About this study

Official title: Effect of Hawthorn Vinegar, Black Mulberry Syrup and Green Tea on Quality of Life Related to Oral Mucositis and Oral Health in Individuals With Diabetes: Single Blind Randomized Controlled Study

In this context, this study investigated the quality of life related to oral mucositis and oral health in patients with DM using hawthorn vinegar, black mulberry syrup and green tea.

Read the detailed description

Diabetes Mellitus (DM) is a chronic metabolic disease that causes serious damage to the heart, blood vessels, eyes, kidneys and nerves. Both the number of cases and the prevalence of diabetes have been increased rapidly over the past 30 years. According to the report of the International Diabetes Federation (IDF) Report, approximately 537 million people worldwide (700 million in 4045) have diabetes and 6.5 million people were reported to have died due to diabetes in 2021. In Turkey, it is estimated that approximately 9 million people (about 13.5 million in 2045) are diagnosed with diabetes and approximately 80 thousand people will die from diabetes.

Prolonged hyperglycemia in DM can lead to microvascular (nephropathy, retinopathy and neuropathy) and macrovascular (peripheral vascular disease, hypertension, cerebrovascular disease, ischaemic heart disease) complications. However, due to poorly controlled DM, complications can be seen in the oral mucosa of patients with many immunological and metabolic changes. Oral complications seen in patients with DM include hyposalivation, xerostomia, bacterial, viral and fungal infections, poor wound healing, increased severity and incidence of caries, gingivitis and periodontal disease, periapical abscess, and burning mouth syndrome (BMS). These complications can lead to the development of oral mucositis in patients.

Many pharmacological and non-pharmacological agents are used in the prevention/treatment of oral mucositis. According to the classification of the National Center for Complementary and Integrative Health (NCCAM), complementary therapies methods are divided into three groups as nutritional, psychological and physiological and other complementary approaches. However, it is reported in the literature that complementary therapies such as cryotherapy (oral cooling), honey, propolis, vitamin E, selenium, aloe vera, black mulberry, apple cider vinegar, rose water and green tea are effective in the treatment of oral mucositis. Again in the literature, there are studies in which the effect of black mulberry syrup in patients with Chronic Obstructive Pulmonary Disease (COPD), apple cider vinegar and rose water mixture in cancer patients and green tea in the treatment of oral mucositis has been proven.

Oral mucositis is one of the oral diseases that can cause oral dysfunction, dysphagia and reduced oral health-related quality of life in patients. Oral and dental health affects a person's quality of life by affecting their physiological, psychological and social functioning. However, improving oral health is part of nursing care. In order to maintain a good quality of life, it is necessary to improve awareness of oral complications that occur in patients with DM. In the literature reviewed, only one experimental study was found in cancer patients in which oral mucositis-related quality of life was evaluated. There is no international or Turkish study on the treatment of oral mucositis in patients with DM. There are also no studies comparing hawthorn vinegar, black mulberry syrup and green tea in different sample groups. In this context, this study investigated the quality of life related to oral mucositis and oral health in patients with DM using hawthorn vinegar, black mulberry syrup and green tea.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Hawthorn Vinegar GroupOther

    To routine oral mucositis treatment, patients with DM in the hawthorn vinegar group gargled with 1 tablespoon (10 cc) of diluted hawthorn vinegar (mixed with 40 cc water) for 1 minute 15-20 minutes before meals 3 times a day for 14 days.

  • Black Mulberry Syrup GroupOther

    To routine oral mucositis treatment, patients with DM in the black mulberry syrup group pure black mulberry syrup for 1 minute 15-20 minutes before meals 3 times a day for 14 days.

  • Green Tea GroupOther

    To routine oral mucositis treatment, patients with DM in the green tea group gargled with 50 cc green tea for 1 minute 15-20 minutes before meals 3 times a day for 14 days.

Study groupRoleWhat they receive
Hawthorn Vinegar GroupExperimentalBefore starting the study (pre-test/0. week), "Patient Information Form", "OAG" and "OHQoL-UK" were administered to all group participants to evaluate the level of oral mucositis in patients. In addition to routine oral mucositis treatment, patients with DM in the hawthorn vinegar group gargled with 1 tablespoon (10 cc) of diluted hawthorn vinegar (mixed with 40 cc water) for 1 minute 15-20 minutes before meals 3 times a day for 14 days. "OAG" and "OHQoL-UK" were administered again on the 7th day (interim-measurement) and 14th day/end of the study (post-test).
Receives: Other: Hawthorn Vinegar Group
Black Mulberry Syrup GroupExperimentalBefore starting the study (pre-test/0. week), "Patient Information Form", "OAG" and "OHQoL-UK" were administered to all group participants to evaluate the level of oral mucositis in patients. In addition to routine oral mucositis treatment, patients with DM in the black mulberry syrup group gargled with 1 tablespoon (10 cc) of pure black mulberry syrup for 1 minute 15-20 minutes before meals 3 times a day for 14 days. "OAG" and "OHQoL-UK" were administered again on the 7th day (interim-measurement) and 14th day/end of the study (post-test).

Green Tea GroupExperimentalBefore starting the study (pre-test/0. week), "Patient Information Form", "OAG" and "OHQoL-UK" were administered to all group participants to evaluate the level of oral mucositis in patients. In addition to routine oral mucositis treatment, patients with DM in the green tea group gargled with 50 cc green tea for 1 minute 15-20 minutes before meals 3 times a day for 14 days. "OAG" and "OHQoL-UK" were administered again on the 7th day (interim-measurement) and 14th day/end of the study (post-test).
Receives: Other: Green Tea Group
Control GroupNo interventionPatients in the control group received no any treatment other than routine oral mucositis treatment and data collection tools. "Patient Information Form", "OAG" and "OHQoL-UK" were administered to the patients before the study (pre-test/0th week) and "OAG" and "OHQoL-UK" were administered again on the 7th day (mid-measurement) and 14th day/end of the study (post-test).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Oral Assessment Guide (OAG)

    The "OAG" is useful for assessing and recording the individual's daily oral condition, as well as detecting the presence of mucositis and evaluating the effectiveness of treatment. The "OAG" consists of 8 categories including voice, dysphagia, lips, tongue, saliva, mucous membranes, gums and teeth/prostheses.

    "OAG" was administered again on the 7th day (interim-measurement) and 14th day/end of the study (post-test).

    Measured: 14 Days

  2. Oral Health Related Quality of Life Scale (OHQoL-UK)

    The 5-point Likert-type scale, which consists of a total of 16 items to determine the degree of impact of teeth, gums, mouth or prosthesis, consists of 4 dimensions: "symptom" (items 1-2), "physical condition" (items 3-7), "psychological condition" (items 8-12) and "social condition" (items 13-16). Each item in the scale is scored as "Very bad effect-1, bad effect-2, no effect-3, good effect-4, very good effect-5". The total score of the scale varies between 16-80, and a high score indicates a high level of oral and dental health-related quality of life. The Cronbach alpha value of the scale was reported as 0.94.

    "OHQoL-UK" was administered again on the 7th day (interim-measurement) and 14th day/end of the study (post-test).

    Measured: 14 Days

Model description
The sample size of the study was calculated as 128 individuals in total (32 for each group) for 4 groups (hawthorn vinegar, black mulberry syrup, green tea, control group) with an effect size of 0.25 with α=0.05 and the power of the targeted test was 0.80 (80%) in the G\*Power 3.1.9.7 program, which could not be used as a reference since there was no previous four-group study on the subject. Each group was increased to account for drop-outs and deaths and a total of 140 individuals, 35 for each group, were included in the study
