A Systematic Review of Research on Guided Access Cavity Preparation Endodontic Treatment: Dentin Preservation Perspectives.

Abstract

Purpose: Guided access cavity preparation (GACP) is an endodontic procedure utilizing stents, guide sleeves, or dynamic guides to facilitate the proper formation of access cavities. This paper aims to evaluate the significance of research on guided access cavity preparation in endodontic treatment concerning dentin preservation. In the context of dentin preservation, this paper provides a thorough scoping review of a variety of methodologies for evaluating the accuracy of guided access cavity preparation.

Materials and methods: Article searches were conducted using Tthe keywords "Guide Access Cavity Preparation" AND "Static Guide OR 3D Printing Template" AND "Dynamic Guide through digital databases including PubMed, Scopus, Cochrane Library, Science Direct, and Google Scholar. Research articles published in English within the past five years (2019-2024) and in accordance with the PCC (Population, Concept, and Context) framework were also included in the study. Articles from the meta-analysis or systematic review study type, those that were not accessible in full text or in a paid format, and those that did not assess the use of guided endodontics in endodontic surgery were excluded. This scoping review adheres to the Preferred Reporting Items for Systematic Reviews without Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) criteria.

Results: A total of 12 articles were reviewed, encompassing various locations, designs, type, and samples, which demonstrated the use of guided access cavity preparation has significant clinical applications and can provide accurate results in endodontic therapy.

Conclusion: Article searches were conducted using the keywords "Guide Access Cavity Preparation" AND 'Static Guide OR 3D Printing Template' AND" Dynamic Guide through digital databases including PubMed, Scopus, Cochrane Library, Science Direct, and Google Scholar. Research articles published in English within the past five years (2019-2024) and in accordance with the PCC (Population, Concept, and Context) framework were also included in the study. Articles from the meta-analysis or systematic review study type, those that were not accessible in full text or in a paid format, and those that did not assess the use of guided endodontics in endodontic surgery were excluded. This scoping review adheres to the Preferred Reporting Items for Systematic Reviews without Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) criteria. Studies show that advanced technologies in guided access cavity preparation endodontic treatment can improve dentin preservation, improve accuracy and predictability, particularly for root canal anomalies and difficult teeth, but clinicians must consider limitations and clinical applications. Clinicians must evaluate the limitations and clinical applications of guided endodontic access prior to its implementation.
