Dental Composite Restoration Treatment Levels and 5-Year Cumulative Exposure during the 5-Year Trial among 444 Children in this Analysisa
| Compomer | Composite | Total Composites | |
|---|---|---|---|
| Number of Teeth Ever Filled | 2.3 (2.7) | 1.7 (2.5) | 4.0 (4.1) |
| Number of Posterior Occlusal Surfaces Ever Filled | 2.0 (2.5) | 1.3 (2.1) | 3.3 (3.7) |
| Surface-Years of Exposure | 11.8 (17.9) | 10.3 (17.2) | 22.2 (25.3) |
| Posterior Occlusal Surface-Years of Exposure | 5.5 (8.2) | 4.6 (8.2) | 10.1 (12.1) |

Columns present mean (SD) for children who received any restoration treatment on posterior or anterior teeth with each specific material, and are not mutually exclusive. “Total composites” includes both compomer and composite restorations. Among children randomized to the composites treatment plan (n=224), compomer was used for primary dentition and composite for permanent dentition. Among children randomized to amalgam treatment (n=220), compomer or composite was used for anterior tooth surfaces per NECAT protocol and standard clinical practice. Materials applied were Dyract compomer and Z100 composite.
