Abstract
We investigated the actual conditions of restorative treatment for young permanent teeth in the Pediatric Dental Clinic of the Tokyo Dental College from April 1993 to March 1994. The materials investigated in this study were 1700 permanent teeth from 758 patients aged from 5 to 19 years.
The most frequently treated restorations were composite resin restoration for the anterior teeth and metal inlay restoration for the posterior teeth. One tooth surface a tooth was the most frequently restored for both anterior and posterior teeth. Metal inlay restoration was performed frequently to two tooth surfaces a tooth, and composite resin restoration was performed frequently to one tooth surface a tooth for both anterior and posterior teeth. Almost of all of the teeth restored with glass-ionomer cement or silver amalgam involved one tooth surface a tooth.
The OL-cavity form in maxillary first molar, OB-cavity form in mandibular first molar were the most frequently prepared with metal inlay restoration. The cavity form included the M in the anterior teeth and the M or B-cavity form in the posterior teeth were prepared frequently for composite resin restoration. Cavity forms of each restoration took into consideration the characteristics of each restorative material. It seems that the glass-ionomer cement and silver amalgam were used for temporally restorations, so that, these two restorations were performed on the younger patients more frequently than on the patients receiving metal inlay restoration and composite resin restoration.
