Tetracycline, metronidazole, and chlorhexidine have been tested for their effectiveness in the treatment of periodontitis in dogs under experimental conditions. Tetracycline has been effective in reducing bone resorption in dogs with periodontitis when used in the long-term. When used for short times, it can result in reduction of the numbers of microorganisms that are associated with disease. Tetracycline can inhibit the activity of mammalian collagenase thought responsible for the destruction of alveolar bone and it may be capable of inhibiting the adherence of microorganisms and thus preventing infection. In some experiments, metronidazole was more effective than tetracycline in eliminating spirochetes from the periodontal flora, and it has been found effective in preventing the inflammation and the development of the bacterial flora usually associated with the natural accumulation of plaque. Chlorhexidine (0.2% aqueous solution) has been found effective in preventing the normal progression of periodontal disease when used as a spray for the long-term treatment of dogs. It could prove to be as effective as brushing for the long-term control of periodontitis in the dog. Limited information is available on the use of clindamycin, spiramycin, and vancomycin.
