Preventive resin restorations and sealants in light of current evidence.

Pit and fissure sealant should be treatment option provided to all children, particularly at the age immediately after eruption of the posterior teeth and especially, but not exclusively, the permanent teeth. Preventive resin restoration is minimally invasive procedure that should be the treatment of choice for small carious lesions in the posterior teeth. The Class I amalgam should not be placed as a first-time restorative material to treat incipient or small carious lesions under any circumstances. The amount of tooth structure removal necessary for Class I Black preparation, which requires sufficient depth of amalgam and extension for prevention, is an unacceptable treatment when minimally-invasive options are available.
