Phytochemicals in vital tooth bleaching: Spectrophotometric evaluation of efficacy with papaya, pineapple, or kiwi extracts and 30% hydrogen peroxide.

Context: Dental bleaching, a common cosmetic treatment, typically uses hydrogen peroxide (HO). Yet, the search for natural options has prompted an investigation into fruit extract efficacies such as papain, bromelain, and actinidin for tooth whitening.

Aim: The aim of this study was to evaluate the efficacy of 30% hydrogen peroxide and fruit extracts (papaya, pineapple, and kiwi) on human enamel using a spectrophotometer at different time intervals.

Assessment of Smear Layer Removal and Push-Out Bond Strength Efficacy of Traditional and Herbal Root Canal Irrigants Across Different Root Levels: An In Vitro Study.

Introduction: Endodontic therapy requires meticulous root canal debridement, pathogen elimination, and effective obturation to prevent microbial intrusion. The presence of the smear layer hinders sealer penetration, compromising sealing effectiveness. Sodium hypochlorite and chlorhexidine are esteemed endodontic irrigants.

Mucormycosis and COVID-19: An epidemic within a pandemic in India.
