Brief Summary

Gaseous ozone (O3-triatomic oxygen) is the third-strongest oxidizing agent worldwide. It influences the cellular and the humoral immune system, by stimulating the proliferation of immunocompetent cells and the synthesis of immunoglobulin. Additionally; biologically active substances, such as interleukins, leukotrienes and prostaglandins which are beneficial in reducing inflammation and wound healing are orchestrated following ozone application. Given that after harvesting of a free gingival graft from the palatal donor site, healing occurs by secondary intention process; for patients with mucogingival conditions. The investigators will compare the natural process of healing at the donor site versus the healing process consecutive to ozone application; with the primary outcome is to evaluate the postoperative pain perception using visual analogue scale and to estimate the consumption of analgesics tablets after surgery.

Outcome Measures

Primary Outcomes (2)

  • Evaluation of postoperative pain using visual analog scale.

    Postoperative pain will be evaluated by visual analog scale (VAS) (Crichton, 2001). In this method, the patients will be asked to rate their pain at examination in form of a score between 0 (no pain) and 10 (the most pain which patient has ever experienced). This assessment will be made every day for the first 7 days following the FGG operation.

    7 days

  • Evaluation of postoperative pain

    The participants will report the number of analgesic tablets ingested to relieve the pain.

    7 days

Secondary Outcomes (1)

  • Evaluation of complete epithelialization of the palatal wound.

    28 days

Study Arms (2)

group 1, test group

EXPERIMENTAL

This group will receive ozone therapy after harvesting of the free gingival graft from the palatal donor site.

Device: Ozone generator device (Ozone DTA-APOZAa-enterprize CO9-Taiwan, R.0.C)

group 2, control group

NO INTERVENTION

Following harvesting of the free gingival graft, the palatal donor site ozone application will be simulated without starting of the ozone generator and the covered ( protected) by a periodontal pack.

Interventions

Gaseous ozone ( O3-triatomic oxygen) activates the neuroprotective systems, improve the blood circulation, oxygen delivery, stimulate the immunocompetent cells and enhance the release of growth factors. Moreover, ozone therapy showed to increase the quality of life post-operatively to a free gingival graft harvesting and decrease post-operative pain sensation ( Tasdemir et al, 2016)
