Do Ultraconservative Access Cavities Hinder Endodontic Reintervention in Mandibular Incisors? A Laboratory Investigation.

This study assessed the influence of the type of endodontic access cavity on endodontic reintervention. Twenty mandibular central incisors were distributed into two groups ( = 10): TradAC group-traditional access cavities and UltraAC.Inc group-ultraconservative access cavities.
