Modern versus Traditional Endodontic Access Cavity Designs.

By creating a precise access cavity (AC) and finishing the pulp chamber, less invasive endodontic therapy attempts to improve conventional endodontic therapy. The cingulum, oblique ridge, and roof of the pulp chamber, which all play a vital role in functional activity, might be preserved to increase fracture resistance. To reduce tooth structure loss, endodontic new ACs have recently been created.
