2种术式拔除下颌阻生第三磨牙术后干槽症及其发生机制探讨
Influence of Different Surgical Procedures on the Incidence of Dry Socket after Impacted Mandibular Third-Molar Extraction
摘要
Abstract
Objective To discuss the etiology and prophylaxis measures of dry-socket. Methods A total of 4 897 eases of mandibular impacted third molar were randomly divided into two groups, 2 284 cases in the group I were performed extraction by knocking chisel, while 2 613 cases in the group 2 were applied with extraction with turbine. The incidences of dry-socket were observed among these cases in both groups. Results The 87 cases of dry-socket were found in the group 1, and the incidence of dry-socket was 3.81％. No dry-socket was found in the group 2. The incidence of dry socket was significantly different between these two groups (χ2 = 101. 332, P ＜ 0. 05). Conclusion The dry socket may be resulted from necrosis of the alveolar bone due to the compression when the extraction is performed by knocking chisel. The alveolar bone will not be compressed and dry socket can be prevented if the teeth are extracted with turbine.关键词
