Dental Sealant,
Preventive Resin Restoration, &
Class I Composite Restoration
The unique advantages of the bonding technique allow for conservative restorative options such as dental sealant, preventive resin and class I composite restorations for incipient and small carious lesions in pits and fissures of posterior teeth. 
Dental sealant is a preventive measure that is used to prevent or delay the onset of dental caries, most often, in younger patients.
The entire occlusal surface is pumiced and rinsed.  Deep pits and fissures are examined and explored for potential caries and defects that are eliminated by a 1/4 round bur. If a moderate amount of caries is identified, then a preventive resin restoration (PRR) might be indicated.  The tooth is then etched, washed, and dried.
Dental sealant is placed and traced into the pits and fissures with a sharp explorer tip.  Gross excess sealant is removed with a microbrush to prevent occlusal interferences. The sealant is cured for 20 seconds per manufacturer's instructions.
