Abstract

Objective: To compare the retention and superficial characteristics between a new resin-modified glass ionomer sealant and resin sealant. In addition, the teeth sealed were compared to partially erupted first molars (control group) without sealing in relation to the incidence of dental caries. Material and Methods: Initially, 31 children aged 6-8 years participated in this study. The study children showed caries history, but had at least two healthy first molars. A total of 114 teeth were randomly divided into three groups: Clinpro (n=36), Fluroshield (n=38), and control (n=40). The two sealants were applied under relative isolation after previous prophylaxis and enamel etching with phosphoric acid 35% (15s). Clinical evaluation was performed by two calibrated examiners. They evaluated the retention and surface characteristics of the occlusal surface. Results: Fluroshield® showed significantly greater retention than ClinproTM Varnish® XT (p=0.002). However, the performance analysis of the success and failure of retention presented no significant difference between the materials (p=0.141). Concerning to the surface characteristics, Fluroshield performed better than Clinpro after analyzing the marginal deterioration, marginal discoloration, and superficial discoloration (p<0.05). The surface texture of the materials under study was similar (p=0.071). Sealed groups (Clinpro=Fluroshield) showed similar performance in the prevention of dental caries, which was significantly lower than that of control group (p=0.001). Conclusion: Both sealants, Fluroshield® and Clinpro TM Varnish® XT were effective in preventing caries lesion within 6 months, although Fluroshield sealant showed better clinical retention.

Highlights

The occlusal surface of posterior teeth is the most susceptible to plaque accumulation and bacterial proliferation because of the specific anatomical morphology [1]
The most used and studied pit and fissure sealant material is that based on Bis-GMA [6]
With the development and improvement of glass ionomer cements (GIC), many authors have proposed its use as pit and fissure sealant aiming at obtaining further preventive effects because GICs are caries inhibitors due to the fluoride inside the composition

Summary

Introduction

The occlusal surface of posterior teeth is the most susceptible to plaque accumulation and bacterial proliferation because of the specific anatomical morphology [1]. Pit and fissure sealing is one of the most used measures to prevent occlusal caries, since it is a safe, viable, and effective method [3,4,5]. With the development and improvement of glass ionomer cements (GIC), many authors have proposed its use as pit and fissure sealant aiming at obtaining further preventive effects because GICs are caries inhibitors due to the fluoride inside the composition. Such property is interesting for permanent first molars, especially during the period of eruption [4,7,8,9,10]
