摘要

臨床上，由於上顎後牙牙根和鼻竇的解剖結構距離很近，牙髓與根尖的病變可能擴散造成上顎鼻竇炎。本次病例報告為上顎第二小臼齒根尖周圍炎（apical periodontitis）引起上顎鼻竇黏膜增厚（maxillary sinusmucosal thickening），在進行非手術性根管治療後，藉傳統X光評估，顯示得到立即改善。本文藉由討論錐束電腦斷層（cone-beam computed tomography）在鼻竇黏膜增厚的研究，探討其盛行率、分類、根管治療處理方式，與根尖病灶跟黏膜增厚的相關性。

Clinically, maxillary sinusitis might be caused by odontogenic infection, due to the close proximity of the roots of the maxillary posterior teeth and the maxillary sinus cavities. This case report presents the apical periodontitis of maxillary second premolar which induced maxillary sinus mucosal thickening. After nonsurgical endodontic treatments, the immediate improvement was found by the evaluation of conventional X ray. We review the prevalence, classification and treatment considerations of sinus mucosal thickening by cone-beam computed tomography, and the associations between periapical lesions and sinus mucosal thickening.
