Periodontal Dressing After Surgical Crown Lengthening

Phase 2

Completed

• Conditions: Pain; Periodontal Infection; Wound Healing Disturbance of
• Interventions: Procedure: With Periodontal dressing; Procedure: Without Periodontal dressing

• Registration Number: NCT01986959
• Lead Sponsor: Franciscan University Center

Brief Summary

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.

Arm && Interventions

Group	Intervention	Description
Surgery with Periodontal dressing	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).
Surgery without Periodontal dressing	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).

Primary Outcome Measures

Name	Time	Method
Position of the gingival margin	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.

Secondary Outcome Measures

Name	Time	Method
Healing	Seven Days	The healing of the surgical wound was evaluated based on the type of migration of the free edges of epithelium. Healing by first intention was determined by the migration of the epithelium toward the bed of the wound. Cases in which an area of conjunctive tissue and/or bone was uncovered by epithelium and re-epithelialization by the adjacent epithelium was occurring were classified as healing by second intention
Local infection	seven Days	Infection was defined as present if the patient has at the surgical site, postoperative pain around the site, which increased in intensity at any time between 1 and 3 days after the procedure, with or without the presence of halitosis.
Pain and discomfort	Seven days	A questionnaire for the evaluation of pain and sensitivity on the first, second, third and seventh days postoperatively was given to each patient to fill out at home. All evaluations involved a record of the number of analgesics taken as well as a visual analog scale (VAS, ranging from 0 \[absence of pain\] to 100 \[unbearable pain\] mm) and a verbal scale (VS) with the following responses: no pain; mild pain; moderate pain; severe pain; and very severe pain. The patients were instructed to fill out the scales between 8 and 9 pm every day. Following removal of the dressing, in seven days, the examiner administered the pain scales (VAS and VS).
Gingival bleeding	Seven days	Following removal of the dressing, the examiner determined the presence of gingival bleeding as present or absent (Ainamo and Bay, 1975.
