Mergoni G, et al. - Authors systematically reviewed the literature on the prevalence of Candida species in root canal infections. They performed extensive literature research in the most important electronic biomedical databases and identified additional studies from references from relevant articles. The occurrence of Candida spp. was seen in a small proportion of root canal infections; they noted 8.20% to be the overall prevalence of Candida spp. The most frequently isolated species was Candida albicans. Experts observed a significant heterogeneity among studies.
