Inclusion criteria
Inclusion criteria: Well-controlled blood disease and collagen disease. No acute oral manifestations of dental caries, periodontal disease, or oral mucositis. These are the main selection criteria, and the details of the target population are shown below. Patients with xerostomia (1) Patients with chronic graft-versus-host disease and Sjogren's syndrome who have subjective symptoms of xerostomia and whose salivary secretion during stimulation is less than 10 ml/10 min in the gum test and less than 2 g/2 min in the Saxon test. No history of treatment with salivary stimulants, artificial saliva or oral moisturizers for xerostomia. (2) Males and females between the ages of 20 and 90 years old at the time of consent, who, after receiving sufficient explanations about participation in this study, and with sufficient understanding by the subject himself/herself, can give written consent of his/her own free will. (3) Those who have given their consent to the examination at a regular dental or oral surgery clinic. (4) Patients who are able to attend regular outpatient clinics for examination and treatment. (5) Patients with no abnormalities in opening and closing movements, swallowing, or respiratory function (6) Patients must be able to hold their breath for 5 seconds. Basis for setting For (1), patients who have been diagnosed with a target disease will be selected. For (1), to select patients who have been diagnosed with the target disease, and for (2) to (6), from an ethical perspective. Rationale for setting 1) Patients who do not have chronic graft-versus-host disease or Sjogren's syndrome, do not have subjective symptoms of xerostomia, and whose salivary secretion during stimulation is 10 ml/10 min or more in the gum test and 2 g/2 min or more in the Saxon test. No history of treatment with salivary stimulants, artificial saliva or oral moisturizers for xerostomia. 2) Males and females between the ages of 20 and 90 years old at the time of consent, who, after receiving sufficient explanations about participation in this study, and with sufficient understanding by the subject himself/herself, can give written consent of his/her own free will. 3) Those who have given their consent to the examination at a regular dental or oral surgery clinic. 4) Those who are able to attend regular outpatient clinics for examination and treatment. 5) Patients with no abnormalities in opening and closing movements, swallowing, or respiratory function. 6) Patients must be able to hold their breath for 5 seconds. Basis for setting (1) For (1), to select healthy persons. For (2) to (6), the selection was made from an ethical perspective.

A history of treatment with salivary stimulants, artificial saliva or oral moisturizers for xerostomia. (2) Males and females between the ages of 20 and 90 years old at the time of consent, who have received sufficient explanation for participation in this study, and whose written consent of their own free will cannot be obtained after they have fully understood it. (3) Patients who are unable to give consent for examinations at regular dental and oral surgery clinics. (4) Patients who are unable to attend regular outpatient clinics for examination and treatment (5) Patients with abnormalities in opening and closing movements, swallowing, or respiratory function (6) Patients who are unable to hold their breath for 5 seconds Basis for setting For (1), patients with xerostomia who do not meet the eligibility criteria will be excluded. For (1), to exclude patients with xerostomia who do not meet the eligibility criteria. For (2) to (6), from an ethical perspective. Healthy subjects 1) Patients who do not have chronic graft-versus-host disease or Sjogren's syndrome, have subjective symptoms of xerostomia, and whose salivary secretion during stimulation is less than 10 ml/10 min in the gum test and less than 2 g/2 min in the Saxon test. A history of treatment with salivary stimulants, artificial saliva or oral moisturizers for xerostomia.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. To investigate the relationship between salivary secretion at rest, salivary secretion during stimulation, expiratory water vapor volume, and oral water vapor volume in patients with xerostomia and healthy subjects, and to objectively quantify the degree of dryness in the mouth. 2. To evaluate the performance of a newly developed device for detecting the amount of water vapor in exhaled air. Basis for setting There is no method to objectively quantify the degree of dryness in the oral cavity, and this is a newly developed device. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. To examine the relationship between resting salivary volume, stimulated salivary volume and xerostomia (scale value). 2. To verify the relationship between exhaled water vapor and oral water vapor measurements and xerostomia (scale value). 3. To examine the construction of a system that can classify the severity of the disease based on 1. and 2. and evaluate diagnosis and treatment. Basis for setting It is necessary to objectively quantify the degree to which a moist environment is created by secreted saliva in order to classify the severity of the disease and to evaluate diagnosis and treatment. | — |
