ABSTRACT
AIM:
The aim of the present study was to compare the shear bond strength and marginal sealing ability of self-adhering flow-able composite and conventional fissure sealant. MATERIALS ANDMETHODS:
The samples consisted of 30 healthy premolar teeth which were extracted due to orthodontic reasons and randomly divided into two groups of 15, i.e., group I (Fissurit F) and group II (Dyad Flow). Shear bond strength and marginal sealing ability of both the groups were evaluated in Statistical Package for the Social Sciences (SPSS) version 16.RESULTS:
The mean shear bond strength of Dyad Flow (group II) was found to be 1.4 ± 0.87 MPa and in Fissurit F (group I), it was 1.3 ± 1.4 MPa. Differences between the groups were statistically significant. In group II, 53.3% of specimens demonstrated score 0; 33.3% showed score 1; and 13.3% showed score 2. In group I, scores 0 and 1 showed 33.3% of dye penetration respectively. Scores 2 and 3 demonstrated 26.6 and 6.6% of dye penetration respectively. But there was no significant difference between both the sealant groups.CONCLUSION:
The present study concluded that self-adhering flowable composite was found to have better shear bond strength and marginal sealing ability than conventional fissure sealant. CLINICALSIGNIFICANCE:
Self-adhering flowable composite can be effectively used in pediatric patients in whom isolation is difficult and exclusion of bonding agent leads to decrease in time consumption.Palabras clave
