接触酸作业者牙酸蚀病损情况调查分析

Investigation of the situation of dental erosion in people with acid contact

目的调查分析本地区接触酸作业者的牙酸蚀病损情况,为牙酸蚀病的防治提供依据。方法对本地某企业工人进行口腔专项健康调查,随机选取45例接触酸作业工人作为观察组,同时随机选择45例非接触酸工种的工作人员作为对照组,比较两组工人牙酸蚀病的发生情况。结果 45例接触酸作业工人中有15例出现牙酸蚀病损,发生率为33.3%;45例非接触酸作业工者中有2例出现牙酸蚀病损,发生率为4.44%,观察组牙酸蚀病损发生率明显高于对照组(x^2=12.256 2,P<0.05)。结论接触酸作业者牙酸蚀病损发生率明显增高,应通过加强个人防护、定期轮换工作岗位等方式对牙酸蚀病损进行有效预防。

Objective To investigate and analyze the situation of dental erosion in people who have contact with acid ,in order to provide information for the prevention of dental erosion .Methods Oral health of staff in an enterprise were investigated ,and 45 staff who contacted acid were chosen randomly to be the observation group , and another 45 staff who didn＇t contact acid were chosen randomly to be the control group .Dental erosion in the two groups was compared .Results As many as 15 people in the observation group had dental erosion （33 .3% ） , and 2 in the control group had dental erosion （4 .44% ） .There was significant difference between the two groups （χ2 =12 .256 2 ,P〈0 .05） .Conclusions The rate of dental erosion in people who contacted acid was markedly in-creased .Personal protection ,job rotation and other methods should be taken to prevent the incidence of dental ero-sion .
