Reasons for restoration replacement: differences in practice patterns.

Abstract

Patients receive varying types and amounts of restorative treatment, depending on the prescribing dentist. The aim of this study was to enhance the understanding of the variation of the restoration replacement practices of dentists. Three dentists in private practice in similar semirural communities with comparable practice demographics were asked to gather data on all restorations they replaced over a period of 1 month. They recorded the tooth number, number of restored surfaces, restorative material being replaced, number of surfaces in the replacement restoration, the replacement restorative material, and the reasons for the replacement restoration. Statistically significant differences were found among the dentists as to the reasons for posterior restoration replacement, replacement materials used, and increase in size of the replacement restorations. Differences were attributed to individual practice philosophies, demonstrating that clinical information was not the sole determining factor as to type of replacement restorations that patients received.
