The article discusses a clinical technique which was successful in eliminating postoperative sensitivity after placement of posterior composite dental resin restorations. The technique involved protection of the dentin before acid etching and appropriate placement of the composite resin material. For the technique, freshly extracted premolars were placed in formalin and refrigerated for scanning electron microscopy. It was observed that dentin adhesive materials were not effective in sealing the dentin tubules if the acid contacted the adhesive, also, that postoperative sensitivity can be eliminated by employing this technique which protects the dentin, bevels the enamel, and places the resin material in thin increments along the cavity walls until restoration is completely built up.
