Sex prediction through machine learning utilizing mandibular condyles, coronoid processes, and sigmoid notches features.

Characteristics of the mandible structures have been relevant in anthropological and forensic studies for sex prediction. This study aims to evaluate the coronoid process, condyle, and sigmoid notch patterns in sex prediction through supervised machine learning algorithms. Cephalometric radiographs from 410 dental records of patients were screened to investigate the morphology of the coronoid process, condyle, and sigmoid notch and the Co-Gn distance.

Periodontal parameters in orthodontically tractioned teeth: A systematic review and meta-analysis.

Objective: This systematic review aimed to evaluate periodontal parameters in orthodontically tractioned teeth compared with the respective non-tractioned contralateral teeth.

Methods: Search strategies were developed for six electronic databases and gray literature. Random-effects meta-analyses were performed for the outcomes of interest.

Effects of respiratory training on obstructive sleep apnea: systematic review and meta-analysis.

Purpose: This systematic review sought to answer the following focused question: "What are the effects of respiratory training devices on obstructive sleep apnea (OSA) outcomes in adults?" METHODS : The acronym "PICOS" was used to determine eligibility criteria, which consists of (P population) = adults with mild to moderate OSA, (I intervention) = spirometry devices or breathing exercises, (C comparison) = compared to no breathing exercises in adults (> 18 years) with mild to moderate OSA, (O outcomes) = improved sleep quality (sleep quality indexes) and improved apnea-hypopnea indexes (AHI), (S study types) = randomized, pseudo-randomized, and non-randomized clinical trials. The search was performed in the following databases: PubMed/Medline, LILACS, Scopus, Web of Science, Scopus, and Cochrane Library, in addition to gray literature through Google Scholar, Proquest, and Open Grey. The risk of bias was assessed using the Cochrane Collaboration tool.

Psychosocial changes in patients submitted to orthodontic surgery treatment: a systematic review and meta-analysis.

Objective: This systematic review aims to answer the following question: What is the psychological impact of orthognathic surgery on patients with dentofacial deformities undergoing orthodontic-surgical treatment?

Material And Methods: The search was adapted for each of the following databases: American and Caribbean Center on Health Sciences (LILACS), Cochrane Library, Embase, Psychinfo, PubMed/Medline, Scopus and Web of Science, and gray literature using Google Scholar, OpenGrey, and ProQuest. The risk of bias was assessed using the Joanna Briggs Institute Critical Assessment Checklist. This study performed estimates of interest, random-effects meta-analyses, and calculated heterogeneity using Higgins inconsistency index (I).

Risk factors associated with the stability of mini-implants and mini-plates: systematic review and meta-analysis.

Objective: The objective of this systematic review is to assess the risk factors associated with the stability of mini-implants and mini-plates in patients undergoing orthodontic treatment using temporary anchorage devices.

Material And Methods: Search strategies were developed for each electronic database (PubMed/Medline, LILACS, Scopus, Web of Science, Embase, and Cochrane Library) and gray literature (Google Scholar, Proquest, and Open Grey). The risk of bias was assessed using the Cochrane Collaboration tool for assessing the risk of bias and Meta-Analysis of Statistics Assessment and Review Instrument.

Front lines of the COVID-19 pandemic: what is the effectiveness of using personal protective equipment in health service environments?-a systematic review.

Purpose: This systematic review aimed to evaluate the effectiveness of the use of personal protective equipment (PPE) in closed environments, similar to waiting or exam rooms of healthcare facilities, in the face of exposure to a bioaerosol.

Methods: Combinations of words were selected for six electronic databases and for the gray literature. To consider the eligibility of the studies to be included/excluded, the acronym "PECOS" was used: humans and/or experimental models that simulate aerosol (Population); aerosol exposure and the use of masks/respirators (exposition/intervention); controlled or not controlled (comparison); effectiveness of PPE and the receiver exposure (outcomes); and randomized clinical studies or not, observational or laboratory simulation studies (Studies design).

Effect and longevity of botulinum toxin in the treatment of gummy smile: a meta-analysis and meta-regression.

Objective: The aim of this systematic review is to synthesize the evidence on the effectiveness and longevity of the botulinum toxin in the treatment of individuals with excessive gingival exposure.

Methods: The search was adapted to six electronic databases and gray literature. The risk of bias was assessed using the Cochrane Risk of Bias Assessment Tool for Non-Randomized and Randomized Studies of Interventions.

Is there scientific evidence of the mouthwashes effectiveness in reducing viral load in Covid-19? A systematic review.

Background: The aim of this research is to verify whether there is evidence in the literature regarding the decrease in viral load present in saliva after using three types of mouthwashes.

Material And Methods: Clinical and/or experimental studies that have used mouthwashes as a form of intervention to reduce the viral load in saliva were included. Combinations of words and appropriate truncations were adapted for each of the seven selected electronic bases including grey literature.
