Endodontic access cavity preparation: challenges and recent advancements

Odontogenic pain from various dental issues significantly impacts quality of life, necessitating effective treatment during emergency dental care. Endodontic access cavity preparation is essential for alleviating symptoms and preventing further infection. This procedure aims to achieve symptom relief while conserving as much tooth structure as possible. This paper discusses the importance of proper endodontic access, emphasising the balance between adequate disinfection and preserving tooth integrity. It also identifies challenges in endodontic access cavity preparation. This study reviews existing literature on endodontic access, examining different approaches to access cavity preparation and the tools and techniques used. Factors affecting access difficulty, including tooth anatomy, patient-related challenges and operator skills, are evaluated, alongside advancements in imaging and instrumentation. The review shows conservative techniques, like minimally invasive access cavities, which helps to preserve tooth structure but requires advanced skills and may risk incomplete disinfection. Cone beam computed tomography (CBCT) aids in complex cases, improving canal location accuracy. Operator skills and proper equipment are key to success. Traditional cavities offer better access but can weaken the tooth, while conservative approaches maintain structure but demand more expertise. Imaging tools, including CBCT, are beneficial for complex anatomy but can be costly. To conclude, effective endodontic access cavity preparation requires a balanced approach tailored to each case. While conservative methods offer advantages in preserving tooth structure, their success depends on operator expertise and equipment. Incorporating imaging advancements like CBCT can enhance access success, especially in anatomically complex cases, but careful assessment of case complexity remains crucial.
