decreased compared to radiographic exposure of a patient with complete dentition, when exposing periapical radiographs on an edentulous patient, the exposure time should be shielding one of the most effective ways to protect an operator from scattered radiation is shorter exposure time using E speed instead of D speed radiographic film requires longer/shorter exposure time high film density an unsafe safelight will produce a radiograph with low/high film density b...
