隨著牙醫學的進步，病患對於口腔健康與功能的要求也跟著提高。在各項牙科的治療計畫中，拔牙 往往是不可或缺的一項治療，有時卻因此產生一些併發症。其中乾性齒槽炎是大家所熟知的一種拔牙 後的術後併發症，然而目前為止對於此一病症的致病機轉尚未明瞭。根據文獻回顧可以發現有許多可能 的危險因子與乾性齒槽炎的發生有相關聯性，如：手術性拔牙，施術者的技術，吸菸，病患的性別與年 齡，使用口服避孕藥，以及細菌性感染等。雖然目前治療乾性齒槽炎的方式仍有爭議，但為了減輕病患 的不適，我們必須了解臨床上有何相關處置，更重要的是如何預防，以減少此一併發症的發生，進而降 低醫療成本，而且能避免醫病關係的不信任。(J Family Dent. 7(4): 4-10, 2013 )

With the progress of dentistry, the requests of patients for their oral health and function are getting higher. Tooth extraction is one of the necessary treatments among the dental treatment plan, while some complications are accompanied with it. Dry socket is a well-known postoperative complication following dental extraction. However, the real etiology of this condition is still unclear. Several factors contribute to the occurrence of dry socket have been discussed in many literatures, such as surgical extractions, poor operator's technique, smoking, patient's gender and age, the use of oral contraceptives and bacterial infection. In order to reduce the discomfort of patient and the incidence of dry socket, we have to know the prevention and management although the treatment of this complication is still controversial. Therefore, we can reduce the medical cost and prevent the distrust of patients. ( J. Family Dent. 7(4): 4-10，2013 )
