Comparative Evaluation of Glass Ionomer and Resin-Based Fissure Sealants on Newly Erupted Permanent First Molars: A 24-Month Randomized Clinical Trial

Overview

This clinical study aims to compare the clinical performance of two different fissure sealant materials-glass ionomer and resin-based-when applied to newly erupted permanent first molars in children. The study evaluates which material provides better retention, marginal adaptation, and protection against dental caries over a 24-month period.

This randomized, split-mouth, clinical study was designed to compare the clinical effectiveness of two different fissure sealant materials-glass ionomer-based (Fuji Triage™ Capsule) and moisture-tolerant resin-based (UltraSeal XT® Hydro)-in newly erupted permanent first molars in children aged 6-7 years. The study evaluates the retention rates, marginal adaptation, marginal discoloration, and the ability of each material to prevent dental caries over a 24-month follow-up period. A total of 70 teeth from 35 children were sealed using a split-mouth design, ensuring that each participant received both types of sealants on contralateral molars. Clinical evaluations were performed at 1, 6, 12, 18, and 24 months using modified United States Public Health Service (USPHS) criteria. The goal of the study is to determine whether the moisture-tolerant resin-based material offers a clinical advantage in terms of sealant retention and caries prevention in a partially erupted, moisture-challenged clinical environment.
