Abstract
This study was conducted for evaluation of the radiographic bone changes following socket preservation in mandibular molars using deproteinized bovine bone mineral versus using Beta tri calcium phosphate. Fourteen candidates (5 males, 9 females), suffering from non-restorable teeth and seeking implant rehabilitation, were selected from the outpatient they were divided into two groups. group A Control group who use deproteinized bovine bone mineral group B study group who use beta tri calcium phosphate. All the cases were evaluated using cone-beam computed tomography (CBCT) before extraction and 6 month postoperative. Socket width changed In group A: the mean socket width changed from 9.82±0.64 before extraction to 8.78±0.84 mm at 6 months postoperative, this was statistically significant p<0.001 In group B: the mean socket width changed from 10.2±0.66 before extraction to 8.19±0.94 mm at 6 months postoperative, this was statistically significant p=0.001 Socket height changed In group A: the mean socket height changed from 26.15±3.58 before extraction to 24.1±3.21 mm at 6 months postoperative, this was statistically significant p<0.001 In group B: the mean socket height changed from 25.86±4.3 before extraction to 23.32±3.43 mm at 6 months postoperative, this was statistically significant p=0.001 Mean socket width percent reduction of group A was 10.73± 3.71 % compared to 19.85±6.35% in group B. This was statistically significant while the mean socket height percent reduction of group A was 7.77± 2.79 % compared to 9.59±2.95% in group B. This was statistically not significant
