ULTRACONSERVATIVE AND CARIOSTATIC SEALED RESTORATIONS - RESULTS AT YEAR 10

Changes in restorative techniques and the development of newer restora tive materials have allowed for the use of more conservative cavity pr eparations. This 10-year study evaluated bonded and sealed composite r estorations placed directly over frank cavitated lesions extending int o dentin vs. sealed conservative amalgam restorations and conventional unsealed amalgam restorations. The results indicate that both types o f sealed restorations exhibited superior clinical performance and long evity compared with unsealed amalgam restorations. Also, the bonded an d sealed composite restorations placed over the frank cavitated lesion s arrested the clinical progress of these lesions for 10 years.
