Introduction: Prevention and control of dental caries is a challenging task in children. Silver diamine fluoride (SDF) has shown promise in arresting caries and preserving healthy tooth structure. However, data on dental students’ knowledge and use of SDF are limited, and improving their understanding could enhance management of deep lesions in uncooperative children and those with special health care needs. The aim of this study was to assess the knowledge, attitude, and barriers to the use of silver diamine fluoride among undergraduate dental students.

Material and methods: The study was conducted among dental students (IV BDS and Interns) in Goa Dental College and Hospital. A customized, self-administered, printed questionnaire assessing the knowledge, attitude, and barriers to the use of silver diamine fluoride was designed, validated by ten subject experts and pilot tested prior to the commencement of the study. The questionnaire was provided to each student willing to participate in the study. Data obtained was tabulated and statistically analysed.

Results: A total of 149 students were included in the study. 61.4% had heard about SDF from dental schools. Most students had basic knowledge about SDF. 65.7% of the students were not using SDF, the most common reason being a lack of adequate knowledge/ expertise with the material. 74.2% students would you consider using SDF in the future.
