Fillings And Sealants
When And Why Fillings Are Required?
Fillings are materials that are used to replace the lost tooth surface due to the following reasons
- Cavities formed because of decay Excessive brushing in forward and backward motion on the
- sides of the tooth surface leads to enamel loss forms a deep groove that often leads to a sensitivity
- Chipped of teeth due to trauma
- Deep pits and fissures on the tooth surface
- Tooth surface abnormalities Eg-flurosis (dark discolored patches and pits)
Dental decay left out food on the tooth surface for a longer time leading to the accumulation of microorganisms that releases an acidic substance which causes demineralisation on the tooth surface leading to a cavity.
The depth of the cavity determines the treatment pattern.
Fillings can be done only when the cavity doesn’t involve the middle portion of the tooth which has blood and nerve supply.
Good clinical evaluation and thorough X-ray examination will be helpful in determining the depth of the cavity.
Different Types Of Materials Used
- Cements like zinc oxide Eugenol,zinc phosphate and glass ionomer.
- Tooth colored restorating material light cure composites comes in different forms(liquid and semisolid)
- And different shades that exactly matches to your tooth color.

Procedure
Depending upon the area of involvement the shape of the cavity is prepared, In case of decay, the involved surface should be thoroughly removed and cleaned.
The microscope is very helpful in seeing the field in higher magnification and operating with accuracy.
Irrigating the cavity with ozone water and gas kills the remnant bacteria and helps in preventing secondary caries.
These advanced methods contribute to a higher success rate.
