Selantes de fossas e fissuras em dentes decíduos: estudo retrospectivo

Abstract

The purpose of this retrospective study was to evaluate the indications, retention and efficacy of sealant of pits and fissures in deciduous teeth. The following data were taken from dental records of children who were treated at pediatric dentistry clinics: age and sex; sealed tooth; inicial condition of the tooth surface (healthy or with enamel carious lesion), before sealing; material used; need for sealing reapplication (number of times) or restoration; classification of the child regarding the risk of caries (low, moderate and high) at the time of the indication; total retention and efficacy of the sealant ( success x failure); 55 charts of children of both sexes, with average age of six years and six months were evaluated. The results showed that the sealant was performed on 251 teeth, 63.75% of which were second molars and 93.63% with a healthy surface. The most used material was resin-modified glass ionomer cement (67.33%). The need for reapplication ranged from one to four times. According to the risk classification, 36 (65.46%), 10 (18.18%) and 9 (16.36%) children were low, moderate and high risk, respectively. The total retention rate was 47.81%. Of the total sealed teeth, 90.04% teeth did not develop carious lesions. The Qui-Quadrado test showed statistically significant differences between the frequencies compared (success x failure) (p <0.05). It was concluded that the sealant was more indicated for second molars, healthy surfaces and in children of low risk for caries. The sealants exhibited satisfactory retention and high efficacy.
