Abstract

Aim

The aim of this study was to determine and compare the shear bond strength of three different pits and fissure sealants to enamel namely, Delton, Clinpro and Z350 Filtek flowable composite.

Materials and methods

Ninety permanent molars were divided into three groups of 30 each. Their proximal surfaces were prepared and stored in 37°C ± 5°C normal saline for 24 hours. Sealant buttons were prepared. The specimens were tested in a shear mode (Lloyds LR100K) at a crosshead speed of 0.5 mm/min. The mean and standard deviations were subjected to an analysis of variance.

Results

The mean shear bond strength of samples of Delton was 10.33 MPa; Clinpro was 8.51 MPa and Z350 Filtek flowable was 12.17 MPa. The mean strength of Delton was significantly higher as compared to Clinpro whereas the mean strength of Z350 Filtek was significantly higher as compared to Delton and Clinpro (Student t-test, p < 0.001).

Conclusion

Z350 Filtek flowable composite had maximum shear bond strength than Delton FS sealant followed by Clinpro sealant.

Clinical significance

In this study, we compare the bond strength of three pits and fissure sealant, Clinpro yielded lower bond strength than Delton. This outcome can be described due to the presence of fillers in Delton, since these particles increase the resistance of the material to abrasion and also increase the mechanical resistance of the material.
