Objectives The objective was to evaluate the current knowledge, attitude, and perception of adult patients toward SDF and identify related factors. Materials and methods In this cross-sectional study, data were obtained from adult participants of the Kingdom of Saudi Arabia. A simple random sampling method was used. An electronic questionnaire was designed to collect data regarding participants’ demographics and their knowledge, attitude, and perception toward the use of SDF. Results The majority (86.6%) of the participants were females. Approximately 58% were ≤ 25 years of age. Overall, 77.1% of the participants had college/higher level education, and 34.2% had a monthly income of > 16000 Saudi Riyals (SAR). Approximately 75.8% of them did not suffer from medical conditions, 60.8% had tooth decay, 82.5% brushed their teeth daily, 77.7% flossed regularly, and 63% used fluoridated toothpaste. Dental pain or inflammation was reported by 87.7% of the participants ( P -value < 0.001). A higher proportion of adult patients (47.8%) was strongly satisfied with the speed of treatment, 58.9% were strongly satisfied with advantages, and 24.5% were dissatisfied with disadvantages ( P -value < 0.001). Disagreement (24.0%) toward SDF material use for anterior teeth was statistically high ( P -value < 0.001). Females (64.5%) demonstrated strong satisfaction with the benefits of SDF material ( P -value = 0.004). Participants of male sex (26.0%), education up to high school (33.0%), and income of > 16000 SAR (31.0%) showed statistically strong disagreement ( P -value < 0.05) with use of SDF for anterior teeth. Conclusion The present study demonstrates that SDF is acceptable among Saudi adults for the purpose of arresting dental caries. However, pigmentation of anterior teeth is a major concern, especially in male participants with high socioeconomic status.

Objectives The objective was to evaluate the current knowledge, attitudes, and perceptions of parents toward the use of SDF in children’s primary teeth and identify related factors. Materials and methods In this cross-sectional study, data were collected from participants in Saudi Arabia. A simple random sampling method was used. An electronic questionnaire was designed to collect data regarding participants’ demographics and their knowledge,attitude, and perception toward the use of SDF. Results A higher proportion of parents/relatives (87.3%) was strongly satisfied with the speed of treatment and its benefits. In terms of disadvantages, 23.8% and 30.4% of the parents/relatives were satisfied and dissatisfied, respectively. Regarding attitudes, the majority of participants (22.8%) responded as neutral to using SDF to treat their children’s anterior primary teeth, whereas 32.2% agreed to the use of SDF in their children’s posterior primary teeth. A higher proportion of parents/relatives who were in the age group of > 50 years (27.8%) had responded as “satisfied” compared with the responses of other age groups. Conclusion The present study demonstrates that SDF is acceptable among Saudi parents/relatives for the purpose of arresting dental caries. However, pigmentation of anterior teeth is a major concern.
