In the present study, incident air kerma has been measured, for six intraoral examinations, for establishing regional adult diagnostic reference levels (DRLs), in intraoral radiography, in Tamil Nadu, India. A total of 131 units, both digital (semiconductor-based) and analog (film-based) radiography systems, were selected for the study. The third quartile values, for the six intraoral examinations selected for the present study, ranged from 1.2 to 2.0 mGy, for the adult settings. The results showed a wide range of patient doses existing across the clinics or hospitals studied. This is the primary study for the establishment of adult intraoral DRL, in Tamil Nadu, one of the major states of the country. Similar studies will be undertaken in other major states across the country to establish national DRLs in intraoral radiography in the country.
在本研究中，对印度泰米尔纳德邦的六次口腔内检查进行了空气比释动能的测量，以建立区域性成人诊断参考水平（DRL）。本研究共选择了 131 个单位，包括数字（基于半导体）和模拟（基于胶片）放射摄影系统。对于本研究中选择的六次口腔内检查，第三四分位数值在成人设置下范围为 1.2 至 2.0 mGy。结果表明，在所研究的诊所或医院中，患者剂量存在很大差异。这是在该国主要邦之一的泰米尔纳德邦建立成人口腔内 DRL 的首次研究。类似的研究将在该国其他主要邦进行，以在该国的口腔内放射摄影中建立国家 DRL。
