The Effect of Primary Root Canal Treatment on Dentinal Tubule Penetration of Calcium Silicate-based Sealers during Endodontic Retreatment

CE Hours: 1.0

Description: The aim of this study was to evaluate the effect of previous root canal treatment on dentinal tubule penetration of calcium silicate–based sealers during endodontic retreatment and to compare 2 different (commonly used and modified) tubule penetration depth measurement techniques.

At the conclusion of this lecture, the reader will be able to: 

• Estimate dentinal tubule penetration depth of the root canal sealers by identifying different colored dyes under confocal laser scanning microscopy
• Select the most appropriate dentinal tubule penetration depth measurement technique for her/his study by comparing the previously tested methods and can judge the techniques used for this purpose
• Predict the dentinal tubule performance of different sealers during the secondary root canal treatment and can estimate the effect of primary root canal treatment on the dentinal tubule penetration performance of the sealer used during secondary root canal treatment
