The post shows a set of properly-oriented and presented intra-oral dental radiographs of a 30 kg dog. It can act as an example of what you should be striving for when taking intra-oral dental radiographs and to show owners what normal/healthy looks like to compare to the images of their pet who may have disease.
An example of a good, whole-mouth radiographic study in a cat with no detectable pathology. You can use these as an exemplar of what you should be striving for when radiographing your feline patients and to show owners what normal/healthy looks like when explaining to them the issues that their pet has.
