Preventive Resin Restoration Outcomes Indications for Preventive resin restoration Preventive resin restoration procedure and Follow up Recall indications for fissure sealants Pit and fissure surfaces of sound teeth judged to be at risk for dental caries Incipient, non-cavitated carious lesions to inhibit lesion progression – discolouration confined to the size of a pit or fissure or may extend to the cusp inclines  When and where ?? restoring young permanent teeth Diagnosis – stained fissure is a carious lesion into dentine – areas of the tooth not bearing occlusal loads REMEMBER – If the lesion is more extensive, the clinician should consider a composite or amalgam class I restoration.  Principle Treatment and prevention – only minimal tooth preparation for caries removal but also have adjacent susceptible fissures sealed – advocated for carefully selected non–stress- bearing areas to minimize anatomic wear.  Step 1 Administer local analgesia, after application of topical anaesthetic paste at the injection site  Step 2 Place rubber dam reexamined so that the extent of the caries process can be determined Dry brush cleaning  Step 3 Caries excavation – high-speed small bur – only enough enamel to gain access – access must by wide enough to ensure that the operator can remove caries from the peripheral tissue  complete caries removal The preparation, which should not extend to the occlusal contact  Step 4 ONLY IF EXCAVATION IS VERY CLOSE TO PULP Line the cavity with calcium hydroxide and followed by GIC  Step 5 Etch and wash  Step 6 Dry and Bond  Step 7 Composite  Step 8 Sealants to adjacent or remaining fissures  Step 9 Check the occlusion and adjust if necessary  Step 10 recall appointments Repair the sealant  A small-particle diamond rotary instrument can be used to remove excess sealant and ensure centric stops on the enamel  flowable composite systems are gaining in popularity
