Replacement of  defective restorations is the commonest procedure carried out in general dental practice.  Replacement generally means some further loss of tooth substance and enlargement of the restoration.  Alternatives to full replacement have improved restorations and increased longevity. The aim of this study was to estimate the median survival time (MST) of marginal sealing, repair [read the full story…]
