摘要: 目的 评价口腔曲面体层片判断上颌牙根突入上颌窦的敏感度与特异度。方法 纳入110例患者,男42例,女68例;年龄15~36岁,上颌第二磨牙已完全萌出,拍摄全牙列锥形束CT(CBCT)及口腔曲面体层片。分别根据2种影像数据观察上颌尖牙、上颌第一前磨牙、上颌第二前磨牙、上颌第一磨牙及上颌第二磨牙牙根是否突入上颌窦。以CBCT观察结果为金标准,收集四格表资料,计算口腔曲面体层片进行判断的敏感度、特异度、准确度、阳性似然比、阴性似然比及牙根进入上颌窦的发生率。结果 口腔曲面体层片判断牙根是否突入上颌窦的敏感度分别为上颌尖牙100%,上颌第一前磨牙100%,上颌第二前磨牙96%,上颌第一磨牙99%,上颌第二磨牙96%。特异度分别为上颌尖牙94%,上颌第一前磨牙92%,上颌第二前磨牙84%,上颌第一磨牙55%,上颌第二磨牙67%。结论 口腔曲面体层片判断上颌牙根是否进入上颌窦的敏感度高,但是对于第二前磨牙、第一磨牙及第二磨牙判断的特异度较低。正畸临床不能以之作为上颌后牙支抗设计的依据。

Abstract: PURPOSE: To evaluate the diagnostic sensitivity and specificity of panoramic radiography in detection of maxillary teeth roots projecting into the maxillary sinus. METHODS: Paired panoramic radiographs and cone-beam CT (CBCT) images of maxilla from 110 subjects were analyzed. 42 males and 68 females (15~36 years old) with the second molars erupted completely were included. The 2 radiographic techniques were used to observe if the roots of maxillary teeth project into the sinus, including canine, the first premolar, the second premolar, the first molar and the second molar. With CBCT as a gold standard, the diagnostic sensitivity and specificity of panoramic radiography were evaluated, as well as the accuracy, prevalence, positive likehood ratio, and negtive likehood ratio. RESULTS: The sensitivity for canine, the first premolar, the second premolar, the first molar, and the second molar was 100%, 100%, 96%, 99%, and 96%, respectively. The specificity for canine, the first premolar the second premolar, the first molar, and the second molar was 94%, 92%, 84%, 67%, and 67%, respectively. CONCLUSIONS: Panoramic radiography has a high diagnostic sensitivity in detection of the teeth roots projecting into the maxillary sinus for maxillary teeth. However, it can't afford sufficient proof for orthodontic anchorage design because of low specificity, especially for the second premolar, the first molar and the second molar.
