Abstract

Introduction: FISSURE SEALANT therapy is one of the effective methods to prevent dental caries but because of SALIVA CONTAMINATION, this method is accompanied by some problems. The aim of this study was to investigate the micro leakage of FISSURE SEALANT in isolated state in different time periods of contamination with saliva.Materials & Methods: In this in vitro experimental study, Ninety-two extracted human premolars were investigated in this study. A vertical groove was prepared on the buccal surface of each tooth and then the teeth were divided into four groups with 23 teeth in each group. Sealant therapy was done in isolated condition in the first group. The groove of each tooth in the second group was contaminated with saliva for 5s after washing up acid and then was dried and filled by FISSURE SEALANT. The groove of each tooth in the third group was contaminated with saliva for 10s after washing up acid and then was dried and filled by FISSURE SEALANT. This process was done for the forth group as well except for the contamination time with saliva which was 15 seconds in this group. Next, the teeth were undergone thermo cycling for 2000 cycles. After that, the teeth were immersed in a 0.5% basic fuchsine solution for 24h. Finally, the teeth were sectioned longitudinally in buccallingual direction and were examined and a ranked scale was used to score dye penetration. Mann-Whitney and Kruskal-Wallis tests were used for data analysis through SPSS 15 software.Results: In this study, Group 1 with 60.9% grade 1 leakage (no leakage) showed better results than other groups but statistical analysis did not demonstrate any significant differences in the degree of micro leakage of sealants between isolated state and 5 second contamination state (P=0.8).Conclusion: According to the results of this study, SALIVA CONTAMINATION after washing up acid for 5s did not induce any further micro leakage.
