Abstract
Purpose
Questionnaire surveys have been undertaken worldwide to investigate practices and knowledge related to carious lesion management, particularly in adults. The primary objective of this cross-sectional survey was to investigate restorative thresholds (RTs) used for carious lesions in primary molars by dentists practising paediatric dentistry in France. Dentists were surveyed by a specifically developed questionnaire based on clinical and radiographic caries classifications. The secondary objective was to explore restorative management strategies in primary molars.
Methods
A structured questionnaire assessing RTs and management strategies for occlusal and approximal carious lesions of primary molars was anonymously and electronically administered via SurveyMonkey® to dentists who were members of the Société Française d’Odontologie Pédiatrique. Descriptive analyses, Chi-square test, McNemar test, and logistic regression analyses considering dependent RT variables for occlusal and approximal carious lesions were performed.
Results
Among 250 dentists surveyed, 201 responded (response rate 80.4%). Overall, 43% (n = 87) and 75% (n = 151) of respondents would place their RTs in enamel for occlusal and approximal lesions, respectively. Dentists with an exclusive practice of paediatric dentistry more frequently would choose a RT in dentine for approximal lesions than did other dentists (p = 0.010). A preparation technique including sound dental tissues was less frequent for occlusal than approximal lesions (n = 31; 15% vs n = 60; 30%). Overall, 75% (n = 151) of respondents used the same restorative material for occlusal and approximal lesions.
Conclusion
In general, dentists practising paediatric dentistry in France overtreated lesions on primary molars, which contradicts minimal intervention recommendations. RTs are too often indicated for enamel-confined carious lesions.
