The Effect of Chitosan Gel 15% in the Surgical Treatment of Stage III Periodontitis: A Case Report of Two Cases.

Periodontal diseases are widely spread, particularly in adults. Chitosan has non-toxicity and biocompatibility properties, as it has been studied in many studies in various surgical applications. This case report includes two female patients (aged 23 and 48) who were treated by the application of Chitosan gel 15% during open flap debridement in an aggregate of 26 periodontal pockets. Several clinical measurements were evaluated (probing depth, gingival recession, and bleeding on probing) for the treated periodontal pockets, between two periods, the first in baseline and then after six months. The results showed a reduction in probing depth of (3.30±0.27) after six months. The bleeding on probing also decreased from 84.61% to 0%. This case report concluded that the application of Chitosan gel 15% reduced pocket depth and bleeding on probing when applied in open flap debridement.
