Dissertation note: Thesis (M.Sc.) -. Future University in Egypt, Faculty of Oral and Dental Medicine, 2021. Summary: Dental caries can be better controlled by moving away from the traditional surgical approach to a new approach based on simple intervention in preventing caries, preventing their penetration into the dentin layer and restoring the missing part of the teeth with one of the adhesive fillings. SDF is the latest fluoride-containing product that has been proven in clinical studies to be effective in preventing the occurrence and spread of caries and is an ideal alternative treatment for tooth decay for many reasons. SDF treatment is painless, does not require local anesthesia, is accepted by children and can be used without drilling teeth. The purpose of this study was to investigate the effect of silver diamine fluoride on the microtensile bond strength of composite to dentin on primary and permanent teeth. This study included two groups: group 1 included twenty-four primary molars and group 2 included twenty-four premolars. Each group was further subdivided equally into sub-group A and sub-group B. Sub-groups A of each group were treated with a self-etch bonding system and 4-mm thick buildups of composite were placed with increments limited to 1 mm. Sub-groups B of each group were treated with 38% SDF then treated with the same self-etch bonding system used in sub-group A and composite were placed. After storage in distilled water for 24 hours at 37℃, the restored specimens were sectioned occlusogingivally into serial slabs approximately 1.0 mm thick by a slow-speed water-cooled diamond saw. Each slab was sectioned into composite/tooth structure beams measuring approximately 1.0*1.0 mm in cross-section, the beams were affixed to the test block of a micro-tensile testing machine to record maximum tensile force before failure occurred. One slab from each sub-group was evaluated under a scanning electron microscope and microphotographs were obtained.
