Scanning electron microscopy evaluation of chitosan and carboxymethyl chitosan as retrograde smear layer removing agents.

Background: The smear layer acts as a physical barrier against penetration of root canal medicaments and sealers, thus compromising the seal leading to microleakage.

Objectives: This study was conducted to evaluate the efficacy of 17% ethylenediaminetetraacetic acid (EDTA), 0.2% chitosan solution, and 0.

Comparison of bond strength of different endodontic sealers to root dentin: An in vitro push-out test.

Aim: To compare the bond strength of four different endodontic sealers to root dentin through push-out test design.

Materials And Methods: Forty single-rooted teeth with completely formed apices were selected. Teeth were decoronated, and working length was determined.

Comparative evaluation of antimicrobial efficacy of triple antibiotic paste and calcium hydroxide using chitosan as carrier against Candida albicans and Enterococcus faecalis: An in vitro study.

Aim: To analyze the sustained release of intracanal medicaments with or without a carrier and testing their antimicrobial efficacy in root canal against Candida albicans and Enterococcus faecalis.

Materials And Methods: A total of 80 single-rooted anterior teeth were selected, root canal preparation was done, and teeth were divided into two halves and contaminated with C. albicans and E.
