Background and Aim: Dentin sensitivity can be reduced through the formation of intratubular crystals from minerals from saliva or dentinal fluid, peritubular dentin formation, reparative dentin formation, and invasion of the tubules by bacteria or plasma proteins. Silver diamine fluoride application is new alternative treatments for dentin hypersensitivity. Present study was done with an aimed to evaluate the influence of the time of application of diamine silver fluoride on the hydraulic conductance of dentinal tubules. Material and Methods: The present study was conducted with a single-blind and randomized controlled design. The sample of this prospective experimental study included 90 healthy human third molars with indications of extraction in malocclusion. Groups of 15 dentin disks were obtained and divided in the following way. GC (no treatment), G1 (were actively treated with diamine silver fluoride for 15 s, e- sdf, Kids -e- dental LLP, India), G2 (30 s), G3 (60 s). Then, was measured hydraulic conductance of dentin. The rate of flow of the fluid through the dentin disks was measured by recording the initial position of a bubble of air inside a capillary in 20 min. Results: There is a statistically significant difference in hydraulic conductance between the control group and the samples treated with desensitizing solution based on diamine silver fluoride. There was no statistically significant difference between the groups treated with different application times of the desensitizing solution. Conclusion: Dentin hypersensitivity can effectively be reduced by utilization of silver diamine fluoride as a desensitization agent. Silver diamine fluoride has potential as a management for dentin hypersensitivity after instant application.
