Ozonized solutions favor the repair of experimentally induced skin wounds in rats

Effect of ozone and low power laser as therapeutic alternatives on the alveolar repair process after tooth extraction in rats wistar exposed to nicotine

PURPOSE

The aim of this study was to evaluate the alveolar repair process in rats exposed to nicotine after tooth extraction, using ozonised water and low-power laser therapy (LPLT) as therapeutic adjuvants.

MATERIALS AND METHODS

Thirty wistar rats (Rattus Norvegicus) were used and given the nicotine solution via subcutaneous tissue. After 7 days, the upper right central incisor was surgically extracted. Three days after the surgical procedure, the animals continued to receive nicotine until the day of euthanasia, totalling 21 days after extraction.

RESULTS

The result was that the groups that received coadjuvant therapy had neoformed mature bone, unlike the group that did not receive it.

CONCLUSIONS

Based on the literature and the results obtained, we can conclude that nicotine negatively influenced the healing process and bone repair in the alveoli; however, the use of ozonised water and LPLT, even in the presence of nicotine, was effective, as it enhanced the repair process, making them good options for surgical procedures in patients who smoke.

Ozonated saline intradermal injection: promising therapy for accelerated cutaneous wound healing in diabetic rats

Introduction

The use of ozonized water is gaining importance in medicine due to its effects on hyperglycemia and wound healing mechanisms.

Methods

This experiment was conducted to assess the impacts of intradermal administration of ozonated water on acute skin wound healing in a diabetic rat model. Sixty-four adult male Wistar rats were randomly divided into two groups: an ozonated water group (O3W) and a control group (CG). Experimental diabetes was chemically induced in the rats by the intraperitoneal administration of 60 mg/kg streptozotocin. One week later, full-thickness skin surgical wounds (1 cm2) were created between the two shoulders of the rats under general anesthesia. The wounds were then daily irrigated with normal saline (CG) or intradermally injected with 1 mL of ozonated water at 10 mg/L O3W. Wound healing was evaluated through macroscopic analysis, measuring wound size, diameter, and percentage of contraction rate before wounding and at 3, 7, 9, 12, 14, 18, 21, 24, and 28 days post-wounding. On days 7, 14, 21, and 28 after induction of the wounds, the body weights and blood glucose levels of rats (8 per group) were measured before the rats were euthanized. Moreover, the morphological structure of the tissue, vascular endothelial and transforming growth factor (VEGF and TGF) affinity and gene expression were examined.

Results

The O3W group had significantly lower blood glucose levels and wound size and gained body weight. Additionally, epithelial vascularization, stromal edema, TGF, and VEGF gene expression significantly improved in the O3W group.

Discussion

Therefore, ozonated water has the potential to enhance and promote cutaneous wound healing in diabetic rats.

Liquid ozone therapies for the treatment of epithelial wounds: A systematic review and meta-analysis

Ozonated water and ozonated oils are emerging as potential therapies for wound care, but their efficacy has not been appropriately evaluated. The aim of this systematic review and meta-analysis was to evaluate the therapeutic potential of topical ozone in the treatment of mammalian wounds. A structured search of five scientific databases returned a total of 390 unique studies. Of these, 22 studies were included in this review. Four studies provided enough data to be included in a meta-analysis evaluating the time to complete wound healing. All studies were randomised controlled trials of humans or other mammalian animals that reported clinical signs of wound healing. Each study was critically analysed by a six-point assessment of the risk of bias. Wounds treated with topical ozone had a greater reduction in wound size than similar wounds treated with controls or standard of care in all studies. Those treated with ozonated liquids also had a shorter time to wound healing by approximately one week. In conclusion, topical ozone contributed to enhanced wound healing in all studies. While additional human experiments would be helpful to quantify ozone's specific effects on wound healing compared to standard treatment, topical ozone should be considered as part of an overall wound management strategy.
