Evaluating Different Protective Coating for Healthy molars In Children: A Clinical Study

INTERVENTION: Intervention1: GC FUJI 7 Glass ionomer based pit and fissure sealant: Applied to the occlusal pits and fissures of one randomly allocated permanent first molar according to the manufacturers instructions after cavity cleaning, conditioning, mixing, placement, and initial protection. Control Intervention1: Kidz‐e bioactive pit and fissure sealant: Applied to the occlusal pits and fissures of one randomly allocated permanent first molar according to the manufacturers instructions after tooth cleaning, isolation, etching, rinsing, drying, sealant placement, and light curing. Control Intervention2: 3M ESPE Resin based pit and fissure sealant: Applied to the occlusal pits and fissures of one randomly allocated permanent first molar according to the manufacturers instructions following the standard acid‐etch technique and light curing. Control Intervention3: Shofu beautisealant GIOMER based pit and Fissure sealant: Applied to the occlusal pits and fissures of one randomly allocated permanent first molar according to the manufacturers instructions using the recommended self‐etch primer and light‐curing protocol. CONDITION: Health Condition 1: K025‐ Dental caries on pit and fissure surface PRIMARY OUTCOME: Retention of pit and fissure sealant materials using Cvar and Ryge CriteriaTimepoint: At 1 month, 3 months , 6 months, 12 months SECONDARY OUTCOME: Caries Inhibition potential using Cvar And Ryge CriteriaTimepoint: 1, 3, 6, 9 MONTHS Color change around the sealant using the Cvar & Ryge criteriaTimepoint: 1, 3, 6, 9 MONTHS Marginal adaptation using the Cvar ; and Ryge criteriaTimepoint: 1, 3, 6, 9 MONTHS Surface roughness of sealant using the Cvar & Ryge criteriaTimepoint: 1, 3, 6, 9 MONTHS INCLUSION CRITERIA: 1. Normal healthy children aged 8‐11 years. 2. Presence of all four caries‐free completely erupted permanent first molars with fissures either intact, deep or retentive which are stained or calcified but not carious. 3. Children who were not undergoing any other preventive dental health programme. 4. Availability for the duration of study. 5.Satisfactory dental care performed at home. 6. Patient cooperation and acceptance of the treatment.
