Dental pain and associated factors among pregnant women: an observational study.

The present study aimed to determine the prevalence of dental pain during pregnancy and its association with sociodemographic factors and oral health conditions among 315 pregnant women in South Brazil. Participants were interviewed to obtain sociodemographic data, such as age, educational level, employment status, family income, and marital and parity status. Medical and dental histories were also collected, including the occurrence of dental pain and the use of dental services during pregnancy.

Pulp tissue dissolution capacity of sodium hypochlorite combined with cetrimide and polypropylene glycol.

This study evaluated the influence of the addition of cetrimide and polypropylene glycol to sodium hypochlorite (NaOCl) on its capacity to dissolve pulp tissue. Bovine pulp fragments with standardized weight and volume were immersed for 5, 15 and 30 min in 2 mL of NaOCl and Hypoclean (NaOCl added with cetrimide and polypropylene glycol) solutions at 5.25%, 2.

Influence of EDTA and dentine in tissue dissolution ability of sodium hypochlorite.

This study verified whether ethylenediaminetetraacetic acid (EDTA) influences the pulp tissue dissolution capability of different concentrations of NaOCl, in the presence of dentine. NaOCl and EDTA solutions were simultaneously mixed in flasks either containing a dentine disc or those not containing a dentine disc. Previously weighed bovine pulp tissues were immersed in the solutions for 5, 15 and 30 min.

Influence of water concentration on the etching aggressiveness of self-etch primers to ground primary enamel.

Purpose: The purpose of this study was to investigate the influence of water concentration in self-etch primers on their etching aggressiveness to ground primary human enamel.

Methods: Five hydroxylethyl methacrylate/glycerol dimethacrylate phosphate-based experimental self-etch primers with the same pH (1.1) and different water concentrations (0%, 5%, 10%, 20%, or 40%) were formulated.
