Autor: Amauri Favieri, Ernani da Costa Abad, Antônio J.R. Castro, Isabela N. Rôças, José F. Siqueira, Sérgio M. Gahyva

Publikováno v: Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontology. 90:647-650

Objective: The purpose of this in vitro study was to evaluate the coronal leakage of microorganisms from saliva into root canals filled by 3 obturation techniques. Study Design: Obturated canals were mounted in an apparatus and then exposed to human

Endodontic sealers that possess both optimum flow ability and antimicrobial properties may theoretically assist in the elimination of microorganisms located in confined areas of the root canal system. The antimicrobial effects and the flow rate of th

Publikováno v: Journal of Endodontics. 27:673-675

This study evaluated the ability of three materials--a resinous root canal sealer (Sealer 26) prepared in a thick consistence, a reinforced zinc oxide-eugenol cement (IRM), and a glass-ionomer cement (Fuji IX)--in preventing bacterial leakage. Retrof

Evidence suggests that diabetic patients are more significantly affected by problems of endodontic origin. This study sought to radiographically and histologically examine the development of periradicular inflammation in control and in diabetic rats

Direct genotoxicity and mutagenicity of endodontic substances and materials as evaluated by two prokaryotic test systems

Autor: José Freitas Siqueira Junior, Sérgio M. Gahyva

Publikováno v: Journal of applied oral science : revista FOB. 13(4)

Substances and materials used in endodontic therapy come into close contact with the periradicular tissues via apical foramen and foramina. Consequently, they should possess biocompatibility. There are currently few studies describing the genotoxic a

Publikováno v: Journal of endodontics. 28(6)

The purpose of this prospective study was to evaluate the incidence of postoperative pain after intracanal procedures based on an antimicrobial strategy. Data were examined from 627 teeth that had necrotic pulps or required retreatment. Information w
