简要总结
Background: There is controversy regarding the postoperative effects of periodontal dressing on the periodontium, pain and discomfort. The aim of the present study was to compare postoperative pain following surgical crown lengthening with and without the use of periodontal dressing.
Material and Methods: A blind, randomized, clinical trial was carried out with 36 patients. Following surgical crown lengthening, the individuals were randomly allocated to the periodontal dressing group (PDG) and control group (CG - non-placement of periodontal dressing). Pain and discomfort were analyzed using a visual analog scale (VAS), verbal scale (VS) and the number of analgesics consumed in seven days postoperatively. Postoperative infection, stability of the gingival margin and type of healing were also evaluated.

研究组 & 干预措施
Surgery without Periodontal dressing
After surgery, the patients were randomly allocated to the periodontal dressing group (PDG) and control group (CG - non-placement of periodontal dressing).
干预措施: Without Periodontal dressing (Procedure)
Surgery with Periodontal dressing
After the Surgical crown lengthening, the patients were randomly allocated to the periodontal dressing group (PDG) and control group (CG - non-placement of periodontal dressing).
干预措施: With Periodontal dressing (Procedure)
结局指标
主要结局
Position of the gingival margin
时间窗: Seven days
Following removal of the dressing, the examiner determined the position of the gingival margin. This position was determined individually using the same procedure performed in the immediate postoperative period based on the previously recorded fixed reference points. The determination of gingival recession, position of the gingival margin and gingival swelling was performed categorically, using the gingival margin in the immediate postoperative period for comparison.
次要结局

- Local infection(seven Days)
- Pain and discomfort(Seven days)
- Gingival bleeding(Seven days)
