“…The prevalence of malocclusion traits in the patient and control groups in this study was in line with the normal adult population [29,30]. In the patient group, there was a tendency toward increased overjet and increased overbite, which are typical occlusal features in Finnish adults, being associated with Class II malocclusion [30].…”

Purpose The aim of this case–control study was to investigate occlusal characteristics, received orthodontic treatment, oral health-related quality of life (OHRQoL), and satisfaction with dental esthetics in adults operated due to sagittal synostosis. Methods The study group consisted of 40 adults (25 males, 15 females, mean age 27.4 years, range 18–41) who were operated due to isolated sagittal synostosis in childhood. The control group comprised 40 age and gender-matched adults. Occlusal characteristics were evaluated clinically during study visits. Information on the previous orthodontic treatment was collected from dental records. OHRQoL was measured using the 14-item Oral Health Impact Profile (OHIP-14), and satisfaction with dental esthetics was evaluated using a visual analogue scale. Results No statistically significant differences were found between the patient group and the controls in malocclusion traits (overjet, overbite, molar relationships, crossbite, scissor bite), previous orthodontic treatment, pre-treatment malocclusion diagnoses, OHIP variables, or satisfaction with dental esthetics. However, there was a tendency toward increased overjet and overbite in scaphocephalic patients. Conclusion It seems that adults with scaphocephaly operated in childhood do not differ from the average population in terms of occlusion, received orthodontic treatment, or oral health-related well-being.

“…Mouth breathing, for instance, is closely associated with an open bite. Mouth breathers may also exhibit vestibular inclination of the upper incisors and clockwise rotation of the mandible, contributing, in part, to the increased maxillary overjet [56,57] and may also exhibit deformity of the dental arches, which may lead to tooth-size/arch-length discrepancy and space problems [58,59]. Finally, the challenges involved in the management of individuals with ASD in the dental setting, may lead to the late diagnosis of malocclusions and preclude the early treatment of any occlusal alteration [60].…”

Background To estimate the prevalence of malocclusion in individuals with autism spectrum disorders (ASD) and to assess the relationship between ASD and malocclusion. Methods We searched electronic databases including PubMed, Scopus, Web of Science, Cochrane, Embase, SciELO LILACS, Proquest, OpenGrey and Google Scholar. There were no language or publication dates restrictions. Two researchers independently performed selection, data extraction and quality assessment. Quality assessment and risk of bias were evaluated through the Newcastle–Ottawa scale and ROBINS-E tool. Meta-analyses using random effect models were used to estimate pooled measures of prevalence of malocclusion characteristics in individuals with ASD and pooled odds ratio (OR) on the relationship between ASD and malocclusion characteristics. Subgroup meta-analyses were conducted according to children and adolescents, history of orthodontic treatment, and occurrence of other syndromes and medical conditions. Results Searching identified 5549 papers with 238 were selected for full assessment. Eighteen cross-sectional studies were included according to inclusion criteria. Of them, eleven studies were considered of moderate quality. A judgement of critical risk of bias occurred for thirteen studies. The most prevalent malocclusion characteristics in individuals with ASD were crowding (33%; 95% CI 22 to 44%) and increased maxillary overjet (39%; 95% CI 23 to 54%). Individuals with ASD had higher odds of Angle’s Class II (OR 1.92; 95% CI 1.36 to 2.72), Angle’s Class III (OR 2.33; 95% CI 1.29 to 4.23), open bite (OR 1.96; 95% CI 1.21 to 3.16), and increased maxillary overjet (OR 1.53; 95% CI 1.06 to 2.21) than individuals without ASD. Conclusions Angle’s Class II, Angle’s Class III, anterior open bite and increased maxillary overjet were more prevalent in individuals with ASD than those without ASD. Further high-quality studies are needed.

Objectives An assessment of orthodontic treatment duration and results allows for measurable outcomes, goal-setting, and the establishment of patient management standards. It is important information that can be utilised for educational purposes in an orthodontic postgraduate program. The aim of this study was to determine correlations of the parameters within and between the Objective Grading System (OGS), Discrepancy Index (DI) and Treatment Complexity Index (TCI) and identify those factors associated with treatment outcomes and duration. Materials and methods This retrospective cohort study involved a consecutive sampling of 242 pre- and post-treatment patient records from the postgraduate orthodontic clinic between 2013 and 2017. The cases were assessed using the DI, OGS, and TCI pre-treatment. Treatment outcomes were assessed using the OGS. Spearman’s Rank Correlation Coefficients were computed within and between the indices. Multiple and logistic regressions were used to evaluate associations between treatment outcomes and duration, respectively. Results Within DI, significant correlations (p < 0.05) were observed between overjet-overbite, overjet-occlusal relationship, overjet-crowding, overbite-anterior open bite, overbite-crowding, anterior open bite-lateral open bite, anterior open bite-crowding, lingual posterior cross bite-crowding. Within pre-OGS, significant correlations (p < 0.05) were observed between alignment-marginal ridge, alignment-occlusal relationship, alignment-root angulation, overjet-interproximal contact, marginal ridge-buccolingual inclination, marginal ridge-overjet, marginal ridge-occlusal contact, marginal ridge-occlusal relationship, overjet-occlusal contact, overjet-occlusal relationship, overjet-root angulation, occlusal relationship-root angulation, interproximal contact-root angulation. Within TCI, functional appliance correlated with orthognathic surgery (p < 0.001), rapid palatal expansion (RPE) (p = 0.005) and multidisciplinary collaboration (p = 0.001). Pre-OGS correlated with DI (p < 0.001) and TCI (p = 0.026). Cephalometric (p = 0.002) and other conditions (p = 0.031) were associated with treatment outcomes. RPE was associated with extended treatment duration (p = 0.014). Conclusions DI, OGS, and TCI exhibited weak correlations within and between indices. Cephalometric values, clinical conditions, and RPE use should be carefully considered during treatment planning.
