental anxiety. Oral health differed between the groups, and it was shown that avoiders had significantly more missing teeth, whereas regular attenders had significantly more filled teeth. The avoiders reported a stronger negative impact on their daily life, whereas there were no significant differences between the groups with regard to general emotions. The logistic regression analysis showed that phobic avoidance was predicted only by anticipated dental anxiety and missing teeth. It was concluded that differences between high dental fear patients with regular dental care and phobic avoidance were mainly related to anticipated fear and anxiety, oral health effects, and concomitant negative life consequences. These results are discussed in terms of subjective stress, negative cognitions, social support, and coping-strategies.

  • 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.

  • Assessment of patients with direct conditioned and indirect cognitive reported origin of dental fear.
  • 1997
  • Ingår i: European journal of oral sciences. - 0909-8836. ; 105:3, s. 213
  • Tidskriftsartikel (refereegranskat)abstract
    • This study investigated the reported conditioned or cognitive origin of dental phobia in 100 adult patients at a specialized dental phobia clinic. It was shown that a majority of patients reported a conditioned background to their dental fear. Patients' avoidance time and level of dental anxiety corresponded to previously reported data for fearful groups. Individuals with an arousal conditioning etiology of dental fear reported significantly longer avoidance time as compared to individuals with a cognitively learned reaction. With the exception of an elevated level of general fears, most psychometrically assessed emotional reactions were well within normal ranges. However, patients with a non-conditioned, cognitive etiology reported significantly higher levels of trait anxiety and fear of embarrassment. In addition, a separate analysis among women revealed a greater fear of physical injuries among patients with cognitive etiology.
