Abstract

Aim: This study aimed to compare two different endodontic access concepts– traditional vs modern caries driven access cavity preparation- and their effect on the final restoration of the endodontically treated teeth taking in consideration the material of final restoration, regarding the effect of the access design and the afterwards restoration effect on the fracture resistance of the restoration.
Methodology: a total number of 120 human permanent molar were subjected to this study (in-vitro), all were divided into 2 main groups –60 molar each- classified according to the design of the endodontic access cavity performed with the molars of the first group was accessed through traditional design of access cavity , while the second group was accessed through a modern access cavity design called caries/restoration driven access cavity, in which the access is guided by caries where less natural tooth structure is removed.
Each group was then restored with a different type of restoration, and all were subjected to testing for fracture resistance.
Results: Less invasive endodontic therapy seeks to improve traditional endodontic treatment by establishing a highly accurate access cavity (AC) that will subsequently results in increased strength of the endodontically treated tooth through preserving more natural tooth structure and less restoration margins exposed to the occlusal stresses.
Conclusion: The involvement in functional activity could be kept promoting fracture resistance. Endodontic new ACs were recently created to decrease tooth structural loss. So, this study has shown that minimally invasive endodontics can be considered a challenge to the standard approach.
