Disparities among dental schools concerning the teaching and practice of cariology and operative dentistry can lead to variations in students' treatment modalities that can have health and economic consequences for patients and third party providers. The purpose of this study was to assess caries management strategies taught in French dental schools employing a questionnaire used in a previous study involving private dentists. The study population consisted of 180 teachers of operative dentistry. Each teacher received a questionnaire and a reply-paid envelope. The questionnaire assessed their treatment strategies, knowledge and beliefs about selected aspects of diagnosis, and treatment of dental caries. After one reminder, the response rate was 49.1 percent. The results illustrate a wide disparity among French teachers concerning restorative treatment thresholds for approximal surfaces, opinions about the rate of caries progression, and the need to monitor lesions near the DEJ. The teachers' attitudes differed from those of private practitioners: they tended to intervene surgically at a later stage, but they would intervene earlier in the treatment of the carious process than would Scandinavian dentists. This study may help in encouraging dental faculties to develop a consensus on issues related to diagnosis and management of dental caries.
