Postsurgical care

All patients were instructed to avoid trauma and to discontinue tooth brushing at the surgical site during a 7-day period. Participants were instructed to rinse with a 0.2% chlorhexidine digluconate solution for 1 min, twice a day for 15 days, and a nonsteroidal anti-inflammatory agent was prescribed for pain control and antibiotics were prescribed for 3 days. After 7 days, sutures and coe pack was removed. Participants were recalled at 24 h after the surgery, and after 7 and 14 days for postoperative angiography. In the same session, photographs were taken of the treated areas with a digital camera (Nikon Cool Pix S9100).
