Introduction:The novel coronavirus disease has become an important public health problem that may have negative effects on psychological health. Objectives: This study aims to evaluate the views and anxiety levels of dental students during COVID-19. Material and methods: A questionnaire consisting of COVID-19 and online education views was filled by the students of a dental faculty. For the determination of the anxiety levels, the participants completed Turkish versions of the state-trait anxiety inventory (STAI) scales. The data was analyzed using descriptive analysis and parametric statistical tests. P < 0.05 was accepted as significant. Results: A total of 249 dental students (154 females, 95 males), including 143 preclinical and 106 clinical students participated in the survey. Most students (81.1%) stated that they were concerned that the classes would be held in groups, with the transition to face-to-face education. Most of the participants (69.9%) stated that the idea of late graduation creates fear. Due to the COVID-19 pandemic, approximately a quarter of the students have the idea of changing professions. The continuity anxiety value of the group with the idea of changing the profession was statistically higher than the other groups (p < 0.05). Conclusions:The results of our study indicated that dental students in our study were anxious about COVID-19. Our results emphasize the need to create psychological support programs for dental students during and after the pandemic.

This study aimed to analyze the videos available on YouTube related to dentistry and the novel coronavirus (COVID-19), as there is no such analysis in the existing literature. The terms “dental” and “COVID-19” were searched on YouTube on May 9, 2020. The top 116 English-language videos with at least 300 views were analyzed by two observers. Data was saved for each video, including target audience, source, country of origin, content, number of views, time watched, average views, duration, like/dislike ratio, and usefulness. Total video information and quality index (VIQI) scores were calculated, consisting of flow, information, accuracy, quality, and precision indices. Non-parametric tests were used for analysis. The analyzed videos were viewed 375,000 times and totaled 20 h of content. Most videos were uploaded by dentists (45.7%), originated from the United States (79.3%), and contained information targeted towards patients (48.3%). Nearly half of the videos (47.4%) were moderately useful. For the usefulness of the videos, statistically significant differences were found for all indices as well as total VIQI scores. A comparison of the indices according to the relevance of the videos showed statistically significant differences in the videos’ information and precision indices and total VIQI scores. The results of this study showed that dentistry YouTube videos related to COVID-19 had high view numbers; however, the videos were generally moderate in quality and usefulness.

Significance of the Study• The aim of this study was to compare cone-beam computed tomography (CBCT) and panoramic radiography (PR) for the detection of tonsilloliths. • The detection rate of tonsilloliths was 33.2% on CBCT. • Only 51.4% of the tonsilloliths detected on CBCT were identified by PR. • PR was not adequate to detect tonsilloliths 1 mm or smaller in size. AbstractObjective: A tonsillolith is a concretion of the tonsillar crypt. The aim of this retrospective study was to compare panoramic radiography (PR) and cone-beam computed tomography (CBCT) for the detection of tonsilloliths. Materials and Methods: The CBCT images of 527 patients with maxillofacial volume were evaluated retrospectively. Of these, 175 patients (81 females, 94 males; mean age 51.05 years) had unilateral or bilateral tonsilloliths. In total, 151 of them (67 females, 84 males; mean age, 51.03 years) had PR images performed in the same period and were included in the study. The PR images were examined to ascertain whether known tonsilloliths (from CBCT images) could be detected. The location (unilateral; left or right and bilateral), size, and number of the tonsilloliths were examined on both CBCT and PR images. Descriptive analysis, Spearman's rho correlation coefficient, and χ 2 tests were used for the statistical analysis. Results: The detection rate of tonsillolith was 33.2% on CBCT images. Only 51.4% of the tonsilloliths detected on CBCT were evaluated by PR; the correlation between CBCT and PR was found to be significant (Spearman's r = 0.399, p = 0.000). PR was not adequate to detect tonsilloliths 1 mm or smaller in size. All the calcifications larger than 5 mm were detected on PR images. Conclusion: The results of this study showed that more than half of the tonsilloliths observed in CBCT were also detected in PR. Tonsilloliths larger than 2 mm were more likely to be detected on PR images.
