Background A major shift has occured in the trend of dealing with dental caries from primary to secondary prevention, specially after SDF approval off-label by US FDA in recent years and Hall Technique (HT) in the last decade. Objectives To determine the frequency of awareness and use of Silver Diammine Fluoride (SDF) and Hall technique among dental professionals in the Eastern province of Saudi Arabia. Methods This cross-sectional study was conducted in a public hospital, metropolitan city of Middle Eastern region between March 15, 2019 & January 31, 2020. Dental practitioners were requested, with their consent, to fill up a digitally designed survey. Chi-square test on SPSS-20.0 was applied to compare frequency of awareness and use of SDF and HALL Technique among the survey participants. Results The awareness of SDF was found to be 73.6% among specialists, 54.9% among graduates and 29.6% among students whereas awareness of HALL technique for stainless steel crown in pediatric dentistry was found statistically similar in all participants groups i.e. 42.7% in students, 55.5% in graduates and 54.9% in specialist group (p = 0.125). Conclusion The results show potential with regards to awareness of dental specialists & postgraduate residents but inadequate among general dentists and students though all were keen advocates and found committed to its use to help the community. It points towards a further need of the of education for all groups. Those non- invasive techniques are very useful tools in general but specifically during Covid-19 pandemic where they can play a major role in preventing the spread of infection, arresting decay, alleviating pain and anxiety without resorting to aggressive treatment like pulp treatment/extraction. Low response rate may be improved in future through the respondents’ counselling and regular follow up.
