【摘要】：应用锥形束CT(CBCT)分析上颌后牙根折对上颌窦黏膜的影响,并对上颌窦黏膜炎症反应进行相关性研究。随机选取经CBCT扫描并诊断为一侧根折另一侧无症状的患者50例为实验组,对窦底黏膜厚度,根尖到上颌窦底的距离进行测量,并对数据进行统计学分析。实验组患者根折侧上颌窦黏膜存在增厚改变的发生率为88%,对照侧为2%,差异有统计学意义(P0.05)。在实验组中,根折伴根尖周炎组、根折伴牙周炎组、无其他症状根折组的黏膜厚度,差异无统计学意义。根折患者上颌窦底黏膜容易发生增厚样改变。根折后常伴有根尖周炎、牙周炎等症状,但不同临床症状对上颌窦黏膜厚度影响无差异性。根折牙根距上颌窦底越近,可能更容易对上颌窦黏膜产生影响。
[Abstract]:Cone beam CT (CBCT) was used to analyze the effect of maxillary posterior root fracture on maxillary sinus mucosa, and the correlation between inflammatory reaction of maxillary sinus mucosa was studied. Fifty patients with asymptomatic root fracture were randomly selected as experimental group. The thickness of sinus floor mucosa and the distance from root tip to maxillary sinus floor were measured and the data were statistically analyzed. The incidence of thickening of maxillary sinus mucosa in the experimental group was 88%, and that in the control side was 2%, the difference was statistically significant (P 0.05). In the experimental group, there was no significant difference in the thickness of mucous membrane in the root fracture with periapical inflammation group, the root fracture with periodontitis group and the non-symptomatic root fold group. The maxillary sinus floor mucosa in patients with root fracture is prone to thickening-like changes. Root fracture is often accompanied by periapical inflammation, periodontitis and other symptoms, but there is no difference in the thickness of maxillary sinus mucosa with different clinical symptoms. The closer the root of the root is to the floor of the maxillary sinus, the more likely it may be to have an effect on the mucosa of the maxillary sinus.
