Evaluating the clinical effects of light cure Dyractflow in pit and fissure enamel-plasty sealant technique during 3 years

Objective To evaluate the clinical effect of light cure Dyractflow (LCDF) in pit and fissure enamel-plasty sealant technique (EST). Methods A total of 400 first permanent molars in 200 patients aged from 6 to 10 years were treated with LCDF in occlusal pit and fissure enamel-plasty sealant technique. The opposite permanent teeth treated with LCDF in occlusal pit and fissure conventional sealant technique (CST) were employed as the controls. The patients were followed up for 3 years. Results Follow-up for 3 years showed that there was no significant difference in preservation rate between the EST and the CST groups in the first year, but in 2-3 years, there was significant difference in preservation rate (P0.01) and in caries prevalence rate (P0.01) between the EST and the CST groups. Conclusion LCDF can be used as pit and fissure sealant to prevent caries. EST is better than CST in clinical application.
