Abstract
According to data published by the National Commission of Nuclear Energy (CNEN) it was observed that in Dental Radiology more than 80% of the exams reveal entrance skin doses higher than 5,0 mGy, that proximately 85% of the dentists sub-develop the films and 40% of the equipment have low performance regarding collimation, filtration and other problems. This is a critical situation for the population regarding life quality and requires prompt attention from the sanitary authority. Face and universe of 30,000 dentist in the state of Sao Paulo, it was necessary to organize a technical and administrative structure to establish procedures, elaborate training course and create an adequate software system to control all the inspections. The inspection control was based on monitoring the geometrical and exposure parameters as well as the implementation of internal procedures. It was also implemented a control of reject rate and a routine check of the control books. Results show a great improvement of the parameters in 152 of the x ray tubes considered here. Entrance skin dose up to 2,5 mGy increased from 19% to 57%, field size up to 6 cm, increased from 33 % to 96%, k Vp exactitude (13%) and exposure time (67%)

Also 100% were attained with regards to filtration, collimation and several internal procedures. By the results showed above, we can conclude that we are in the right directionand that all goals will be reached.}
