Abstract:
AIM:To analyse responses from dental practitioners (DPs) on how secure they felt as a newly graduated dentist, level of confidence or self-efficacy when performing root canal treatment (RCT), and if undergraduate (UG) education in Endodontics adequately met their needs in a dental practice. METHODOLOGY:An electronic questionnaire was sent to 459 dentists who graduated from the University of Bergen, Bergen, Norway, between 2008 and 2018. The survey consisted of questions with closed-end options and Likert scale (1-5). An open-ended free text option was always provided. RESULTS:A total of 314 (68.4%) DPs answered the questionnaire. Of these, 87 (27.8%) were men and 224 (71.3%) were women. Three respondents did not disclose their gender. As a newly graduated dentist, 37.3% of the respondents felt secure when performing RCT, 30.7% felt indifferent, and 32.0% felt insecure. The majority (72.4%) of respondents were either confident or very confident when performing RCT, 21.3% were indifferent, and 6.3% had little or no confidence. A majority of DPs (84.4%) self-evaluated the quality of their root fillings as good or very good, and 15.2% were indifferent. Only one DP selected 'not good' and none selected 'bad'. There were significant gender differences where male DPs felt more secure than female DPs when performing RCT (P < 0.001). A significantly larger number of men were very confident compared to women (P < 0.001). A logistic regression analysis using confidence as a dependent variable to predict self-efficacy revealed that DPs who felt secure when performing RCT as a newly graduated dentist had about 8 times more self-efficacy (odds ratio = 8.49) than those who were insecure or indifferent. Respondents who rated their quality of root fillings as good or very good had forty times more self-efficacy (odds ratio = 40.06) when performing RCT. UG education in endodontics was considered inadequate by 71.3% of the respondents where a significantly larger number of DPs (70%) wanted more clinical training (P < 0.05). About half the DPs (47.7%) stated that there was a need for lifelong learning with majority preferring hands-on courses and continuing dental education organized by dental associations. CONCLUSIONS:The results of this study suggest that there is a need to promote self-efficacy during UG education in Endodontics. Hands-on training is the preferred form of lifelong learning for DPs.
