Objective: This study was designed to evaluate the effect of using mineralized dentin particulate grafted for socket preservation. Patients and methods: The study was conducted on 20 patients seeking extraction of at least one hopeless tooth, they were randomly distributed into two groups, 10 patients in graft (test) group, and 10 patients for control group. In graft group, mineralized dentin graft was used as socket preservation, in control group, the socket was left to heal spontaneously by clot formation. Panoramic x-ray was taken for all patients before extraction, CBCT images were taken for all patients in two intervals, a- immediate post-operative, b- 6 months post-operative. CBCT images were used to compare horizontal and vertical ridge dimensions, and bone density values immediately post-operative and after 6 months of extraction.  Results: There was statistically significant decrease in horizontal and vertical ridge dimensions in both groups after 6 months, but the decrease of vertical and horizontal ridge dimensions in control group was statistically significantly higher than that in graft group, also bone density of graft group was statistically significantly higher than that of the control group after 6 months. Conclusion: Mineralized dentin particulate can be used as a good autogenous graft material for socket preservation giving promising results in reducing vertical and horizontal bone loss, and favorable bone density values after 6 months.
