IntroductionMicroorganisms are pivotal contributors to pulp and periapical pathology, often culminating in endodontic treatment failures. The successful outcome of such treatment hinges on the effective eradication of microbial flora through various interventions, including intracanal medicaments (ICMs). However, Enterococcus faecalis (E. faecalis), a highly adaptive Gram-positive bacterium, exhibits remarkable resilience and can persist even after rigorous disinfection efforts. This study explores the efficacy of two ICMs, calcium hydroxide-based triple antibiotic paste (TAP) and a novel alternative containing bromelain, derived from pineapples, in combating E. faecalis infections in vivo.
