Meta-Analysis Review
OBJECTIVE
This review assessed the impact of oral conditions on Oral Health Related Quality of Life among Indians.
METHODS
Databases, including PubMed and Scopus, CINAHL, Web of Science, PsycInfo were systematically searched for English Language studies conducted among Indians up to July 2022. Two independent reviewers assessed studies selected for retrieval for methodological quality using standardised quality assessment instruments for analytical cross-sectional studies in JBI SUMARI.
RESULTS
Fourty one publications were included in this review (N = 23,090). Studies includes both cross sectional study and Randomized Controlled Trials. Based on the JBI critical appraisal tools, the quality of the included studies was low to high. Twenty-six studies were considered for the meta-analysis. Individuals with dental caries [OR: 3.54 (95% CI 2.24- 5.60), ten studies, 4945 participants] and malocclusion [ OR: 5.44 (95% CI 1.61, 18.39), six studies, 3720 participants] had poor OHRQoL compared to individuals without oral conditions.
CONCLUSIONS
Despite the various definitions of the exposures and instruments used to assess Oral Health-Related Quality of Life, our review found that people with dental caries and malocclusion have a significantly higher experience of poor quality of life.

Review
The literature on the impact of temporomandibular disorders (TMDs) on orthodontic management or vice versa lacks clarity. This study presents a review that aims to evaluate the influence of TMDs on orthodontic management and explore the association between TMDs and various aspects of orthodontic treatment. A systematic search was conducted across multiple databases to identify relevant articles documenting the correlation between TMD incidence and orthodontic treatment to achieve the objectives. The selection process followed predefined criteria, and the selected studies underwent bias assessment using the AXIS tool and Cochrane risk of bias (RoB) tool. Among the articles identified, nine studies were deemed suitable for inclusion in the review. The findings from the subsequent meta-analysis indicated a significant overall effect, suggesting that orthodontic treatment may increase the risk of developing TMD. Furthermore, the analysis revealed that patients with TMD had higher odds of experiencing orthodontic issues than those without TMD. Subgroup analysis further demonstrated that orthodontic treatment could have a negative impact on the psychological well-being of TMD patients, while its effect on TMD incidence was found to be negligible. The results highlight the need for additional research to gain a better understanding of the underlying mechanisms and develop appropriate interventions aimed at minimizing the risk of TMD in patients undergoing orthodontic treatment. Clinicians should be aware of TMD as a potential complication of orthodontic treatment and implement appropriate monitoring strategies.

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
OBJECTIVES
To evaluate the effects of a Twin-block appliance on the condyles of patients with ClassⅡmalocclusion by conducting a systematic review and a Meta-analysis.
METHODS
Pubmed, Embase, Cochrane Library, Chinese BioMedical Literature Database, China National Knowledge Infrastructure, and VIP Database were electronically searched. Randomized controlled trials, controlled clinical trials, and single-arm trials on condylar changes produced by a Twin-block appliance in patients with ClassⅡmalocclusion were included. Two reviewers independently extracted and assessed the risk of bias. Meta-analyses were conducted with Review Manager 5.3.
RESULTS
Eight studies were included; among which, seven were of high quality. After treatment with a twin block appliance, condyles moved anteriorly. The anterior joint spaces decreased (<0.000 01), whereas the posterior spaces increased (<0.000 01). The superior spaces were not changed (=0.11). Moreover, a significant difference was observed in the increase of the condylar space index (<0.000 01). After treatment, the anteroposterior diameters of the condyles and condylar height increased (=0.000 2 and <0.000 01, respectively). By contrast, no significant changes were discovered in the medial external diameters of the condyles (=0.42).
CONCLUSIONS
A Twin-block appliance can promote the growth of a condyle in the posterior and upper direction and move it forward in favor of the correction of Class Ⅱ malocclusion.

European Journal of Orthodontics Sep 2023The application of orthodontic forces causes root resorption of variable severity with potentially severe clinical ramifications.
BACKGROUND
The application of orthodontic forces causes root resorption of variable severity with potentially severe clinical ramifications.
OBJECTIVE
To systematically review reports on the pathophysiological mechanisms of orthodontically induced inflammatory root resorption (OIIRR) and the associated risk factors based on in vitro, experimental, and in vivo studies.
SEARCH METHODS
We undertook an electronic search of four databases and a separate hand-search.
SELECTION CRITERIA
Studies reporting on the effect of orthodontic forces with/without the addition of potential risk factors on OIIRR, including (1) gene expression in in-vitro studies, the incidence root resorption in (2) animal studies, and (3) human studies.
DATA COLLECTION AND ANALYSIS
Potential hits underwent a two-step selection, data extraction, quality assessment, and systematic appraisal performed by duplicate examiners.
RESULTS
One hundred and eighteen articles met the eligibility criteria. Studies varied considerably in methodology, reporting of results, and variable risk of bias judgements.In summary, the variable evidence identified supports the notion that the application of orthodontic forces leads to (1) characteristic alterations of molecular expression profiles in vitro, (2) an increased rate of OIIRR in animal models, as well as (3) in human studies. Importantly, the additional presence of risk factors such as malocclusion, previous trauma, and medications like corticosteroids increased the severity of OIIRR, whilst other factors decreased its severity, including oral contraceptives, baicalin, and high caffeine.
CONCLUSIONS
Based on the systematically reviewed evidence, OIIRR seems to be an inevitable consequence of the application of orthodontic forces-with different risk factors modifying its severity. Our review has identified several molecular mechanisms that can help explain this link between orthodontic forces and OIIRR. Nevertheless, it must be noted that the available eligible literature was in part significantly confounded by bias and was characterized by substantial methodological heterogeneity, suggesting that the results of this systematic review should be interpreted with caution.

European Archives of Paediatric... Aug 2023This study aims to evaluate whether there is a correlation between otitis and dental malocclusions.
PURPOSE
This study aims to evaluate whether there is a correlation between otitis and dental malocclusions.
METHODS
Electronic databases were searched for observational studies published until July 2021 without language or time restrictions.
PROSPERO
CRD42021270760. Observational studies on children with and without OM and/or malocclusion were included. After removing duplicates and excluding not-eligible articles, two reviewers screened relevant articles independently. Two reviewers independently extracted data and assessed data quality and validity through the Newcastle-Ottawa Scale (NOS) quality assessment tool for non-randomized studies.
RESULTS
Five studies met the selection inclusion criteria and were included in the studies for a total of 499 patients. Three studies investigated the relationship between malocclusion and otitis media, while the remaining two studies analyzed the inverse relationship and one of them considered eustachian tube dysfunction as a proxy of OM. An association between malocclusion and otitis media and vice versa emerged, although with relevant limitations.
CONCLUSION
There is some evidence that there is an association between otitis and malocclusion; however, it is not yet possible to establish a definitive correlation.

BACKGROUND
Early loss of second primary molars may lead to different malocclusions, mainly caused by the mesial migration of the first permanent molar. To prevent space loss in the dental arch, different types of space maintainers (SM) are used.
OBJECTIVES
The main objective of this systematic review is to examine the evidence in the literature regarding the effect of SM, including the clinical effect, risk of developing caries and periodontal disease, patient satisfaction, and cost-effectiveness after the premature loss of the second primary molar in children.
SEARCH METHODS
The present systematic review was made according to PRISMA. The literature search was performed using four databases (last search 30/8/2022): PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), Scopus, and Web of Science.
SELECTION CRITERIA
The studies included were randomized controlled trials, economic evaluations, and non-randomized clinical studies with a defined control group.
DATA COLLECTION AND ANALYSIS
Data collected by the two authors were in regard to reports, studies, participants, research designs, and interventions. The assessment of the risk of bias was made using the ROBINSON-I tool.
RESULTS
The search yielded 1058 articles after the removal of duplicates. Two studies were included in the final review with a moderate risk of bias, and measured space changes in the dental arch and the periodontal status of patients treated with SM. The main results indicate that treatment with SM can preserve arch length, but also cause an increase in plaque accumulation and other periodontal parameters. However, there is an overall lack of scientific evidence regarding the effect of the treatment.
LIMITATIONS
No studies that fulfilled the eligibility criteria were found on cost-effectiveness, risk of caries development, and patient satisfaction.
CONCLUSIONS
The scientific evidence is lacking regarding the clinical effect, cost effect, and side-effects such as caries and periodontal disease when using SM in children with a premature loss of the second primary molar.
