of caries in permanent posterior teeth and 44% of caries in primary teeth. Dental caries can easily start on the biting surfaces of posterior teeth, as well as in pits, fissures, and enamel defects. Pits and fissures also have thin enamel at their base [2]. Furthermore, standard oral hygiene steps such as tooth brushing are ineffective in removing plaque that has accumulated in these regions. Because of their morphological complexity, pits and fissures on the occlusal surfaces of posterior teeth are more vulnerable to caries growth than smooth surfaces, making dental hygiene more difficult and contributing to increased plaque accumulation. As compared to the enamel on smooth surfaces, the enamel in pits
