BBBBOVER A PERIOD OF TIME PIT AND FISSURE SEALANTS HAVE BEEN PROVED TO BE EFFECTIVE IN
PREVENTING INCIPIENT PIT & FISSURE LESIONS AND MAINTAINING ORAL PROPHYLAXIS
STEP 1-
POLISHING THE TOOTH SURFACE WITH
PUMICE SLURRY & ISOLATION
CLASSIFICATION (MITCHEL & GORDON)
BASED ON CURING METHOD:
-1ST GEN (UV LIGHT 350nm)
-2ND GEN (SELF CURED)
-3RD GEN (VISIBLE LIGHT 430nm)
-4th GEN (FLUORIDE RELEASING)
BASED ON PRESENCE OF FILLERS
-UNFILLED (BETTER FLOW)
-SEMIFILLED (BETTER STRENGTH & WEAR
RESISTANCE)
INDICATIONS
-NEWLY ERUPTED 1ST MOLAR AND
PERMANENT MOLARS AND
PREMOLARS
-STAINED PIT & FISSURES WITH
MINIMUM DEMINERALIZATION &
SOFTENING OF BASE
-IN PATIENTS WITH CONTINUING
CARIOUS RISK WHO HAVE FISSURE
CARIES JUST INTO DENTIN.
STEP 2-
ACID ETCHING (37% ORTHO-
PHOSPHORIC ACID), RINSE & DRY THE
TOOTH
SUMMARY- THE CARIOSTATIC PROPERTY OF SEALANTS ARE ATTRIBUTED TO PHYSICAL OBSTRUCTION OF PITS &FISSURES THUS PREVENTING ENTRY OF
FERMENTABLE CARBOHYDRATES AND PRODUCTION OF ORGANIC ACIDS IN CARIOGENIC CONCENTRATION HENCE EFFECTIVELY INHIBITING DENTAL
CARIES.
