Are Brazilian dentists and dental students using the ICCC recommendations for caries management?

The aim of this study was to evaluate whether dentists and dental undergraduate students know the terminology of the International Caries Consensus Collaboration (ICCC), and make their restorative treatment decisions regarding carious tissue removal accordingly. Data collection was performed using an electronic questionnaire, considering: a) profile of the respondent; b) analysis of four clinical cases with respect to possible management strategies; and c) questions on cariology field terminology. Sample size consisted of 175 dentists and 66 last semester dental students. Statistical analyses were performed comparing profile, type of institution and dental specialty of the participants. Results showed students were less conservative and agreed less with the ICCC than dentists, and private schools, less than public institutions. Private institutions were 12% (95%CI = 0.833-0.949; p = 0.000) more likely to be less updated with the ICCC recommendations than public institutions, and dentists were 20% more likely to agree with them than students (95%CI = 1.118-1.302; p = 0.000). Dentists were 66% more likely to be conservative than students (95%CI = 0.203-0.554; p = 0.000); dentists and students who graduated or were graduating from public universities were twice as likely to be conservative as those from private universities (95%CI = 1.336-3.333; p = 0.001). In conclusion, students in the last semester are less conservative than dentists, and respondents who graduated or were graduating from public dental schools were more aligned with the current concepts of the ICCC. Several answers were not aligned with ICCC directives, thus showing that management of deep carious lesions still causes restorative therapeutic insecurity.
