Sealing noncarious pits and fissures
Rendering the tooth and the restoration interface caries resistant after tooth repair
Easy handling properties
Cost resonable

3. Clinical use of GI Sealant Luting cement Orthodontic bracket adhesive
Cavity liner/base

4. Polymerization

5. Fluoride release

6. Disadvantage
Lower wear resistance and physical properties compare to composite
Moisture sensitive remain
Unstable color
