To evaluate the images obtained by CT in diagnosis and treatment plan of teeth in the maxillary sinus.
Twelve patients with teeth in the maxillary sinus were studied by plain film radiography (PFR) and by CT with a dental software programme, which displays multiple panoramic and cross-sectional views of the mandible and maxilla. The three-dimensional morphology of the tooth, its inclination, proximity to the sinus wall, surgical planning and prediction of prognosis and complications were estimated on both PFR and on CT scans and scored.
The radiographical features interpreted from PFR were fair or poorly diagnosed whereas CT provided excellent features. The surgical approach of choice was based on CT interpretation.
CT is useful for diagnosis and treatment planning of teeth in the maxillary antrum.
评估CT在上颌窦牙齿诊断及治疗计划中的应用图像。
对12例上颌窦内有牙齿的患者进行了平片X线摄影（PFR）以及使用牙科软件程序的CT检查，该软件程序可显示下颌骨和上颌骨的多个全景和横断面视图。在PFR和CT扫描上对牙齿的三维形态、倾斜度、与窦壁的接近程度、手术规划以及预后和并发症预测进行评估并评分。
PFR所解读的影像学特征诊断效果一般或较差，而CT提供了出色的特征。首选的手术方法基于CT解读。
CT对上颌窦内牙齿的诊断和治疗计划有用。
