[Beagle dogs in periodontal research: a review]

This review intends to focus on the role dogs play in periodontal research. Dogs have given insight in the occurrence, the etiology, the pathogenesis and the treatment of periodontal diseases although some differences with humans exist. The occurrence of root resorption, the better healing capacity and the progression rate of periodontitis are among those differences. Knowledge of the periodontal conditions in dogs is required to be able to evaluate the obtained results and its implications for humans carefully. This seems especially true for the ongoing research in tissue regeneration.
