COMPARATIVE EVALUATION OF TRADITIONAL ENDODONTIC ACCESS AND MINIMALLY INVASIVE ACCESS CAVITY IN TERMS OF RELATIVE FRACTURE STRENGTH IN ENDODONTICALLY TREATED MANDIBULAR MOLARS - A SYSTEMATIC REVIEW OF IN-VITRO STUDIES.

Abstract

Objective: This systematic review was executed with the aim of evaluating whether minimally invasive access preparations increase the fracture strength of endodontically treated mandibular molars in comparison to traditional endodontic access cavity preparations. A Methodology: comprehensive search of electronic databases namely, Google scholar, Web of Science, Scopus, Cochrane Library, Wiley Online Library, PubMed, Science Direct and relevant online registers was carried out, using appropriate MeSH terms and text words. PICOs criteria was decided prior to the article selection process. The identication and screening process was coherent with PRISMA statement and suitable full text reports were nalised for the study. Additionally, the quality and risk of bias of selected studies were also assessed. A total of 633 articles were procured from Results: online mediums. After the screening process, six studies in accordance with inclusion criteria were nalised for this review. Discrepancies were noted in the sample size, fracture resistance test methodologies and fracture strength values of nalised studies. Out of 6, a single study was deemed as having moderate risk of bias and the rest, low risk of bias. Improvement in frac Conclusion: ture strength of endodontically treated mandibular molars with conservative access approach was not evident. Ideally, this assessment should be made via randomized clinical trials against the reference intervention.
