The radiographic detection of periapical lesions in dogs

The study investigated the correlation between the radiographic and histologic examinations of periapical lesions in dogs. The roots of four dogs were examined 3 months after root fillings had been placed and those of two dogs 1 year after placement of root fillings. Overall, as the extent of inflammation increased so did the size of the radiographic lesions, but there was some disagreement between methods, particularly in the detection of normal apices. The examination of radiographs could not be regarded as a substitute for histologic examination.
