Introduction

Pits and Fissures are the enamel

faults;narrow

shafts and cracks.

Cement which is introduced into unprepared occlusal pits & fissures of caries susceptible teeth forming a protective layer against action of acid producing bacteria.Slide3

Materials used as Sealants

Polyurethanes

Cyanoacrylates

Methylmethacrylate

BISGMA

Glass

IonomerSlide4

Procedure of Application

Surface Cleanliness of Tooth

To remove plaque and debris from pits and fissures of tooth.

It can be carried out by pumiceSlide5

Isolate and Dry the Tooth

Rubber dam provides the best isolation

If rubber dam application is not

possible,use

any means to keep the tooth away from saliva.Slide6

Acid Etching

Removes organic material and debris from surface

Produce micro-pores into which monomer penetrates

30-50% Ortho-phosphoric acid applied for 30-60 seconds.Slide7

Rinse,Dry

and Isolate the Tooth

Tooth should be rinsed for 30 seconds

Dry the tooth with compressed air

Tooth is dried until it has chalky white appearance.

Avoid salivary contaminationSlide8

Material Application

The sealant is then applied to the tooth according to manufacturer’s directions.

Material is polymerizedSlide9

Evaluate the Sealant and Check Occlusion

The sealant should be evaluated visually and tactically.

Take explorer and attempt to dislodge it.

If there are any deficiencies, add more material.

Check for occlusal high spots and correct themSlide10

Indications

It is indicated when deep occlusal fissures are present.

Provided to patients with continuing caries risk or belonging to non-Fluoride area.

Children with mental impairment.Slide11

Contra-indications

It is not indicated in patients with caries on other surface of tooth

H

aving large occlusal restoration already.

Shallow pits and fissures

Partially erupted tooth due to isolation problem

Uncooperative child due to isolation problem.Slide12
