Background: Dentin hypersensitivity (DH) is a common clinical condition caused by exposed dentinal tubules. Silver diamine fluoride (SDF)-based desensitizers are widely used due to their tubule-occluding ability. This study aimed to compare the efficacy and durability of SDI Rivastar (SDI Ltd., Bayswater, VIC, AUS) and CariCure SDF (Prevest Denpro Limited) in dentinal tubule occlusion. Materials and Methods: Fifty dentin specimens were prepared from twenty-five extracted premolars and treated with 17% EDTA. Samples were divided into control, Rivastar and CariCure SDF groups. SEM analysis was performed immediately and after 30 days of simulated brushing. Data were analyzed using Kruskal–Wallis and Mann–Whitney U tests. Results: Both agents significantly occluded dentinal tubules compared to control (p<0.001). CariCure SDF showed superior immediate occlusion. After 30 days, both agents maintained significant tubule occlusion with no statistically significant difference. Conclusion: CariCure SDF (Prevest Denpro Limited) demonstrated better immediate occlusion, while both agents showed comparable long-term effectiveness.
