Antimicrobial efficacy of alternative root canal disinfection strategies: An evaluation on multiple working models.

Researching disinfection strategies is pivotal because effectively eliminating bacteria and their byproducts during root canal treatment (RCT) remains a challenge. This study investigated the antimicrobial efficacy of natural antimicrobial compounds, propolis (PRO) and copaiba oil-resin (COR), compared to conventional agents in Endodontics. Antimicrobials were tested against endodontic pathogens via macrodilution with standardized inoculums to determine the minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC).

Streptococcus mutans serotyping, collagen-binding genes and Candida albicans in dentin carious lesions: a molecular approach.

Objectives: This cross-sectional study aimed to evaluate the occurrence of Streptococcus spp., Streptococcus mutans, its serotypes (c, e, f, and k), collagen-binding genes (cnm/cbm), and Candida albicans in medium deep (D2) and deep (D3) dentin carious lesions of permanent teeth.

Materials And Methods: Carious dentin was collected from D2 (n = 23) and D3 (n = 24) lesions in posterior teeth from 31 individuals.

[Effect of an intervention in physical education classes on the reduction of sedentary behavior in adolescents].

This study aimed to analyze the effect of different intervention strategies in physical education classes on the reduction of sedentary time. This is a randomized, school-based intervention with factorial characteristics, carried out with freshmen high school students from 11 full-time schools, allocated in three intervention situations: (A) schools with two extra physical education classes per week; (B) schools with training and engagement actions for physical education teachers; (C) Schools with both A and B strategies; and (D) a group of control schools. Accelerometry was used to obtain the effect measure of the main outcome (sedentary behavior).

Nasopharyngeal carriage of Streptococcus pneumoniae among Brazilian children: Interplay with viral co-infection.

Nasopharyngeal transmission of Streptococcus pneumoniae is a prerequisite for the development of pneumococcal diseases. Previous studies have reported a relationship between respiratory viruses and S. pneumoniae infections.

Selective IgM deficiency: evaluation of 75 patients according to different diagnostic criteria.

Selective IgM deficiency (SIgMD) has recently been included in the inborn errors of immunity classification. SIgMD has conflicting diagnostic criteria and diverse clinical and immunological findings. We aimed to assess the clinical and laboratory profiles of patients with SIgMD and to compare the data of patients diagnosed using two inclusion criteria.
