[Sociodemographic and economic evaluation of periodontal care providers under a preliminary plan].

A prospective epidemiologic survey performed over a three months period was done in association with the Health Insurance Fund of Lyon, France. The major objectives of this study were to evaluate the credentials of practitioners prescribing periodontal therapy under the health plan. 72.9% of the dentists received their dental diploma within the last 5 years and were predominantly male. None of the practitioners were specialists. Apparently, periodontal therapy represented only 10% of the treatment prescribed by the dentists surveyed.
