Abstract

The aim of this study was to evaluate and compare for 24 months, the retention and surface characteristics of two pit-and-fissure sealants: Helioseal Clear and Helioseal F (Ivoclar Vivadent). The correlation between the different stages of eruption and sealant retention was also verified. Fifty children aged 6 to 8 years participated in the study, totalizing 153 teeth divided into two groups: HC (Helioseal Clear) and HF (Helioseal F). After 6, 12, 18 and 24 months, a clinical examination was performed by previously calibrated examiners. The surface characteristics and the retention of the sealants (modified RYGE & SNYDER criteria) were assessed. Analyzing the occlusal surface, HC exhibited a statistically significant higher retention at 12 (p=0.0345) and 24 months (p=0.0076). Concerning the surface characteristics, only the superficial discoloration of HC was smaller than HF, during the entire studied period. For all the other characteristics, the results of the Mann-Whitney test were highly significant at different periods (p=0.0000 to 0.0421). The frequency of air bubbles within the sealant surfaces, determined by Chi-square test, was significantly higher in HF (p=0.000:12 and 18 months to p=0.002: 6 and 24 months). HC sealant material exhibited the best performance regarding the retention and surface characteristics on the occlusal surface.

Highlights

The occlusal surfaces of the permanent molars represent only 12.5% of all tooth surfaces [1,2,3], they are highly susceptible to caries [4,5,6,7], which accounts for more than two thirds of the total of lesions in children [1]
Caries prevalence among children and adolescents seemed to decline in industrialized countries, but caries rate in occlusal surfaces is still high among this population [12,17]
50 children had sealants distributed into two groups: Helioseal Clear® (HC)

Summary

Introduction

The occlusal surfaces of the permanent molars represent only 12.5% of all tooth surfaces [1,2,3], they are highly susceptible to caries [4,5,6,7], which accounts for more than two thirds of the total of lesions in children [1].Sealing of pits and fissures is one of the most efficient methods to prevent occlusal caries [1,3,8,9,10,11,12,13,14,15]. The efficacy of resin-based sealants in preventing caries lesion has been associated with their retention [2,4,5,16], which decreases over time This situation seems to be related to the prevalence of caries in the population. Caries prevalence among children and adolescents seemed to decline in industrialized countries, but caries rate in occlusal surfaces is still high among this population [12,17]. These differences may be due to the fluoridation of public water supply, use of fluoride dentifrices, and other factors. It is not known whether the last sealant generation containing fluoride has added benefits to caries prevention [2]
