目的研究辐射特殊环境对工作人员唾液流率的影响,为其口腔疾病预防与治疗提供依据。方法以现场调查的方式对341名长期直接从事低剂量辐射接触工作的人员上午8:00～10:00时进行安静状态和刺激状态唾液流率检测,要求所有被检测者检查前8h不刷牙漱口,空腹。获得数据利用FoxPro6.0软件建立数据库,SPSS16.0软件进行统计分析。结果 341名长期接触低剂量辐射工作人员刺激唾液流率明显高于安静唾液流率[(0.311±0.231)vs(0.815±0.501)ml/min,P<0.05],但两项流率均低于文献报道的普通健康人群测量值。结论长期低剂量慢性辐射在某种程度上对人唾液腺有一定的损伤。安静唾液流率和刺激唾液流率作为人口腔唾液腺分泌功能的重要指标,可以反映长期低剂量辐射对涎腺功能的影响程度,同时也可为临床诊断和治疗提供参考。
Objective To study the influence of radiation special environment on saliva flow rate in workers and provide basis for the prevention and treatment of oral diseases. Methods A total of 341 long-term personnel working in low-dose radiation exposure who were exposed to radiation for a long period of time were investigated by field survey in the state of quiescence and stimulation of salivary flow at 8: 00-10: 00. All subjects were asked not to brush their teeth before checking for 8h Mouth, fasting. Access to data using FoxPro6.0 software to establish a database, SPSS16.0 software for statistical analysis. Results The results showed that the salivary flow rate of 341 long-term exposed low-dose radiation workers was significantly higher than that of quiet salivary flow [(0.311 ± 0.231) vs (0.815 ± 0.501) ml / min, P <0.05] The reported average health population measurement. Conclusion Long-term low-dose chronic radiation to some extent, the human salivary glands have some damage. Quiet saliva flow rate and stimulation of salivary flow rate as an important indicator of oral salivary gland secretion can reflect the long-term low-dose radiation on salivary gland function, but also can provide a reference for clinical diagnosis and treatment.
