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