Assessment of depth of penetration and antibiofilm properties of Boswellia sacra compared with calcium hydroxide intracanal medicament (in vitro study).

Successful endodontic treatment requires advanced materials to eliminate biofilm This study aims to assess the penetration depth and the effectiveness of Boswellia sacra as a novel intracanal medicament compared with calcium hydroxide against Enterococcus faecalis biofilm. 60 single-rooted teeth were decoronated, prepared and sterilised. Fifty teeth were contaminated with a culture of E.

Ultrastructural morphologic evaluation of root canal walls prepared by two rotary nickel-titanium systems: a comparative study.

Objective: To evaluate and compare the ultrastructural morphology, surface cleanliness, and roughness of root canal walls of extracted teeth after instrumentation with 2 different rotary nickel-titanium systems (ProTaper and NRT) when associated with the use of sodium hypochlorite and ethylenediaminetetraacetic acid combination as an irrigating regimen.

Study Design: A total of 40 freshly extracted single-rooted human mandibular premolars with fully developed apices and straight roots were selected. The roots were randomly divided into 2 experimental groups of 20 samples each according to the rotary system used in the preparation of the canals.
