The proximity of the roots to the maxillary sinus can create a variety of risks.
To evaluate the relationship between the roots of healthy teeth and the maxillary sinus, as well as the occurrence of sinus pathologies.
Three radiologists analyzed 109 cone beam computed tomography (CBCT) images. The Kappa test was used to assess the intra- and inter-rater agreement. The chi-squared test and prevalence ratio were used to test the hypothesis that roots of healthy teeth in the maxillary sinus favored the occurrence of sinus pathologies (p=0.01).
Intra- and inter-rater agreement ranged from good to excellent. The chi-squared test demonstrated a statistically significant difference (p=0.006) between the tooth roots in diseased maxillary sinuses (6.09%) and those in normal sinuses (3.43%). The prevalence ratio test showed a statistically significant higher prevalence of tooth roots in diseased sinuses than in normal sinuses (p<0.0001). Roots in the maxillary sinus were 1.82 times more associated with diseased sinuses.
Dental roots in the maxillary sinus are almost twice as likely to be associated with diseased sinuses than normal sinuses. Healthy teeth whose roots are inside the maxillary sinus may induce an inflammatory response in the sinus membrane. It is suspected that dental procedures may exacerbate the condition.
牙根与上颌窦距离较近会产生多种风险。
评估健康牙齿牙根与上颌窦之间的关系以及鼻窦病变的发生率。
三位放射科医生分析了109张锥形束计算机断层扫描（CBCT）图像。采用Kappa检验评估评分者内和评分者间的一致性。使用卡方检验和患病率比来检验上颌窦内健康牙齿的牙根是否更易引发鼻窦病变这一假设（p = 0.01）。
评分者内和评分者间的一致性从良好到优秀不等。卡方检验显示，患病上颌窦中的牙根（6.09%）与正常鼻窦中的牙根（3.43%）之间存在统计学上的显著差异（p = 0.006）。患病率比检验表明，患病鼻窦中牙根的患病率在统计学上显著高于正常鼻窦（p < 0.0001）。上颌窦内的牙根与患病鼻窦的关联度高出1.82倍。
上颌窦内的牙根与患病鼻窦相关的可能性几乎是与正常鼻窦相关可能性的两倍。牙根位于上颌窦内的健康牙齿可能会诱发鼻窦黏膜的炎症反应。怀疑牙科手术可能会使病情加重。
