目的:探讨锥形束CT(CBCT)结合显微超声技术治疗上颌第一磨牙钙化MB2根管的临床效果。方法:36例经显微根管治疗未疏通的MB2病例的临床资料,采用CBCT扫描、三维重建及测量,明确手术入路,然后采取根管显微超声技术进治疗。结果:36例曾经显微超声治疗未疏通的钙化MB2根管,通过CBCT检测后根管再进行显微超声治疗,共疏通29例,疏通率80.56%。结论:CBCT结合根管显微超声技术能为根管口严重钙化的MB2根管的治疗提供更多信息,有利于促进钙化的MB2根管的疏通。
Objective: To investigate the clinical effect of cone beam computed tomography (CBCT) combined with micro-ultrasonography in the treatment of calcified MB2 root canal in maxillary first molar. Methods: The clinical data of 36 cases with unobstructed MB2 undergoing root canal microkeratography were retrospectively analyzed. CBCT scanning, 3D reconstruction and measurement were performed to confirm the surgical approach. Results: Thirty-six cases of calcified MB2 root canal which had not been treated with micro-ultrasound were examined. After root canal treatment by CBCT, micro-ultrasonography was performed again in 29 cases. The dredging rate was 80.56%. CONCLUSION: CBCT combined with root canal microsurgery can provide more information for the treatment of severely root canal calcified MB2 root canal, which is helpful to promote the calcification of MB2 root canal.
