Brief summary

Sjögren's syndrome (SS) is a chronic, systemic and autoimmune disease characterized by inflammation, fibrosis and dysfunction of exocrine glands such as tear and salivary glands. SS is defined as primary SS when it progresses alone without any other rheumatic disease finding, while the definition of secondary SS is used in the presence of another accompanying autoimmune disease. One of the most disturbing symptoms of SS is hyposalivation, xerostomia and dysphagia due to hypofunction of salivary glands. While xerostomia is the patient's subjective perception of dry mouth, hyposalivation is also evaluated objectively by salivary flow rate measurement methods. Studies have reported that 0.9% to 64.8% of patients with SS experience xerostomia and 32% to 72% of them experience dysphagia. It was planned as a randomized controlled study to examine its effect on dysphagia.

Detailed description

Sjögren's syndrome (SS) is a chronic, systemic and autoimmune disease characterized by inflammation, fibrosis, and dysfunction of exocrine glands such as tear and salivary glands. One of the most disturbing symptoms of SS is hyposalivation, xerostomia, and dysphagia due to the hypofunction of salivary glands. While xerostomia is the patient's subjective perception of dry mouth, hyposalivation is also evaluated objectively by salivary flow rate measurement methods (Pinto, 2021). Studies have reported that 0.9% to 64.8% of patients with SS experience xerostomia and 32% to 72% of them experience dysphagia (Orellana et al, 2016). With the reduction of saliva, patients may experience difficulties in tasting, chewing, swallowing, speaking, and using prosthesis in patients using prostheses (Pinto, 2021). All these negatively affect the quality of life in patients with SS and their treatment is of great importance (Milin et al, 2016; Pinto, 2021). The treatment of dry mouth in patients with SS consists of pharmacological and non-pharmacological stimulation of the salivary glands and the use of artificial saliva preparations (Ramos\_casals et al, 2020). Pharmacological methods used in patients with SS have been shown to reduce dry mouth, but these methods are mostly recommended in severe cases (Ramos\_casals et al, 2020; Depinoy et al, 2021). In cases where pharmacological methods are not used, non-pharmacological methods such as taste stimulation (lozenge) and mechanical stimulation (gum) are also recommended in the control of dry mouth (Ramos\_casals et al., 2020). It is known that chewing gum increases saliva secretion in studies conducted for different patient groups. used in the treatment of xerostomia in patients with SS, but no study has been found examining the relationship between chewing gum and salivation, xerostomia, and dysphagia in patients with SS (Ramos\_casals et al, 2020). In the literature review, no study was found in which the effects of the tongue, lip, and jaw exercises on salivation, xerostomia, and dysphagia were evaluated in any patient group. This study was planned to examine the effects of chewing gum and tongue, lip, and jaw exercises on salivation, xerostomia, and dysphagia in patients with SS.

Interventions

BEHAVIORALTongue, lip, chin exercise group

In order to evaluate the effect of chewing gum and tongue, lip and chin exercises on salivary flow rate, xerostomia and dysphagia, both intervention groups will work in a determined time frame daily.

Design outcomes

Primary

MeasureTime frameDescription
Simulated and Unsimulated Salivary Flow RateAt the first interview, stimulated and unstimulated salivary flow rate of the patients will be measured. In the second interview after 15 days, stimulated and unstimulated salivary flow rate will be measured to observe the change in salivary flow rate.Unstimulated Salivary Flow Rate: The patient will be placed in the Fawler position. Individuals will be asked to spit into the graduated tube for 5 minutes to collect saliva samples. The amount of saliva accumulated in the tube will be divided by 5 and the amount of saliva per minute (ml/min) will be calculated. Stimulated Salivary Flow Rate: The patient will be placed in the fawler position. Warning for collection of saliva samples will be provided with sugar-free gum. Individuals will be asked to hold the gum in their mouth until it becomes soft, chew for a few seconds, and swallow the first saliva formed. Then, they will be asked to continue the chewing movement using both sides of the jaw for 5 minutes and spit the saliva formed into the graduated tube at short intervals. The salivary flow rate will be calculated as ml/min by dividing the amount of saliva obtained after 5 minutes of chewing by the time.

Secondary

MeasureTime frameDescription
XerostomiaIt will be measured 2 times with a scale, with an interval of 15 days.Xerostomia is the patient's subjective perception of dry mouth. The Xerostomia Inventory 11 will be used to evaluate xerostomia. Each item describing the symptoms will be marked between 1 and 5 points according to the degree of severity. The result is an overall score ranging from 11 to 55 points. A higher total score indicates more severe symptoms are present.
Oral health-related quality of lifeIt will be measured 2 times with a scale, with an interval of 15 days.It is the effect of diseases, deficiencies and inadequacies related to oral and dental health on the quality of life. Oral Health Impact Profile will be used. Items will be answered with points between 0 and 4. The lowest possible score is 0, while the highest score is 56. A high total score indicates a poor oral and dental health-related quality of life.
DysphagiaIt will be measured 2 times with a scale, with an interval of 15 days.It is a disorder in which swallowing time is prolonged and more force is used to swallow than normal. The Eating Assessment Tool is used to evaluate dysphagia symptom severity and response to treatment. Each item is scored from 0 to 4. The total score ranges from 0 to 40. A score approaching 0 in the questionnaire indicates that the severity of the swallowing disorder decreases, and a score closer to 40 indicates that the severity of the swallowing disorder increases.
