胃食管反流病患者牙齿表面缺损的定量研究

摘要

目的 本研究测量胃食管反流病患者牙齿数字模型的轮廓变化,为胃食管反流病患者牙体硬组织的定量变化提供临床依据.方法 胃食管反流病和正常人群各15名,分别制取0和6个月数字模型,比较牙齿表面形态变化.结果 胃食管反流病患者和正常人群各15名,其中1名胃食管反流病患者失访,共580颗牙齿纳入研究.胃食管反流病患者平均牙齿表面硬组织缺损(12.07 ± 1.85)μm高于正常人群组(3.23 ± 0.48)μm,牙齿硬组织缺损量与胃食管反流病相关(t=3.193),在胃食管反流病患者中,牙齿的咬合面、腭/舌面硬组织缺损量大于颊面.结论 6个月临床观察发现胃食管反流病患者的牙齿表面硬组织缺损量大于正常人群.在胃食管反流病患者中,牙齿的咬合面、舌/腭面硬组织缺损量大于颊面.%Objective To evaluate the association between tooth surface loss and gastroesophageal reflux disease (GERD). Methods The dental impression was obtained from 15 patients with GERD and 15 controls at baseline and six months.The tooth surfaces of these replicas were digitized using an optical scanner. The depth of tooth surface loss was recorded after matching the digitized model at baseline and six months. The association between GERD and the depth of tooth surface loss was evaluated. Results One patient was lost to follow-up and the other 29 participants(580 teeth) were included. The tooth surface loss in patients with GERD(12.07 ± 1.85 μm) was more than that in the control(3.23 ± 0. 48 μm). The tooth surface loss was associated with GERD (t=3.193). The tooth tissue loss on palatal and occlusal surface was more than that on buccal surface in patients with GERD. Conclusion The tooth surface loss in patients with GERD was greater than that in the healthy controls.
