Primary outcomes: Width and thickness of keratinized tissue
tooth
CAVITY, PERIOSTEUM
The patient's oral cavity was examined by a specialist with Williams Probe (Hu‐Friedy; Chicago, USA) to evaluate the clinical parameters. The evaluated parameters such as probing pocket depth (PPD), keratinized tissue width, VD, and gingival thickness (GT) were measured at the baseline, and after 8 weeks. GT measurements were taken using an endodontic spreader (#30) from 2 mm of the buccal gingival margin as shown in Figure (a) Preoperative view. The first premolars with an attached gingiva width less than 2 mm. (b) A horizontal incision half a millimeter above the mucogingival junction line, with one‐and‐a‐half tooth extension. (c) Absorbable suture is used to secure the flap in the apical position. (d) Placement of periodontal dressing to protect the wound. (e) Eight weeks postop.(a) Preoperative view.
