Abstract

Objectives: The aim of this research is to evaluate the retention of sealants of resin and resin-modified ionomeric glass pits and fissures, on first permanent molars of special patients. Material and Methods: The sample was comprised by 32 children. The ages were between 7 and 18 years. The sealing procedure was made with the relative isolation of the molars to be sealed, through the use of cotton rolls. Two molars were sealed with Clinpro Sealant 3M Dental and the others with Vitremer. Checking of the sealants was made after 3 and 6 months of their placement, evaluating with 3 values: TR: Totally Restrained; PR: Partially Restrained; and CL: Completely Lost. Results: 67.18% of the resinous sealants, and 70.31% of the glass ionomer sealants were successful after three months. After six months, 57.81% of the resin-based sealants and 51.56% of the glass ionomer sealants were successful. When performing the Chi-square statistical analysis (P<0.05) no statistical significance was observed after 6 months. Conclusions: The retention of the resin sealant was similar to that of the glass ionomer cement at the end of six months and the retention of sealants on maxillary teeth was higher than on mandibular teeth. Key words:Sealant, glass ionomer, retention, caries, special needs.

Highlights

According to the World Health Organization, there are over a billion people in the world living with some kind of disability
Many systemic diseases, disabling conditions, and medical treatments may reduce the caries resistance of the patient. These patients are more prone to suffering from caries due to motor coordination problems that hinder or difficult mouth hygiene, lack of care on the side of the people that look after them, ingestion of a big number a medications that favor xerostomy, and excessively bland diets [1]
Besides the evaluation of retention based on the aforementioned criteria [present, partially present, and lost], the data was separated in two groups [success, failure], where only sealants found to be completely present were considered a success, and the other two criteria were considered failures

Summary

Introduction

According to the World Health Organization, there are over a billion people in the world living with some kind of disability. Many systemic diseases, disabling conditions, and medical treatments may reduce the caries resistance of the patient. These patients are more prone to suffering from caries due to motor coordination problems that hinder or difficult mouth hygiene, lack of care on the side of the people that look after them, ingestion of a big number a medications that favor xerostomy, and excessively bland diets [1]. The use of sealants on pits and fissures is still one of the most widely accepted methods by the new cavityprevention programs, as 80% of them develop in the pits and fissures of the tooth, due to the favorable conditions for the accumulation of plaque, and because it is a place in which fluoride cannot act. Sealants must be placed between 1 – 1.5 years post eruption, as this is the period considered to be critical, because the enamel is not come551
