Abstract

Abstract: Objective: To estimate the effectiveness of concentrate growth factors (CGF) combined with connective tissue graft (CTG) and coronally advanced flap (CAF) for the treatment of Miller Class Ⅰ gingival recession (GR). Methods: Thirty GR patients with Miller Class Ⅰ (42 sites) were selected and randomly divided into experimental group (CAF+CTG+CGF) and control group (CAF+CTG), with 15 cases in each group. The postoperative effects of the two groups were compared. Results: Six months after operation, the decrease of gingival recession height and width, the increase of keratinized tissue width, and the score of numerical rating scale (used to estimate postoperative pain and swelling) at 24 h, 2 d, and 7 d after surgery were statistically significant (P<0.05). However, there was no significant difference in the complete root coverage between experimental group (90.90%) and control group (65.00%, P>0.05). Conclusion: CGF, as an auxiliary material for CAF+CTG, can reduce the height and width of gingival recession 6 months after surgery, increase the keratinized tissue width, and ameliorate the pain and swelling at 24 h, 2 d, and 7 d after surgery, which opens up a new idea for the treatment of GR.
