Defects of the labial gingiva in the area of the lower central incisors often uni, bi, -lateral present a difficult problem. An attempt was made to correct the defect by a sliding flap operation.
Incisions are made on each side of the defect, removing the inflamed margins and extending straight below the base of the defect. Complete removal of the epithelial lining of the soft tissue and the epithelium attachment. Another incision is made at the distance of one papilla distal to the defect, straight down into the mucosa. The flap is full thickness though the keratinized and split through the mucosa. After the flap is movable , a sutured to place. The area is packed. IM Bicillin was given to prevent secondary infection and maintain the blood clot. Post-op- liquid diet for 3 days. The wound is uncovered after three days to remove the sutures. Area is cleansed. All edges of the wound surface are cauterized with 30% trichloroacetic acid and immediately rinsed with warm water. A pack is placed and left for 12-16 days. In 21 to 30 days the denuded area is completely healed.
Importance is the blood supply of the flap to be used. A sliding flap operation was used to cover up exposed root surfaces. This operation is often combined with frenotomy. The time of post-op of the cases presented was rather short and prevent final judgment of possible re-attachment.
