            Statistics presented by NMS GRUPA Ltd. demonstrates that the Trophy ELITYS (25%) (further in text – ELITYS) is the most popular dental x-ray with high frequency and the Trophy IRIX 70 (13%) (further in text  – IRIX 70)  – with half-period generators in Latvia. Time dependent degradation of x-ray machines gives a strong impact on quality of diagnostics. However, there are no data on time dependent degradation. The goal of the study was to explore time dependent behavior of dental x-rays ELITYS and IRIX 70 dose providing parameters such as: 
• X-ray tube voltage [kV]. Quality of this parameter has an influence on a spectrum, image quality, and an absorbed dose. 
• X-ray exposure time [ms] - influences the absorbed dose. 
• X-ray tube output [mGy/mAs] influences the absorbed dose. 
• Air KERMA [mGy] – influences the absorbed dose [1].
