Review
BACKGROUND
This review synthesizes the available evidence about the predisposition of individuals with asthma or allergies to orthodontically induced inflammatory root resorption (OIIRR) and possible factors related to root resorption that were investigated in the included studies, such as the type of malocclusion, duration of orthodontic treatment, and tooth units.
MATERIAL AND METHODS
Six electronic databases and partial gray literature were searched without date or language restrictions until September 2020. Prospective and retrospective observational cohort and case-control studies were included. The risk of bias (RoB) was assessed using the checklists from the Joanna Briggs Institute and the certainty of the evidence using the GRADE tool. To complement the case-control studies, the odds ratio (OR) of the individuals with allergies/asthma to develop root resorption was calculated.
RESULTS
Six studies were included. One study with low RoB, one with moderate, and one with high RoB stated that allergic patients did not report a greater chance of developing OIIRR (OR = 1.17 to 2.10, p = 0.1 to 1), while only one study with low RoB reported that individuals with allergies tend to develop root resorption (OR = 2.4, 95% CI = 1.08-5.37). Three studies with low RoB and one with moderate showed no significant association between asthma and OIIRR (OR = 1.05 to 3.42, p = 0.12 to 0.94). No association was identified between the type of malocclusion and the degree of OIIRR. Uniradicular dental units and a prolonged treatment time seem to be associated with an increased risk of resorption. The certainty of the evidence was considered low for both exposure factors.
CONCLUSION
Evidence with a low level of certainty indicates that individuals with allergies or asthma are not more predisposed to OIIRR. Uniradicular teeth and long-term orthodontic treatments are associated with a higher risk of OIIRR.

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.

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.

This study aimed to assess the potential association between perception malocclusion and school performance in children and adolescents. An electronic search was performed in ten databases. Based on the PECO acronym (Population, Exposition, Comparator, and Outcome), the eligibility criteria included observational studies that compared the school performance of children and adolescents with and without the perception of malocclusion. There were no restrictions on the language or year of publication. Two reviewers selected the studies, extracted the data, and assessed the risk of bias by using the Joanna Briggs Institute tool for cross-sectional studies. School performance was measured by analyzing student grades; levels of absenteeism; and child or adolescent self-perception and/or the perception of parents, guardians, close friends, and teachers regarding the impact of malocclusion on school performance. The data were described narratively/descriptively. The search resulted in 3,581 registers, of which eight were included in the qualitative synthesis. These studies were published between 2007 and 2021. Two studies concluded that there was no significant association between school performance and perception of malocclusion, five studies found that only some of the children with malocclusion had their school performance affected, and one study concluded that there was a significant association between perception of malocclusion and low school performance. Considering all variables and the very low certainty of evidence, the perception of malocclusion seems to negatively impact school performance when associated with external and subjective factors. Further studies using additional measurement standards are required.

Bioengineering (Basel, Switzerland) Sep 2023This review aimed to analyze the relapse in orthognathic surgery. (Review)
Review
BACKGROUND
This review aimed to analyze the relapse in orthognathic surgery.
METHODS
PubMed, Scopus, and Web of Science databases were used to find papers that matched our topic dating from 1 January 2012 up to November 2022. Inclusion criteria were (1) human studies, (2) open access studies, (3) studies concerning the correlation between orthognathic surgery and relapse. Exclusion criteria were: (1) in vitro or animal studies, (2) off-topic studies, (3) reviews, (4) other languages than English.
RESULTS
A total of 482 results were obtained resulting in 323 publications after duplicate removal (158). After screening and eligibility phases 247 records were excluded: 47 reviews, 5 in animals, 35 in vitro, 180 off-topic. The authors successfully retrieved the remaining 78 papers and evaluated their eligibility. A total of 14 studies from these were ultimately included in the review.
CONCLUSION
Using cephalometric examinations and digital study models, these studies reveal that the relapse after orthognathic surgery is an event that occurs in most of the cases. The limitation of our research is that most of the studies are retrospective and use small sample sizes. A future research goal should be to conduct long-term clinical trials with larger numbers of samples.

Review
OBJECTIVE
This systematic review evaluates the variation in molar bite force (MBF) with the type and severity of dental malocclusion in young adults with permanent dentition.
METHODS
We searched seven electronic databases until December 31, 2021, and identified 1898 articles, of which 22 full-texts were reviewed. Eight clinical studies with subjects having permanent dentition with various dental malocclusions and quantifying maximal bite force were included for the review. Newcastle Ottawa scale was used to assess the risk of bias and GRADE to study the certainty of evidence. Articles were evaluated for the primary outcome (variation of MBF in different malocclusion groups) and confounding factors affecting MBF.
RESULTS
All studies measured MBF in individuals with normal and malocclusion, with 2329 subjects having permanent dentition. A positive correlation of Class I normal occlusion with the bite force was seen compared to Class II and III malocclusion. Unilateral crossbite patients had lesser bite force. Six studies with 1023 males and 1175 females showed MBF more in males than females. In 3 studies (332 subjects), no significant difference for MBF between the right and left sides of the jaws was measured.
CONCLUSION
MBF decreases significantly with vertical and transverse craniofacial and dental discrepancy. Normal sagittal occlusion has more molar bite force than patients with different malocclusions. Also, MBF is more in males than females, and it increases with age.

Review
OBJECTIVE
The aim of this study is to evaluate corticotomies effects to accelerate or facilitate dental movements in different kind of orthodontic treatments.
DATA
This report followed the PRISMA Statement. A total of 9 articles were included in review.
SOURCES
Two reviewers performed a literature search up to December 2018 in four databases: PubMed, Web of Science, Scopus and SciELO.
STUDY SELECTION
Controlled clinical trials and randomized controlled clinical trials conducted in human patients and published during the last 10 years in English were eligible to be selected. The articles should give detailed information about the results and treatment parameters. There were no limitations established in terms of the type of malocclusion to be corrected or the type of orthodontic treatment performed.
RESULTS
The methodological quality and evidence of the selected studies was low. Most of the studies observed a statistically significant increase in the rate of dental movement, when performing alveolar corticotomies as coadjuvants of orthodontic treatment; either with the conventional technique or with piezocision. The effect of combining corticotomy with bone grafts was assessed.
CONCLUSIONS
High heterogeneity among studies made it difficult to draw clear conclusions. However, within the limitations of this review, the corticotomy procedures were able to statistically and clinically produce significant temporary decrease in orthodontic tooth movement rate. This technique does not seem to involve major complications compared to conventional orthodontic treatments.
CLINICAL RELEVANCE
The use of this technique can reduce treatment time and therefore the undesirable effects associated with prolonged treatments.

Review
The reasons for searching orthodontic treatment in pediatric/adolescent patients are multifactorial. The aim of this systematic review was to study the parental influence in this process. This study comprises a systematic review of the literature, based on the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes. We analyzed 41 articles related to the study hypothesis, 29 of which followed the general inclusion criteria, and 21 specific studied the parental influence in orthodontic treatment. The results demonstrated that dental aesthetics and facial appearance were the main triggering factors related to the search for orthodontic treatment. Pair influence also plays an important role. The perception of malocclusion and the motivation are factors that emphasize the importance of parents in this process. Parental support was identified as a positive factor in orthodontic success reported in most of the studies. Parental influence has a positive effect on orthodontic treatment and should be understood by clinicians as a central factor in achieving the desired treatment plans.

Review
The aim of this study was to evaluate the efficacy and efficiency of orthodontic treatment using clear aligner therapy (CAT). This efficiency was measured using the Peer Assessment Rating (PAR) index, the American Board of Orthodontics (ABO) index, or the similarity between the final ClinCheck and the final scanned models. A search was done electronically between 1998 and 2021 using the Cochrane Library, PubMed, and Google Scholar databases. Three reviewers individually rated the articles. The ROBINS tool and the Cochrane risk of bias tool were used to evaluate the quality of observational research and randomized controlled trials, respectively. The degree of certainty for each selected outcome was evaluated using the grading of recommendations assessment, development, and evaluation (GRADE) approach.Six studies with a total of 166 participants were considered after the full texts of 61 potential reports were reviewed. This research included in the review covered the period from 1998 to 2021 in retrospect. According to the current systematic review and meta-analysis, transparent aligners had a successful outcome. In mild to moderate cases, aligner treatment appears to have a significant advantage in terms of efficiency (treatment time); nonetheless, insufficient evidence of efficacy was observed based on multiple cross-sectional investigations. When compared to traditional brackets, clear aligners provided a more stable course of treatment.

Review
OBJECTIVES
To estimate the pooled prevalence estimates of the malocclusion among child and adolescent population of India.
CONTENTS
A comprehensive electronic search was carried to find studies related to assessing malocclusion in Indian children and adolescent population. Indices and classifications considered for pooled analysis were Dental Aesthetic Index, Index of Orthodontic Treatment Needs, Angles classification and terminal plane relationship of primary secondary molars. An eligibility criterion was prepared and quality assessment was done for all the eligible studies. Initial search produced 1090 titles. After removal of duplicates, 850 records were left for further screening. Eighty one articles were found eligible for full text reading. Finally 60 studies were included in this meta-analysis. Pooled prevalence was used to estimate overall effect, with 95% confidence intervals (CI). Statistical difference between the two genders was calculated using chi square test.
SUMMARY AND OUTLOOK
The high prevalence of malocclusion is a public health problem around the world. The current status of burden of malocclusion among Indian children and adolescents is not known. Results of this pooled analysis showed that prevalence of malocclusion among Indian children and adolescents has increased since the last national oral health survey. Prevalence of malocclusion ranged from 28.4% (CI 25.02, 31.9) to 66.7% (CI 50.7, 81.06) depending on the type of index or classification used for recording. Boys recorded higher cumulative prevalence than girls. These findings can be utilized by oral health policy makers to draft measures required for reducing this burden of malocclusion.
