Child discomfort and parental acceptability of silver diamine fluoride and alternative restorative treatment: A randomized controlled clinical trial.

Objectives: To compare pain perception of young children treated with SDF and ART, as well as their parents' acceptability of both modalities.

Methods: Eighty, 3 to 8-years old children, having at least one deciduous asymptomatic tooth with active caries, as defined by the ICDAS II scores 4, 5, 6 were randomly assigned into two groups; SDF for caries arresting in the test group, and ART for caries removal in the control group. Pain perception was assessed using Sound, Eye, Motor scale (SEM), whereas parental acceptability was assessed using a self-administered questionnaire.
