Avalia o do selamento de les es de cárie comparado à restaura o com resina composta em dentes decíduos

The aim of this in vivo study was to verify the effect of pit and fissure sealants tocontrol the initial caries injuries compared with the restorative treatment. Twenty deciduousteeth had been selected and divided in: group I resinous sealant and group II restoration withcomposite resin, after the partial removal of the carious dentin. After 12 months of attendance8 teeth were excluded of the research. The results showed that 83% of the deciduous molars from group I presented complete material retention and in 100% of cases a non-progression ofinjury was observed. For group II, complete material retention was observed in 100% of theteeth and in 100% of the cases there were non-progression of the injury. We conclude that thepit and fissures sealants constitute a more conservative treatment then restoration, propitiatingthe stoppage of injuries of initial caries lesions and preservation of the dental structure.
