Floating-Harbor syndrome (FHS) is an extremely rare genetic disorder connected with a distinctive facial appearance, various skeletal malformations, delayed bone age, and expressive language delays. It is caused by heterozygous mutations in the Snf2-related CREBBP activator protein (SRCAP) gene. The aim of this paper is to describe the case of a 14-year-old male with FHS, referring to a review of the literature, and to collect all reported symptoms. In addition, the orthodontic treatment of the patient is described. For this, the electronic databases PubMed and Scopus were searched using the keyword "Floating-Harbor syndrome". Similar to previous cases in the literature, the patient presented with short stature; a triangular face with a large bulbous nose; deep-set eyes and narrow eyelid gaps; a wide mouth with a thin vermilion border of the upper lip; and dorsally rotated, small ears. They also presented some less-described symptoms, such as macrodontia and micrognathia. Moreover, mild mental retardation, microcephaly, and delayed psychomotor development were found. On the basis of an extraoral, intraoral examination, X-rays, and CBCT, he was diagnosed with overbite, canine class I and angle class III, on both sides. To the best of our knowledge, orthodontic treatment of this disease has not been assessed in detail so far, so this is the first case.

Review
BACKGROUND
Posterior intrusion with skeletal anchorage is one of the effective methods in the treatment of anterior open bite. Knowing the effects of posterior intrusion, the amount of possible molar intrusion using skeletal anchorage, and its impact on clinical and cephalometric indicators can help the clinician choose the optimal treatment method, especially in borderline surgical cases.
METHODS
In this systematic review, a series of articles were collected through a systematic search in databases, and the titles and summaries of all these articles were reviewed. After removing the irrelevant articles, the full texts of the related articles were read carefully, and their validity was evaluated. Only RCTs and observational studies that complied with PICO questions were included. The Cochrane Risk of Bias 2.0 (RoB 2), ROBINS-I, and GRADE were used to assess the risk of bias in the included studies. The relevant information on selected articles was extracted, and a meta-analysis was performed with Review Manager 5.4 software.
RESULTS
The meta-analysis revealed a significant average molar intrusion of 2.89 mm using temporary anchorage devices (TADs). A subgroup analysis showed that miniplates achieved greater intrusion (3.29 mm) compared to miniscrews (2.25 mm) (=0.03). The level of applied force did not significantly affect the degree of intrusion. Dental parameters such as overbite and overjet were notably altered, with overbite increasing by 4.81 mm and overjet decreasing by 2.06 mm on average. As for the skeletal cephalometric characteristics, SNB, ANB, and SN-Pog increased while mandibular plane angle and lower anterior facial height (LAFH) decreased, and these changes were significant. Meanwhile, SNA and palatal angle changes were not significant.
CONCLUSION
TADs have proved effective in achieving significant intrusion of maxillary molars, leading to marked improvements in dental and skeletal characteristics in patients with open bite malocclusion. Miniplates proved more effective in achieving greater intrusion.

BACKGROUND
Skeletal class III malocclusion is a challenging condition that orthodontists frequently come across. The facemask (FM) is a device commonly used to treat this malocclusion. However, the stability of this orthopedic correction remains unclear, and collective documentation of the short-, mid-, and long-term stability after FM therapy is necessary.
AIM
The aim of the systematic review was to assess posttreatment stability following FM therapy in patients with skeletal class III malocclusion.
MATERIALS AND METHODS
Through a predefined search strategy, electronic searching was conducted in PubMed, Latin American and Caribbean Health Sciences Literature (LILACS), Cochrane, Ovid, Embase, Scopus, and Web of Science until 30 June 2022. Eligible study selection, data extraction, and evaluation of the risk of bias were performed independently by two review authors according to the Cochrane tool for assessing the risk of bias in randomized trials (RoB 2.0 tool) and the Risk of Bias in Nonrandomized Studies-of Interventions (ROBINS-I) tool for nonrandomized trials. A total of 14 studies were finally considered eligible. The systematic review revealed that the maxillo-mandibular differential reverted to class III. The maxillary changes achieved were variable, with SNA angles ranging between -0.7° and 1.9°. Changes in the mandible were greater with an increase in the SNB angle ranging between 0.33° and 3.62°. The lower anterior facial height increased. The maxillary and mandibular incisors were proclined, and the overjet and overbite decreased. The soft tissue changes were insignificant.
CONCLUSION
The effects of FM therapy were found to be stable in the short-term follow-up period. The long-term follow-up revealed that the effects of FM therapy remained stable for the maxilla. However, the mandible continued to grow in a horizontal and unfavorable direction until the adolescent growth spurt.
CLINICAL SIGNIFICANCE
The major variable that determines the long-term success of FM therapy is the amount and direction of mandibular growth during the adolescent growth spurt. More focus on restricting unfavorable mandibular growth and duration of retention is needed for post-FM therapy.

Meta-Analysis Review
OBJECTIVE
To compare dental caries, oral hygiene, periodontal status, bruxism, malocclusion, tooth loss, and salivary alterations between autistic and typical developing individuals.
MATERIAL AND METHODS
Observational studies presenting clinical measures of oral outcomes between autism spectrum disorder (ASD) individuals and controls. EMBASE, LILACS, PubMed, PsycINFO, Scopus, Web of Science, Google Scholar, and ProQuest were searched up to June 26, 2023. Pairs of reviewers independently conducted study selection, data extraction, and assessments of methodological quality and certainty of evidence. Meta-analyses of standardized mean differences (SMD) and risk ratio (RR) were performed.
RESULTS
A total of 47 studies comprising 6885 autistic individuals were included in the review. Autistic individuals had significantly higher severity of dental-caries experience in primary teeth (SMD 0.29, 95%CI 0.02, 0.56), of dental plaque presence (SMD 0.59, 95%CI 0.24, 0.94), and of gingivitis (SMD 0.45, 95%CI 0.02, 0.88). Autistic individuals showed higher probability of occurrence of gingivitis (RR 1.34, 95%CI 1.08, 1.66,), bruxism (RR 4.23, 95%CI 2.32, 7.74), overjet (RR 2.16, 95%CI 1.28, 3.64), overbite (RR 1.62, 95%CI 1.02, 2.59), crossbite (RR 1.48, 95%CI 1.02, 2.13), and openbite (RR 2.37, 95%CI 1.46, 3.85), when compared to neurotypical individuals. Most estimates showed a small effect size with very low certainty of evidence.
CONCLUSION
Autistic individuals show worse oral health status than controls.
CLINICAL RELEVANCE
The findings reported herein can help to build health policies to better serve autistic individuals including prevention actions and access to specialized dental care.

Review
Mandibular advancement devices (MADs) remain a popular non-invasive treatment modality for the management of obstructive sleep apnea (OSA). However, the occlusal side effects from long-term therapy may result in poor patient compliance and patient drop-outs. Hence, knowledge of the possible side effects of these devices on occlusion is necessary. This article attempts to systematically review the evidence available in support of the possible long-term effects of mandibular advancement therapy on occlusion in adult sleep apnea patients. A detailed search was conducted for unpublished and published literature and their references in various electronic databases. A grey literature search was also performed. Studies until June 30, 2022, were selected. Randomized controlled trials, non-randomized trials, and cohort studies investigating the occlusal side effects of MADs for the treatment of snoring or OSA with a follow-up of at least four years were included. Study selection, data extraction, and risk of bias assessment were performed individually and in duplicate. The risk of bias was assessed by Cochrane tools for randomized and non-randomized studies. Fourteen studies were selected for the final qualitative analysis. The side effects reported were upper incisor retroclination, lower incisor proclination, decreased overjet and overbite, and change in the total occlusal contact area. The review concludes that long-term MAD therapy has statistically and clinically significant effects on occlusion.

Meta-Analysis Review
The purpose of this study was to investigate the scientific evidence on the short- and long-term effects of orthodontic correction of anterior open bite (AOB) using skeletal anchorage (SA). Clinical studies on the use of SA for AOB in patients with permanent dentition, or at least 12 years of age, were searched. Short- and long-term (≥2 years) outcomes were collected. Mean differences were calculated from pooled data. Twenty-four eligible articles with a total of 362 subjects were selected for inclusion in the meta-analysis. There was a significant increase in overbite (3.88 mm, P < 0.001) and maxillary molar intrusion (-2.15 mm, P < 0.001). The mandible showed counterclockwise rotation with anterosuperior chin movement (all P < 0.001). Long term, the decrease in overbite was 19.9% and decrease in molar intrusion was 22.9%. The decrease in the mandibular projection was 14.6% for ANB (A-point-nasion-B-point angle) and 46.2% for mandibular anteroposterior position. The overall risk of bias in the included studies was rated as moderate to high, and publication bias existed for several key variables. SA for maxillary molar intrusion effectively improved dental and skeletal outcomes, but there was a long-term decrease in overbite and maxillary molar position. The variable data quality, heterogeneity, and publication bias in investigated outcomes are limitations in interpreting the findings.

Meta-Analysis
BACKGROUND AND OBJECTIVE
The genetic basis of dentoalveolar characteristics has been investigated by several studies, however, the findings are equivocal. The objective of this systematic review and meta-analysis was to evaluate the heritability of dental arches and occlusal parameters in different stages of human dentition.
SEARCH METHODS
Electronic databases PubMed, Embase, Scopus, Web of Science, and Dentistry and Oral Science Source were searched up to August 2023 without the restriction of language or publication date.
SELECTION CRITERIA
Empirical studies investigating the heritability of dentoalveolar parameters among twins and siblings were included in the review.
DATA COLLECTION AND ANALYSIS
Study selection, data extraction, and risk of bias assessment were performed independently and in duplicate by two authors and a third author resolved conflicts if needed. Joanna Briggs Institute's critical appraisal tool was used to evaluate the risk of bias among studies and the certainty of evidence was assessed using the Grading of Recommendation, Assessment, Development, and Evaluation (GRADE) criteria.
RESULTS
Twenty-eight studies were included in the systematic review, of which 15 studies reporting heritability coefficients in the permanent dentition stages were deemed suitable for the meta-analysis. Random-effects meta-analyses showed high heritability estimates for maxillary intermolar width (0.52), maxillary intercanine width (0.54), mandibular intermolar width (0.55), mandibular intercanine width (0.55), maxillary arch length (0.76), mandibular arch length (0.57), and palatal depth (0.56). The heritability estimates for the occlusal parameters varied considerably, with relatively moderate values for crossbite (0.46) and overbite (0.44) and low values for buccal segment relationship (0.32), overjet (0.22), and rotation and displacement of teeth (0.16). However, the certainty of evidence for most of the outcomes was low according to the GRADE criteria.
CONCLUSIONS
Based on the available evidence, it can be concluded that the dental arch dimensions have a high heritability while the occlusal parameters demonstrate a moderate to low heritability.

Meta-Analysis Review
BACKGROUND/AIM
Individuals with special healthcare needs (SHCN) are more likely to sustain traumatic dental injuries (TDIs) due to distinct risk factors. The aim of this review was to assess various risk factors associated with TDIs in individuals with SHCN.
MATERIALS AND METHODS
The protocol was designed according to the recommendations of the Cochrane-handbook, Joanna Briggs Institute, and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and registered in PROSPERO (CRD42022357422). A comprehensive search was performed in PubMed, LILACS, Web of Science, EMBASE and Scopus using a pre-defined strategy without any limitation of language and year of publication. It was last updated on 25 April 2023. Studies addressing the TDIs in individuals with SHCN were included. Data extraction and analyses were performed, risk of bias (ROB) assessment was done using the Joanna Briggs Institute's critical appraisal tool, and a meta-analysis was performed using random-effects model.
RESULTS
A total of 21 studies were included in the review. They were categorized according to the target disease/condition: cerebral palsy (n = 5), ADHD and autism spectrum disorders (n = 5), visually impaired (n = 4), and multiple disorders (n = 7). The studies showed variability in the design and methods; however, 17 out of 21 studies showed moderate to low ROB. Increased overjet and lip incompetence were the main risk factors reported in the studies. The commonest injuries were observed to be enamel and enamel and dentine fractures.
CONCLUSION
The overall pooled prevalence of TDI in individuals with special healthcare needs was 23.16% with 20.98% in males and 27.06% in females. Overjet >3 mm and inadequate lip coverage were found to be associated with a higher risk of TDI in all the categories of individuals with special healthcare needs except ADHD and ASD. Falls at home in cerebral palsy, falls while walking and self-harm in ADHD and ASD, falls at home and collision in visual impairment, and unspecified falls in multiple disorders could be identified as the most common cause of TDI.

Meta-Analysis Review
OBJECTIVES
The aim of this article is to establish a comprehensive nationwide prevalence of malocclusion traits on the sagittal, vertical, and transverse planes of space in the Turkish population.
MATERIAL AND METHODS
A systematic search of PubMed, Scopus, and Web of Science was supplemented by manual searches of Google Scholar and the reference lists of included studies. Original Turkish health studies of any age were included. Strengthening the Reporting of Observational Studies in Epidemiology assessed study quality and bias (STROBE). Sagittal, vertical, and transverse malocclusion features were retrieved and gathered.
RESULTS
Eleven studies were selected from 434 titles. Two studies showed a high risk of bias, eight low and one moderate. Thirteen thousand two hundred seventy-one individuals were investigated from early childhood to late adulthood. Most studies were sampled from universities and dental (nonorthodontic) clinics. The pooled malocclusion prevalence was 56% for Class I (95% confidence interval (CI): 44-68%), 31% for Class II (CI: 6-42%), and 11% for Class III (CI: 21-37%). The other common types of malocclusions were crowding (41%, CI: 18-65%), overjet (34%, CI: 21-50%), negative overjet (13%, CI: 7-20%), and crossbite (11%, CI: 7-15%). Additionally, there was no significant difference in Class I (relative risk [RR] = 1.00, [0.96-1.05]), Class II ([RR] = 0.97, [0.92-1.03]), and Class III ([RR] = 1.08, [0.96-1.225]) malocclusion by gender.
CONCLUSIONS
This study showed Class I malocclusion has a high prevalence among the Turkish population followed by Class II and Class III malocclusions. In addition, crowding and overjet were the most prevalent malocclusions among Turkish individuals. There were no significant differences in the prevalence of malocclusions between males and females.

European Journal of Orthodontics Sep 2023To systematically review the available evidence concerning the risk factors for gingival recessions (GR) after orthodontic treatment (OT).
BACKGROUND/OBJECTIVES
To systematically review the available evidence concerning the risk factors for gingival recessions (GR) after orthodontic treatment (OT).
DATA COLLECTION AND ANALYSIS
Data was obtained and collected by systematically searching 3 data bases: Pubmed, EMBASE, and Web of Science until 20 April 2023. Controlled trials, cohort, case-control or cross-sectional studies describing GR or clinical crown height (CCH) after OT were included. The risk of bias in the selected studies was evaluated with the methodological index for non-randomized studies.
RESULTS
Forty-eight articles were included, investigating the following six risk factors for GR: 1. OT (n = 21), 2. Type of orthodontic intervention (n = 32), 3. Patient's baseline occlusal and skeletal characteristics (n = 14), 4. Mucogingival characteristics (n = 10), 5. Oral hygiene (n = 9), and 6. Others (n = 12). Significantly higher prevalence, severity and extent of GR were found in orthodontic patients by 10/15, 4/10, and 2/2 articles respectively. 10/16 articles reported significantly more GR and increased CCH in patients where orthodontic incisor proclination was performed. The evidence surrounding maxillary expansion and orthodontic retention was too heterogeneous to allow for? definitive conclusions. Pre-treatment angle classification, ANB, overjet, overbite, arch width and mandibular divergence were found not to be associated with GR (9/14), while pre-treatment crossbite, symphysis height and width were (5/7 studies). A thin gingival biotype, presence of previous GR, baseline width of keratinized gingiva and facial gingival margin thickness were correlated with increased risk of GR after OT by nine articles, while pocket depth was not. Oral hygiene, sex, treatment duration, and oral piercings were found not to be linked with GR in orthodontic patients, while GR was reported to increase with age in orthodontic patients by 50 per cent of the articles investigating this factor. The mean risk of bias for comparative and not comparative studies was 14.17/24 and 9.12/16.
LIMITATIONS
The selected studies were quite heterogeneous regarding study settings, variables reported and included very limited sample sizes.
CONCLUSION
Although studies regarding the risk factors for GR are relatively abundant, they are very heterogeneous concerning design, studied factors, methodology and reporting, which often leads to contradictory results. Uniform reporting guidelines are urgently needed for future research.
