Meta-Analysis Review
OBJECTIVE
The aim of this systematic review and meta-analysis was to estimate the prevalence of traumatic dental injuries (TDI) in India. The secondary objective was to evaluate the prevalence rate according to the differences in gender, age, regions, type of TDI and risk factors associated with TDI.
METHODS
The PubMed, LILACS, Web of Science, Cochrane, CINHAL, and Scopus databases, along with the Public Health Electronic Library, TRoPHI and DoPHER were searched from 1 March to 15April 2019 without any restriction of language and year of publication. The qualitative synthesis was done regarding the demographics, study methods, cause of trauma, geographic location, increased overjet and inadequate lip coverage. The meta-analysis was undertaken with STATA-14 software (USA). The pooled prevalence of TDI was calculated using data extracted from 48 studies included in qualitative synthesis and meta-analysis. A sub-group meta-analysis was done by extraction of the data for age groups of 6 years and >6 years.
RESULTS
The pooled prevalence of TDI in Indian population was 13 cases in 100 individuals. The prevalence of TDI for age groups of ≤6 was 15% (males, 15%; females, 16%) and for >6 years was 12% (males, 13%; females, 8%). The most common cause of TDI was falls, and most frequent location was home. The odds ratio for occurrence of TDI and inadequate lip-coverage was 3.35 and overjet greater than 3 mm was 3.53.
CONCLUSIONS
The pooled prevalence of TDI was 13% and slightly higher in children less than 6 years of age. Inadequate lip coverage and increased overjet are the risk factors associated with TDI. Heterogeneity was observed among the studies in terms of design, variables recorded, sampling, study methods and statistical methods. Majority of them also suffered from moderate to high risk of bias.

Review
OBJECTIVE
We sought to revise, qualify and summarize the body of evidence based on current information on the known associations and risk factors for traumatic dental injury (TDI) occurrence with an overview of systematic reviews.
METHODS
Electronic searches were performed with no language nor date restrictions.According to the PECO strategy, systematic reviews that investigated participants (P) with (E) and without (O) the presentation of factors relating to TDI and these factors' association with TDI episodes (O) as primary or secondary outcomes were included. Quality assessment and bias control were carried out according to the AMSTAR 2 checklist. In cases of systematic review results of discordance, the Jadad decision algorithm was applied.
RESULTS
After titles, abstracts and full texts were read, 19 systematic reviews were included in this overview. Four were classified with critically low, eleven with low and four with moderate methodological quality, respectively. In all studies, 249 cross-sectional, 34 epidemiological surveys, 22 cohort, 9 case-control, 4 longitudinal, 3 ecological and 30 unspecified studies were included. Male gender, child age, greater overjet, inadequate lip coverage, anterior open bite, caries in the permanent dentition, overweight, a previous history of TDI, tongue piercing, the use of alcoholic beverages and participation in sports were all associated with a greater chance of suffering TDI.
CONCLUSIONS
Sociodemographic, clinical and environmental factors are associated with a greater chance of TDI occurrence. However, most of the systematic reviews included were of a low quality and may not provide an accurate and comprehensive summary of the available research that addresses the question of interest. Well-designed primary studies on different aspects of TDI are encouraged to provide higher quality scientific evidence.

Review
BACKGROUND
Malocclusion is a highly prevalent public health problem, and several studies have shown its negative correlation with quality of life, self-esteem, and social perceptions. However, its association with bullying is still controversial.
OBJECTIVES
To evaluate the relationship between malocclusion and bullying in children and adolescents.
SEARCH METHODS
The databases used for the electronic researches were PubMed, Scopus, Lilacs/BBO, Web of Science, and Cochrane Library. Grey literature was reviewed through Open Grey literature with no language or date restrictions. Selection criteria, based on the PECO strategy, were considered eligible observational studies that included schoolchildren or adolescents (P) with malocclusion (E), compared to those with normal occlusion (C), in which the relationship between malocclusion and bullying was determined (O).
DATA COLLECTION AND ANALYSIS
Risk of bias evaluation was made for the qualitative synthesis by the Fowkes and Fulton criteria. Data regarding the age of participants and types of malocclusion and of bullying were extracted among other reported data. The quality of the evidence analyzed was evaluated through the GRADE approach.
RESULTS
From 2744 articles identified in databases, nine met the eligibility criteria and were included in present systematic review, of which two studies were judged with methodological soundness. The quality of the evidence was classified as very low due to very serious problems for "risk of bias" and "other considerations" and serious problems of "indirectness". The age of participants ranged from 9 to 34 years considering a cohort study, with a bullying recalling perspective. Malocclusion was both evaluated by researchers and self-reported by participants addressing dentofacial characteristics mostly related to the incisors relationship. All studies evaluated the verbal type of bullying, while 3 also considered physical type. Both types were reported as related to malocclusion, although the results showed that extreme maxillary overjet (> 4 mm, > 6 mm, > 9 mm), extreme deep overbite, and having space between anterior teeth or missing teeth were the types of malocclusion with the strongest relations to bullying.
CONCLUSIONS
With very low certainty of evidence, the results of this systematic review suggest that conspicuous extreme malocclusion may be related to the occurrence of bullying among children and adolescents.

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.

Meta-Analysis
BACKGROUND/AIMS
Traumatic dental injuries are one of the most prevalent diseases globally, impacting people of different ages and socio-economic statuses. As disease prevention is preferable to management, understanding when an individual's overjet is prone to dental trauma helps identify at-risk patients, so to institute preventive strategies. The aim of this study was to identify the different overjet sizes that present an increased risk for developing dental trauma across different ages and dentition stages.
METHODS
The title and protocol were registered and published a priori with the Joanna Briggs Institute (JBI) and PROSPERO (CRD42017060907) and followed the JBI methodology of systematic reviews of association (etiology). A three-step search strategy was performed, including electronic searches of gray literature and four databases. Studies of healthy human participants of any age and in any dental dentition stage were considered for inclusion. Only high methodological quality studies with low risk of bias were included. Where possible, meta-analyses were performed using the random-effects model, supplemented with the fixed-effects model in situations where statistical heterogeneity was ≤50%, assessed using the I statistic.
RESULTS
The study identified 3718 articles, 41 were included. An increased overjet was significantly associated with higher odds of developing trauma in all dentition stages and age groups. Children 0-6 years with an overjet ≥3mm have an odds of 3.37 (95%CI, 1.36-8.38, P = 0.009) for trauma. Children in the mixed and secondary dentition with an overjet >5mm have an odds of 2.43 (95%CI, 1.34-4.42, P = 0.004). Twelve-year-old children with an overjet >5mm have an odds of 1.81 (95%CI, 1.44-2.27, P < 0.0001).
CONCLUSIONS
The results confirm the association between increased overjet and dental trauma. A child in the primary dentition could be considered as having an overjet at risk for trauma when it is ≥3mm. In the early secondary dentition, the threshold for trauma is an overjet ≥5mm.

BACKGROUND
Long-term dental stability is one of the main objectives following combined orthodontic and orthognathic surgical treatment. It is influenced by multiple factors such as surgical, patient-related, and orthodontic aspects. While recent reviews mainly focus on short-term dental changes (0.5-2 years), longer follow-up dental stability remains hardly reviewed.
OBJECTIVES
The aim of this study was to evaluate long-term stability of dental and dentolabial changes following combined orthodontic and orthognathic surgical treatment with a minimum follow-up period of 5 years.
SEARCH METHODS
A systematic search was conducted up to December 2019 using Pubmed, Embase, Web of Science, and Cochrane Central.
SELECTION CRITERIA
Randomized controlled trials (RCTs), prospective and retrospective cohort studies, and case series with a minimum of 10 patients, which reported long-term dental stability following combined orthodontic and orthognathic treatment, were included.
DATA COLLECTION AND ANALYSIS
Long-term changes were assessed for overjet, overbite, maxillary, and mandibular incisors' position and relationship of lip position to maxillary and mandibular incisors. Risk of bias was assessed according to the Cochrane Handbook.
RESULTS
Following the screening of 3178 articles, 11 studies were included (2 RCT, 9 retrospective) with a postoperative follow-up period ranging from 5 to 15 years. A decrease in overjet was observed for patients with skeletal class III malocclusion, whereas overjet increased in class II patients at long-term follow-up. Overbite increased in class II patients, whereas class III showed variable results. The lower incisor position was more stable vertically than horizontally; the latter showing more outcome variability. Dentolabial changes corresponded to the normal ageing process and results were not clinically significant after long-term follow-up.
CONCLUSION
Current evidence suggests variability of dental and dentolabial stability in both skeletal class II and III patients. Further prospective studies are required to develop guidelines for long-term follow-up assessment using computer tomography or cone-beam computed tomography imaging, before final conclusions can be drawn.
REGISTRATION
The protocol for this systematic review (CRD42020133844) was registered in the International Prospective Register of Systematic Reviews (PROSPERO).

Review
BACKGROUND
Mandibular advancement devices for obstructive sleep apnea treatment are becoming increasingly popular among patients who do not prefer CPAP devices or surgery. Our study aims to evaluate the literature regarding potential dental and skeletal side effects caused by mandibular advancement appliances used for adult OSA treatment.
METHODS
Electronic databases were searched for published and unpublished literature along with the reference lists of the eligible studies. Randomized clinical trials and non-randomized trials assessing dental and skeletal changes by comparing cephalometric radiographs were selected. Study selection, data extraction, and risk of bias assessment were performed individually and in duplicate. Fourteen articles were finally selected (two randomized clinical trials and 12 non-randomized trials).
RESULTS
The results suggest that mandibular advancement devices used for OSA treatment increase the lower incisor proclination by 1.54 ± 0.16°, decrease overjet by 0.89 ± 0.04 mm and overbite by 0.68 ± 0.04 mm, rotate the mandible downward and forward, and increase the SNA angle by to 0.06 ± 0.03°. The meta-analysis revealed high statistical heterogeneity.
CONCLUSIONS
The MADs affect the lower incisor proclination, overjet, overbite, the rotation of the mandible and the SNA angle. More randomized clinical trials providing high-quality evidence are needed to support those findings.

Meta-Analysis Review
BACKGROUND/AIM
Dental trauma (DT) occurs frequently in children and adolescents. Therefore, understanding the factors associated with its occurrence in these age groups is important to establish specific preventive measures. The aim of this study was to investigate the relationships of lip coverage, overjet, and open bite to dental trauma in Brazilian children and adolescents.
MATERIAL AND METHODS
The review protocol was registered in the PROSPERO database (CRD42020156290) and the bibliographic search was performed in nine electronic databases until July 2020. The studies included were observational, performed in Brazil, with healthy children and adolescents (0-19 years old), and without the restriction of date or language. Two reviewers assessed the individual risk of bias of the eligible studies with a standardized checklist. The meta-analyses were stratified by dentition stage and age range using fixed or random effects, odds ratio (OR) as the effect measure, and 95% confidence interval. The heterogeneity across studies was assessed with the I² test and the GRADE approach assessed the certainty of evidence.
RESULTS
The search presented 2493 initial results, from which 55 met the eligibility criteria and were included. Most studies (67%) presented a low risk of bias and were published between 2000 and 2019. Children and adolescents with inadequate lip coverage are 1.86-2.36 times more likely to suffer from DT, while those with increased overjet are 1.94-3.11 times more likely. Children with primary dentitions and anterior open bites are 1.76 (95% CI: 1.20-2.59) times more likely to suffer from DT. The certainty of evidence varied from very low to moderate.
CONCLUSIONS
Inadequate lip coverage, increased overjet, and anterior open bite are associated with the occurrence of dental trauma in Brazilian children and adolescents.

Review
The current review aims to evaluate the scientific evidence relating to the effectiveness of treatment with clear aligners (CAs) in controlling distalization orthodontic tooth movement. "Orthodontics, aligners" and "distalization" were the search terms used on the Scopus, Web of Science and Pubmed databases with the Boolean operator "AND". The results of the last ten years of research were 146 studies; of these, 19 publications were included for this review. The distalization movement is possible with invisible masks alone, but the risk of losing anchorage in the anterior sectors is very probable. The stability of the results and the reduction of unwanted effects can be guaranteed by the use of skeletal anchoring devices and interproximal enamel reduction (IPR), with which compensations are obtained to reduce the initial overjet. Temporary anchorage devices (TADs) can be used to manage posterior anchorage after distalization of maxillary molars with aligners. This hybrid approach has demonstrated the greatest orthodontic success. TADs are useful aids to provide direct and indirect skeletal anchorage. The opposite effect must be considered when planning dental distalization, especially of the molars, in patients with large overjet, and corrective measures or the use of auxiliaries may be necessary to prevent midcourse corrections. This systematic review provides a critical evidence-based assessment of the predictability of dental distalization with CAs, an ever-evolving orthodontic technique.

Review
OBJECTIVES
The aim of this article is to establish a comprehensive nation-wide prevalence of malocclusion traits on the sagittal, vertical, and transverse planes of space in Saudi Arabia.
MATERIALS AND METHODS
A systematic search was conducted in three databases (Medline via PubMed, Embase, and Web of Science) and complemented with a manual search of Google Scholar and the reference list of included studies. Original studies of Saudi Arabian healthy individuals at any age were included. The quality and the risk of bias of the included studies were assessed using the Joanna Briggs Institute's appraisal tool. The data about the selected malocclusion traits on the sagittal, vertical, and transverse planes of space were extracted and pooled.
RESULTS
Out of 7163 identified titles, 11 studies were finally included. The risk of bias was high in two studies, moderate in eight studies, and low in one study. The studied age groups were from early childhood to late adulthood, with a total sample size of 19,169 participants. The majority of the studies recruited their sample from school/public sources, whereas the remaining three studies recruited their sample from dental (non-orthodontic) clinics.
CONCLUSIONS
Within the limitations of this study, pooled prevalence of Angle's Class I molar relation in Saudi Arabia was similar to other populations but Angle's Class II and Class III molar relations were lower and higher, respectively. These differences could be attributed to population-related differences in craniofacial morphology. Teeth crowding, teeth spacing, and midline shift, along with increased overjet and overbite, were among the most common malocclusion traits occurring in Saudi Arabia.
