Antimicrobial resistance, integron carriage, and gyrA and gyrB mutations in Pseudomonas aeruginosa isolated from dogs with otitis externa and pyoderma in Brazil.

Background: Pseudomonas aeruginosa is associated with otitis and pyoderma in dogs and is frequently resistant to several antimicrobial drugs. Resistance genes can be carried by integrons with quinolone resistance mainly due to mutations in DNA topoisomerases II and IV.

Objective: To evaluate the antimicrobial susceptibility, integron carriage, and gyrA and gyrB mutations in P.

Obesity and periodontitis: systematic review and meta-analysis.

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).

Dental fluorosis in the primary dentition and intake of manufactured soy-based foods with fluoride.

Background & Aims: To identify manufactured soy-based products more recommended by pediatricians and nutritionists; to determine fluoride concentrations in these products; to evaluate children concerning fluorosis in primary teeth and its association with the consumption of soy-based products.

Methods: Pediatricians and Nutritionists answered a questionnaire about soy-based products they most recommended to children. Fluoride concentrations of the 10 products more cited were analyzed with the ion-specific electrode.
