6. Effect of different stripping techniques on pulpal temperature: in vitro study
RESUMO Introdução: o desgaste proximal do esmalte é um procedimento clínico rotineiro utilizado na Ortodontia para se criar espaços ou equilibrar discrepâncias de tamanho dentário. Esse procedimento pode resultar em transferência de calor para a polpa, predispondo-a a mudanças histopatológicas e necrose do tecido pulpar. Objetivo: medir as mudan

7. Effect of the time-point of acid etching on the persistence of sealer residues after using different dental cleaning protocols
Abstract: Endodontic sealer residues remaining within the pulp chamber dentin after root canal obturation and cleaning with various solvents may compromise the appearance and the durability of dental restorations. Acid etching is routinely performed prior to application of dentine adhesive systems, but is effect on residual sealer material and the optimal ti

9. Prevalence and morphometric analysis of three-rooted mandibular first molars in a Brazilian subpopulation
ABSTRACT The knowledge of the internal anatomy of three-rooted mandibular molars may help clinicians to diagnose and plan the root canal treatment in order to provide adequate therapy when this variation is present. Objectives: To determine the prevalence of three-rooted mandibular molars in a Brazilian population using cone beam computed tomography (CBCT)

10. Rat dental pulp stem cells: isolation and phenotypic characterization method aiming bone tissue bioengineering
ABSTRACT: Dental pulp stem cells (DPSC) have been showing a considerable potential for regenerative medicine. Pulps were collected from lower incisors (n=2) through direct access of the tooth pulp chamber. The isolated cells were cultured in alfa-MEM 10% FBS, in standard culture conditions. At the third passage, DPSC were characterized by flow cytometry (MHC

11. Effect of new innovative restorative carbomised glass cement on intrapulpal temperature rise: an ex-vivo study
Abstract This study aimed to evaluate the temperature changes that occurred in the pulp chamber when using GCP Glass Carbomer Fill (GCP) and two different resin-modified glass-ionomer (RGI) restorative materials at different dentin thicknesses. A standardized Class I occlusal cavity with 1 mm or 2 mm dentin thickness was prepared in the extracted human molar

12. Evaluation of an experimental rat model for comparative studies of bleaching agents
ABSTRACT Dental materials in general are tested in different animal models prior to the clinical use in humans, except for bleaching agents. Objectives To evaluate an experimental rat model for comparative studies of bleaching agents, by investigating the influence of different concentrations and application times of H2O2 gel in the pulp tissue during in-o
