Study Overview
Brief Summary
The aim of the study is to evaluate the effects of using droplet-form platelet-rich plasma (PRP), known to have positive effects during the intermediate healing process, on wound healing in areas left for secondary healing after gingivectomy.
After the gingivectomy procedure, patients will be divided into four groups, each consisting of 10 individuals:
Group 1 (Control Group): This group will follow the standard post-gingivectomy protocol without any agent applied to the surgical site.
Group 2 (Placebo Group): In this group, the standard protocol will be followed, and physiological saline will be applied to the surgical site in 3-4 drops, four times a day, for 14 days.
Groups 3 and 4 (Study Groups): These groups will follow the standard protocol, with PRP prepared using different kits applied to the surgical site in 3-4 drops, four times a day, for 14 days.
All patients in the groups will be evaluated on the 3rd, 7th, 14th, and 30th days after the gingivectomy procedure. Postoperative pain will be assessed using the Visual Analog Scale (VAS), while wound healing will be evaluated using the Healing Index (Landry et al.) based on photographs of the region. Before taking standardized photographs, the surgical area will be stained with two-tone dye.
Detailed Description
The aim of this study is to evaluate the effectiveness of platelet-rich plasma (PRP) prepared with different kits in improving the healing rate and enhancing patient comfort during the recovery process in the secondary healing areas following gingivectomy.
Systemically healthy individuals, patients with inflammatory gingival overgrowth, patients without periodontal treatment in the operative area within the last year, non-smokers and patients with intact periodontal structures will be included to the study. Also pregnant or breastfeeding patients, Patients below 18 or above 55 ages, smoking patients, patients with systemic diseases and who received periodontal treatment in the operative area within the last year and who use of medications causing gingival overgrowth will be excluded from the study.
Methodology:
A total of 40 patients meeting the inclusion criteria and willing to participate in the study will be recruited from those attending the Periodontology Clinic at Erciyes University Faculty of Dentistry for gum disease treatment.

Arms & Interventions
Group 1 (Control group)
Standard post-gingivectomy protocol without any agent applied to the surgical site
Group 2 (Placebo)
Standard protocol with 3-4 drops of physiological saline applied to the surgical site, four times a day, for 14 days.
Intervention: Placebo (Other)
Group 4 (PRP Kit 2)
Standard protocol with PRP prepared using Kit 2, applied to the surgical site in the same manner as the placebo group.
Intervention: PRP (Other)
Group 3 (PRP Kit 1)

Intervention: PRP (Other)
Outcomes
Primary Outcomes
The amount of wound healing
Time Frame: On the 3rd, 7th, 14th, and 30th days following the gingivectomy procedure
The wound area was stained with two-tone dye, and standardized photographs will be taken. Wound healing then was evaluated using the Healing Index (Landry et al.) based on the photographs. The Healing Index is designed on a 1-5 scale, where 1 indicates very poor healing, and 5 indicates excellent healing.
Secondary Outcomes
- Periodontal changes(Before the initial periodontal treatment and at the first month after gingivectomy)
- postoperative pain(On the 3rd, 7th, 14th, and 30th days following the gingivectomy procedure)
