Conditions

Previously untreated fully eruption of permanent molars with sound surface or carious lesion (ICDAS score 2&#45

Interventions

All pit and fissure surfaces are etched with 3Mâ„¢ ESPEâ„¢ Scotchbondâ„¢ Universal Etchant contains 37% by weight phosphoric acid for 30 seconds&#44

then thoroughly rinse the teeth with air/water spray to remove etchant&#44

drying until the etched surfaces appear chalky&#45

white&#44

apply sealant (Helioseal clear) with microbrush to all surfaces&#44

then use the explorer along the groove to enhance sealant penetration and also remove the bubbles&#44

and light&#45

cured for 20 seconds per surface. After that the sealants are checked by explorer for retention and any defects. The occlusion will be checked with articulating paper and adjusting if needed. If any o
