Propolis effects in periodontal disease seem to affect coronavirus disease: a meta-analysis.

This meta-analysis aimed to investigate the effects of propolis on the severity of coronavirus disease symptoms by reducing periodontal disease. PubMed, EMBASE, SciELO, Web of Science, and SCOPUS databases were systematically searched. Studies have been conducted analyzing propolis's effects on COVID-19 and periodontitis.

Effect of Aging on the Vocal Muscle.

Introduction: Sarcopenia is a common and natural condition in the elderly, and leads to loss of muscle mass and function. In the presbylarynx there is atrophy of the vocal folds, however the degree of vocal muscle atrophy is poorly studied and the results are contradictory.

Aims: The aim of this study was to evaluate the effect of aging on the vocal muscle (thyroarytenoid muscle).

Nutritional status, tooth wear and quality of life in Brazilian schoolchildren.

Objective: To evaluate the correlation among nutritional status, tooth wear and quality of life in Brazilian schoolchildren.

Design: The study followed a cross-sectional design. Nutritional status was measured via anthropometry using BMI and tooth wear was measured using the Dental Wear Index; both these assessments were carried out by a trained recorder according to standard criteria.

Effect of natural gel product on bovine dentin erosion in vitro.

Objective: To evaluate the efficacy of Neem (Azadirachta indica) experimental gel for the prevention of erosive wear on bovine dentin, in vitro.

Material And Methods: One hundred dentin blocks were allocated into 5 experimental groups (20 samples each): C (control group, without gel); CG (control group, only base gel); F (fluoride gel, 1.23% NaF; pH 4.

An epidemiological scoring system for tooth wear and dental erosive wear.

Background: The prevalence and severity of tooth wear and dental erosion is rising in children and there is no consensus about an index to be employed.

Aim: To assess the reliability of an epidemiological scoring system dental wear index (DWI) to measure tooth wear and dental erosive wear.

Design: An epidemiological cross-sectional survey was conducted to evaluate and compare tooth wear and dental erosion using the dental wear index and erosion wear index (EWI).

Oral manifestations in HIV+ children in Mozambique.

The scope of this study was to identify the prevalence of oral manifestations in HIV+/AIDS patients at the DIA Pediatric Hospital of Maputo. All 90 patients were included in the research. Data on dental caries (dmft/DMFT index), soft tissues and saliva flow were analyzed.

Effect of iron gel on dentin permeability.

This study evaluated in vitro the effect of an experimental gel containing iron on the reduction of hydraulic conductance of dentin. Thirty-six 1-mm-thick dentin discs obtained from extracted human third molars were divided into 3 groups of 10 specimens each. The groups corresponded to the following experimental materials: 1.

[Prevalence of overweight and obesity, and associated factors in adolescents, at the central west area of the state São Paulo (SP, Brazil)].

The aim of the study was to evaluate the relationship between the Body Mass Index (BMI) and the DMFT index, in 207 adolescents aged 12 years old, from 8 public and private schools of the central west area of São Paulo State. From a sample of 380 12 year-old adolescents, both genders, 207 were examined. We used the index DMFT, CBI for weight, measured of stature and applied a questionnaire about alimentary habits, characteristic anthropometrics and physical activity.
