Management of pulps exposed during carious tissue removal in adults: a multi-national questionnaire-based survey.

OBJECTIVES: The aim of the present study was to investigate and compare the management of pulps exposed during carious tissue removal by French, German, and Norwegian general dental practitioners (GDPs). We further aimed to assess possible dentist- and patient-related factors associated with these management decisions. MATERIALS AND METHODS: A structured questionnaire was send via mail to a simple random sample of dentists. RESULTS: The analyzed sample consisted of 661 (33%) French GDPs, 622 (25%) German GDPs, and 199 (34%) Norwegian GDPs. No single management method gained uniform consensus in any of the three countries. However, the most preferred management option in all three countries was direct pulp capping (DPC) (68-93%) mainly performed with calcium hydroxide paste/slurry (CH). Alternatively, root canal treatment was performed (7-22%). The reasons that guided GDPs were the same in all three countries; "good results" and "ease of use, familiar with the technique." Having read scientific articles about cariology/operative dentistry in the last 5 years increased the odds for the preference of DPC instead of root canal treatment (OR = 2.1, 95% CI 1.3-3.2). CONCLUSIONS: Among GDPs in France, Germany, and Norway, there was no uniform management option for pulp exposures during carious tissue removal. DPC with CH was the most preferred management, even though the current evidence suggests DPC with mineral trioxide aggregate (MTA) to be more successful. The outcome expectations and the assumed ease of use were reasons for GDPs' choice. Moreover, knowledge on current evidence towards such management options influenced treatment decisions. CLINICAL RELEVANCE: GDPs are encouraged to adopt management options based on current scientific evidence.

Dentists' attitudes and behaviour regarding deep carious lesion management: a multi-national survey.

OBJECTIVES: The present study aimed, using a questionnaire, to assess and compare behaviour, attitudes and beliefs of French, German and Norwegian dentists regarding deep carious lesion management. MATERIALS AND METHODS: A mail survey was applied to simple random national samples of dentists. Descriptive analysis and logistic regression analysis were performed. RESULTS: Sample size was 661 (response rate, 33 %) in France, 622 (25 %) in Germany and 199 (33 %) in Norway. Hardness was the criterion used most often for assessing carious tissue removal in all three countries (>95 %), with most dentists aiming for only hard dentine remaining at the pulpal wall (>66 %); dentine colour was not found relevant by most respondents. The majority of French and German practitioners (>66 %) would perform complete excavation even for deep lesions, while most Norwegian dentists (84 %) opted for stepwise excavation. Most dentists thought complete removal was required to avoid lesion progression and were uncertain if remaining sealed bacteria would harm the pulp. Treatment decisions were guided by prior experience and familiarity. For example, stepwise removal was performed less often by dentists who were male, French, German or those in the private sector. CONCLUSIONS: Less invasive strategies for managing deep lesions have not widely entered clinical practice in France and Germany. Underlying beliefs shape decision-making. CLINICAL RELEVANCE: The present study is the first of its nature to analyse and compare deep carious lesion management between three European countries. It shows that there is an urgent need to practically educate dentists in less invasive strategies.
