the purpose of this study was to assess the in vitro effect of ascorbic acid on the antibacterial substantivity of tetraclean in bovine root dentin pretreated with sodium hypochlorite (naocl).eighty dentin tubes prepared from bovine incisor teeth were infected with enterococcus faecalis for 14 days. the specimens were divided into five groups as follows: tetraclean; 5.25% naocl/tetraclean; 5.25...

introduction: the purpose of this in vitro study was to assess the antifungal activity of final canal rinse with either three concentrations of sodium hypochlorite (naocl) (0.5, 2.6 and 6%), two concentrations of chlorhexidine (chx) (2% and 0.2%), mtad, tetraclean, hypoclean and chlor-xtra on candida albicans (c. albicans ) in a human tooth model. methods and materials: two hundred and thirty f...

i ntroduction: due to the complex anatomy of the root canal system and high surface tension of common root canal irrigants (rci), conducting an investigation on rcis containing surfactants is a priority. the aim of this in vitro study was to verify the antibacterial potential of rci with low surface tension in root canals infected with enterococcus faecalis ( e. faecalis ). methods and material...

Local application of antibiotics within the root canal system may be a more effective mode for delivering the drug. Tetracyclines have been used to remove the smear layer from instrumented root canal walls, for irrigation of retrograde cavities during periapical surgical procedures, and as an intracanal medicament. Substantivity of tetracyclines has been shown for up to at least 12 weeks. BioPu...
