Decision-making in aesthetics: root coverage revisited.

Over the years, numerous surgical techniques have been introduced to correct labial, gingival recession defects. Aesthetic concerns are usually the reason to perform these procedures. Clinical studies have evaluated many of the techniques. The depths of the defects have been measured before surgery and at a follow-up examination after 6 months or later. Results in terms of mid-surface root coverage have been expressed in millimeters and as the percentage of original defect that has been covered. Also, percentage defects with complete coverage have often been reported. The results of available studies have been evaluated (30, 117, 119). Mean root coverage for the treated patient groups ranges from around 50% to close to 100% of the original defect depth. Mean root coverages of 70–80% seem most common. Complete root coverages have been achieved in about 50% of the treated defects. These results were confirmed by our own updated review and compilation of data
