Evaluation of The Effectiveness of Using Calcium Sulfate Hemihydrate Graft for Socket Preservation after Teeth Extraction

Background: The protection of the socket absorption followed by teeth extraction is one of the most essential matters, as it facilitates the next implantation process and gives better functional and cosmetic results. Therefore, many methods were used to preserve the socket absorption, including bone grafts, which is the most available and less expensive material. Aim of Study: to evaluate the effectiveness of calcium sulfate in reducing bone absorption and preventing alveolitis after teeth extraction. Materials & Methods: 24 teeth were extracted; 12 sockets were immediately grafted with Calcium Sulfate after extraction however, 12 sockets were left to heal spontaneously without adding any material. In both groups, the horizontal bone absorption of the crestal bone was evaluated 6 months after the extraction using CBCT technique. The occurrence of alveolitis was evaluated clinically. Results: Radiographic results after 6 months showed that the average of horizontal bone absorption in the study sample was (0,575± 0.24) mm, and the absorption rate was (8.5%) while in the control group (without Bone graft) the average of horizontal bone absorption was (1,483± 0.65) and the absorption rate was (22.7%). The incidence of alveolitis in the study group was (0%), while it was 41.7% in the control group. Conclusion: The application of calcium sulfate grafts after extractions reduces dimension changes in the alveolar bone at the horizontal level, but doesn't prevent its occurrence. On the other hand, it can prevent the occurrence of post-extraction Alveolitis.
