Abstract
Background: Oral mucositis and local pain are the negative effects of the treatment of head and neck cancer with radiotherapy. Objectives: The study aimed to investigate the effect of ozonated water on the severity of mucositis and pain in (1) patients who were treated with ozonated water and (2) patients who were not treated with ozonated water. Methods: We randomly divided 93 patients with head and neck malignancy (aged 18 to 80) into three groups. Ozone-treated group 1 rinsed their mouth with 15 mL of ozonated water with a concentration of 20 - 50 ppm from the first session of radiotherapy for one minute before and after each session. Ozone-treated group 2 rinsed their mouth with 15 mL of ozonated water with a concentration of 20 - 50 ppm for three minutes and then swallowed it before and after each session. Ozone-treated groups 1 and 2 and the non-ozone-treated group received standard treatment if mucositis symptoms appeared in each patient. The minimum number of radiotherapy sessions was 30, and the minimum planned dose for each patient was 50 Gray. Anamnesis and the following clinical parameters were taken: the degree of mucositis, the use of corticosteroids, radiotherapy method, radiation dose, and Pain Visual Analog Scale. Multi-level and subgroup analyses were performed on the ozone-treated and non-ozone-treated levels. Results: The mean degrees of oral mucositis and pain were lower in the ozone-treated group 2 than in the ozone-treated group 1 and non-ozone-treated group (P < 0.05). The non-ozone-treated group had the highest degrees of oral mucositis and pain severity (P < 0.05). The Kruskal-Wallis H test showed that there was a statistically significant difference in the Visual Analog Scale of sessions 5, 10, 15, 20, 25, and 30 between different groups. However, there was no statistically significant difference in the Visual Analog Scale of session 1 (χ2 (2) = 1.022, P = 0.6). This study revealed that ozonated water can be used for preemptive pain control and mucositis. This finding aligned with previous studies. Also, former research proved the safety and efficacy of ozonated water in dentistry and medical uses. Conclusions: The use of ozonated water in patients with head and neck malignancy can reduce the pain severity and oral mucositis induced by radiotherapy. It seems that ozonated water can be used as a preemptive agent in patients who receive head and neck radiotherapy.
