The purpose of this study was to determine and compare the shear bond strength of 4 fissure sealant systems (Dyract Seal, Concise, Visio-Seal, Helioseal) to enamel using conventional etch and self-etching primer (Prompt L Pop).
56 newly extracted noncarious 1st permanent molars were used and embedded in a Teflon mold. Mesial surfaces were exposed to a flattened area of enamel and then dried and washed. The teeth were divided into 8 groups, each consisting of 7 specimens stored in 37 C distilled water for 24 hours. Then specimens were tested in a shear mode at a crosshead speed of .5mm/minute. The mean and standard deviations were subjected to an analysis of variance.
Results: The average bond strengths using the L pop were 1. Dyract Seal 20.61 Mpa, 2. Concise 23.42 MPa 3. Visio- Seal 2.94 MpA and 4. Helioseal 1.83Mpa These values were higher than and statistically different from those of Dryract Seal 10.18 Mpa and Concise 9.14Mpa when the conventional etch system was used.
Conclusion: The bond strengths of L pop in conjunction with Dyract Seal and Concise fissure sealant materials, exceeded those of convention.
