口腔检查涉及到多个项目,所应用的检查手段也较多,而口腔X检查便是其中一种检查手段。口腔诊断过程中,单次应用口腔X照射剂量所引发的危害性极低,但是若反复使用将其累计后所形成的危害性就必须要受到重视。尤其是近几年口腔疾病逐渐增多,口腔X检查也越来越受到广泛的应用,而其危害性也引起了临床医学界的关注,多数研究学者对此展开研究,呈现出诸多研究资料。本文中将对近几年口腔X检查相关研究资料进行查阅,总结口腔X检查放射防护的最新研究方向。 Oral examination involves a number of projects, the application of more means of inspection, and oral X-ray examination is one of the means of inspection. During the oral diagnosis, the single dose of oral X-irradiation caused by the very low hazard, but if repeated use of its cumulative harm after the formation must be taken seriously. Especially in recent years, oral diseases are gradually increasing, oral X-ray examination is also more and more widely used, and its harmfulness has aroused the concern of the clinical medical profession. Most of the researchers have studied and presented many research materials. In this paper, oral X-related research data will be reviewed in recent years, summarizing the latest research direction of oral X-ray radiation protection.
