- There are few cost evaluation studies of orthodontic treatment. The aim of this study was to determine the costs of correcting posterior crossbites with Quad Helix (QH) or expansion plates (EPs) and to relate the costs to the effects. To determine which alternative has the lower cost, a cost-minimization analysis was undertaken, based on that the outcome of the treatment alternatives is identical. The study comprised 40 subjects in the mixed dentition, who had undergone treatment for unilateral posterior crossbite: 20 with QH and 20 with EPs. Duration of treatment, number of appointments, broken appointments, and cancellations were registered. Direct costs (for the premises, staff salaries, material and laboratory costs) and indirect costs (loss of income due to parent's assumed absence from work) were calculated and evaluated for successful treatment alone, for successful and unsuccessful treatment and re-treatment when required. The QH had significantly lower direct and indirect costs, with fewer failures requiring re-treatment. Even the costs for successful cases only were significantly lower in the QH than in the EP group. The results clearly show that in terms of cost-minimization, QH is the preferred method for correcting posterior crossbite in the mixed dentition.

- Objective: To evaluate the evidence on three-dimensional immediate effects of rapid maxillary expansion (RME) treatment on growing patients as assessed by computed tomography/cone beam computed tomography (CT/CBCT) imaging. Materials and Methods: The published literature was searched through the PubMed, Embase, and Cochrane Library electronic databases from January 1966 to December 2012. The inclusion criteria consisted of randomized controlled trials, prospective controlled studies, and prospective case-series. Two reviewers extracted the data independently and assessed the quality of the studies. Results: The search strategy resulted in 73 abstracts or full-text articles, of which 10 met the inclusion criteria. When treating posterior crossbites with a RME device, the existing evidence points out that the midpalatal suture opening is around 20%-50% of the total screw expansion. There seems to be no consistent evidence on whether the midpalatal sutural opening is parallel or triangular. The effect on the nasal cavity dimensions after RME seems to be apparent and indicates an enlargement between 17% and 33% of the total screw expansion. Circummaxillary sutures, particularly the zygomaticomaxillary and frontomaxillary sutures and also spheno-occipital synchondrosis, appear to be affected by the maxillary expansion. Overall, however, the changes were small and the evidence not conclusive. Conclusions: CT imaging proved to be a useful tool for assessment of treatment effects in all three dimensions. The majority of the articles were judged to be of low quality, and therefore, no evidence-based conclusions could to be drawn from these studies.

Forskningsöversikt (refereegranskat)abstract
- Background: Among child and adolescent patients, persistent but untreated malocclusions may or may not have psychological and social impacts on the individual's quality of life. Objectives: To gain knowledge of malocclusions and its impact on oral health-related quality of life (OHRQOL), we conducted a systematic review of quantitative studies for evidence regarding the influence of malocclusions on OHRQOL in children and adolescents. Materials and methods: Five databases (MEDLINE via PubMed, EMBASE, Psychinfo, CINAHL, and the Cochrane Library) were searched using specified indexing terms. The following inclusion criteria were used: child or adolescent study population; healthy study participants without syndromes such as cleft lip/palate or severe illness; no previous or ongoing orthodontic treatment among participants; a focus on malocclusions and quality of life; controlled or subgrouped according to malocclusions/no malocclusions; malocclusions and/or orthodontic treatment need assessed by professionals using standardized measures; self-assessed OHRQOL estimated using validated questionnaire instruments; full-text articles written in English or Scandinavian languages. Quality of evidence was classified according to GRADE guidelines as high, moderate, or low. Results: The search produced 1142 titles and abstracts. Based on pre-established criteria, the full-text versions of 70 articles were obtained, 22 of which satisfied the inclusion criteria. After data extraction and interpretation, six publications were deemed eligible for full inclusion. All six were of cross-sectional design, and the quality of evidence was high in four cases and moderate in the remaining two. The four studies with a high level of quality reported that anterior malocclusion had a negative impact on OHRQOL, and the two with a moderate level of quality reported that increased orthodontic treatment need had a negative impact on OHRQOL. Conclusion: The scientific evidence was considered strong since four studies with high level of quality reported that malocclusions have negative effects on OHRQOL, predominantly in the dimensions of emotional and social wellbeing.

- Objectives: To compare the costs and treatment effects of headgear activator treatment of Class II malocclusion with excessive overjet between treatments started in the mixed (MD) and late mixed dentition (LMD).Trial design: Two-arm parallel-group single-centre randomized controlled trial (RCT).Material and methods: A total of 56 children presenting Class II malocclusion with excessive overjet were assessed and invited to an RCT designed as intention-to-treat. The children were randomized, by an independent person not involved in the trial into two groups, treatment with headgear activator in the MD starting at the age of 9 or to treatment with a headgear activator in LMD, starting at the age of 11. The primary outcome measure was to compare the treatment costs between the two groups. Societal costs (the sum of direct and indirect costs) were calculated for successful treatments only and when unsuccessful treatments were included. Secondary outcomes were comparisons of oral health-related quality of life (OHRQoL), dental and skeletal treatment effects, lip closure, and trauma incidence. Data collections were performed before and after treatment, corresponding to a treatment period of 2 years. Blinding was accomplished when assessing outcomes.Results: No group differences in costs were found of successful treatments or when unsuccessful treatments were included. The most pronounced treatment effects in both groups were the reduction of overjet and improved molar relation. Treatment started in MD or in LMD were equal and without significant differences regarding effects on OHRQoL, skeletal effects, lip closure, and incidence of trauma.Harms: No harm was observed, but 8 of 30 children (27%) in the MD and 6 of 21 children (29%) in the LMD group showed unsuccessful results.Limitations: Costs depend on local factors and can thereby not be directly transferred to other settings. It was a single-centre trial and can thus be less generalizable.Conclusions: Regarding costs and treatment effects, there is no difference if headgear activator treatment of excessive overjet starts in the MD or LMD.Clinical trial registration: NCT04508322.

- Purpose: The aim of this study was to assess the artefacts of 12 fixed orthodontic appliances in magnetic resonance images obtained using 1.5-T and 3-T scanners, and to evaluate different imaging sequences designed to suppress metal artefacts. Materials and Methods: In vitro, study casts of 1 adult with normal occlusion were used. Twelve orthodontic appliances were attached to the study casts and scanned. Turbo spin echo (TSE), TSE with high readout bandwidth, and TSE with view angle tilting and slice encoding for metal artefact correction were used to suppress metal artefacts. Artefacts were measured. In vivo, 6 appliances were scanned: 1) conventional stainless-steel brackets; 2) nickelfree brackets; 3) titanium brackets; 4) a Herbst appliance; 5) a fixed retainer; and 6) a rapid maxillary expander. The maxilla, mandible, nasopharynx, tongue, temporomandibular joints, and cranial base/eye globes were assessed. Scores of 0, 1, 2, and 3 indicated no artefacts and minor, moderate, and major artefacts, respectively. Results: In vitro, titanium brackets and the fixed retainer created minor artefacts. In vivo, titanium brackets caused minor artefacts. Conventional stainless-steel and nickel free brackets, the fixed retainer, and the rapid maxillary expander caused major artefacts in the maxilla and mandible. Conventional stainless-steel and nickel-free brackets caused major artefacts in the eye globe (3-T). TSE with high readout bandwidth reduced image artefacts in both scanners. Conclusion: Titanium brackets, the Herbst appliance, and the fixed retainer caused minor artefacts in images of neurocranial structures(1.5-T and 3-T) when using TSE with high readout bandwidth.(Imaging Sci Dent 20200199)

Forskningsöversikt (refereegranskat)abstract
- Objective To investigate in 10 orthodontic journals how many randomized controlled trials (RCTs) considered the Hawthorne effect, and if considered, to determine whether it was related to the patients or the therapists involved in the trial and, finally, to discuss the Hawthorne effect in an educational way. Materials and methods A search was performed on the Medline database, via PubMed, for publication type ‘randomized controlled trial’ published for each journal between 1 August 2007 and 31 July 2017. The American Journal of Orthodontics and Dentofacial Orthopedics, Angle Orthodontist, Australian Orthodontic Journal, Dental Press Journal of Orthodontics, European Journal of Orthodontics, Journal of Orthodontics, Journal of Orofacial Orthopedics, Korean Journal of Orthodontics, Orthodontics and Craniofacial Research and Progress in Orthodontics were assessed. Two independent reviewers extracted the data and identified whether the Hawthorne effect was considered or discussed in the articles and whether the Hawthorne effect was related to the behaviour of the patients, the therapists, or both. Results The initial search generated 502 possible trials. After applying the inclusion and exclusion criteria, 290 RCTs were included and assessed. The Hawthorne effect was considered or discussed in 10 of 290 RCTs (3.4%), and all were related to the patients’ and none to the therapists’ behaviour. Conclusions The Hawthorne effect reported in orthodontic RCTs was suboptimal. The researchers’ lack of knowledge about this phenomenon is evident, despite evidence that the Hawthorne effect may cause over-optimistic results or false-positive bias.

Tidskriftsartikel (refereegranskat)abstract
- Objective: To analyse in 10 orthodontic journals how many randomized controlled trials (RCTs) performed 'single-', 'double-', 'triple-', or 'outcome assessors blinding' and to evaluate, from the number of RCTs that did not conduct blinding, how many could actually have achieved it. Material and methods: Randomized controlled trials published in 10 orthodontic journals between 1 September 2012 and 28 February 2018 were included. A search was performed in PubMed and conducted for publication type 'randomized controlled trial' for each journal. Two reviewers independently analysed each RCT and registered that blinding was performed and included which specific type. It was also evaluated whether misclassifications of blinding items occurred and whether it was possible to achieve blinding among the RCTs that did not perform blinding. Results: After applying the inclusion criteria, 203 RCTs were assessed, and 61.6 per cent of them had used blinding, with the main type being 'outcome assessors blinding' (40.4%) followed by 'single-blinding' (15.3%), 'double-blinding' (2.5%), and 'triple-blinding' (3.4%). In 38.4 per cent of the trials, no blinding was performed; however, 79.4 per cent of them could have achieved blinding. Fifteen RCTs (7.3%) misclassified the blinding in relation to single-, double-, or triple-blinding. Journals followed the CONSORT (AJODO, EJO, JO, OCR) published together significantly more RCTs that performed blinding than journals not following the CONSORT. Conclusions: Blinding of outcome assessors was the most frequent type, as orthodontic trials are often of intervention design and thereby difficult to mask for patients and trial staff. The misclassifications of blinding items may indicate suboptimal knowledge among researchers and peer-reviewers regarding the definitions for diverse blinding types.
