Exploring the Impact of Access Cavity Designs on Canal Orifice Localization and Debris Presence: A Scoping Review

One of the primary objectives in endodontics is to achieve thorough cleaning and disinfection of the root canal system during an endodontic procedure. This aims to reduce microbial contamination and prevent the development of endodontic lesions. To attain this goal, it is imperative to establish access to the endodontic space that allows for the complete removal of pulp tissue and the accurate identification of canal orifices while preserving the anatomical integrity of the root floor and pulp chamber as much as possible. In this scoping review, we aim to explore aspects related to the identification of canal orifices and the presence of pulp debris and residues during endodontic treatment. Specifically, we aim to assess whether and to what extent the design of the access cavity impacts these factors.

The scoping review was conducted and prepared following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines (PRISMA Extension for Scoping Reviews [PRISMA-ScR]).

The search yielded a total of 3697 bibliographic sources. After eliminating duplicates and applying eligibility criteria, only 10 studies were included.

In conclusion, our review, conducted following PRISMA guidelines, includes 10 studies and suggests a potential trend: conservative techniques may generate more debris, whereas guided techniques exhibit superior precision in locating canal openings.
