- Structured Abstract ObjectivesThe aim of this qualitative study was to explore and describe adolescents experiences of treatment with removable functional appliances. Setting and sample populationPublic Dental Service, Gothenburg, Sweden. Material and methodsIndividual interviews focusing on adolescents' experiences of using a removable functional appliance were held with 21 adolescents (12 girls and nine boys). The mean age of the participants was 13.2years (range 11-15, SD 1.25) at the interview occasion. Interviews were transcribed verbatim and analysed according to a qualitative research approach, phenomenography. ResultsOutcomes of data analysis emerged in five categories with totally 12 subcategories that describe the adolescents' various conceptions of the treatment. The adolescent's experiences of using removable functional appliance appeared to have a large variation, comprising of the individual approach, feelings and strategies, the dentist role and receiving external support. ConclusionParticipants developed their own strategies of measurement to see improvement. An active involvement of the adolescents' in the treatment seems to be needed, supported by the dentist at coming appointments, using overjet measurement as a tool for motivation. Furthermore, efforts should be made by clinicians to listen and understand adolescents' needs and requirement before the treatment start.

- 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 12years 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 ≥2mm (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 0·9mm. 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.

- 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.

Tidskriftsartikel (refereegranskat)abstract
- The purpose of this study was to compare the clinical effectiveness in reducing large overjet between a prefabricated functional appliance (PFA) and a slightly modified Andresen activator (AA). A multicentre, prospective randomized clinical trial was conducted with patients from 12 general dental practices. One hundred and five patients with an Angle Class II, division 1 malocclusion and an overjet of a parts per thousand yen6mm were eligible for the study. Eight patients were excluded due to various reasons and the sample consisted thus of 97 subjects (44 girls, 53 boys) with a mean age of 10.3 years. The study was designed as intention to treat and the patients were randomly allocated by lottery to treatment with either a PFA or an AA. The PFA and AA group consisted of 57 subjects (28 girls, 29 boys) and 40 subjects (16 girls, 24 boys), respectively. Overjet, overbite, lip seal, and sagittal molar relationship were recorded before, at the end of treatment and 1-year post-treatment. Blinding was not performed. The endpoint of treatment was set to overjet a parts per thousand currency sign3mm and after this a 6 months retention period followed. No significant difference was found in overjet, overbite, sagittal relation, and lip seal between the two groups for the total observation period. The treatment of 40 (70 per cent) patients with PFA and 21 (53 per cent) with AA were considered unsuccessful mainly due to poor compliance. No cephalometric records were taken as only patient-centred clinical outcome were used as an indicator for treatment success. The criteria of reduction of overjet to as low as 3mm could have affected the success rate. No difference in effectiveness could be shown between PFAs and AAs in correcting overjet, overbite, sagittal molar relation, and lip seal. The success rate in treatment with both appliances is, however, low. This trial was registered in "FoU i Sverige" (), registration number: 97131.

- We compared facial growth in patients with bilateral complete cleft lip and palate (BCLP) in whom the palate had been repaired by the von Langenbeck procedure at the age of 14 months (L-14), or by the Wardill procedure at 18 months (W-18). A total of 151 unaffected subjects were used as a reference group. Thirty-six adult patients, 26 in the L-14 group, and 10 in the W-18 group, were investigated clinically and with lateral skull radiography, and they also filled out a questionnaire about their dental condition. Multiple linear regression was used to analyse the effect of surgical strategy, sex, and the presence of a velopharyngeal flap on several dependent variables indicating sagittal and vertical jaw relations, and inclination of incisors. The BCLP group was characterised by a pre-normal basal relation (ss-n-sm), retroclined upper (ILs/NL) and lower (ILi/ML) incisors, maxillary retrognathism (s-n-ss) in men, larger maxillary plane angle (NSL/NL) in women, larger mandibular plane (NSL/ML) and intermaxillary vertical relation (NL/ML) in men, and smaller anterior facial height (n-gn) and upper anterior facial height (n-sp). In the BCLP group, differences in outcomes could be explained only by sex. The sagittal jaw base relation (ss-n-sm) was significantly smaller in men than in women, whereas the total anterior facial height (n-gn) was greater in men. Lateral crossbite was found in about 75% of patients. About 70% were satisfied with their dental condition. The choice of surgical strategy had no significant influence on the variables measured on facial morphology.

Tidskriftsartikel (refereegranskat)abstract
- Waist-hip ratio (WHR) is a measure of body fat distribution and a predictor of metabolic consequences independent of overall adiposity. WHR is heritable, but few genetic variants influencing this trait have been identified. We conducted a meta-analysis of 32 genome-wide association studies for WHR adjusted for body mass index (comprising up to 77,167 participants), following up 16 loci in an additional 29 studies (comprising up to 113,636 subjects). We identified 13 new loci in or near RSPO3, VEGFA, TBX15-WARS2, NFE2L3, GRB14, DNM3-PIGC, ITPR2-SSPN, LY86, HOXC13, ADAMTS9, ZNRF3-KREMEN1, NISCH-STAB1 and CPEB4 (P = 1.9 × 10⁻⁹ to P = 1.8 × 10⁻⁴⁰) and the known signal at LYPLAL1. Seven of these loci exhibited marked sexual dimorphism, all with a stronger effect on WHR in women than men (P for sex difference = 1.9 × 10⁻³ to P = 1.2 × 10⁻¹³). These findings provide evidence for multiple loci that modulate body fat distribution independent of overall adiposity and reveal strong gene-by-sex interactions.

-

Tidskriftsartikel (refereegranskat)abstract
- The aim of this case series was to analyse dimensional alterations of the alveolar ridge and tooth-supporting structures, as well as root resorption, following orthodontic tooth movement into edentulous areas with reduced ridge dimensions. The study involved six subjects (30-70 years) with 10 edentulous jaw areas in the premolar regions. Clinical and radiographic examinations and 3D measurements on scanned study casts were performed at baseline, at retention, and after 1 year of (i) the edentulous area into which the tooth was moved and (ii) the established edentulous area from which the tooth was moved. The orthodontic tooth movement into an edentulous area resulted in most individuals in only minor dimensional alterations of the periodontal tissues. With regard to the width of the alveolar process, the results indicated a decreased width in the newly established edentulous area, whereas in the area into which the tooth had been moved, the width increased. In all cases, the moved tooth showed lateral root resorption on its pressure side at the level of the bone crest at time of retention, but signs of repair were noticed at the 1-year follow-up. Within the limitations of the study, it can be concluded that orthodontic tooth movement results in dimensional alterations of the edentulous ridge and that lateral root resorption is an inevitable side-effect.
