Acute or chronic inflammatory reactions aim to control lesions, resist to pathogens attack and repair damaged tissue. The therapeutic administration of ozone known as ozone therapy appears as a possible treatment for tissue repair, as it promotes the healing of wounds. It has bactericidal, antiviral and antifungal properties and has been used as a therapeutic resource to treat inflammation. The objective was to carry out an integrative review regarding the use of ozonated oil in acute and chronic inflammations. The keywords “ozone therapy,” “inflammation” and “ozone” were used in the Portuguese, Spanish and English languages. The paper selection was based on inclusion and exclusion criteria. In total, 28 articles were selected. It has been seen that ozonated oil is effective in healing cutaneous wounds. The beneficial effects are due to the healing of wounds, due to the reduction of microbial infection, debridement effect, modulation of the inflammatory phase, stimulation to angiogenesis as well as biological and enzymatic reactions that favor the oxygen metabolism, improving the wound cicatrization. In addition to promoting healing, ozonated oil reduces symptoms related to skin burns, prevents post-lesion hyperpigmentation, and reduces the pain of aphthous ulcers. Therefore, ozonated oil represents an effective and inexpensive therapeutic alternative that must be implanted in the public health system.

BACKGROUND AND OBJECTIVES: Osteoarthrosis affects 85% of the population over 75 years of age. It is divided into primary and secondary, however despite the knowledge at the molecular level the treatments are not yet fully effective. However, ozone therapy emerges as an alternative therapy, which is low cost and seems effective in the treatment of chronic pain. The objective of this study was to evaluate the current evidence to support or to refute the use of ozone therapy in the treatment of patients with osteoarthritis. CONTENTS: Systematic review using the keywords "ozone therapy", "ozone", "osteoarthritis", "arthritis", "randomized", "controlled" and "meta-analysis". The selection of publications was based on inclusion and exclusion criteria. In total, 9 articles were used. Among the 9 articles found regarding ozone therapy in osteoarthritis, 7 of them clearly show the benefits of ozone. The concentrations of ozone used in the studies ranged from 20μg/mL to 15g/mL. The route of administration was intra-articular and rectal insufflation. The frequency of use was, on average, 1 to 3 times a week and the treatment time was between 3 to 4 months in most of the studies. CONCLUSION: The use of ozone produces clinically relevant benefits in patients with osteoarthrosis. Therefore, ozone therapy in osteoarthrosis represents a low-cost, efficient therapeutic alternative that should be implemented in the country's Public Health, considering the prevalence of the disease.
