Summary

The aim of this study is to determinate the influence of an alternative adhesive application protocol (i.e. consecutive application of an extra adhesive layer)on restoration longevity in primary molars.

Conditions

  • Dental Caries
  • Secondary Dental Caries

Interventions

PROCEDURE

Three adhesive coats

After caries removal, enamel margins will be conditioned with phosphoric acid gel 37% by 15 seconds and dentin walls by 8 seconds. The etchant will be removed with use of water spray by 30 seconds. The water excess will be removed with a cotton pellet. The first layer of Prime \& Bond 2.1 adhesive will be applied with a microbrush. After 20 seconds a second layer will be applied and after a similar period a third layer will be applied over cavity walls. Again, after 20 seconds, the layers will be gently air-dried and photopolymerized by 10 seconds with a LED photoactivation unit.

The water excess will be removed with a cotton pellet. The first layer of Prime \& Bond 2.1 adhesive will be applied with a microbrush. After 20 seconds a second layer will be applied and after 20 seconds, the layers will be gently air-dried by 5 seconds. The two layers will be photopolymerized by 10 seconds with a LED photoactivation unit.
