Abstract
It is commonly known that pit and fissure sealants are efficient at preventing occlusal caries. Therefore, it is of interest to assess two distinct pit and fissure sealants' marginal sealing capabilities. A total of forty human premolar teeth were split into two sealant groups: fissuritfx and ultrasealXTplus sealant (group i). The samples were submerged in a 2% methylene blue solution for a full day following the application of the sealant. An optical stereomicroscope was used to examine the sectioned samples. Better performance was found with ultrasealXT plus compared to Fissurit FX.
