Meta-Analysis
PURPOSE
To investigate the odds of developing open proximal contact (OPC) between implant-supported fixed prostheses and adjacent teeth compared with that between tooth-supported fixed prostheses and adjacent teeth.
MATERIALS AND METHODS
A search was conducted in the Ovid MEDLINE, Embase, and Web of Science databases for clinical studies on OPC developed with implant-supported prostheses or tooth-supported prostheses. A meta-analysis was performed using statistical software to estimate the odds of developing OPC with implant-supported prostheses compared with tooth-supported prostheses, with a 95% confidence interval (CI). The statistical significance was defined as P < .05.
RESULTS
The odds ratio (OR) of developing OPC with implant-supported prostheses was 2.46 compared with tooth-supported prostheses (95% CI [1.21 to 5.01]; P = .013]. However, the data were highly heterogenous (τ = 0.40, I = 95.67%). The total estimates of developing OPC were 41% (95% CI [30% to 54%]) with implant-supported prostheses and 22% (95% CI [18% to 26%]) with tooth-supported prostheses. OPC was more prevalent at the mesial side than at the distal side of implant-supported prostheses (OR = 2.38, 95% CI [0.94 to 6]; P = .066), whereas OPC was more prevalent at the distal side than at the mesial side of tooth-supported prostheses (OR = 1.94, 95% CI [1.09 to 3.45]; P = .024). There was no statistically significant difference in developing OPC with covariates of sex, age, arch, splinting of implants or adjacent teeth, region, and vitality of adjacent teeth, retention type, opposing dentition, occlusal force, parafunctional activities, and follow-up time. OPC was found to increase 9% per year with implant-supported prostheses (OR = 1.09). The estimate of interproximal gap next to implant-supported prostheses was 245.8 μm (95% CI [86.4 to 405.3 μm]).
CONCLUSION
Within the limitations of this systematic review and meta-analysis, the odds of developing OPC were significantly higher with implant-supported prostheses than with tooth-supported prostheses. However, the data were highly heterogenous, and thus, a well-designed randomized clinical study needs to be conducted to validate the results of this systematic review.

Review
BACKGROUND
Oral breathing, nasal obstruction and airway space reduction are usually reported as associated to allergic rhinitis. They have been linked to altered facial patterns and dento-skeletal changes. However, no firm correlation based on the evidence has been established. This systematic review has been undertaken to evaluate the available evidence between malocclusion and allergic rhinitis in pediatric patients.
METHODS
The research refers to Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) guidelines, databases (Medline, Cochrane Library, Pubmed, Embase and Google Scholar) were screened, the quality was evaluated through Quality Assessment of Diagnosfic Accuracy Studies (QUADAS-2).
RESULTS
The articles selected (6 out of initial 1782) were divided on the basis of the study design: two observational randomized study, three case-control study, one descriptive cross-sectional study, and one longitudinal study. A total of 2188 patients were considered. Different results were reported as related to allergic rhinitis ranging from a higher incidence of dental malocclusion, to an increase of palatal depth, and in posterior cross-bite about anterior open-bite and to longer faces and shorter maxillas.
CONCLUSIONS
Most of the studies selected found a rise in the prevalence of both malocclusion and allergic rhinitis in children. However, the level of bias is high, impaired by a poor design and no conclusive evidence can be drawn.

Oral Diseases Mar 2022To evaluate whether individuals with osteogenesis imperfecta (OI) are more affected by malocclusion than individuals without OI. (Meta-Analysis)
Meta-Analysis Review
OBJECTIVE
To evaluate whether individuals with osteogenesis imperfecta (OI) are more affected by malocclusion than individuals without OI.
MATERIALS AND METHODS
Searches in PubMed, Ovid, Web of Science, Scopus, Lilacs and gray literature were performed. Data extraction was conducted by two researchers. Risk of bias assessment employing the Newcastle-Ottawa Scale and meta-analysis were conducted. Results were provided with mean difference (MD), odds ratio (OR) and 95% confidence interval (CI). Strength of evidence was determined.
RESULTS
Six cross-sectional studies were included. In comparison with individuals without OI, the group with OI had 19.69-fold greater chance of exhibiting Angle Class III malocclusion (OR = 19.69, CI: 9.00-43.09) and presenting anterior crossbite greater (MD = 6.08, CI: 2.40-9.77). Individuals without OI had a significantly greater ANB angle (MD = 3.88, CI: 1.15-6.61) and SNA angle (MD = 2.11, CI: 0.24-3.98) in comparison with those with OI. No difference between groups was found for SNB (MD = -0.50, CI: -2.21 to 1.21) and open bite (MD = 0.98, CI: -0.29 to 2.25). Most studies included had moderate methodological quality. Strength of evidence was low or very low.
CONCLUSIONS
The occurrence of Angle Class III malocclusion and anterior crossbite was greater among individuals with OI compared to those without OI. These findings can assist stakeholders about the occlusal abnormalities affecting OI individuals.

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.

Meta-Analysis
OBJECTIVES
The aim of this systematic review and meta-analysis is to assess the degree of stability of anterior open bite (AOB) treatment performed through the molar intrusion supported with skeletal anchorage at least 1 year posttreatment.
METHODS
This study was registered in PROSPERO (CRD42016037513). A literature search was conducted to identify randomized (RCT) or non-randomized clinical trials based including those considering before and after design. Data sources were electronic databases including PubMed, Cochrane Library, Science Direct, Google Scholar, Scopus, Lilacs, OpenGrey, Web of Science, and ClinicalTrials.gov . The quality of evidence was assessed through the JBI tool and certainty of evidence was evaluated through the GRADE tool. Random effects meta-analysis was conducted when appropriate.
RESULTS
Six hundred twenty-four articles met the initial inclusion criteria. From these, only 6 remained. The mean posttreatment follow-up time was 2.5 years (SD = 1.04). The overbite showed a standardized mean relapse of - 1.23 mm (95% CI - 1.64, - 0.81, p < 0.0001). Maxillary and mandibular incisors presented a non-significant mean relapse, U1-PP - 0.04 mm (95% CI - 0.55, 0.48) and L1-MP - 0.10 mm (95% CI - 0.57, 0.37). Molar intrusion showed a relapse rate around 12% for the maxillary molars and a 27.2% for mandibular molars.
CONCLUSION
The stability of AOB through molar intrusion using TADs can be considered relatively similar to that reported to surgical approaches, since 10 to 30% of relapse occurs both in maxillary and mandibular molars. The level of certainty ranged between very low and low. RCTs reporting dropout during the follow-up are in dire need.

Meta-Analysis
AIMS
Aim of the present systematic review and meta-analysis is to investigate the oral health status of children with cerebral palsy and to compare it to that of healthy children.
METHODS AND RESULTS
An electronic search extended to October 2019 was conducted on PubMed, Scopus, Web of Science and Cochrane Library. Two independent reviewers selected publications using a two-stage process; data were extracted according to PRISMA statement. The Newcastle Ottawa Scale was used to evaluate the risk of bias in individual studies. After screening of the 5460 studies selected 20 publications were included in the systematic review, 15 underwent quantitative analysis. In the palsy population statistical analysis showed an OR = 1.45 (95% CI: 1.05-2.00) for dental caries in the primary dentition and OR = 1.87 (95% CI: 1.07-3.24) for the simplified oral hygiene index. The OR of Angle's Class II and anterior open bite were 3.27 (95% CI: 1.22-8.81) and 14.06 (95% CI: 6.26-31.62), respectively.
CONCLUSION
Children with cerebral palsy seem to present an increased risk of dental caries in the primary dentition, of Angle's Class II malocclusion, anterior open bite and a lower gingival status.

The global epidemic of Zika virus has been a major public health problem affecting pregnant women and their infants. Zika virus causes a viral disease transmitted to humans mainly by the infected mosquito bite. The infection is not severe in most cases; however, there is evidence that infection during pregnancy may be associated with fetal genetic abnormalities (including microcephaly). In addition to microcephaly and other malformations, some specific lesions in the central nervous system have been reported. The aim of this systematic review was to determine the risk of developing microcephaly in infants whose mothers were infected with Zika virus in pregnancy. Epidemiological studies and case reports were incorporated in our review, finally including 15 articles from an initial pool of 355 related papers. Most studies have linked maternal infection during pregnancy to the development of neonatal microcephaly. The period considered most dangerous is the first trimester and the beginning or the whole of the second trimester. In order to understand the relationship between Zika virus and microcephaly in infants, a cohort study will be able to estimate the time from the onset of Zika infection and the full spectrum of adverse pregnancy outcomes.

Meta-Analysis
BACKGROUND
Previous studies have shown a high prevalence of malocclusion in people with Down syndrome (DS) compared to individuals without DS, but no systematic review to summarize the evidence on this topic has been performed thus far.
AIM
To evaluate whether children/adolescents with DS are more affected by malocclusion than those without DS.
DESIGN
A search was performed in seven electronic databases. The quality of the included studies was assessed using the Newcastle-Ottawa Scale. The strength of the evidence from the selected studies was evaluated by the Grading of Recommendations Assessment, Development and Evaluation system.
RESULTS
Eleven publications were included in the systematic review and eight were meta-analysed. The meta-analysis showed that malocclusion was more prevalent in children/adolescents with DS for Angle Class III (risk difference [RD] = 0.40; confidence interval [CI] = 0.33, 0.46), posterior crossbite (risk ratio [RR] = 3.09; CI = 2.02, 4.73), anterior crossbite (RR = 2.18; CI = 1.41, 3.39), and anterior open bite (RD = 0.21; CI = 0.06, 0.36).
CONCLUSION
The occurrence of malocclusion was higher in children/adolescents with DS compared to individuals without the syndrome. The strength of the evidence of the studies analysed, however, was considered moderate and low.

OBJECTIVE
Considering that the available studies on prevalence of malocclusions are local or national-based, this study aimed to pool data to determine the distribution of malocclusion traits worldwide in mixed and permanent dentitions.
METHODS
An electronic search was conducted using PubMed, Embase and Google Scholar search engines, to retrieve data on malocclusion prevalence for both mixed and permanent dentitions, up to December 2016.
RESULTS
Out of 2,977 retrieved studies, 53 were included. In permanent dentition, the global distributions of Class I, Class II, and Class III malocclusion were 74.7% [31 - 97%], 19.56% [2 - 63%] and 5.93% [1 - 20%], respectively. In mixed dentition, the distributions of these malocclusions were 73% [40 - 96%], 23% [2 - 58%] and 4% [0.7 - 13%]. Regarding vertical malocclusions, the observed deep overbite and open bite were 21.98% and 4.93%, respectively. Posterior crossbite affected 9.39% of the sample. Africans showed the highest prevalence of Class I and open bite in permanent dentition (89% and 8%, respectively), and in mixed dentition (93% and 10%, respectively), while Caucasians showed the highest prevalence of Class II in permanent dentition (23%) and mixed dentition (26%). Class III malocclusion in mixed dentition was highly prevalent among Mongoloids.
CONCLUSION
Worldwide, in mixed and permanent dentitions, Angle Class I malocclusion is more prevalent than Class II, specifically among Africans; the least prevalent was Class III, although higher among Mongoloids in mixed dentition. In vertical dimension, open bite was highest among Mongoloids in mixed dentition. Posterior crossbite was more prevalent in permanent dentition in Europe.

Meta-Analysis
Effect of orthodontic management and orofacial muscle training protocols on the correction of myofunctional and myoskeletal problems in developing dentition. A systematic review and meta-analysis.
The aim of this review was to evaluate available evidence on the effect of early orthodontic management and myofunctional treatment in the developing dentition children, on anterior open bite correction, as well as on normalization of patterns of mouth breathing, swallowing and tongue resting position and pressure. Electronic searches in MEDLINE, Cochrane and LILACS, without language restrictions were conducted. Additionally, unpublished literature was identified. Randomized controlled trials, or controlled clinical trials, comparing interventions applied to manage anterior open bite and other muscle functions such as breathing/swallowing pattern and tongue resting position and pressure, were considered. Quality assessment was based on the Cochrane Risk of Bias tool. Random effects meta-analyses were conducted to assess treatment effects. From the 265 initial search results, 15 articles were included in the review. Eight were randomized controlled trials (RCTs) and 7 were controlled clinical trials. Treatment outcomes comprised skeletal and dentoalveolar changes recorded cephalometrically, mouth posture and lip closure normalization, improvement of tongue resting position/pressure and modification of swallowing pattern. Quantitative synthesis was possible for only 2 of the included RCTs. There was no evidence to support bonded lingual spurs over banded fixed appliances for the correction of anterior open bite in mixed dentition children presenting nonnutritive oral habits at the onset of treatment (SMD: -0.03; 95%CI: -.81, 0.74; P = 0.94). Although early orthodontic management and myofunctional treatment in the deciduous and mixed dentition children appears to be a promising approach, the quality of the existing evidence is questionable.
