Observation of Saccharomyces cerevisiae in blood of patient undergoing root canal treatment.

abstract：AIM:The aim of this study was to test the null hypothesis that sodium hypochlorite irrigation of root canals does not alter the properties of dentine and contribute to the weakening of root-treated teeth. METHODOLOGY:The effect of two concentrations (0.5%, 5.25%) of sodium hypochlorite (NaOCl) and saline on (i) the el...
