Abstract：AIM:to evaluate the effects of sealing materials with different content of fillers and fissure surface treatments on the pit and fissure sealing.METHODS:A total of 600 first molar teeth of 150 children age 6 to 9 years old were selected,and randomly divided into 3 groups to get pit and fissure sealing with ClinproTM,Helioseal F,Fissurit F.This split-mouth design was conducted in this study.The first molars were cleaned with little brush on the right side of mouth,and P1 ultrasonic tip was used to clean the first molars on the other side.The sealant expulsion rates and caries prevalence rates were compared 6 and 12 months after treatments.RESULTS:When the sealant was the same,at 6 months after treatment,the expulsion rate of Fissurit F sealant in the brush cleaning group was significantly higher than that in ultrasonic cleaning group(P＜0.05),at 12 months after treatment,the expulsion rates of ClinproTM and Fissurit F sealant in the brush cleaning group were significantly higher than that in ultrasonic cleaning group,respectively(P＜0.05).When the fissure surface treatment was the same,at 6 months after treatment,the expulsion rate of Helioseal F sealant in the brushing cleaning group was the lowest,which was significantly lower than that of ClinproTM sealant(P＜0.05),and the expulsion rate of Fissurit F sealant in the ultrasonic cleaning group was the lowest,which was significantly lower than that of ClinproTM sealant.Otherwise,Furthermore,the caries prevalence rate for the three sealants was lower in ultrasonic cleaning group than that in brush cleaning group,but there was no statistical difference between the two groups,respectively(P＞0.05).CONCLUSION:The use of ultrasonic tip to clean the pits and fissure shows more effective than little brush in the process of pit and fissure sealing,and on this basis,the sealants with high filler content show the better sealing effect,which is recommended for clinical application.
