本文对４３名矽肺患者口腔状况进行调查。结果发现，矽肺患者口腔状况较差，ＤＭＦＴ为１１．７，平均缺失牙８．９颗，患牙龈炎伴牙结石、牙周袋大于５ｍｍ牙的百分比为１１．３。４３名矽肺患者均存在牙磨损，牙磨损严重程度显著高于对照组（Ｐ＜０．０５或０．０１），且牙磨损多见于切牙和磨牙。牙磨损罹患率与接尘工龄呈正相关（Ｐ＜０．０１）。提示矽肺患者牙磨损与职业接触石英粉尘密切相关。 This article investigated the oral status of 43 patients with silicosis. The results showed that patients with silicosis poor oral status, DMFT was 11.7, an average of 8.9 missing teeth, with gingivitis with calculus, periodontal pocket greater than 5mm teeth percentage of 11.3.43 patients with silicosis are present Tooth wear, the severity of tooth wear was significantly higher than the control group (P <0.05 or 0.01), and tooth wear more common in incisors and molars. There was a positive correlation between dental wear rate and the age of dust-pick-up (P <0.01). Tip silicosis patients with dental wear and occupational exposure to quartz dust are closely related.
