Clinical Evaluation Of Ozone Gel Versus Hyaluronic Acid Gel On Palatal Wound Following Free Gingival Graft Harvesting: A Randomized Clinical Trial, Hisham Tarek, Nesma Shemais, Dalia Ghalwash, • Ahmed El Barbary

Dentistry

Objective: This randomized clinical trial (RCT) compares the effectiveness of ozone gel (GeliO3) and hyaluronic acid (HA) gel(Gengigel) in enhancing wound healing and reducing postoperative discomfort following free gingival graft (FGG) harvesting.Methods: Fifty-six patients requiring FGG for mucogingival defects were randomly assigned into two groups: the ozone gel group and the HA gel group. The primary outcome was postoperative pain, assessed using the visual analog scale (VAS) and analgesic consumption. Secondary outcomes included wound healing, evaluated using the Landry healing index, and color match assess-ment. Data were analyzed using appropriate statistical tests with a significance level of p< 0:05.Results: Both treatment groups exhibited significant pain reduction over time (p< 0:001). Although there was no statistically significant difference between the groups, a faster decline in pain was observed in the ozone group by Day 3. Analgesic consumption was significantly lower in the ozone group on Days 2 and 3 (p ¼ 0:042). The healing index and color match scores showed a steady improvement in both groups, with the ozone group demonstrating slightly higher values at various time points, though not statistically significant.Conclusion: Both ozone gel and HA gel effectively enhanced post-FGG healing, reduced pain, and improved tissue esthetics.Ozone therapy showed potential advantages in early pain relief and lower analgesic dependence. These findings suggest that ozonetherapy may serve as an alternative or adjunctive treatment for palatal wound management in periodontal surgery. Furtherresearch is needed to confirm its clinical superiority over HA gel.

The Role Of Inflammatory Cytokines In The Bidirectional Relationship Between Periodontitis And Diabetes Mellitus, Andrew R. Witty

Oral Health

Periodontitis and type 2 diabetes mellitus are associated with each other in a bidirectional relationship. The mechanism by which diabetes affects periodontitis is understood to be due to the inflammatory effects of hyperglycemia (high blood glucose levels) and a hospitable environment for sugar-consuming bacteria. Periodontitis is known to be associated with higher levels of glycated hemoglobin (HbA_1c), a long-term measurement of blood glucose control, and treatment of periodontitis reduces HbA_1c. Inflammation caused by periodontitis induces insulin resistance (which leads to higher blood glucose levels), but due to the complex nature of inflammation it is difficult to …
