National survey of endodontics in general dental practice in France.

The purpose of this paper was to gather both qualitative and quantitative information on endodontic treatments performed by French dental practitioners, and to identify the factors influencing the duration of endodontic procedures. A questionnaire was addressed in a two-rounds distribution to 2000 dentists selected by the quotas method in the whole country. A total of 790 (39.5%) questionnaires containing useful information were returned. The duration of endodontic treatment increases according to the number of roots to treat. The pulpal preoperative status has an influence on the duration of treatment, which is longer for a tooth with a necrotic pulp. Three variables strongly influence the duration of endodontic treatment: the number of patients attended per day, the number of appointments required for this treatment and the presence of a wage earner in the office. Continuing education also seems to be a variable having some influence on the duration of treatment. Financial considerations are also taken into account and there was general agreement that the current remuneration system of the French Health National Insurance is inadequate. Further, when one compares the total cost of an endodontic treatment with the fees fixed by the Health Insurance, it is clear that such procedures afford no positive financial return for a majority of practitioners. Moreover, the return becomes even more negative for teeth with a necrotic pulp. The findings presented in this study constitute the first stage of the medico-economic analysis concerning the endodontic practices in France. Prospective studies to gather precise information on the duration of endodontic treatments and a cost-analysis of endodontic practices could assist in the decision making process for practitioners or for the policy makers in the formulation of policies regarding application and reimbursement of endodontic treatment.
