This is a report on the statistical classification of the prosthetic restorations placed in out-patients of the Tokyo Medical and Dental University Hospital. The data were collected from the laboratory records during the period of January to June of 1986. The results are summarized as follows: 1. The total number of the prosthetic restorations placed in the outpatients were 7355, and 56% of these were covered by the health insurance. 2. Of the total restorations, 29.6% were cast cores, 18.2% were inlays and 17.2% were crowns. Post crowns, jacket crowns and partial veneer crowns were very few, being only 0.3%, 0.4% and 0.5%, respectively. 3. Approximately 50% of the prosthetic restorations were single crowns. 4. Compared to the record from about 20 years ago, the number as well as the ratio of the crowns including the facing crowns was approximately doubled. On the contrary, the number of jacket and post crowns has remarkably decreased. 5. With regard to the single anterior prosthetic restorations, the majority were the porcelain fused to metal crowns which were not popular 20 years ago.
