Abstract
This report investigated 1,466 primary-tooth restorations in 374 children, who attended the Nagasaki University Dental Clinic of Pediatric Dentistry in 1994. Data resulting from the investigation were compared with those obtained in 1984.
Results and Conclusions
1. Of all the restorations performed in 1984,37.5% were composite resin fillings; 28.8% were stainlesssteel crowns; 16.6% were metal inlays; 11.3% were amalgam fillings. On the other hand, of all the restorations performed in 1994,60.3% were composite resin fillings; 21.0% were metal inlays; 14.1% were stainless-steel crowns.
2. In 1984, of primary molars with decayed proximal surfaces,75.4% were restored with metal inlays,14.3% were restored with composite resin fillings and 10.0% were restored with amalgam fillings. In 1994, of the decayed proximal surfaces of primary molars,51.0% were restored with metal inlays and 47.5% were restored with composite resin fillings.
3. Both in 1984 and in 1994, composite resin fillings were used preferentially for primary anterior teeth in which caries extended only into the enamel or only into the dentin, and for primary molars in which caries extended only into the enamel. In 1994, composite resin fillings were used preferentially for primary anterior teeth in which caries extended into the pulp and for primary molars in which caries extended only into the dentin, too.
4. Compared with the results in 1984, in 1994, the percentages of the composite resin fillings increased both for primary anterior teeth and for primary molars. In 1994, no amalgam filling was used and glass-ionomer cement fillings were used as a new method.
