In Vitro Study To Investigate The Correlation Between Initial Anatomy And Final Preparation Of Root Canal That Is Sufficient To Achieve Efficient Irrigation And Hermetic Apical Obturation

The aim of study is to determine an obvious correlation between initial anatomy and root canal preparation size realizing efficient irrigation and hermetic apical obturation without over instrumentation in order to conserve apex integrity. The sample included 120 single root canal teeth which cleared and divided into 24 sub-group.
