Abstract

<p>The purpose of the present study was to compare the efficacy of nanofilled and microfilled resin- modified glass ionomer as pits and fissure sealants in permanent molar teeth. Ninety six teeth having fissure at the occlusal surface were randomly divided into two groups: Group I: Treated by nanofilled resin-modified glass ionomer sealant and Group II: Treated by microfilled resin- modified glass ionomer sealants. Clinical assessment was performed by modified Ryge´s criteria by means of retention, color match, marginal adaptation at 3, 6, and 12 months follow-up visit. Chi-square test was used for testing differences between the two groups; a value of p&lt;0.05 was considered as statistically significant. The results revealed that at 12 months observation period, nanofilled resin-modified glass ionomer sealant showed better retention, color stability and marginal adaptation than that of microfilled resin-modified glass ionomer sealants. Furthermore, the differences between two groups in respect to marginal adaptation and color match were statistically significant (p&lt;0.05). It can be concluded that nanofilled resin-modified glass ionomer sealant could be a better alternative to microfilled resin- modified glass ionomer sealant.</p>

Highlights

Occlusal surfaces of molar teeth are considered to be highly susceptible to caries development because of their morphological complexity and plaque accumulation
They were grouped into two: In Group I, the right sided 48 teeth were restored with nanofilled resin-modified glass ionomer sealant (KetacTM Nano 100, 3M ESPE, Seefeld, Germany) and in Group II, the left sided 48 teeth were restored with microfilled resin-modified glass ionomer sealant (Hybond Resiglass, Shofu, Kyoto, Japan)
The results of sealant retention, marginal adaptation and color matches in the present study corresponded to a previous study.[12]

Summary

Introduction

Occlusal surfaces of molar teeth are considered to be highly susceptible to caries development because of their morphological complexity (as fissure or pits and fissure) and plaque accumulation. Difficulties with brushing during tooth eruption and hypomineralization of Pits and Fissures in children and adolescents lead to early initiation and intensive progression of occlusal caries. The molar teeth have many grooves (fissures) and pits on the chewing (occlusal) surface and on the buccal and palatal surface which can be very difficult to keep clean. These are two sites most susceptible to developing decay.[4]
