Access Cavity Opening: Challenges and Clinical Tips

Access cavity preparation is a critical first step in successful root canal treatment and plays a decisive role in canal location, instrumentation, and overall treatment outcome. Inadequate or improper access can lead to missed canals, procedural errors, and compromised prognosis, particularly in teeth with calcifications, extensive restorations, or altered anatomy. This lecture and video presentation discusses common problems encountered during access cavity opening and demonstrates practical tips and techniques to manage challenging cases. Emphasis is placed on proper case assessment, bur selection, use of magnification, and strategies to achieve safe and effective access while preserving tooth structure. The session aims to provide clinicians with simple, reproducible approaches to improve precision and predictability in endodontic access preparation.
