Abstract:

In an in vitro experimental study, an occlusal fissure with 40 permanent human teeth was cleaned with a dry, sharp bristle brush and prophylaxis toothpaste using a low-speed handpiece and rinsed with water and dried by pressure without oil for the 20s. Half of the cavities are filled with low viscosity Resin sealant followed by light treatment for 20 seconds. According to the manufacturer's instructions, the remaining cavities were sealed with Resin Modified glass ionomer sealant, and the light was treated for 40 seconds. These teeth were subjected to microleakage testing, followed by SEM testing of the enamel-sealant optical connector. No microleakage (grade 0) was found in 17 cases (85.0%) in the sealed by resin-modified glass ionomer sealant and 16 cases (80.0%) in the light-cured resin sealant. In the Resin modified glass ionomer sealant, minor leakage was detected in 3 cases (Grade 1 = 2 & Grade 2 = 1), and in the resin sealant, minor leaks were detected in 4 (Grade 1 = 3 ). & Grade-2 = 1) cases. In conclusion, the recycled glass resin ionomer sealant is slightly better than the light-cured resin sealant.
