Abstract

Aim: The aim of the study was to compare and evaluate tensile bond strengths of fluoride containing resin-based sealant (Fissurit Fx) with that of Aegis with Amorphous Calcium Phosphate (ACP) sealant as well as compare effect of preparation techniques with fissurotomy tapering bur or endosonic tip. Materials and Methods: Maxillary first premolar teeth were extracted for orthodontic purposes and samples were embedded in blocks of self-curing acrylic resin. Preparations of fissures were done using fissurotomy bur STF and endosonic tips. SS wires of 21 gauges were embedded into sealant and cured. Samples were thermocycled for a dwell time between 5°C and 55°C to correlate with maximum temperature range measured in vivo. The selected teeth were distributed into 4 groups of 15 teeth each. Group 1 (Aegis with ACP with fissurotomy bur), Group 2 (Aegis with ACP with endosonic tips), Group 3 (Fissurit fx with endosonic tips), and Group 4 (Fissurit Fx with f issurotomy bur). The specimens were put to test under 5555 instron machine. The statistical analysis was done using the one-way ANOVA test. Results: Tensile bond strength was significantly greater for Aegis ACP sealant as compared to fissurit FX sealant. Tensile bond strength of Aegis ACP sealant using endosonic tips was significantly greater than Aegis ACP sealant using fissurotomy bur. Conclusion: Smart material Aegis with ACP pit and fissure sealant proves to be a better alternative to Fissurit Fx sealant in terms of retention and remineralization of enamel.
