Bone and tissue regeneration with chitosan membrane a case report

Guided bone and mucous membrane regeneration (GBR) using membranes of chitosan, excludes gingival epithelial cells and connective healing, promoting regeneration through active and proper ordering of the regenerated tissue. Objective: To evaluate clinical, cytological and radiographic bone and mucous injury treated with chitosan membrane. Methods: Female patient 18 years old, which systemically healthy subjects underwent surgery retained mandibular third molars. For the GBR was hydrated chitosan membrane in saline, and covered her right socket. At 8 days, suture removal and cytology was performed in both areas. Photographs were taken at 15 days and a month. Panoramic radiographs were also performed at 15 days, months and 7 months postoperative. Results: After eight days left side was observed with wound dehiscence, food packaging, while on the right side was lower the degree of swelling and erythema, better healing and scarce accumulation of plaque. Mucosal month on the right side showed signs of healing optimal, while left plaque accumulation persisted. Radiographically, after 15 days, on the right side was observed continuity of the surgical site with the surrounding bone mineral apposition and scarce. A month mineral density was moderate (50 and 80% of default). At 7 months postoperatively was abundant mineral apposition (greater than 80%). The Pap smear Class I on the right side showed isolated portions of the chitosan membrane detached, few isolated epithelial elements, without evidence of inflammatory components. Conclusion: Our results indicate that the alveolus treated with chitosan regenerated faster and the inflammatory process was less aggressive than in the untreated side.
