Retention Rate and Caries Preventive Effect of Preheated Flowable Resin Composite Used as a Pit and Fissure Sealant

Retention rate and caries preventive effect of preheated flowable resin composite used as a pit and fissure sealant versus conventional resin-based fissure sealant in patients with permanent molars with deep pit and fissure over one year follow up. A randomized clinical trial

Inclusion Criteria:participant:Young adults (16_22y)Patients who have existing pits and fissures that are anatomically deep and caries susceptible.TeethPermanent molars teeth without any caries and cavitation. (Azarpazhooh & Main 2008)Permanent molar teeth that have deep pit and fissure morphology, with "sticky" fissures.Permanent molar teeth with stained grooves.Stained pits and fissures with minimum decalcification of opacification and no softness at the base of the fissure (ICDAS 1 and 2).-Exclusion Criteria:participant:Uncooperative behavior, limits the use of sealants due to hampering of adequate field or isolation techniques throughout the procedure.Patients allergic to sealant material.Patient with history of medical disease, drug therapies or any other serious relevant problem.Teeth:An individual with no previous caries experience and well coalesced pits and fissuresPartially erupted teeth.Teeth with cavitation or caries of the dentin.A large restoration is present on occlusal surface.If pits and fissures are self-cleansable.Teeth with dental fluorosis, hypocalcification or hypercalcification
