A clinical and microscopical (SEM) investigation has been carried out on the biocompatibility of cellulose acetate fiber tetracycline with 25% of tetracycline hydrochloride (Actisite R). A subject with advanced periodontal disease was selected and a pocket of 8 mm of PD was chosen. A segment of fiber was inserted into the pocket for 8 days. After removal, PD and GI clinical parameters were detected and the fiber removed was analyzed at the scanning electronic microscope. The results showed clinical signs of inflammation after removal of fiber. SEM analysis showed macrophagic reaction, a typical sign of inflammatory response to material. The study suggests the need of more biocompatible materials, easier to use as delivery system of antibiotics in the treatment of periodontal disease.

Abstract
A clinical and microscopical (SEM) investigation has been carried out on the biocompatibility of cellulose acetate fiber tetracycline with 25% of tetracycline hydrochloride (Actisite R). A subject with advanced periodontal disease was selected and a pocket of 8 mm of PD was chosen. A segment of fiber was inserted into the pocket for 8 days. After removal, PD and GI clinical parameters were detected and the fiber removed was analyzed at the scanning electronic microscope. The results showed clinical signs of inflammation after removal of fiber. SEM analysis showed macrophagic reaction, a typical sign of inflammatory response to material. The study suggests the need of more biocompatible materials, easier to use as delivery system of antibiotics in the treatment of periodontal disease.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
