Background: The use of antibiotics prophylactically and therapeutically in dentistry has become common practice. Inappropriate prescription may lead to adverse side effects and bacterial resistance. During clinical training, dental students in Saudi Arabia are authorized to prescribe antibiotics. Aim: To evaluate dental students’ knowledge and attitudes regarding antibiotic prescription in Riyadh, Saudi Arabia. Methods: A cross-sectional study based on a validated questionnaire consisting of 34 questions focusing on antibiotic indications in dentistry, antibiotic regimens, and knowledge regarding resistance was distributed amongst dental students in five leading dental colleges in Riyadh. Results: A large proportion of students (71.7%) were familiar with the concept of antibiotic resistance. When comparing junior and senior dental students’ knowledge with regards to indications of antibiotic use in commonly encountered conditions, it was found that there was no significant difference in antibiotic prescription frequency between these groups. Most dental students choose to prescribe amoxicillin as their first-choice of antibiotic (88.4%), and most also chose to use it for a duration of 3–5 days (69.2%). Conclusions: This study concludes that dental students may prescribe antibiotics inappropriately to manage various conditions when not indicated. This may indicate a defect in education of students with regards to current antibiotic guidelines.

Tudy aims to determine the perceptions of clinical dental students toward smoking cessation counseling and the barriers to promote it. Settings and Design: This cross-sectional study was conducted in Riyadh, Saudi Arabia in July 2017 among clinical dental students and interns of five dental schools. Subjects and Methods: We used a questionnaire derived from a similar study. The online questionnaires were distributed through social media. Statistical Analysis Used: Data analysis was achieved using SPSS 24.0 Mac version (Release 24.0, IBM, USA) through Chi-square test. Statistical significance was considered at P < 0.05. Results: A total of 291 individuals participated in the study. Most of the respondents were nonsmokers (79.4%). In comparison between junior and senior dental students with regard to their perceptions of smoking cessation counseling, it was found that there was no significant difference between the two groups. Most of the respondents were interested in becoming trained on how to assist patients to quit (72.9%). Furthermore, the majority of participants inquired about their patients' smoking status (87.6%). The most frequently cited barrier was lack of training to help patients quit smoking (67%). Conclusions: This study identified the lack of appropriate training and insufficient knowledge toward tobacco use cessation counseling....
