[A statistical survey of the fabrication of single restorations (in 2002)].
A statistical survey based on laboratory records was carried out to determine the state of fabrication of restorations at the dental hospital of Tokyo Medical and Dental University during the six month period from April 1 to September 30, 2002. A comparison was also done with a previous survey that had been carried out in 1986 and 1997 to detect the possible change and alternations in the near future. From the findings of this survey, the following conclusions can be drawn. 1. A total of 7,864 restorations were fabricated during the six months in 2002, and of these, 6,740 restorations (85.7%) were covered by health insurance, and 1,124 (14.3%) were not. 2. Compared with the previous data in 1986 and 1997, decreased numbers of inlays and cast post & cores were the distinctive features that affected the decrease of total numbers. 3. The rate of restorations that were not covered by health insurance slightly increased to 14.3%, compared with 12.3% in 1997.
