Influence of dental restoration under general anaesthesia on the low-dose dexamethasone suppression test in dogs.

It was the aim of the study to assess the impact of a minor surgical intervention under general anaesthesia on results of a low-dose dexamethasone suppression test (LDDST) in dogs. Five clinically healthy dogs underwent a LDDST (standard protocol) prior and 1, 4, 7, 14 and 28 days after a dental restoration under general anaesthesia. All LDDSTs revealed negative results.

In a 12-year-old male Labrador Retriever, presented due to other disease symptoms, clinical signs of hyperadrenocorticism (polyuria, polydipsia, abdominal distention, muscle atrophy) were an incidental finding. Abnormal laboratory results and sonographic findings of the adrenal glands, but negative low-dose dexamethasone suppression tests with low basal cortisol concentrations, a negative andrenocorticotropic hormone (ACTH)-stimulation test and exclusion of iatrogenic hyperadrenocorticism, suggested an atypical hyperadrenocorticism (AHAC).
