Risk of Bias and Methodological Critical Appraisal in Systematic Reviews of Non- and Micro-Invasive Caries Management for Primary and Permanent Teeth.

INTRODUCTION: Pediatric dentistry should rely on evidence-based clinical decisions supported by high-quality, unbiased systematic reviews (SRs). Therefore, the purpose of this study was to systematically evaluate the methodological quality and risk of bias of SRs focused on non- and micro-invasive treatment for caries lesions in primary and permanent teeth. METHODS: A comprehensive search was conducted in multiple databases, including MEDLINE/PubMed, Scopus, Web of Science, EMBASE, Epistemonikos, and ProQuest, up to March 2023 to identify relevant systematic reviews (SRs) focused on non- and micro-invasive caries treatment. Two independent reviewers extracted data from the included SRs and assessed the methodological quality and risk of bias using the AMSTAR 2 and ROBIS tools, respectively. RESULTS: A total of 39 SRs were included in the analysis. Among these, 27 SRs (69.2%) were assessed as having critically low methodological quality, 11 SRs (28.2%) were considered to have low methodological quality, and only one SR was rated as high-quality. The primary concern identified was the absence of protocol registration before commencing of the study, observed in 33 SR when using the AMSTAR 2 tool. According to the ROBIS tool, 21 studies (53.8%) were categorized as low risk of bias, 10 (25.6%) as high risk, and eight (20.5%) as unclear risk of bias. CONCLUSION: Our analysis revealed that SRs focused on non- and micro-invasive treatment for caries in children and adolescents had critically low methodological quality according to the AMSTAR 2 tool but demonstrated a low risk of bias based on the ROBIS tool. These findings highlight the importance of emphasizing prospective protocol registration, transparent reporting of statistical analyses, and addressing potential bias implications within this topic. By addressing these issues, we can enhance the quality of SRs and ensure that clinical decisions rely on unbiased and trustworthy evidence.

CONSORT statement adherence and risk of bias in randomized controlled trials on deep caries management: a meta-research.

BACKGROUND: Recently, trials have supported changes in deep caries management. However, reporting might lack details, affecting interpretation and implementation. Thus, we aimed to evaluate the adherence to the CONSORT statement and the risk of bias of randomized controlled trials (RCTs) on deep caries management published in pediatric dental journals. METHODS: We searched PubMed for RCTs in six pediatric dental journals between 2010 and 2022, focusing on deep caries lesion management. Adherence to the CONSORT guideline and the risk of bias were assessed using a modified tool with 19 items; each scored from 0 to 2 (maximum of 38 points), and the Cochrane risk-of-bias (RoB 2) tool. We performed descriptive and regression analyses (α = 5%). RESULTS: We analyzed 127 RCTs. The mean (standard deviation) CONSORT adherence score was 21.1 (6.7). Notably, 96.1% of the studies received a score of 2 for the "intervention" item, whereas 83.5% scored 0 for the "estimated effect size". The risk of bias assessment revealed that 40.2% of the RCTs were at high risk, 59% were at low risk, and 0.8% were at low risk. RCTs with a high risk of bias had lower CONSORT scores (p<0.001) than those with low or some concerns. RCTs published in journals without the endorsement of the CONSORT statement had lower scores than those in journals with the endorsement of the CONSORT statement. Older RCTs (6-10 years old and more than 10 years old) showed significantly lower CONSORT statement compliance than trials published recently within 5 years. CONCLUSION: Adherence to the CONSORT was relatively low among the investigated RCTs. Moreover, lower adherence to the CONSORT was associated with a higher risk of bias. TRIAL REGISTRATION: This study protocol was prospectively registered on the Open Science Framework - DOI ( 10.17605/OSF.IO/V6SYZ ).

Standardization of Dental Vulnerability Scale scores (EVO-BR).

BACKGROUND: Dental Vulnerability Scale (EVO-BR) is an instrument developed to help identifying oral health-vulnerable individuals. This scale comprises 15 items distributed into 4 dimensions. It is the first instrument with the potential to guide clinical and managerial decisions in the oral health field. The aim is to validate a score to enable using EVO-BR in Primary Health Care (PHC). METHOD: The investigated sample included PHC users in five Brazilian regions. Data were collected at two different stages: in 2019 (São Paulo) and in 2022 (Minas Gerais, Mato Grosso, Roraima, Pernambuco e Paraná). Exploratory descriptive study of this scale scores was carried out to create classification ranges. Subsequently, discriminant analysis was performed to assess the accuracy of the established classification. Boosting regression was carried out to check items' weight for the instrument score. RESULTS: EVO-BR score ranged from 0 (highest vulnerability) to 15 (lowest vulnerability). Four (4) classification configurations were tested. Score equal to 12 points was the one presenting the best classification of the assessed individuals (100% were correctly classified). Boosting regression has evidenced that items 1 and 2 (Overall health domain) and 14 and 15 (Health Services domain) had the strongest influence on this instrument's score. CONCLUSION: The process to standardize the EVO-BR score and, consequently, to develop assessment ranges, is an important step in the fight against health inequalities, since it provides a tool to help planning actions and interventions aimed at meeting specific needs of the population in the Primary Health Care context.

How different attributes are weighted in professionals' decision-making in Pediatric Dentistry-a protocol for guiding discrete choice experiment focused on shortening the evidence-based practice implementation for dental care.

BACKGROUND: Important evidence has been constantly produced and needs to be converted into practice. Professional consumption of such evidence may be a barrier to its implementation. Then, effective implementation of evidence-based interventions in clinical practice leans on the understanding of how professionals value attributes when choosing between options for dental care, permitting to guide this implementation process by maximizing strengthens and minimizing barriers related to that. METHODS: This is part of a broader project investigating the potential of incorporating scientific evidence into clinical practice and public policy recommendations and guidelines, identifying strengths and barriers in such an implementation process. The present research protocol comprises a Discrete Choice Experiment (DCE) from the Brazilian oral health professionals' perspective, aiming to assess how different factors are associated with professional decision-making in dental care, including the role of scientific evidence. Different choice sets will be developed, either focusing on understanding the role of scientific evidence in the professional decision-making process or on understanding specific attributes associated with different interventions recently tested in randomized clinical trials and available as newly produced scientific evidence to be used in clinical practice. DISCUSSION: Translating research into practice usually requires time and effort. Shortening this process may be useful for faster incorporation into clinical practice and beneficial to the population. Understanding the context and professionals' decision-making preferences is crucial to designing more effective implementation and/or educational initiatives. Ultimately, we expect to design an efficient implementation strategy that overcomes threats and potential opportunities identified during the DCEs, creating a customized structure for dental professionals.

Selective outcome reporting in paediatric dentistry restorative treatment randomised clinical trials-A meta-research.

BACKGROUND: Selective outcome reporting (SOR) is a bias that occurs when the primary outcome of a randomised clinical trial (RCT) is omitted or changed. AIM: To evaluate the prevalence of SOR in RCTs on restorative treatment in primary teeth. DESIGN: We conducted an electronic search on ClinicalTrials.gov and the World Health Organization platform (International Clinical Trials Registry Platform) on 1st of April 2021, with no registry time or language restrictions. We included RCT protocols that evaluated restorative treatments in primary teeth and excluded trials that did not have a complete publication in a scientific journal. The chi-squared test was used to identify the association between SOR and variables as a discrepancy in the follow-up period, the timing of registration, the type of sponsorship and the type of study design (α = 5%). RESULTS: Of the 294 identified protocols, 30 were included in the study. 83.3% of trials were registered retrospectively. SOR was observed in 53.3% (n = 16) of the published trials and was significantly associated with a discrepancy in the follow-up period (p = .017). CONCLUSIONS: The high prevalence of SOR in RCTs on restorative treatment proves that this is a prominent threat. A proper preregistered protocol, declaration of any protocol deviation and allowance of stakeholders to compare the protocol with that of the submitted papers will achieve transparency.

Do the clinical practice guidelines for paediatric dentistry meet the quality standards? A meta-research and quality appraisal using the AGREE II tool.

BACKGROUND: Clinical practice guidelines (CPGs) enhance health care and aid clinicians' decisions. AIM: To evaluate the quality of clinical guidelines in paediatric dentistry using the AGREE II tool. DESIGN: PubMed, EMBASE, Scopus, LIVIVO, Lilacs, international guidelines websites, scientific societies, and gray literature were searched until September 2021. We included paediatric dental clinical guidelines and excluded drafts or guidelines for patients with special needs. Two independent reviewers performed quality assessment using the APPRAISAL OF GUIDELINES FOR RESEARCH & EVALUATION II (AGREE II) instrument. We calculated the mean overall domain scores (95% confidence interval) for each guideline. We used regression analysis to correlate the score of overall assessment and the six domains of AGREE II with guideline characteristics. RESULTS: Forty-four guidelines were included in this study. Highest mean score was for Domain 4 (Clarity of Presentation; 58%, 95% CI: 50.8-64.9), whereas the lowest was for Domain 5 (Applicability; 16%, 95% CI: 10.8-21.4). The reporting quality was improved in Domains 1-5 with reporting checklists (p < .001), whereas that of Domain 6 was improved by decreasing years since publication (p = .047). CONCLUSION: Paediatric dental guidelines do not comply with the methodological quality standard, especially in Domain 5 (Applicability). The AGREE reporting checklist should be implemented with a system to evaluate the certainty of evidence for future guidelines.

Clinical Accuracy of Two Different Criteria for the Detection of Caries Lesions around Restorations in Primary Teeth.

This is a delayed-type cross-sectional prospective accuracy study nested in a randomized clinical trial. The aim was to investigate the diagnostic accuracy of two visual criteria for caries lesions detection around restorations in primary teeth: the International Dental Federation (FDI) criteria, considering adaptation, staining, and the presence of caries, and the Caries Associated with Restorations and Sealants (CARS) system. For this, one examiner made the diagnosis and subsequent treatment decision using visual assessment in 163 children (3-10 years old) with both FDI and CARS criteria. The order of criteria used was defined by randomization. The reference standard was composed of two approaches: (1) the presence of carious tissue after restoration removal and (2) the presence of caries lesions after 6 and 12 months of follow-up. Sensitivity, specificity, and accuracy parameters were calculated at the dentin threshold. Poisson multilevel regression analyses were performed to evaluate the association of the diagnostic methods and other explanatory variables with the outcomes. Of the 651 restorations included, 480 were evaluated by the reference standard methods and were analyzed. The CARS system presented higher accuracy (0.721) than those obtained with FDI recurrence of caries (0.702), FDI marginal adaptation (0.700), and FDI marginal staining criteria (0.681). The FDI marginal staining showed the study's lowest sensitivity (0.280) and accuracy (0.681) values. The specificity values of FDI recurrence of caries and FDI marginal adaptation were lower than the CARS system. Restorations assessed after the follow-up period resulted in lower sensitivity but higher specificity than those replaced after initial evaluation. In conclusion, the CARS system is more accurate in detecting caries around restorations in primary teeth than the FDI system, in general. However, the FDI recurrence of caries and FDI marginal adaptation present similar performance to the CARS system when the dentin threshold is considered. On the other hand, marginal staining is not an accurate parameter to evaluate caries around restorations.

Nonrestorative treatment of initial caries lesion in primary teeth: a systematic review and network meta-analysis.

OBJECTIVE: To identify the best available approach to avoid initial caries lesions progression in primary teeth. MATERIALS AND METHODS: Search was performed in MEDLINE/Pubmed, Web of Science, Embase and CENTRAL databases until March 2021. Studies compared treatment options to avoid the initial caries lesion progression with at least 12 months of follow-up were included. Network meta-analyses were conducted considering the non-progression of caries lesions as an outcome. RESULTS: Potentially eligible studies were screened (n = 2820) and eleven were included. Six studies evaluated the use of fluoride varnish, resin infiltration, sealing, and toothbrushing/flossing on proximal initial caries lesions. When considering occlusal surfaces, only two studies evaluating the ozone gas, fluoride varnish, resin infiltration, and sealants were included. For buccal/lingual surfaces, three studies evaluating toothbrushing, CPP-ACP paste, fluoride varnish, and resin infiltration were included. For all types of surfaces, the resin infiltration showed the best probability to avoid the progression of initial caries lesions. CONCLUSION: The limited number of included studies, most with a high risk of bias and lack of hard outcomes, such as frank cavitation, makes it not feasible to recommend a specific management approach for initial caries lesion control in primary teeth with a high certainty of evidence.

Impact of early childhood caries severity on oral health-related quality of life among preschool children in Mexico: A cross-sectional study.

BACKGROUND: Information is scarce on Early Childhood Caries (ECC) in Mexican preschool children and its impact on quality of life. AIM: To evaluate the ECC prevalence and its impact on OHRQoL in 3-5 years-old Mexican children according to disease severity. DESIGN: Caries was determined at two thresholds: (1) children with at least one caries lesion (ICDAS-1-6) and (2) children with at least one lesion in dentin (ICDAS-3-6). OHRQoL was assessed through the Mexican Early Childhood Oral Health Impact Scale (M-ECOHIS). Associations among caries severity, M-ECOHIS, and other variables were assessed by ordinal logistic regression. RESULTS: A total of 409 children participated (53.8% girls, 46.2% boys). Caries prevalence was 82.2% considering all lesions, and 45.0% for dentinal lesions. Significant linear trends (p < .05) among caries levels and categories of exposure were found for socioeconomic variables, dietary habits, and toothbrushing habits. Attending rural private schools (OR = 1.39, 95%CI = 1.11-1.72; p < .01), two main meals/day (OR = 2.75, 95%CI = 1.26-6.03; p = .01) and unsupervised toothbrushing (OR = 3.20, 95%CI = 1.96-5.24; p < .01) increased the risk to have high caries severity levels. M-ECOHIS scores were statistically significant associated with caries levels (χ2 (4)  = 175.85, p < .01; trend across groups z = 12.63 Prob > |z| < 0.01). CONCLUSIONS: M-ECOHIS was significantly associated with caries severity. Type of school, age groups, parents' educational level, family income, and living conditions were correlated with caries, showing how distinctive risk indicators were associated with different caries stages.

Botulinum Toxin A in the Management of a Gummy Smile: A Clinical Controlled Preliminary Study.

BACKGROUND: Botulinum toxin type A (BTX-A) is recent technique for the treatment of gummy smile. OBJECTIVES: The aim of this randomized controlled preliminary clinical trial was to evaluate the effects of BTX-A on excessive gingiva display (EGD) reduction, muscle activity, and patient satisfaction at 2, 8, 12, 16, 21, and 25 weeks. METHODS: Group 1 (G1) received 4 points of BTX-A application (2 U/point) for relaxation of the levator labii superioris alaeque nasi and levator labii superioris muscles; Group 2 (G2) received 2 points of BTX-A (2 U/point) for relaxation of only the levator labii superioris alaeque nasi muscle. RESULTS: A high dropout of patients from follow-up sessions occurred. Therefore, because of this data limitation, the results were considered a preliminary outcome. At 2 weeks, there was a significant difference between baseline regarding the reduction of EGD in G1 and G2, reduction in muscle activity in G1, and increased satisfaction in G1 and G2. At 2 weeks, there was no difference between the 2 groups. Statistically significant EGD reduction was maintained until 16 weeks in G2 and 25 weeks in G1. After 14 days there was a gradual recovery of muscle activity in both groups until recovery of baseline values by 25 weeks. Patients' satisfaction with treatment lasted 21 weeks in G1 and 16 weeks in G2. CONCLUSIONS: Increasing the number of BTX-A injection points resulted in a prolonged effect regarding EGD reduction and patient satisfaction but did not increase the intensity of the outcome. However, due to the high dropout of patients, this is a preliminary conclusion and further studies are necessary to confirm these results.

Guided Surgery with 3D Printed Device: A Case Report.

Dental surgeons need in-depth knowledge of the bone tissue status and gingival morphology of atrophic maxillae. The aim of this study is to describe preoperative virtual planning of placement of 5 implants and to compare the plan with the actual surgical results. Three-dimensional (3D) planning of rehabilitation using software programs enables surgical guides to be specially designed for the implant site and manufactured using 3D printing. A patient with 5 teeth missing was selected for this study. The patient's maxillary region was scanned with cone-beam computed tomography (CBCT), and a cast model was produced. After virtual planning using ImplantViewer, 5 implants were placed using a printed surgical guide. Two weeks after the surgical procedure, the patient underwent another CBCT scan of the maxilla. Statistically significant differences were detected between the virtually planned positions and the actual positions of the implants, with a mean deviation of 0.36 mm in the cervical region and 0.7 mm in the apical region. The surgical technique used enables more accurate procedures compared with the conventional technique. Implants can be better positioned, with a high level of predictability, reducing both operating time and patient discomfort.

Sedation versus protective stabilization for dental treatment of children with caries and challenging behavior at the dentist (CHOOSE): a study protocol for a non-randomized clinical trial.

BACKGROUND: There is a lack of evidence on the effectiveness of moderate sedation in pediatric dentistry, compared to protective stabilization, which remains routinely used in Brazil despite moral questions. This prospective non-randomized clinical trial's objective is to evaluate the effectiveness of moderate sedation, compared to the protective stabilization, in the dental care of children with dental behavior management problems. METHODS: Participants will be 152 children under seven years of age with early childhood caries (ECC) who need specialized dental treatment due to a history of challenging behavior during dental care. The interventions to be compared are moderate sedation with oral administration of ketamine and midazolam and protective stabilization. The primary endpoint will be the child's behavior during treatment assessed using the Ohio State University Behavioral Rating Scale (OSUBRS). The secondary outcomes are (A) child's - behavior according to the visual analogue scale, anxiety, pain, and physiological stress; (B) parent's - satisfaction and anxiety; (C) family and child - impact on oral health-related quality of life (OHRQoL); (D) dentist's - satisfaction and stress; (E) procedure - adverse events of the intervention and dental treatment longevity. A cost-effectiveness analysis will be performed from the perspective of the Brazilian Unified Health System (SUS). DISCUSSION: Considering the primary outcome, this study hypothesis is that sedated children have better behavior during dental treatment than children whose behavior was managed by protective stabilization without sedation. Additionally, at the end of 12 months, we expect to identify participants' reported outcomes and objective measures related to dental behavior in early childhood.

Survival rate of primary molar restorations is not influenced by hand mixed or encapsulated GIC: 24 months RCT.

BACKGROUND: Glass ionomer cements (GIC) have been considered the top option to restore primary teeth by dentists. The most common supply forms are hand mixed and encapsulated GIC. There is a lack of information about the impact of different GIC supply forms on restoration survival. METHODS: This randomized clinical trial compared the survival rate of occlusal and occlusoproximal restorations in primary molars using two glass ionomer cements versions: hand-mixed (H/M) and encapsulated (ENC) after 24 months. Children aged 3-10 years who presented dentin caries lesions in primary molars were selected at School of Dentistry, University of São Paulo, Brazil. They were randomly assigned to groups: H /M (Fuji IX®, GC Europe) or ENC (Equia Fill®, GC Europe). The occurrence of restoration failure was evaluated by two blinded and calibrated examiners. The analyses were performed in Stata 13 (StataCorp, USA). To evaluate the primary outcome (restoration survival), we  performed a survival analysis. Additionally an intention to treat (ITT) analysis were done at 24 months of follow-up. Cox Regression with shared frailty was performed to assess association between restoration failure and independent variables (α = 5%). RESULTS: A total of 324 restorations were performed in 145 children. The survival for H/M group was 58.2% and 60.1% for ENC, with no difference (p = 0.738). Occlusoproximal restorations had lower survival rate when compared to occlusal ones (HR = 3.83; p < 0.001). CONCLUSIONS: The survival rate in primary molars is not influenced by the different supply forms of GIC. Also, occlusoproximal restorations present reduced performances when compared to occlusal cavities. TRIAL REGISTRATION: This randomized clinical trial was registered on ClinicalTrials.Gov on 10/15/2014 under protocol (NCT02274142).

Impact of different restorative treatments for deep caries lesion in primary teeth (CEPECO 1) - study protocol for a noninferiority randomized clinical trial.

BACKGROUND: Due to the lack of evidence to determine the best treatment for deep cavitated caries lesions in primary molars, the search for an effective restorative technique, which results in a minimal discomfort to patients, and reduce the time needed for the treatment, becomes relevant. The objective of this randomized clinical trial was to evaluate if high-viscosity glass ionomer cement (HVGIC) restorations is noninferior to restoration with calcium hydroxide cement associated with HVGIC for treatment of deep lesions in primary molars, as well as the impact of the treatments on cost and discomfort of the patient. METHODS: A non-inferiority randomized clinical trial with two parallels arms (1:1) will be conducted. Children with 4 to 8 years will be selected at Clinic of Pediatric Dentistry at Ibirapuera University. 108 teeth will be randomized into two groups: (1) Calcium hydroxide cement associated with HVGIC and (2) HVGIC restoration. Primary outcome will be considered the pulp vitality and to be evaluated after 6, 12, 18 and 24 months by two calibrated examiners. Survival of restorations will also be evaluated in the equal intervals. The duration of dentals treatment and the cost of all materials used will be considered for estimating of cost-efficacy of each treatment. Individual discomfort will be measured after each dental procedure using the Wong-Baker's Facial Scale. For the primary outcome, Kaplan-Meier survival and the long-rank test will be used to comparison between the groups. Cox regression will be performed to assess the influence of variables on the outcome. For all analyzes, the significance level is set at 5%. DISCUSSION: Based on the philosophy of ART, our hypothesis is that the HVGIC restoration is a possible approach to restore the deep caries lesion with pulp vitality without the use of rubber dam and anesthesia. TRIAL REGISTRATION: Clinicaltrials.gov registration NCT02903979 . Registered on June 9th 2016.

Laser for bone healing after oral surgery: systematic review.

The purpose of this study is to perform a systematic review on the use of lasers in oral surgery for bone healing. Selection of articles was carried out by two evaluators in Pubmed and Web of Science databases for published articles and OpenGray for gray literature. Search strategy was developed based on the PICO Question "Does the use of lasers after oral surgery improve bone healing?". Eligibility criteria were: being on laser; evaluate bone healing; involve oral surgery; do not be about implant, periodontics, orthodontics, osteonecrosis or radiotherapy, nor revisions, clinical cases, etc. Data were collected from each article in a structured spreadsheet and a descriptive analysis was performed. Risk assessment of bias of the articles was carried out through the tool elaborated by the Cochrane collaboration. A total of 827 potentially relevant references were identified. No articles were found in OpenGray. Eleven articles met the eligibility criteria and were included in the systematic review. Most of studies were in vivo and in jaw, being conducted with low-power lasers which were applied immediately after the surgical procedure of extraction. Neoformation and bone density were the outcomes of choice and there was a tendency of increase in bone density, neoformation, regeneration, mineralization, or bone condensation when laser was applied. Regarding the bias risk assessment, studies were not clear in reporting most of the parameters. Low-power laser therapy seems to reduce time of bone healing in oral surgery, although there are no defined protocols and the level of evidence is still considered weak.

Analysis of the frequency of visualization of morphological variations in anatomical bone features in the mandibular interforaminal region through cone-beam computed tomography.

PURPOSE: The purpose of this study was to analyze the frequency of visualization of anatomical bone features and their possible variations in the mandibular interforaminal region through cone-beam computed tomography (CBCT). METHODS: This is a cross-sectional study that evaluated CBCT scans of the mandible of 141 women and 61 men, obtained by imaging archives from two private clinics of dental radiology. The study analyzed the frequency of visualization of: lingual symphyseal foramen (LSF), additional mental foramen (AdMF), absence of mental foramen (AbMF), mandibular incisive canal (MIC), and anterior loop (AL). Length measurements for MIC and AL were determined at first and following that the respective distances towards vestibular and lingual cortical walls were also individually verified. Statistical analyses included: Student's t test, Chi-square test, and ANOVA for the evaluation of the anatomical features observed through panoramic and parasagittal images' reconstructions. RESULTS: LSF presence was found in 97%, MIC in 75.9%, AL in 24%, AdMF in 4.7%, and AbMF in 2.5%. Chi-square tests demonstrated value results of p < 0.05 only for the presence of left AL in women when compared to men. Mean values for length measures of MIC and AL were of 10.1 and 2.12 mm, respectively. Mean distance from AL towards vestibular and lingual cortical walls was of 2.53 and 4.05 mm, respectively. CONCLUSION: Anatomical variability concerning the mandibular interforaminal region emphasizes the importance of performing CBCT in pre-operative assessment of the mandible for surgical procedures with oral implants.

Evaluation of the Post Orthognathic Surgery Satisfaction: a Comparative Cross-Sectional Study of Patients Class II and III.

The aim of this study was to analyze the degree of postoperative satisfaction regarding facial and dental esthetics, masticatory and respiratory function, and psychosocial factors in patients with dentofacial deformity Class II compared with Class III. The patients were divided into 2 groups with 50 patients in Group 1 (Class II) and 30 patients in Group 2 (Class III). Assessing the degree of postoperative satisfaction, the authors did not observe a significant difference between the groups in terms of improvements in the aesthetic and functional aspects and the psychological impact of the treatment. It can be concluded that regardless of the type of dentofacial changes, the treatment well indicated and conducted, results in significant positive effects on patients lives, both aesthetically and in the function, and psychosocial great benefit.

ART is an alternative for restoring occlusoproximal cavities in primary teeth - evidence from an updated systematic review and meta-analysis.

BACKGROUND: A previous systematic review showed that atraumatic restorative treatment (ART) can be an option to restore the occlusoproximal cavities in primary teeth; however, few studies fulfilled the criteria of inclusion to generate a high level of evidence. AIM: To update the existing systematic review and address questions regarding survival rate of ART restorations compared to the conventional approach in occlusoproximal cavities in primary molars. DESIGN: The search was extended beyond the original search through the PubMed/MEDLINE database up to February 2016. Furthermore, Web of Science and EMBASE were searched. The inclusion criteria were subjects related to the scope of the systematic review. After selection by title and abstract, potentially eligible articles were read in full and included in accordance with exclusion criteria. Meta-analysis was carried out with the outcome being the survival rate of restorations. RESULTS: The search strategy identified 560 potentially relevant studies, in addition to 127 from the original systematic review. A total of four articles were included in the qualitative and quantitative analyses. Meta-analysis showed no statistically significant difference between ART and conventional approaches in survival rate of occlusoproximal cavities (OR = 0.887, 95% CI: 0.574-1.371). CONCLUSION: ART restorations have similar survival rate compared to conventional treatment and can be considered an option to restore occlusoproximal cavities in primary molars.

Oral health status of children and young adults with autism spectrum disorders: systematic review and meta-analysis.

BACKGROUND: Individuals with special needs are often affected by oral disorders such as dental caries and periodontal disease. Current data regarding prevalence of these conditions in individuals with autism spectrum disorders (ASD) are controversial. AIM: To conduct a systematic review and meta-analysis to verify the prevalence of dental caries and periodontal disease in individuals with ASD, especially children and young adults. DESIGN: Searches were conducted through MEDLINE/PubMed, Web of Science, and Scopus databases in December 2015. Studies were included if fulfilled the following eligibility criteria: to evaluate the oral health status of individuals with ASD; to be an observational study; and to assess the prevalence of dental caries and/or periodontal disease. Meta-analyses were conducted considering prevalence of dental caries and periodontal disease in individuals as outcome. RESULTS: Search strategy identified 928 potentially relevant articles and seven of them were included in this review. All included studies reported dental caries prevalence, and the pooled prevalence was 60.6% (95% CI: 44.0-75.1). Moreover, only three studies showed prevalence of periodontal disease, resulting in pooled prevalence of 69.4% (95% CI: 47.6-85.0). CONCLUSION: Prevalence of dental caries and periodontal disease in children and young adults with ASD can be considered as high, pointing to the need for oral health policies focused on these individuals.

Caries lesion prevention and arrestment in approximal surfaces in contact with glass ionomer cement restorations - A systematic review and meta-analysis.

BACKGROUND: Studies have suggested that in the presence of approximal cavities, the approximal surface in contact with this one shows a higher risk in the development of caries lesions. AIM: To evaluate the ability of dental materials to prevent and to arrest caries lesion in approximal surfaces in contact with occlusoproximal restorations. DESIGN: Two independent reviewers performed a literature search in PubMed through November 2014. The inclusion criteria were: (1) subject related to the scope of this systematic review, (2) study with follow-up, (3) not performed in specific groups, (4) to have a comparison group. After selection by title and abstract, potentially eligible articles were read in full. Meta-analysis was carried out considering the outcome as caries lesion progression or arrestment. RESULTS: The search strategy identified 772 potentially relevant studies, and 10 of them were included in the review (six laboratory studies and four longitudinal trials). For the longitudinal clinical trials, no difference was verified among the materials (OR = 0.680,95%CI:0.233-1.983). When a meta-analysis was performed for laboratory studies, GIC was significantly associated with better ability to arrest caries lesions (OR = 0.153,95%CI:0.060-0.391). CONCLUSIONS: In laboratory studies, GIC shows better ability to arrest caries lesion in approximal adjacent surfaces, but this ability was not confirmed in longitudinal clinical trials.
