The aim of this study is to assess the evaluation of radiation protection principles observance in dental radiography centers and hazards. This cross-sectional study was designed to assess level of radiation protection principles in dentistry centers. The present cross-sectional study was conducted by enrolling 103 dentistry centers in Kermanshah province (west of Iran). Our finding illustrates 75.7% of the centers were equipped with an intraoral radiography. Although observance principles of radiation protection for patient at dentistry center were at appropriate level (97.3%), the observance of the protective principles was not adequate for the skilled workers in any center. The most commonly used protective measure was the observance of a distance from patient (97.3%) and the minimum protective measures such as the use of high-speed film (1.4%). According to results in this study, the knowledge and practice of radiation protection are not satisfactory.

牙科放射照相中心放射防护原理遵守情况的评估（伊朗西部）：横断面研究。

这项研究的目的是评估牙科放射照相中心和危害的放射防护原则遵守情况的评估。这项横断面研究旨在评估牙科中心的辐射防护原理水平。目前的横断面研究是通过招募位于伊朗西部的克曼沙赫省的103个牙科中心进行的。我们的发现表明75.7％的中心配备了口内放射照相。尽管牙科中心对患者的辐射防护遵守原则处于适当水平（97.3％），但对于任何中心的技术人员而言，对辐射防护的遵守都不够。最常用的保护措施是遵守与患者的距离（97.3％），最小的保护措施是使用高速胶卷（1.4％）。
