Potential use of silver Diammine fluoride in detection of carious dentin

This study aimed to examine whether discoloration of carious dentin after silver-diammine-fluoride SDF application might be used as a mean to detect demineralized-dentin. Fourty specimens were obtained from 20 human permanent teeth. Teeth were sectioned through the center of carious lesions to create 2-halves in which each half was assigned to a treatment group. Specimens were divided into two groups n=20 each half was assigned to one group according to solution, namely Caries Check CC, or SDF. SDF group was subdivided into 2 groups: Light-cured and 2-day storage groups. The specimens were tested using light-microscope, microhardness test and SEM/EDS analysis. Repeated-measures ANOVA was used for statistical analysis. The light-microscope showed superficial discoloration in the CC-group while SDF 2-day storage group showed deeper discoloration for the lesion area. SDF showed significant increase in the hardness compared with the CC-group. SDF showed potentiality to be used as an assisting-tool for caries detection.
