Equipment & SuppliesSlide4
Teeth must have deep pits and fissures & be sufficiently erupted
Select the TeethSlide5
Clean the Enamel
Cleanse the tooth with a fluoride free pumice paste to remove plaque and debris from the
occlusal
surface & rinse and dry the toothSlide6
Isolate the teeth

What happens when effective isolation is not achieved?Slide10
Etch the Enamel
Acid etchant helps the sealant bond to enamel
Etching toothSlide11
Use the syringe tip to apply a generous amount of acid etchant to tooth surface being sealed, extending slightly beyond the anticipated margin of the sealant
Apply etch for a minimum of 15 seconds but no longer than 60 seconds
Suction etchant before rinsing
Rinse with air-water syringe and suction to remove remaining etch
Air dry tooth until tooth surface appears chalky whiteDo not allow etched surface to become contaminatedApplication of Acid EtchantSlide12
Etchant AgentPrecautions
What are some etchant precautions?Slide13
Avoid etching gingiva, lips, swallowing, etc… though isolation & proper application technique
PrecautionsSlide14
Slowly apply a thin layer of sealant material using the syringe tip or a brushUse an explorer or cotton tipped applicator to increase flow of sealant into pits and fissures and eliminate possible bubbles
Light cure for 20 seconds holding tip of light as closely as possible to the sealant without actually touching sealant
Apply Sealant MaterialSlide15
Sealant Material Precautions
What are some
seal
ant
precautions?Slide16
Contraindications
Allergies to materialSlide17
Use mouth mirror to check the shine and coverage of the sealantUse explorer to gently trace the sealant for complete coverage and voids
If the sealant has not been contaminated, additional sealant may be placed to fill in voids
If sealant had been contaminated, re-etch 5 seconds, rinse and dry before placing additional sealant material
Check SealantSlide18
Check interproximal
areas with dental floss
Check occlusion using articulating paper and adjust if required. If bite is high, unfilled sealant will wear down in days or weeks, filled sealant material can be adjusted using a stone or bur.
Provide the patient with postoperative instructions
Document the procedure in the patients chart.Complete Sealant Application
