Objectives: The objective of this study was to describe the knowledge, opinions and practices about the defective
restoration (DR) management of French general dental practitioners (GDPs).
Methods: A cross-sectional, online survey-based study was carried out amongst 378 GDPs – members of the dental
practice-based research network in France (ReCOL). Bivariate comparisons were made using Fisher’s exact test to
assess the association of the respondent characteristics (age, gender…) with the decision to repair DRs, and
responses to clinical cases.
Results: The response rate was 82.9%. 50.4% of the respondents declared they at least sometimes consider DRs
repair in their clinical practice instead of DRs total replacement. For the 89.8% who at least rarely repaired DRs,
the main characteristic determining the therapeutic strategy was the defect size (71%, mainly inclined to repair
small defects), followed by the defect type (marginal defect or crack for more than 60% of the respondents) and
the material of initial restoration (composite for 63.5%). When shown clinical photographs illustrating DRs, most
of respondents proposed a replacement with inlay/onlay or crown.
Conclusions: This study indicates that a significant proportion of French GDPs do not make sufficient use of DR
repair on a routine basis. A lack of knowledge of the concept seems to explain at least part of this situation.
Collective and individual efforts from the profession are still needed to promote DR repair and therefore more
often apply Minimal Intervention Dentistry.
Clinical significance: This survey shows that MID is not yet sufficiently used in routine practice in France regarding
DR management. Further efforts (continuing education toward MID, public funding revaluation for MID strategies…) are needed to help GDPs to implement MID into everyday practice.
