This document describes the process for accessing and preparing root canals in various anterior teeth. It discusses the access cavity, penetration, enlargement, and finishing phases. For each tooth, it notes the typical root canal anatomy and challenges, and provides guidance on creating an optimal access cavity shape and starting point. Teeth covered include upper and lower central and lateral incisors, upper canines, and lower canines. The goal is to safely and efficiently access all root canals while minimizing removal of healthy tooth structure.
