Evaluation of Bovine-Derived Collagen Membrane in Oral Surgical Mucosal Defects.

Background: The overall purpose of this clinical study is to evaluate the effectiveness of bovine-derived collagen in surgical oral mucosal defects.

Patients And Methods: The study model included thirty-two patients who underwent surgery for benign and malignant lesions of oral cavity in the Indira Gandhi Medical College and Research Institute, Puducherry, India-from 2012 to 2018.
