[Ionizing radiation absorbed by the patient].
The aim of this study is to evaluate the skin contact dose to which the patient is exposed during an endo-oral radiography using the long cone technique (paralleling technique) and the short cone technique (bisecting angle technique). Measures were taken in 50 dental X-ray units with a range of tension from 50 to 70 Kvs. Measures were taken using a calcium fluoride thermoluminescent dosimeter (CaF2:Dy). Data are expressed in uGy/mA.sec., divided in relation to the tension's values and the kind of technique used. This study reveals that the bisecting technique presents higher doses (2-3 times higher) than the long cone technique (paralleling technique).
