Strips containing tetracycline hydrochloride or metronidazole 25% in polyhydroxybutyric acid as a biodegradable polymer matrix, showed sustained release in simulated gingival fluid pH 6.6 at 37 degrees C. When evaluated in patients suffering from advanced periodontal disease, the greatest response to therapy was observed with tetracycline hydrochloride strips inserted into periodontal pockets at four-day intervals for 16 days, compared with an untreated control group. A reduction in plaque index, gingival index and pocket depth was observed. A favourable alteration occurred in the microbial flora of treated pockets with an increase in the proportion of cocci and decrease in gram-negative rods, fusiforms and spirochetes. Metronidazole strips or root-planning tended not to be as effective. The clinical improvement produced by each treatment was not maintained when treatment was terminated.

D010518	Periodontitis	Inflammation and loss of connective tissues supporting or surrounding the teeth. This may involve any part of the PERIODONTIUM. Periodontitis is currently classified by disease progression (CHRONIC PERIODONTITIS; AGGRESSIVE PERIODONTITIS) instead of age of onset.

D000287	Administration, Topical	The application of drug preparations to the surfaces of the body, especially the skin (ADMINISTRATION, CUTANEOUS) or mucous membranes. This method of treatment is used to avoid systemic side effects when high doses are required at a localized area or as an alternative systemic administration route, to avoid hepatic processing for example.
