(a) Root planing using sharp Gracey curette. (b) Root detoxification using EDTA gel for 2 minutes. (c) Using 15C blade to make partial thickness flap. (d) The coronally repositioned semilunar flap was secured by three horizontal mattress sutures and fixed with flowable composite to the crown of the tooth.

The exposed root was properly instrumented with a Gracey 3/4 curette and frequently irrigated with normal saline (Figure 3(a)). The root was then conditioned with EDTA gel for 2 minutes, followed by profound irrigation (Figure 3(b)). The apical margin of the partial thickness flap was excised to make a semicircular flap (Figure 3(c)). The sutures were held by flowable composite on dry, etched, and bonded enamel (Figure 3(d)).
(a) Ten days after removing the periodontal dressing and sutures. (b) Two months later, the gingiva was very stable and showed resistance to the periodontal probe. (c) At six months, the gingiva remained very stable with small amount of scar tissue on the donor area and was filled with composite filling. (d) 32 months postoperatively, the gingiva looked very stable and healthy.

After 10 days, the periodontal dress and sutures were removed, and the recession was fully covered (Figure 4(a)). No surgical recession was observed after 10-day, 20-day, one-month, and two-month follow-ups (Figure 4(b)). The tissue was firmly attached to the root surface with 1 mm sulcular depth at two-month and 6-month follow-up time (Figure 4(c)). Sixteen months later, the gingiva and the restoration looked very stable (Figure 4(d)).
