<qa>  What was the surgical bade on the buccal aspect of the involved tooth?III. Under local anesthesia, an intrasulcular incision was given using a surgical bade on the buccal aspect of the involved tooth. The incision was extended horizontally to dissect the buccal aspect of the adjacent papillae, both mesially and distally, leaving the gingival margin of the adjacent teeth untouched. Two oblique releasing incisions were made from the mesial and distal extremities of the horizontal incision beyond the mucogingival junction.
