Evaluation of root coverage with two connective tissue grafts obtained from the same location.

The purpose of this study was to compare the clinical root coverage achieved with two connective tissue grafts that were removed from the same donor area at different times and used in subepithelial grafts for root coverage. Sixty patients, each of whom had two connective tissue grafts removed from the same donor area at different times, were included in this study. The connective tissue grafts were used in two different subepithelial grafts for root coverage.

Clinical evaluation of a combined regenerative technique with enamel matrix derivative, bone grafts, and guided tissue regeneration.

The goal of this study was to evaluate the clinical changes obtained when intra-bony defects were treated with an enamel matrix derivative (EMD), a bone graft, and guided tissue regeneration. Fifty patients with a periodontal defect not associated with a furcation and with an attachment loss of at least 7.0 mm were included in this study.
