Summary

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.

Detailed description

The study group consisted of thirty-nine surgical gingivectomy wound sites on patients presenting with gingival hypertrophy on maxillary or mandibular anterior region. Groups will be randomly and equally divided into three groups, Group-A (Test Group 1): Surgical sites after gingivectomy procedures will be irradiated with diode laser (Photobiomodulation therapy) at (940 nm, 0.21 W) with a fiber tip diameter of 400μm for 30 seconds, then covered with HA Gel. Group-B (Test Group 2): Surgical sites will be irradiated with diode laser only at (940 nm, 0.21 W). Group-C (Control Group): No post-surgical therapy will be performed. Wound healing was assessed by implementing Landry, Turnbull and Howley Healing index, while pain perception was objectively evaluated by the patients using the visual analog scale (VAS). To further evaluate the patient's quality of life, Oral Health Impact Profile (OHIP-14) records will be obtained before and after gingivectomy.

Conditions

• Gingival Hyperplasia
• Gingival Hypertrophy
• Gingival Overgrowth
• Gingival Enlargement
• Photobiomodulation Therapy
• Low-level-laser Theraphy

Interventions

Type	Name	Description
DRUG	Gengigel	The use of Gingigel or 0.2% hyaluronic gel is expected to enhance healing and decrease discomfort in the post-operative period. It exhibits viscoelastic characteristic which serves as osteo-conductive, anti-edematous, antifungal and bacteriostatic effects.
DEVICE	LASER	PBMT has markedly been effective in reducing pain, inflammation, edema and postoperative discomfort. It is said to be a natural and effective alternative approach to minimize medicaments prescription such as analgesics, anti-inflammatory or antibiotic drugs. With that said, negative outcomes such as drug side effects, bacterial resistance and post-operative complications can be prevented, thus increasing the success of medical care and assuring a better quality of life
