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 (P
