目的:回顾性对比研究X线牙片和锥形束CT在非牙髓治疗牙齿根纵折中的诊断。方法:回顾性对比研究28例32颗非牙髓治疗牙齿根纵折的X线牙片和锥形束CT(Plameca)检查结果。结果:在32颗牙齿中,X线牙片能明确诊断的有24颗牙齿,其中下颌第一磨牙15颗,前磨牙3颗,上颌磨牙近中颊根6颗。8颗上颌磨牙腭根发生根纵折仅靠X线牙片难以诊断,需要锥形束CT检查明确诊断。结论:锥形束CT在非牙髓治疗牙齿根纵折的诊断中明显优于X线牙片。
OBJECTIVE: To retrospectively compare the diagnostic value of X-ray and cone beam CT in non-endodontic tooth root fracture. Methods: A retrospective study of 28 cases of non-endodontic treatment of tooth root longitudinal fold X-ray and cone beam CT (Plameca) test results. Results: Among the 32 teeth, there were 24 teeth that can be diagnosed by X-ray. Among them, 15 were the first molar, 3 were the premolar, 6 were the mesiobuccal root. 8 root maxillary molars palate root longitudinal fold only X-ray diagnosis of difficult to diagnose the need to confirm the diagnosis of cone beam CT examination. CONCLUSION: Cone beam CT is superior to X-ray in diagnosing non-endodontic tooth root fracture.
