Whale tail technique a type of papilla preservation surgery is used in wide interdental spaces involving semilunar incisions. Since it involves wider surgical zone, its healing pattern needs to be assessed. Hence for post-surgical wound monitoring two healing indices were analysed. Early healing changes were assessed by new index Early wound healing score (EHS) for monitoring the periodontal soft tissues 24 hours after surgical incision. Following this, healing changes at different time intervals were assessed by Landry healing index to derive the clinical patterns of healing in wide semilunar incisions. 20 patients indicated for whale’s tail technique were included in the study, the postoperative monitoring done were at 24 hours to assess EHS to observe the re-epithelization, hemostasis and inflammation. Landry index was assessed at different time intervals at 1 week, 2 weeks and 1 month to derive the tissue changes in terms of color, incision margin, bleeding, and contours. With these indices, the clinical patterns of healing were documented in wide surgical areas.
