Modern Endodontics: Access Preparation

Abstract

The primary objective of any endodontic procedure is to remove all organic debris from the intricate root canal system and to effectively seal the canal. The initial step in this treatment is the preparation of the access cavity, which occurs after a diagnostic and treatment plan has been established for the tooth. This phase is crucial, as it significantly impacts the ease and success of the subsequent treatment stages. Over the past few decades, endodontics has undergone substantial advancements in both technology and materials. These developments have notably altered various facets of endodontic treatment, particularly the process of creating access openings. Contemporary endodontic practices aim to improve traditional methods by employing less invasive techniques that facilitate the formation of an accurate access cavity and the refinement of the pulp chamber. Preserving anatomical features such as the cingulum, oblique ridge, and pulp chamber roof is vital for maintaining functional integrity and enhancing fracture resistance. Recent innovations in access cavity design focus on minimizing the loss of tooth structure. The advent of microscopes and sophisticated root canal instruments has raised the standard for preparing conservative access openings. Ultimately, the preservation of cervical dentin is essential for ensuring the normal function and longevity of the restored tooth. In recent years, the rise of minimally invasive endodontics has posed a significant challenge to traditional practices. This paper aims to showcase modern concepts in endodontic access preparation.
