Abstract:

目的对比研究锥形束CT与曲面体层片在诊断上颌阻生尖牙邻近切牙根吸收的差异。方法对46例上颌阻生尖牙患者拍摄曲面体层片和锥形束CT片,比较这两种方法对阻生尖牙邻近切牙根吸收程度的诊断率。结果曲面体层片对上颌阻生尖牙邻近切牙根吸收诊断的灵敏度为37.5%,特异度为94.1%,误诊率为5.9%,漏诊率为62.5%,正确度为76.0%。曲面体层片和锥形束CT片在诊断切牙根吸收上的一致性差(Kappa值=0.364)。结论锥形束CT能清晰显示上颌阻生尖牙邻近切牙的根吸收程度,曲面体层片对上颌阻生尖牙邻近切牙根吸收的诊断存在漏诊,对存在上颌阻生尖牙的病例,建议应用锥形束CT来辅助诊断,以避免漏诊。
