Purpose: The aims of this study were 1) to evaluate clinically and radiographically differences in bone volume and density between particulate partial-demineralized dentin graft (PDDG), mineralized dentin graft (MDG) and freeze-dried bone allograft (FDBA), and 2) to evaluate differences in terms of efficacy among partial-demineralized dentin graft, mineralized dentin graft and FDBA. Material and methods: Adult patients seeking extraction treatment at the University of Oklahoma, College of Dentistry were recruited for this study. Patients were randomly assigned to three groups: Group I: mineralized dentin graft (MDG), Group II: partial-demineralized dentin graft (PDD), Group III: FDBA. Clinical and radiographic measurements were taken using a custom stent that had positions for a bone caliper to be inserted at the buccal and lingual surfaces at 2 mm and 4 mm apical to the alveolar ridge of the target tooth. Clinical measurements were taken during extraction and 6 months after extraction (during implant placement). Radiographic alveolar bone changes of buccolingual ridge width, ridge height, and density were assessed on CBCT scans obtained at 2 weeks and 4 months postoperatively. Results: A total of 118 sites on 35 patients were clinically and radiographically analyzed. When comparing the differences of means between pairs of graft materials regarding alveolar ridge width and height changes, the differences between FDBA-PDDG and FDBA-MDG were statistically significant (p0.05). Height bone change for the FDBA group was -0.64 mm; the MDG group showed no change while the PDDG showed 0.11 mm of bone gain. At the level of 2 mm ridge width, changes for CBCT analysis for FDBA, MDG, and PDDG were -1.45 mm, -0.20 mm, and -0.11 mm, respectively; for clinical measurements the average bone change for the FDBA, MDG, and PDDG was -1.27 mm, -0.13 mm, and -0.07 mm, respectively. At the level of 4 mm, the average bone change for CBCT analysis for FDBA, MDG, and PDDG was -1.00 mm, -0.16 mm, and 0.13 mm, respectively; for clinical measurements, the average bone change for FDBA, MDG, PDDG was -0.98 mm, -0.04 mm, and 0.05, respectively. Ridge width changes at 2 mm, in both clinical and CBCT measurements were statistically significantly different by gender. Males had more bone loss than Females. No other measurements were significantly different by gender. Changes in 2 mm and 4 mm width measurements on CBCT and in clinical measurements were statistically significant for the group aged 30-50 when compared to > 50 age group. The > 50 age group reported less bone loss in width than the 30-50 age group. There was no statistical difference among graft materials when bone density was analyzed. Conclusion: PDDG and MDG showed less bone loss when compared to FDBA. As a result, PDDG and/or MDG used for ARP are more effective at mitigating dimensional bone volume reduction. Compared to FDBA, autogenous dentin grafts showed more promising results.
