This study assessed the knowledge on and attitude toward silver diamine fluoride among Saudi dental practitioners in Riyadh public hospitals. Materials and Methods: A cross-sectional study was done, data were collected between July and October 2019 using a validated, and the published questionnaire was analyzed. A sample size of 278 public hospital dental practitioners in Riyadh, Saudi Arabia, was used. Participants who agreed to the study completed a 3-section questionnaire of Likert scale comprising multiple questions regarding demographic data, knowledge on silver diamine fluoride, potential, and actual use of SDF in dental practitioner's own professional life. Finally, respondents were asked about the future usage of SDF. Results: A total of 278 Saudi dentists in Riyadh public hospitals completed the survey. The mean knowledge of SDF among participants was averagely 3.1. About half of the participants (50.4%) agreed that SDF could be used to arrest cavitated lesions. The majority of respondents showed a positive attitude toward SDF by accepting it as a good alternative treatment for individuals with behavioral problems or medical issues (>50%). The most frequently reported barrier to the use of SDF was black discoloration (55.39%). A high number of respondents have not experienced the application of SDF, in their practice (>60%), or dental school (65.5%). However, 57.9% expect an increase in the future use of SDF. The correlation between knowledge and attitude among different dental specialties was statistically significant (P<0.05). The restorative specialty was observed to have the highest mean of knowledge (3.26), while advanced education general dentistry had the highest mean (3.67) of attitude toward SDF. Conclusion: The aim of the study was achieved as the knowledge on, and attitude toward silver diamine fluoride among Saudi dental practitioners in Riyadh public hospitals was assessed. The response was average, with means of 3.1 and 3.3 for knowledge and attitude, respectively, among the participants.

The gold standard for restoring Endodontically Treated Teeth (ETT) with successful clinical longevity requires having minimal invasive preparations and maximal tissue conservation. Many dentists still consider hybrid post/core/crown to be the first choice for restoring ETT. Endocrown is a viable alternative treatment modality to hybrid post/core/crown. This study aims to assess the proper judgment of dentists working in Riyadh, Saudi Arabia on the use of monolithic endocrown versus hybrid post/core/crown for restoring ETT. The IRB of Princess Nourah Bint Abdulrahman University (PNU) Institutional Review Board reviewed this study. The questionnaire was validated and electronically distributed. The participants were pre-informed that their responses are completely anonymous and used for professional purposes only. The questionnaire surveyed dentists working in Riyadh, Saudi Arabia, about their preference for different ETT restorative modalities at various clinical scenarios. Data were analyzed using One-way ANOVA and t -test. All P-values of < 0.05 were considered statistically significant. A total of 275 responses were collected; 61.45% were females and 38.55% males. 56% of them were general practitioners, while 16% were consultants. Prefabricated post/core was the most preferred technique among the participants (18.55%), followed by endocrown (12.36%), and lastly, cast post/core (8.73%). The amount of remaining tooth structure was the most influential in the treatment selection (30.18%), followed by the presence or absence of 1–2 mm ferrule (17.82%). Interocclusal space (12.36%) was the least influential factor. Endocrown recorded 63.27% as the most preferred line of treatment in case of insufficient inter-occlusal space. 40.36% preferred endocrown for patients with occlusal risk factors. The amount of the remaining tooth structure and the tooth position significantly affect the treatment options of the participants. Endocrown was the most preferred treatment modality for restoring ETT for patients with occlusal consideration.
