Abstract Objective To explore the influence of saliva contamination on microleakage of pit and fissure sealant.Methods A total of 122 premolars extracted to orthodontic need from January 2018 to April 2020 in Guangdong Yanling Hospital were selected as subjects.They were divided into group A and group B according to the random number table method,with 61 teeth in each group.There was no saliva contamination in group A and saliva contamination in group B,and both groups had their socket sulci treated using an enamel forming procedure.Microleakage was compared between the two groups.Results The microleakage score of group A was mostly 0 points,followed by 1 point.In group B,the microleakage score was mostly 3 points,followed by 2 points,1 point,and no 0 points.The microleakage score in group B was(13.74±To 1.15)points,which was higher than that of group A(1.11±0.08)points,and the difference was statistically significant(P＜0.05).Conclusion Saliva contamination can increase the microleakage of the pit and fissure sealant.It is necessary to strengthen the cleanliness of the tooth surface before clinical treatment to reduce the occurrence of microleakage of the pit and fissure sealant.

Key words： Pit and fissure sealant Saliva contamination Microleakage Enamelplasty
