Evaluation of the efficacy of 100% Type-I collagen membrane of bovine origin in the treatment of human gingival recession: A clinical study

BACKGROUND: Various treatment modalities have been devised for gingival recession, which is one of the most common signs of periodontal disease. The present study evaluates the efficacy of bioresorbable 100% type I collagen membrane of bovine origin in the treatment of human gingival recession. MATERIALS AND METHODS: Twenty cases of Miller's class I or class II localized gingival recession defects on the facial surface were treated with 100% type I collagen membrane of bovine origin in conjunction with coronally positioned flap. Pre-operative and post-operative assessments were performed with respect to probing pocket depth, clinical attachment level and clinical recession at 12, 24 and 36 weeks. The data thus collected were analyzed statistically. RESULTS: Statistically significant improvement based on Student's t test was found in all the three clinical parameters. CONCLUSION: Bioresorbable 100% type I collagen membrane of bovine origin has given inspiring results in the treatment of human gingival recession defects, thereby justifying the use of this material wherever indicated.
