摘要： 目的：观察硫酸钙、β-TCP（β-磷酸三钙）及生物玻璃（倍骼生）在颌骨囊肿治疗中的疗效。方法：颌骨囊肿病例45例，行囊肿刮除术后，随机分为4组，骨腔内填充不同物质。A组：硫酸钙组；B组:β-TCP组；C组：生物玻璃（倍骼生）组；D组：空白组。术后观察患者术区肿胀程度，且1、3、6、12个月后拍摄CBCT或全景片，观察术区骨愈合情况。结果：A组患者术后1周内术区肿胀明显； A、C组患者6个月后，术区与正常骨组织无明显区别；B组患者12个月后，新骨几乎充填整个骨腔；D组新骨形成明显较A、B、C组慢。结论：在新骨形成方面，A、B、C组分别与D组相比，差异均有统计学意义；硫酸钙会引起部分患者术区肿胀反应。

Abstract: Objective: To observe the different effect of medical calcium,β-tricalcium phosphate（β-TCP）and Perioglas in the treatment of odontogenic cysts cavities. Methods: Screen 45 cases of jaw cyst randomly. After cyst curettage operation, according to the different bone cavity filling materials, these cases divided into four groups, Group A: Medical calcium; Group B: Calcium phosphate; Group C: Perioglas; Group D: Blank group. Observations included the swelling degree of surgical site; Regular x-ray examination was performed at 1, 3, 6, 12 months intervals to realise the bone regeneration. Results: In group A， the swelling of surgical site was obvious after operation. In group A and group C， after 6 months of operation, there was no significant difference between the operative region and surrounding normal bone tissue. Group B: 12 months later, the material was completely absorbed, and the new bone was almost filled with the whole bone cavity. Group D: The rate of the new bone formation was significantly retarded  than that of A, B, and C groups. Conclusion: Comparison between group A, B, C and group D, the rate of new bone formation differed significantly. Medical calcium sulfate could cause swelling reaction in the operation area.

Key words: Medical calcium sulfate, β-tricalcium phosphate, Perioglas, jaw cyst, bone defect repair
