Iatrogenesis in the treatment of dental caries.

Traditional restorative dental treatment has many shortcomings and has not been shown to be an effective method for managing caries. In spite of this, many dentists continue to be powered by an aggressive restorative approach which, in the light of changing "rules" of operative dentistry, must now be seen as inappropriate and as a form of iatrogenesis. Many things have changed in recent years, including: the prevalence of caries; understanding of the science of the caries process; a fuller appreciation of the problems inherent in restoring teeth; cavity design; restorative materials; and the demands of patients. Dental practice needs to change very dramatically if iatrogenesis is truly to be reduced to a minimum and dentistry is to provide the sort of preventive-based care the modern consumer is increasingly realising makes most sense.
