The scope of this study was to conduct a systematic review of the studies on the association between obesity and periodontitis. The methods applied included a literature search strategy and selection of studies using inclusion and exclusion in accordance with the criteria for characteristics of the studies and meta-analysis. The research was conducted in the PubMed, Embase and Lilacs databases through 2010.

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.

Impact of bariatric surgery on oral health conditions: 6-months cohort study.

Objectives: We evaluate oral health conditions before and after bariatric surgery.

Methods: The sample was composed of 59 patients who had undergone Roux-en-Y gastric bypass (RYGB). Salivary flow, periodontal pocket depth and dental wear were evaluated before and after 6 months of surgery.

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).

Evaluation of an Experimental Gel Containing Euclea natalensis: An In Vitro Study.

Objective. To evaluate the effect of an experimental gel containing Euclea natalensis extract on dentin permeability. Methods.

Gastroesophageal reflux, dental erosion, and halitosis in epidemiological surveys: a systematic review.

In published studies, it has been suggested that dental wear is associated with gastroesophageal reflux disease (GERD). This systematic review was carried out to evaluate the association of GERD, dental erosion, and halitosis and to compare the indices adopted in epidemiological surveys. The Medline database (until October, 2011) was searched systematically to identify studies evaluating the prevalence of oral alterations, such as dental erosion and halitosis, in patients with GERD symptoms.

Evaluation of oral health status and salivary flow rate in obese patients after bariatric surgery.

Objectives: The aim of this study was to identify the prevalence of dental caries, periodontal diseases and tooth wear in bariatric patients, and relate the oral health conditions to saliva flow.

Methods: Fifty-two patients who had undergone bariatric surgery (Roux-en-Y gastric bypass) and 50 severely obese patients indicated for bariatric surgery were submitted to clinical examinations with regard to dental caries (DMFT index), periodontal condition (CPI index), dental wear (DWI index - Dental wear index) and saliva flow. The data were statistically analyzed by the Student's-t, Mann-Whitney, Spearman Correlation and Chi-square (χ(2)) tests at 5% significance level.

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.

Interfaces between bariatric surgery and oral health: a longitudinal survey.

Purpose: To evaluate oral changes, such as dental caries, periodontal disease, dental wear and salivary flow in bariatric patients. Fifty four obese patients who underwent bariatric surgery were studied before (n=54), up after 3 months (n=24) and 6 months (n=16).

Methods: Indices for evaluating oral conditions were: DMFT, CPI, DWI and salivary flow.

Alveolar bone loss and periodontal status in a bariatric patient: a brief review and case report.

To review the effects of obesity surgery on oral health and to present a case report of the periodontal condition of an obese woman who underwent bariatric surgery. A search of studies related to bariatric surgery and oral health was made in PubMed. For case report, BMI, salivary flow, and periodontal condition were evaluated during three different periods.

Effect of propolis gel on the in vitro reduction of dentin permeability.

Objective: The aim of this study was to evaluate the capacity of potassium oxalate, fluoride gel and two kinds of propolis gel to reduce the hydraulic conductance of dentin, in vitro.

Material And Methods: The methodology used for the measurement of hydraulic conductance of dentin in the present study was based on a model proposed in literature. Thirty-six 1-mm-thick dentin discs, obtained from extracted human third molars were divided into 4 groups (n=9).

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.

Dental caries in adolescents from public schools in Maputo, Mozambique.

Aim: To assess dental caries prevalence in adolescents at urban and sub-urban areas of Maputo-City, Mozambique and to identify its relationship with dental fluorosis, dental plaque, nutritional status, frequency of sugar consumption and the concentration of fluoride in public water supply.

Methods: Subjects (n=601) were randomly selected from five urban schools and five sub-urban schools. Clinical examinations were performed under standardised conditions by a trained examiner using DMFT index, SiC index, fluorosis index, PHP, BMI, a sugar consumption questionnaire and water supply analysis.

Effectiveness of 0.50% and 0.75% chlorhexidine dentifrices in orthodontic patients: a double-blind and randomized controlled trial.

Introduction: In this double-blind and randomized controlled trial, we analyzed whether a lower concentration of chlorhexidine in dentifrices could reduce the risk of tooth staining without compromising its effectiveness in controlling gingivitis, bleeding, and dental plaque.

Methods: Volunteers with fixed orthodontic appliances were randomly divided into 3 groups: control, 1100 ppm F, NaF (n = 27); experimental, chlorhexidine 0.50% (n = 27); and experimental, chlorhexidine 0.
