Abstract

Introduction: Fissure sealant is used to reduce the incidence of occlusal decays. Recently, resin substances have been significantly developed, one of which is infiltrating resin Icon .This study aimed to compare fissure sealant from 3M ESPE and infiltrating resin in terms of microleakage. Materials and Methods: This experimental study was conducted on 40 extracted premolars with no decay and crack. These teeth were divided into two groups. The striae of occlusal surfaces of the teeth were covered by fissure sealant from 3M ESPE and infiltrating Icon resin according to the manufacturer’s recommendation. Thereafter, the teeth were thermocycled 500 times between 5°C to 55°C and finally placed in distilled water. The apex of all the teeth and divergence of the roots were sealed by sealing wax. The whole surfaces of dental root and crown were coated with two layers of nail varnish 1 mm from the sealant margin. The teeth were put in 0.5 volatile fuchsine at the temperature of 37°C to allow the coloring agent to penetrate to possible gaps between enamel and sealant. Then, the teeth were washed and cut off parallel to linear axis. The samples were studied in order to assess the amount of microleakage under the stereomicroscope with 36× magnification. The leakage was scored from 0 to 3. Data analysis was performed using Mann-Whitney U test. Results: There was no significant difference between fissure sealant from 3M ESPE and infiltrating resin in terms of microleakage (P=0.512). Conclusion: According to the results, the use of fissure sealant was more cost-effective and less time-consuming than the Icon material.
