Fissure Sealants are resin-based materials that are applied to the pits and fissures in tooth in preventing tooth cavities. The success of the fissure sealants depends on degree of binding with tooth surface and isolating capacity the pit and fissures from the mouth environment. The narrow width and irregular depth of the fissures creates an ideal milieu for the accumulation of acid producing bacteria. The cleaning function of saliva are insufficient for the pits and fissures in grinders. Besides the diameter of bristles of toothbrush are too big for cleaning the fissure surface. Fissure sealants act as a physical barrier for the acids produced in bacteria plaque. While the application of the traditional fissure sealants is providing an accetable protection in cavity process; it is also a non-invasive technic that is protecting tooth integrity. Lately the application of the protective and primary care treatmants has become considerably rare and it began to be percieved as insignificant by the dentists. The purpose of our study is to extend the use of fissure sealants by the dentists with creating a better understanding on the importance of fissure sealants, and also explaining the application areas clearly.
