Coronally repositioned periodontal flap. Clinical evaluation after one year

After increasing the width of the attached gingiva by free palatal mucosa transplants, 20 procedures with coronal flap repositioning were performed on 41 teeth with gingival recessions in 13 young adults. The amount of gingival recession and the clinical gingival sulcus depth were measured pre-operatively and 1, 6 and 12 months after surgery; the amount of osseous dehiscence was measured during surgery. No significant differences were found among reduction values of gingival recession by reattachment 1, 6 and 12 months post-operatively. Although a significant correlation was found between the degree of gingival recession preoperatively and 1 month post-operatively, non was found between the amount of alveolar bone dehiscence and gingival recession 1 month post-operatively.
