Chemotherapy in the treatment of periodontopathy

We treated 27 patients suffering from periodontitis with 750 mg/d oxytetracycline over a fortnight and compared them with a control group of 25 patients who received only a placebo. The selection of patients followed certain criteria. For controlling of the success of treatment, we developed a simple model of clinical and microscopical parameters. A significant difference between both groups could be demonstrated six months after starting the treatment.
