The proximity of the roots of maxillary posterior teeth to the maxillary sinus floor can be associated with the development of chronic maxillary sinusitis (CMS). Therefore, this study evaluated the correlation between the presence of endodontic infection and periodontal disease in maxillary posterior teeth and the presence of CMS.
A total of 83 patients (159 maxillary sinuses) were selected and underwent clinical dental examination to assess tooth mobility and pulp condition. In addition, cone-beam computed tomography was performed to evaluate the presence of periapical lesion and periodontal bone loss, and measure the distance from the root apex to the cortical of the maxillary sinus. The maxillary sinuses were divided into 2 groups: CMS and no maxillary sinusitis. Data were analyzed using χ test and binary logistic regression analysis (P < .05).
Periodontal disease was positively associated with CMS, leading to a 3.45-fold higher association between these disorders (P < .05). CMS was significantly more common in patients with periodontal disease or endodontic infection in close proximity with the maxillary sinus. Periodontal disease or endodontic infection that was more distant from the maxillary sinus was more common in patients with no maxillary sinusitis (P < .05). To the extent that the tooth is more distant from the maxillary sinus floor, the chance of presenting CMS is reduced up to 2.5-fold (P < .05).
Periodontal disease and proximity to the maxillary sinus are more common in cases of CMS, requiring a dental assessment and cone-beam computed tomography evaluation in patients with CMS with ineffective treatment.
上颌后牙的根部与上颌窦底的接近程度可能与慢性上颌窦炎（CMS）的发生有关。因此，本研究评估了上颌后牙牙髓感染和牙周病的存在与 CMS 的相关性。
共选择 83 例患者（159 个上颌窦），进行临床牙科检查以评估牙齿松动度和牙髓状况。此外，还进行了锥形束计算机断层扫描，以评估根尖周病变和牙周骨丢失的存在，并测量根尖到上颌窦皮质的距离。上颌窦分为 2 组：CMS 和无上颌窦炎。使用 χ 检验和二元逻辑回归分析（P<.05）对数据进行分析。
牙周病与 CMS 呈正相关，导致这两种疾病之间的关联增加了 3.45 倍（P<.05）。牙周病或接近上颌窦的牙髓感染的 CMS 更为常见。远离上颌窦的牙周病或牙髓感染在无上颌窦炎患者中更为常见（P<.05）。上颌窦底越远，出现 CMS 的机会就会降低多达 2.5 倍（P<.05）。
牙周病和接近上颌窦在 CMS 病例中更为常见，对于治疗无效的 CMS 患者，需要进行牙科评估和锥形束计算机断层扫描评估。
