Potential of chitosan oligosaccharide gel as a cavity cleanser against adhesive restoration adhesive on the cavity wall

Abstract

Cavity cleanser is a cavity cleaner with ideal properties such as being biocompatible, antibacterial,
removing smear layers, and not interfering with the adhesive bond. This study aims to examine the potential of gel
chitosan oligosaccharide (COS) as a cavity cleanser on the adhesion of the restoration to the cavity wall. Thirty-two
mandibular premolars with class V restorations are divided into two groups with 2% COS gel and 2% chlorhexidine
digluconate (CHX). Samples were immersed in 2% methylene blue, cut longitudinally, observed under a
stereomicroscope with 1x magnification, and scored 0-3. The Mann-Whitney test was used to see the potential of gel
COS as a cavity cleanser. The results showed a significant difference between the two groups at the edge of the
enamel junction restoration (p=0.038) and the dentin junction restoration (p=0.027). The mean microleakage score in
group 1 showed better results at the enamel junction (1.19± 1.328) and the dentin junction (2.00±1.211). It shows that
2% COS gel has the potential as a cavity cleanser. There was a significant difference between the two groups as a
cavity cleanser on the adhesion of adhesive restorations to the cavity wall.
