    Analyzing Content and Quality of YouTube™ Videos on Removal of Amalgam Fillings
    (Marmara Üniversitesi, 2022) Buldur, Mehmet; Bal, Fatma Aytaç
    Objective. The objective of this study was to analyze the information quality and content of operational videos available on YouTube™ regarding amalgam fillings removal. Methods. Videos were determined using the words “Removal of amalgam fillings” and “Replacement of amalgam fillings” in the YouTube™ search section. 85 videos were included for analysis. Demographics of videos, viewers’ interactions, and viewing rates were evaluated. The videos were analyzed in two parameters in terms of Audio-visual quality and the SMART (Safe Mercury Amalgam Removal Technique) protocol steps. Results. It was determined that dentists accounts ranked first (62%) in the distribution of video sources. While only 19% of the videos were of “Excellent” audio-visual quality, 49% were rated as “Moderate” and 33% were rated as “Poor”. In the SMART evaluation, while only 10% of the videos got the “Maximal Useful” score, the majority of the videos got the “Slightly Useful” score (58%). There was no statistical relationship between the “View Rate” and “Interaction Index” variables of the videos (p> 0.05). Conclusions. Operational videos about the removal of dental amalgam fillings should be uploaded to YouTube™ after approval by the experts of the subject. Students should be warned about videos which contain insufficient information. Videos should be prepared in line with current information in the literature.

    Twenty-Four-Month Clinical Comparison of Two Bulk-Fill and a Microhybrid Composite Restorations in Class II Cavities
    (Dennis Barber Ltd, 2021) Karaarslan, Emine Sirin; Bal, Fatma Aytac; Buldur, Mehmet; Altan, Halenur
    Objectives: The aim of this study was to evaluate the clinical performance of two bulk-fill composite resins in Class II cavities for up to twenty-four months. Materials and Methods: total 75 Class II restorations were made in 25 patients using two nanohybrid bulk-fill resin composites and a micro hybrid composite. The restorations were evaluated at baseline and at 6, 12, and 24 months, using U.S. Public Health Service (USPHS) criteria. The restoration groups were compared using the Pearson chi-square test, and the Cochran Q-test was used to compare the changes across different time points within restorative materials (p<0.05). Results: Two patients who did not attend the appointments were excluded from the study, so 23 patients were evaluated with a 92% recall rate; at the end of the two-year follow-up, 66 restorations were evaluated. Three restorations underwent endodonlic treatment and were deemed failures. The overall success rate was 96%. There were statistically significant differences between the three restorative resins in terms of color match parameter (p<0.05). No differences were observed between the restorative resins in terms of other criteria (p>0.05). Conclusions: During the two-year follow-up period, the three composite resins showed similar clinical performance except for the color match parameter.
