This systematic review followed the PRISMA guidelines. An extensive literature search was conducted in the following databases: MEDLINE, Embase, CINAHL, Web of Science, and Cochrane from inception until December 20, 2024. Studies targeting individuals between 7 and 18 years old, diagnosed with malocclusions, and receiving orthodontic treatment were included. A meta-analysis (odds ratio) was performed considering the number of individuals with and without headache, who did and did not undergo orthodontic treatment. The quality of studies was assessed using the Quality in Prognosis Studies (QUIPS) tool. Finally, the overall certainty of the evidence was assessed by the GRADE approach. Seven studies met the inclusion criteria with a pooled sample size of 1.141 individuals. No statistically significant difference in the prevalence of headache was found between children who received orthodontic intervention compared to no treatment (OR 1.22 [CI 0.78; 1.92]; <i>p</i> = 0.38). Children with malocclusion who were treated orthodontically had significantly fewer headaches after treatment compared to untreated children with class II malocclusion (OR 0.42 [CI 0.19; 0.92]; <i>p</i> = 0.03). All studies had a high risk of bias, and the certainty of evidence was very low. In summary, no increased prevalence of headaches was detected during or after orthodontic interventions in children and adolescents with malocclusions when compared to those who did not receive orthodontic treatment. Instead, children with malocclusion treated orthodontically had significantly fewer headaches after treatment compared to untreated children with malocclusion.

A literature search was carried out using six electronic databases to identify studies that compared the sagittal lateral cephalometric measurements in females with TS, with the last search performed in February 2024. Studies were selected according to the following inclusion criteria: an experimental group of individuals with TS compared to a control group of females without TS; with sagittal cephalometric characteristics evaluated on lateral cephalometric radiographs. Sagittal cephalometric variables measured in three or more studies were put to meta-analysis, using the random-effects model. Subgroup meta-analyses were also carried out based on karyotype. A modified version of the AXIS tool was used to assess the risk of bias in the included studies. From the initial 199 records identified, 17 studies and 11 sagittal cephalometric variablesere analysed. Four hundred and seventeen unique patients with TS, coming from 10 different European countries, were included. All of the sagittal linear variables compared, namely S-N, N-Ba, Go-Gn, Go-Pg and ANS-PNS, were significantly reduced in those with TS. Concerning the six angular variables compared, the A-N-B angle showed no difference between the groups, whereas the S-N-A, S-N-B and S-N-Pg angles were significantly reduced, and the N-S-Ba and the N-S-Ar angles significantly increased in those with TS. The subgroup meta-analyses for karyotype consistently revealed mean differences much greater than the norm for the 45,X karyotype group than those of the mosaic and isochromosome karyotypes. The sagittal lateral cephalometric characteristics of females with TS differ significantly from those of nonsyndromic females, with the greatest deviation from the norm displayed in the 45,X karyotype. Bimaxillary retrognathia and reduced anterior cranial base and maxillary and mandibular lengths were observed, without this resulting, however, in any difference with regard to the sagittal intermaxillary relationships for the females with TS.

The aim of this scoping review was to collate and synthesise the evidence related to the quality of information (QOI) about orthodontic-related videos uploaded to YouTube. The preferred reporting items for systematic reviews and meta-analyses extension for scoping reviews guidelines were employed by two independent researchers to search and screen the literature over four electronic databases. The study topics were assigned into one of five general categories: ‘Appliances’, ‘Orthodontic conditions’, ‘Orthodontics’, ‘Quality of life’ and ‘Treatment techniques and auxiliaries’. The searches initially returned 82 unique records. A total of 35 cross-sectional studies, evaluating 3129 videos with more than 181,563,304 views, were identified for systematic appraisal after the application of selection criteria. The findings indicated that YouTube plays a prominent role in the provision and sharing of orthodontic-related information. Although the information provided by orthodontic treatment providers was of slightly higher quality, the overall quality of all orthodontic information was generally poor. The studies covered a wide range of orthodontic-related subjects, with those related to appliances, especially clear aligners, being commonplace. Evaluation of the QOI frequently involved the use of the modified DISCERN, video information quality index (VIQI) and global quality score (GQS) tools. Content analysis was employed in most studies, but there was considerable heterogeneity in the use and reporting of this approach.
