Abstract : Background Icon has emerged recently as a new material in dentistry with a new concept and technique in conservatively restore non-cavitated carious lesion. Aim To evaluate penetration depth and micro-leakage of resin infiltration when used to prevent non-cavitated white lesions progression in the fissure system of permanent teeth compared to conventional sealant. Material & Methods Freshly extracted permanent teeth with artificially produced non-cavitated white spot lesions (N = 60) were randomly allocated to two groups: group I (experimental) was infiltrated with Icon resin infiltrate and group II (control) received Helioseal F resin-based sealant. Thirty teeth were allocated for penetration test where the restorative materials were mixed with a fluorescent dye (eosin H) before applying and light curing then the roots were amputated and 3 bucco-palatal microscopic sections were obtained from each tooth. The microscopic sections were dipped in hydrogen peroxide for 18 h to remove unattached dye particles then in 0.001mg of sodium fluorescence diluted in 50 % ethanol. Material penetration depth was assessed through confocal microscope. Thirty teeth (15 from each group) underwent micro-leakage test. Teeth were thermo-cycled then immersed into 50% AgNo3 solution for 3 h and were set under ultraviolet light for 8h subsequently. The presence of micro-leakage was evaluated using Micro CT; where sliver nitrate presence between the material and the tooth surface was an indicative of micro-leakage. Mann-Whitney test was used to measure the difference between the two groups in each test. Results The mean material penetration value in teeth treated with Icon (104.8571 ± 7.63360 µm) was significantly higher than teeth treated with Helioseal F (5.3158 ± 3.83825 µm) (p < 0.001). The mean micro-leakage value in demineralized enamel treated with Helioseal F (0.2238 ± 0.12561) was significantly greater when compared to Icon (0.0119 ± 0.0097) (p < 0.001). Conclusion Icon can be used as an alternative to fissure sealants for sealing the initial non-cavitated fissure lesions in permanent teeth.
