はじめに:
このレトロスペクティブな横断的研究では、コーンビームコンピュータ断層撮影法を用いて、歯内治療歯と上顎洞(MS)異常との関連性を調べるために、歯周周囲および歯内状態尺度(PESS)の適用性を検討した。
INTRODUCTION: This retrospective cross-sectional study investigated the applicability of the periapical and endodontic status scale (PESS) to determine the association of endodontically treated teeth with maxillary sinus (MS) abnormalities through cone-beam computed tomographic imaging.
方法:
合計631本の歯内治療歯を解析した。MS異常は、粘膜肥厚、サイナスポリープ、肛門仮性嚢胞、非特異的閉塞、骨膜炎、肛門石灰化に分類された。歯内療法の質だけでなく、歯周組織の状態を評価するためにPESSを使用した。データはカイ二乗検定によって分析された(P < 0.05)。
METHODS: A total of 631 endodontically treated teeth were analyzed. MS abnormalities were classified as mucosal thickening, sinus polyp, antral pseudocyst, nonspecific opacification, periostitis, and antral calcification. The PESS was used to evaluate the quality of endodontic treatment as well as periapical tissue conditions. The data were analyzed by chi-square tests (P < .05).
結果:
MS異常はサンプルの70.52%で検出され、粘膜肥厚の有病率が38.19%と高かったのに対し、歯周病変は55.94%の症例で観察された。充填、均質性、冠状封鎖が不十分な根管治療例では、オッズ比(OR)はそれぞれ2.21、2.88、2.99であった(P < 0.001)。5mm以上の骨周囲病変(OR = 314.95)、1本以上の歯根(OR = 3.72)、ファーケーション領域(OR = 5.21)、重要な構造物との接触(OR = 7.37)、皮質骨の破壊(OR = 4.09)は、MS異常の存在と有意に関連していた(P < 0.001)。5mm以上の骨膜炎病変では、99,668のORが観察された(P < 0.001)。
RESULTS: MS abnormalities were detected in 70.52% of the sample, with a greater prevalence of mucosal thickening (38.19%), whereas periapical lesions were observed in 55.94% of the cases. Treated root canals with unsatisfactory filling, homogeneity, and coronal sealing had an odds Ratio (OR) of 2.21, 2.88, and 2.99, respectively (P < .001). Periapical lesions larger than 5 mm (OR = 314.95), in more than 1 root (OR = 3.72), involving the furcation region (OR = 5.21), in contact with important structures (OR = 7.37), and with cortical bone destruction (OR = 4.09) were significantly related to the presence of MS abnormalities (P < .001). An OR of 99,668 was observed in periostitis lesions greater than 5 mm (P < .001).
結論:
PESSは、歯内および歯周病変の分析に重要なツールであり、MSの異常との関連性を判断するために適用可能であることが証明された。
CONCLUSIONS: The PESS proved to be an important tool for the analysis of endodontic and periapical conditions and was applicable to determine potential associations with MS abnormalities.
