A survey conducted in 2002 among French general dental practitioners (GPs) showed variations between treatment decisions and a tendency towards early restorative intervention for caries. The aims of the present questionnaire survey were to investigate, among a random sample of 2,000 French GPs, the management decisions for occlusal lesions in 2012 and to compare the results to those obtained in 2002. The response rate was 41.9%. The majority of the respondents (60.7%) would postpone their restorative decisions until the lesion was in the dentin, based on clinical and radiographic examinations. Almost 68% of the respondents suggested that the cavity preparation should be limited to the lesion (vs. a preparation extending to the occlusal fissure), and 81.6% chose composite as restorative material for the earliest lesion requiring restoration in a 20-year-old patient with his/her caries risk factors under control. Statistical analysis (χ2 and logistic regression) showed that the management decisions were influenced by certain demographic characteristics (gender, clinical experience and participation in cariology courses). When comparing the 2002 and 2012 responses, it appears that even if French GPs still tend to intervene surgically for occlusal lesions, which could benefit from noninvasive care such as therapeutic sealants, the restorative threshold has been delayed to later stages of carious progression (p < 0.0001). Moreover, the 2012 respondents were less likely to open the fissure system than the 2002 respondents (p = 0.032), and less amalgam restorations would have been placed in 2012 (p < 0.0001). Furthermore, the results showed that the variability observed in 2002 toward caries management decisions was persisting in 2012.
