Wound Healing After Gingivectomy

Gingival enlargement caused by chronic inflammation may require surgical intervention when non-surgical periodontal therapy is insufficient. Gingivectomy and gingivoplasty are commonly performed procedures to remove excessive gingival tissue and restore normal gingival contour. However, postoperative wound healing may be affected by factors such as microbial contamination and the inflammatory response. Medical ozone therapy has antimicrobial, anti-inflammatory, and biostimulatory properties that may enhance tissue regeneration and accelerate wound healing. The aim of this randomized split-mouth clinical trial is to evaluate the effect of adjunctive gaseous ozone therapy on wound healing following gingivectomy/gingivoplasty in individuals with chronic inflammatory gingival enlargement. Twenty-four systemically healthy participants diagnosed with chronic inflammatory gingival enlargement will be included. Surgical sites will be randomly assigned in a split-mouth design to either the test group (gingivectomy/gingivoplasty with adjunctive gaseous ozone application) or the control group (gingivectomy/gingivoplasty alone). Clinical periodontal parameters (Plaque Index, Gingival Index, Bleeding on Probing, Probing Pocket Depth, and Clinical Attachment Level) will be assessed at baseline and post-operative Day 21. Histopathological outcomes (Superficial Cell Index and Keratinization Index) will be evaluated at baseline and on post-operative Days 1, 3, 7, and 21. The results of this study are expected to provide clinical and histopathological evidence regarding the potential benefits of adjunctive ozone therapy in periodontal wound healing.

Comparative Evaluation of Hyaluronic Acid Spray and Low-Level Laser Therapy on Wound Healing Following Gingivectomy

Gingival enlargement may impair oral hygiene, esthetics, and periodontal health, and gingivectomy is commonly performed when non-surgical treatment is insufficient. Because gingivectomy wounds heal by secondary intention, postoperative wound healing and pain control are clinically important. Low-level laser therapy and hyaluronic acid are adjunctive approaches that may support tissue healing through different biological mechanisms. This randomized controlled clinical trial compared the effects of topical 0.04% high-molecular-weight hyaluronic acid spray and low-level laser therapy on early wound healing and postoperative pain following gingivectomy. Sixty-four systemically healthy patients requiring gingivectomy were randomly assigned to receive either hyaluronic acid spray applied twice daily for 7 days or 940-nm diode laser therapy applied on postoperative days 0, 3, 5, and 7. Wound healing was assessed using standardized clinical photographs and digital planimetric analysis at baseline and on postoperative days 3, 7, and 14. Postoperative pain was evaluated using a visual analogue scale, and periodontal parameters were recorded at baseline and 6 weeks. The study aimed to compare these two adjunctive postoperative wound-management approaches after gingivectomy.

Comparison of the Effect of Ozonized Gel to That of Photobiomodulation Therapy on Wound Healing Following Surgical Gingivectomy

The goal of this clinical trial is to compare the effect of photobiomodulation to ozonized gel on wound healing following gingivectomy procedure on adults. The main questions it aims to answer are: Which treatment modality provides less painful and more efficient wound healing ? What are the patient's feedback on different treatment modalities ? Researchers will compare ozonized gel to photobiomodulation to normal gingivectomy procedure with no interference. Participants will: Receive either ozonized gel or photobiomodualtion treatment following surgical gingivectomy Visit the clinic every 3,7,14 and 28 days for checkups and investigations

Lymphocyte Subpopulations in Peripheral Giant Cell Granuloma

Peripheral giant cell granuloma (PGCG) is a non-neoplastic inflammatory lesion of gingival tissues. This study aims to evaluate and compare lymphocyte subpopulations in PGCG tissues and adjacent healthy gingival tissues obtained from the same individuals. A total of 28 systemically healthy, non-smoking patients diagnosed with PGCG are included in this study. Biopsy samples are collected during surgical excision of PGCG lesions, and corresponding healthy gingival tissues are obtained from the same patients. Immunohistochemical analysis is performed to assess lymphocyte subpopulations, including CD3, CD4, CD8, CD20, and CD79a. The proportions of these cells are compared between diseased and healthy tissues.

Testing the Efficacy of Photobiomodulation Therapy and Hyaluronic Acid Gel on Post-surgical Healing After Gingivectomy

This study consists of random patient selection and allocating them in 3 different groups. After being fit to be included according to the protocol's criteria and signing an informed consent, patients will be distributed after performing a dental surgery known as gingivectomy. Gingivectomy has been classified as the gold standard treatment option for the control of gingival enlargement. Wound recovery after gingivectomy and gingivoplasty occurs by secondary intention healing, thus post-surgical wounds can be strongly associated with discomfort, pain and delayed healing. For that reason, the first group will consist of 13 patients who will be exposed to hyaluronic acid gel or gingigel and photobiomodulation therapy to see if there is significant results in the post-operative healing phase. The second group will also consist of 13 patients who will undergo only photobiomodulation therapy. While the third group will have no clinical supportive care besides follow-up and analgesics upon request. All the values will be determined by using scores such as Visual analogue scale for pain, Landry's index for healing assessment and oral health quality of life, which consists of 14 questions to asses the enhancement of everyday problems affected by dental situations. Each case will be followed-up for 3 months post-operative.

The Effect of Ozone Therapy on Gingivoplasty

Ozone therapy after gingivectomy and gingivoplasty has been found to reduce patients' pain levels and positively impact their quality of life. This study aimed to compare the healing potential of the wound surface following gingivectomy and gingivoplasty surgery applied to the maxillary anterior regions with classical periodontal paste application (Coe-pak) using activated oxygen (Cure 09 Active Oxygen) and classical periodontal paste application only (Coe-pak). The study will include 48 systemically healthy patients older than 18 years of age with gingival enlargement in the maxillary anterior region, requiring gingivectomy and gingivoplasty surgery, who applied to Kütahya University of Health Sciences, Faculty of Dentistry, Department of Periodontology and Izmir Democracy University, Faculty of Dentistry, Department of Periodontology. Patients will be evaluated in two different groups as test and control group after surgery. Patients will be randomly divided into study groups by closed envelope method. The test group will receive periodontal paste (Coe-pak) + Ozone therapy (active oxygen (Cure 09 Active Oxygen)) after gingivectomy and gingivoplasty surgery, while the control group will receive only periodontal paste after gingivectomy and gingivoplasty surgery. All patients will undergo gingivectomy and gingivoplasty with the same procedure
