Comparison of the Effectiveness of Three Different Gargates in Radiotherapy-Associated Oral Mucositis

Study Overview
=================
Brief Summary
-----------------
This study was conducted to compare the effectiveness of thyme honey, saline and sodium bicarbonate solution in the management of oral mucositis in patients with head and neck cancer receiving radiotherapy.

Detailed Description
-----------------
The research was conducted as a randomized controlled clinical trial between January 2020 and January 2022. The sample of the research; Patients who applied to Hospital Radiotherapy Unit, received 50-60 Gy radiotherapy in the oral cavity, had a primary diagnosis of head and neck cancer, had no metastasis, had no complaints about mucositis, were older than 18 years old, spoke Turkish, and agreed to participate, in the study. With the closed-envelope randomization method, 48 patients were included in the sample, 12 patients for each of the saline, sodium bicarbonate, thyme honey, and control groups. The routine protocol of the clinic was applied to the control group. Patients in the intervention group (thyme honey, saline and sodium bicarbonate group) were treated 3 times a day for 6 weeks, in addition to the routine protocol of the clinic; they were asked to gargle with 20 ml of the solution in the group they were randomized to, 15 minutes before, 15 minutes and 6 hours after radiotherapy. Intraoral evaluations were made every week by the responsible physician of the radiotherapy unit, who did not know which group the patients were in (single blind). Study data; Obtained using the Sociodemographic and Disease Data Collection Form, the National Cancer Institute Common Toxicity Criteria v4.03, the Oral Evaluation Guide, and the Washington University Quality of Life Questionnaire. In the study, Chi-square analysis was used for the relationship between two categorical variables, One-way Anova for differences in measurements, Levene test for homogeneity of variance, and Bonferroni analysis to find out from which group or groups the difference originated. Support was received from the Health Sciences University Scientific Research Project Office for the study (2020/029)

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Saline<br>The patients in the group gargling with saline were given in a 500 ml bottle at each visit for one week of use. Patients were told that they should gargle using approximately two tablespoons of the solution given for each usage. | Other: Salin<br>* Patients were told that they should gargle using approximately 2 tablespoons of the solution given for each use. SF solution was obtained from the medical company as 500 ml separately for each patient.<br>|
| Experimental: Sodium Bicarbonate<br>The sodium bicarbonate solution prepared by the researcher by mixing one teaspoon of baking soda (4.5 grams) into 500 ml of distilled water by the researcher was given to the patients in the group gargling with sodium bicarbonate for a one-week use at each interview. Patients were told that they should gargle using approximately two tablespoons of the solution given for each usage. | Other: Sodium bicarbonate<br>* Patients were told that they should gargle using approximately two tablespoons of the solution given for each use. The 500 ml distilled water bottle to be used for the SB solution was obtained from the medical company, separately for each patient.<br>|
| Experimental: Thyme Honey<br>20 ml of honey was diluted in 100 ml distilled water bottles by the researcher to the patients in the group gargling with thyme honey. For a week's use, the patient was given five honey solutions in 100 ml bottles at one time at each visit. Patients were told that they should gargle using approximately two tablespoons of the solution given for each use. | Other: Thyme honey<br>* Patients were told that they should gargle using approximately 2 tablespoons of the solution given for each use.<br>|
| Experimental: Control<br>No solution was given to the patients in the control group by the researcher. | Other: Control<br>* The patients continued to use the antifungal solution containing the active ingredient nystatin, which was prescribed routinely in the clinical procedure, 3 times a day.<br>|
