Removing sound tooth (enameloplasty) and replacing it with Resin or Sealant material is called
PRR- Preventive Resin Restoration.
Sealants that are most likely to require occlusal adjustment
Filled sealants
Type of sealant that can be placed in wet environment with no etching necessary and are able to release high fluoride
Glass ionomer
Major reason for Sealant fail is
Saliva contamination

37-50 %
Reduction of pits and fissure caries by obliterating the pits and fissures with a high speed drill and filling them with amalgam is called
Prophylactic odontonomy
