Abstract：
OBJECTIVE: The study aimed to investigate the sinus membrane thickness (SMT) adjacent to healthy endodontically-treated maxillary molars with or without protruded apical foramen into the sinus cavity using cone-beam computed tomography (CBCT).
METHODS: Images of 207 non-smoker patients aged 18-40 were retrospectively analyzed, 140 were endodontically treated, and 136 were without endodontic treatment. Patients with any sinus pathology, teeth that have symptoms, or poor root filling were excluded. Study groups consisted of Group EM-I (endodontically treated and protruded apical foramen), Group EM-C (endodontically treated and contacted apical foramen), and similarly without endodontic treatment; Group M-I and Group M-C. SMT upon the mesial, distal, and palatal roots was measured. One-way ANOVA and Student\'s t-tests were performed.
RESULTS: Group EM-I had the thickest sinus membrane compared to other groups (p = 0.013). SMT values were 2.37-2.60 mm in Group EM-I, and 1.34-1.58 mm in other groups. Thickening (> 2 mm) percentages were 33.45% in Group EM-I and between 4.25 and 8.25% in other groups. No statistical difference was detected between first and second molars and genders (p > 0.05).
CONCLUSIONS: When the apical foramen protruded into the sinus cavity, the conventional root canal treatment caused a minimal (between 2.37 mm and 2.60 mm) sinus membrane thickening with a rate of 33.45% based upon CBCT examinations.

摘要：
目的：该研究旨在使用锥形束计算机断层扫描（CBCT）研究健康牙髓治疗的上颌磨牙附近有或没有根尖孔突出进入窦腔的窦膜厚度（SMT）。
方法：回顾性分析207名18-40岁非吸烟者的图像，140人接受了牙髓治疗，136例未经牙髓治疗。有任何鼻窦病变的患者，有症状的牙齿，或根性欠佳被排除。研究组由EM-I组（经牙髓治疗和根尖孔突出）组成，EM-C组（经牙髓治疗并接触根尖孔），同样没有牙髓治疗；M-I组和M-C组SMT在中间，远端,测量腭根。进行单因素方差分析和学生t检验。
结果：与其他组相比，EM-I组的窦膜最厚（p=0.013）。EM-I组中SMT值为2.37-2.60mm，和1.34-1.58毫米其他组。在EM-I组中增厚(>2mm)百分比为33.45%,在其他组中介于4.25和8.25%之间。第一磨牙和第二磨牙及性别间无统计学差异(p>0.05)。
结论：当根尖孔突入窦腔时，根据CBCT检查，常规根管治疗引起的窦膜增厚最小（在2.37mm至2.60mm之间），率为33.45％。
