目的:分析锥形束CT(CBCT)辅助诊断慢性根尖囊肿累及范围的临床应用效果。方法:选取2013年4月-2014年4月诊断为慢性根尖囊肿的CBCT三维重建影像资料42例,观察X线根尖片及CBCT三维重建影像资料,综合评价CBCT在辅助诊断慢性根尖囊肿累及范围中的应用效果。结果:CBCT诊断慢性根尖囊肿累及范围的能力显著优于X线根尖片,42例均能通过CBCT准确诊断囊肿累及患牙,并于根管治疗后根尖囊肿如期愈合。结论:CBCT能够辅助诊断慢性根尖囊肿的累及范围,并指导临床医生判断受累患牙。
Objective: To analyze the clinical application of cone beam computed tomography (CBCT) in the diagnosis of chronic apical cyst. Methods: Forty-two patients with chronic apical cyst diagnosed as chronic apical cyst from April 2013 to April 2014 were enrolled in this study. 42 cases of CSPT three-dimensional reconstructed images were observed. Involved in the application of the effect. Results: The ability of CBCT to diagnose chronic apical cyst was significantly better than that of X - ray. CBCT could accurately diagnose the involvement of cyst in 42 cases, and apical cyst healed after root canal therapy. Conclusion: CBCT can help diagnose the scope of chronic apical cyst and guide the clinician to judge the involved teeth.
