Abstract

Periodontitis is a chronic infection in the supportive tissue of the teeth which eventually leads to tooth loss. Various grafting materials and barrier membranes have been used to repair periodontal intraosseous lesions. Chitosan is a derivative of chitin, a natural biopolymer, which is biologically safe, biodegradable, and nontoxic and has been applied in a variety of forms in dentistry. It also exerts bioactive properties such as wound healing, antimicrobial, tissue regeneration, and hemostatic activities. The aim of this study was to evaluate effects of chitosan on periodontal regeneration. Twenty chronic periodontitis patients were recruited. Following initial therapy, the patients were divided into four groups: group A, receiving chitosan gel (1% w/v); group B, receiving chitosan gel + demineralize bone matrix; group C: receiving chitosan gel + collagenous membrane; and group D, receiving nap only (control group). Clinical and radiographic measurements were recorded at baseline, day 90 (3rd month), and day 180 (6th month) after surgery. For clinical data, no significant differences were obtained among the treatment groups. However, radiographic data revealed that except control group, all the other groups showed statistically significant bone rills when compared with baseline indicating that chitosan gel alone or its combination with demineralize bone matrix/collagenous membrane is promising for periodontal regeneration.
