- OBJECTIVES: To assess the success rate of spontaneous space closure after extraction of the first permanent molar (FPM) in the maxilla and the mandible, and to identify the factors that make spontaneous space closure most favorable in each.MATERIALS AND METHODS: A retrospective records-based cohort study was conducted through a search of the database of the Public Dental Service, Stockholm County Council, Stockholm, for young adults born between 2000 and 2001, who underwent extraction of one or more FPM between 2006 and 2016. A total of 995 extracted teeth were identified, of which 203 teeth in 155 patients met the inclusion criteria.RESULTS: Of the 203 extracted teeth, 166 (81.8%) did not receive any orthodontic treatment. The success rate for space closure in orthodontically treated patients was 91.9%. The success rate for spontaneous space closure was 84.3%. All unsuccessful spontaneous space closure in the maxilla occurred in patients older than 12 years. The dental developmental stage of the second permanent molar (SPM) had a statistically significant association with spontaneous space closure in the mandible (P < .001).CONCLUSIONS: The success rate of spontaneous space closure was high (84.3%) and was higher in the maxilla (94.1%) than the mandible (74.1%). Age at time of extraction and dental developmental stage of the SPM were significant factors for successful spontaneous space closure in the maxilla and mandible, respectively.

- Background Malocclusions in adolescents might have a negative impact on oral health-related quality of life (OHRQoL). Potential confounding variables (confounders) such as age, gender, caries, and socioeconomic status may skew the real relationship between malocclusions and OHRQoL. Objectives To analyse the effect of malocclusions in adolescents on OHRQoL, when controlled for potential confounders. Search methods Five databases (PubMed, Cochrane Library, Cinahl, Scopus, and Web of Science) were searched up to 15 June 2022. Selection criteria Studies in which OHRQoL in 10-19-year olds with and without malocclusions were compared. Data collection and analysis Screening, data extraction, and quality assessments were performed by four investigators independently. Risk of bias was assessed according to the Swedish Agency for Health Technology Assessment and Assessment of Social Services (SBU) guidelines. To be included, studies had to control for confounders. Certainty of evidence was assessed with GRADE. Results Thirteen cross-sectional studies with low and moderate risk of bias were included in the qualitative synthesis. Four of these were also included in the quantitative synthesis (meta-analysis). The 13 studies in the qualitative synthesis displayed a large variation among the indices used for malocclusion ratings, as well as in instruments measuring OHRQoL. There was moderate quality of evidence that malocclusions have a negative effect on OHRQoL. The four articles included in the quantitative synthesis (meta-analysis) measured malocclusions with DAI and OHRQoL with CPQ 11-14 short form. There was moderate quality of evidence that malocclusions have a negative effect on OHRQoL (RR/PR 1.15, 95% CI 1.12-1.18, 3672 participants). Conclusions There is moderate quality of evidence that malocclusions in adolescents have a negative impact on OHRQoL, after taking relevant confounders into consideration. Future studies should ideally use standardized measures for malocclusion ratings and OHRQoL. Registration PROSPERO. CRD42020186152.

- OBJECTIVE: The Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) is an instrument developed for assessment of orthodontic aspects of oral health-related quality of life (OHRQoL). This study aimed to translate and validate the Swedish version of PIDAQ for use in Swedish adolescents 12-19 years of age.MATERIAL AND METHODS: The translation was made according to the process described in 'Guidelines for Establishing Cultural Equivalency of Instruments' by Ohrbach et al. Field testing was performed in a group of consecutive patients who were about to start orthodontic treatment (untreated group) and a group of consecutive patients who had recently finished orthodontic treatment (treated group).RESULTS: During the translation procedure, a Swedish version of PIDAQ was formed. In the field testing, a total of 144 questionnaires, 72 from untreated patients (mean age 14.6 years) and 72 from treated patients (mean age 17.3 years) were collected. The exploratory factor analysis detected two factors, which differs from the factor structure in the original questionnaire. The mean total PIDAQ score was significantly higher (p < .001) in the untreated group, 40.6 (20.3), than in the treated group, 9.4 (10.5), implying a high discriminant validity. Reliability was excellent, with internal consistency Cronbach's alpha values varying from 0.94 to 0.97.CONCLUSION: The Swedish version of PIDAQ demonstrates good validity and excellent reliability and is suitable for future research on the effect of malocclusion on OHRQoL in Swedish 12- to 19-year-olds.

- OBJECTIVE: and P-CPQ, and to evaluate the impact on agreement of oral health including malocclusion and background characteristics (dental fear, family situation, gender of informant).MATERIAL AND METHODS: and P-CPQ separately in connection with a clinical examination.RESULTS: The participants comprised 247 child-parent pairs: 116 (47%) boys, 131 (53%) girls, 166 (67%) mothers and 81 (33%) fathers. The agreement between the child and parental ratings of the children's OHRQoL was low, with an ICC of 0.22 (95% CI: 0.04-0.37) for the total scale.CONCLUSIONS: There was a low agreement between children's and parents' answers. For best care, it is advisable to consider perceptions of both children and parents because they can complement each other in estimating the child's OHRQoL.

Tidskriftsartikel (refereegranskat)abstract
- Objective: To examine the validity and reliability of the Swedish versions of the short-form Child Perceptions Questionnaire 11-14 (CPQ(11-14)) and Parental Perceptions Questionnaire (P-CPQ) for measuring children's oral health-related quality of life (OHRQoL).Material and methods: The sample comprised 247 children and parents. OHRQoL was assessed by asking each child and their accompanying parent to complete the relevant questionnaire. To allow test-retest analysis, 30 children and 32 parents were asked to complete the instrument a second time within 2-4 weeks.Results: In terms of construct validity, significant correlations were observed between CPQ scale scores and the global ratings of oral health and overall well-being for both the CPQ(11-14) and the P-CPQ. Regarding internal consistency, Cronbach's alphas for the total scales were 0.81 and 0.77, respectively, indicating good reliability, and internal consistency for the subscales (two or four dimensions) was acceptable. Test-retest reliability was good for the CPQ(11-14) total scale (ICC 0.77) and acceptable for the P-CPQ total scale (ICC 0.63).Conclusions: The Swedish versions of the short-form CPQ(11-14) and P-CPQ are both valid and reliable, and can be recommended for use among Swedish children aged 11-14 years for evaluation of OHRQoL.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: To compare Oral health-related quality of life (OHRQoL) among 9-year-old children with excessive overjet (EO) to children with unilateral posterior crossbite (UPC) and children with normal occlusion (NO). Materials and methods: The study sample sourced from 19 Public Dental Service Clinics in Sweden. Reported are baseline data originating from two controlled trials, one regarding UPC and the other focusing on EO. The NO children derive from the same trials. The UPC group comprised 93 children (45 boys and 48 girls), the EO group 71 children (36 boys and 35 girls), and the NO group 65 children (32 boys and 33 girls). In conjunction to a clinical examination, all children completed the Child Perceptions Questionnaire (CPQ8-10) for evaluation of OHRQoL. The CPQ8-10 comprises 25 questions grouped into four domains: oral symptoms, functional limitations, emotional, and social well-being. Validated questions about pain in the jaws and face were also included. Results: The total mean CPQ score was 5.1 for the UPC, 7.4 for the EO, and 4.4 for the NO group, showing a significant difference between the UPC and EO (P = 0.048) and between EO and NO group (P = 0.012). These differences remained when adjusted for the confounders' caries, trauma, enamel defects, and headache. No difference between UPC and NO was found. The EO children also reported significantly higher scores in the domains emotional and social well-being (P = 0.039 and P = 0.012). Limitations: The study would be strengthened if a longitudinal design had been performed. Conclusion: Children with EO reported significantly lower OHRQoL compared to children with UPC or NO. The children generally reported low CPQ scores that imply an overall fairly good OHRQoL.

Do Different Maxillary Expansion Appliances Influence the Outcomes of the Treatment?
- 2018
-
Ingår i: European Journal of Orthodontics. - : Oxford University Press. - 0141-5387 .- 1460-2210. ; 40:1, s. 97-106
-
Forskningsöversikt (refereegranskat)abstract
- Background and objectives: There is no consensus in the literature regarding which rapid maxillary expansion (RME) design or activation rate benefits the patients the most. Therefore, the primary aim of this systematic review was to see whether there is a difference in the skeletal and dentoalveolar effects of different RME appliances in children and growing adolescents. The secondary aim was to see whether these effects are different when using different activation protocols for these appliances. Data collection and analysis: The search was done in three databases (PubMed, Cochrane Library, and Web of Science). The following inclusion criteria were used: randomized controlled trial, prospective controlled studies, 15 or more patients in each study, human subjects up to 18 years of age, and RME effects had to be assessed by computed tomography/cone beam computed tomography. Study appraisal and synthesis methods: Quality of the methodology was classified according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) guidelines as high, moderate, or low. Results: The search resulted in 145 titles and abstracts; 109 of them were excluded based on pre-established criteria. Thirty-six full-text articles were assessed for eligibility and 18 of which satisfied the inclusion criteria. Finally, seven articles were deemed eligible for full inclusion and revealed that all appliances and protocols showed significant expansion in the mid-palatal suture. No evidence was found for the cause of dental tipping. Limitations: In this systematic review, having different age groups in each study and using different anatomical landmarks and outcome measures for assessing the skeletal and dental effects made it difficult to conduct a meta-analysis. Conclusions: There is moderate evidence that all designs produce significant expansion at the mid-palatal suture. However, lack of studies comparing appliances and protocols has been found. Finally, no evidence-based conclusions could be drawn about the appliance effect on teeth tipping.

Oral health-related quality-of-life among children in Swedish dental care : The impact from malocclusions or orthodontic treatment need
- 2016
-
Ingår i: Acta Odontologica Scandinavica. - : Taylor & Francis. - 0001-6357 .- 1502-3850. ; 74:2, s. 127-133

Tidskriftsartikel (refereegranskat)abstract
- Objectives: To describe oral health-related quality-of-life (OHRQoL) and the impact of malocclusions or orthodontic treatment need in a cohort of children in Swedish dental care, using the Swedish version of the Child Perceptions Questionnaire-Impact Short Form (CPQ(11-14)-ISF:16).Subjects and methods: Two hundred and fifty-seven children (mean age = 11.5 years, SD = 0.8, range = 9.8-13.5 years) completed the CPQ(11-14)-ISF:16 in conjunction with a clinical examination. In addition to malocclusions and orthodontic treatment need (based on the Index of Orthodontic Treatment Need-Dental Health Component), possible confounders (caries, enamel defects, dental trauma, headache and socio-economic markers) were recorded. Children also rated their own dental fear on the Children's Fear Survey Schedule-Dental Sub-scale (CFSS-DS).Results: The mean total CPQ(11-14)-ISF:16 score was 9.31. The logistic regression analyses revealed an impact of orthodontic treatment need on OHRQoL (CPQ), but no clear association between higher severity and higher impact on OHRQoL was seen. Dental fear and headache appeared to discriminate for poorer OHRQoL. No impact from caries, enamel defects, dental trauma, or socio-economic markers was revealed.Conclusions: This cohort of children reported good self-perceived OHRQoL. Effects on OHRQoL from malocclusions or orthodontic treatment need were limited and inconsistent. Dental fear and headache were found to be more distinct impact factors on OHRQoL than were malocclusions or orthodontic treatment need.

Malocclusions and quality of life : cross-sectional and longitudinal studies in children
- 2015
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- There are few longitudinal studies of the prevalence of malocclusionsand possible self-correction of malocclusions during the developmentof the dentition. Early intervention might be unnecessary if self-correction of the malocclusion occurs during the transition from theprimary to the permanent dentition. Most studies are cross-sectionaland in those of longitudinal design, the results are inconsistent anddifficult to interpret.Malocclusions may or may not influence the quality of life inchildren and adolescents. Thus, evaluations of the influence ofdifferent malocclusions on quality of life will certainly underpin abroader understanding and knowledge about how malocclusionsaffect the daily life of young patients. This information may also beimportant when it comes to assessing the most appropriate time forstarting orthodontic treatment, not only from a professional pointof view, but also, most importantly, from the patients’ perspective.The overall aim of this thesis was therefore to evaluate theprevalence of malocclusions, and to document changes occurringduring the development of the dentition, from the primary dentitionstage at age 3, through the mixed dentition at age 7, to the earlypermanent dentition at age 11.5 years. Further aims were to reviewthe current state of knowledge about the impact of malocclusionson oral health related quality of life (OHRQoL) and to investigatehow malocclusions affect the quality of life in a cohort of children,aged 11.5 years, whose dental care is provided by the Swedish PublicDental Service.
