Abstract

The preparation of an access cavity is the first part of endodontic treatment and is a key stage in the healing of both periapical and pulpal infections. It should allow endodontists to remove obstructions in the pulp chamber, locate all canal orifices and clean the entire root canal system with minimum coronal tooth structure removed. This has been done traditionally through establishing straight line access. The development of minimally invasive endodontics aimed to preserve as much of the natural tooth structure as possible, particularly dentine, while undertaking root canal treatment, resulting in the development of other access cavity preparations. This includes conservative, ultra conservative (ninja), truss, guided access, caries-orientated and restorative access cavities. These access cavity preparations also gained popularity due to increased magnification and enhanced lighting, allowing practitioners to visualise the pulpal space in greater detail throughout treatment.Our current recommendation is to conduct access cavities traditionally rather than conservatively. Ideally, conservative access cavities need magnification, which might not be available for all clinicians. With traditional access cavity, the procedure takes less time and it is more predictable to locate the canal orifices, deliver irrigation effectively, avoid iatrogenic damage with biomechanical preparation and achieve better obturation.
