- چکیده انگلیسی: Background: The efficacy of electronic continuing education courses in comparison to lectured based methods requires further evaluation. This study aimed at comparing the effect of electronic (e-learning) and face-to-face conventional instruction on level of knowledge of general dentists on bleaching of discolored teeth. Methods: In this quasi-experimental controlled trial study in 2017 (1396) with post-test and control group design, firstly, a lecture-based continuing education courses at Shahid Beheshti University on discoloration of a single tooth was carried out for general dentists (as the control group, N = 35). Then, a continuing education online course with the same topic was done for the second group (N = 35). Convenience sampling was used to select participants of each group. Data were collected by a researcher-made questionnaire, which consisted of 2 parts (post-test with 10 questions and a satisfaction questionnaire with 10 questions). Content validity and test-retest reliability (r = 0.8) of both was determined. Data analysis was performed using the t-test and Pearson’s chi square test using the SPSS 23 software. The level of statistical significant was considered at P = 0.05. Results: The mean knowledge score after education was 7.02 (2.87) in e-learning and 6.77 (1.23) in the conventional group. The difference between the 2 groups was not significant (P = 0.63). Overall, 91.4% in the e-learning and 91.5% in the conventional group believed that the educational course obviated their occupational needs. Conclusions: E-learning was as effective as conventional instruction for bleaching of a single discolored tooth in terms of knowledge score (post-test score) and self-reported satisfaction and attitude of dentists.

- چکیده انگلیسی: Statement of the Problem: Considering the high diagnostic accuracy and wide dynamic range of photostimulable phosphor plates (PSPs), they can be a good alternative for radiographic films.Purpose: This study was aimed to assess the effects of delay in scanning PSPs on the diagnostic accuracy of detection of approximal caries.Materials and Method: Radiographs from fifty-two extracted molar and premolar teeth were radiographed using DIGORA PSP (Soredex Corporation, Helsinki, Finland). The teeth were either intact or with non-cavitated approximal caries. The plates were scanned immediately (time zero) and at 10 min, 30 min, 60 min and 120 min after exposure. Sixty-five images were obtained and evaluated for presence or absence of approximal caries by two oral and maxillofacial radiologists and 2 restorative specialists. The diagnostic accuracy of approximal caries detection was measured using a 5-point rating scale. Definite presence of caries was confirmed using a stereomicroscope. Analysis of caries detection data was performed by calculating sensitivity and specificity using repeated measures with ANOVA.Results: Significant differences were found in complete negative predictive value, absolute negative predictive value and complete dentine sensitivity value between different scan times (p< 0.05). These values were significantly different at 10 min, 60 min and 120 min (p< 0.05). However, immediate scan and 30 min delay were not significantly different (p> 0.05). The accuracy of approximal caries detection at 120 min was less than at 60 min and at 60 min was less than at 30 min.Conclusion: In order to detect approximal caries more accurately, DIGORA PSPs should be scanned within 30 min after exposure.
