[ effect of three temporary restorative material thickness coronal micro leakage in endodontics- an in - vitro study]

ABSTRACT

Introduction: Maintaining an adequate coronal access seal is an integral part of multiple-visit endodontic therapy or after root canal treatment until crown reconstruction. This is provided by filling the access cavity with temporary restorative materials. The thickness of the temporary restorative materials is one of the important factors in preventing of coronal microleakage
