Radiation dosage of a dental imaging system.
This study compared the radiation dosage necessary for obtaining clinically acceptable images with a new dental imaging system (radiovisiography) to that required with a conventional-film radiographic technique. Results showed that radiovisiography required significantly less radiation exposure, only 22.3% of that used in the conventional technique. Problems, such as lack of flexibility and the limited size of the x-ray-sensitive surface, are associated with radiovisiography; however, the system effectively complements conventional-film radiography.
