Purpose: We aimed to investigate the objective cutoff values of unstimulated flow rates (UFR) and stimulated salivary flow rates (SFR) in patients with xerostomia and to present an optimal machine learning model with a classification and regression tree (CART) for all ages. Materials and Methods: A total of 829 patients with oral diseases were enrolled (591 females; mean age, 59.29±16.40 years; 8~95 years old), 199 patients with xerostomia and 630 patients without xerostomia. Salivary and clinical characteristics were collected and analyzed. Result: Patients with xerostomia had significantly lower levels of UFR (0.29±0.22 vs. 0.41±0.24 ml/min) and SFR (1.12±0.55 vs. 1.39±0.94 ml/min) (P<0.001), respectively, compared to those with non-xerostomia. The presence of xerostomia had a significantly negative correlation with UFR (r=-0.603, P=0.002) and SFR (r=-0.301, P=0.017). In the diagnosis of xerostomia based on the CART algorithm, the presence of stomatitis, candidiasis, halitosis, psychiatric disorder, and hyperlipidemia were significant predictors for xerostomia, and the cutoff ranges for xerostomia for UFR and SFR were 0.03~0.18 ml/min and 0.85~1.6 ml/min, respectively. Conclusion: Xerostomia was correlated with decreases in UFR and SFR, and their cutoff values varied depending on the patient's underlying oral and systemic conditions.

Objectives: This study was to investigate the level of xerostomia and depression in the elderly people and to determine the relationship between xerostomia and depression. Methods: The subjects were 238 subjects(86.5%), who were 65 years or older with mean age of 73.6 years. Data was collected using a self administrated questionnaire from September 14 to September 23, 2005. Perception of xerostomia was measured by questionnaire, and depression was measured using the 20-items CES-D. The data were analysed with t-test, one-way ANOVA, pearson correlation coefficient and multiple regression using the SPSS 12.0 Windows. Results: Regarding xerostomia, the subjects was a mean of 7.87 out of a maximum 12 points. The level of depression in the group of people 65 years or older was 21.51 out of a maximum 60 points. Xerostomia was positive related depression in this study. Perceived oral health and xerostomia had a significant impact on depression. Conclusion: Based on the findings, the perception of xerostomia is strongly associated with depression. These results suggest that oral health promotion should be considered various psychological factors related xerostomia in elders.

Xerostomia is usually caused by a reduced salivary flow or by changes in the biochemical composition of saliva. Halitosis or oral malodor is an offensive odor usually originating from the oral cavity. Halitosis can lead to anxiety and psychosocial embarrassment. The occurrence of halitosis closely related with intraoral conditions including the presence of xerostomia. Especially, the relationship between xerostomia and halitosis is prominent in elderly patients receiving polypharmacy with at least two systemic diseases. This study is a review of the update literature of xerostomia and halitosis. A large number of papers have been searched and identified using the words , , , , , , and . Papers not relevant to the issue were removed reducing the entries to 79 only. Most of identified papers were systematic reviews, non-systematic reviews, and observational studies. With a proper diagnosis, identification of the etiology and timely referrals certain steps are taken to create a successful individualized therapeutic approach. It is significant to highlight the necessity of an interdisciplinary method for the treatment of xerostomia and halitosis to prevent misdiagnosis or unnecessary treatment. This article concisely focuses on the development of a systemic flow of events to come to the proper treatment of the xerostomia and halitosis.

Objectives : The purpose of this study was to examine the effect between job stress in jobholders and xerostomia. Methods : 250 jobholders living in Jecheon city were the subjects of this questionnaire. The questionnaire was made up of three contents and 37 items: general characteristic(13), job stress(14), degree & behavior of xerostomia(10). The data were analyzed by two-sample t-test, one-way ANOVA to examine the subjects general characteristics, job stress and degree of xerostomia and were analyzed by Chi-square test to examine the subjects general characteristics, job stress and behavior of xerostomia. Results : Only 215 jobholders were evaluated due to inadequate responses. The results were as follow. 1. As general characteristic of jobholder, male(83.7%) were more than women(16.3%), 30~39 year-old(47%) in age variable, university graduation(63.7%) in the last educational background variable, 2~3 million won(31.2%) in the month average income variable, 1~5 year(33.5%) in tour of duty variable, non-smoker(47.9%) in smoking variable were most. Married(58.6%) were more than unmarried(39.5%). Alcoholic(69.8%) were more than non-alcoholic(30.2%). 2. As classification of job stress, high strain group was 28.4%, active group was 26%, low strain group was 24.2%, passive group was 21.4%. 3. Analysis of effect between general characteristic and degree & behavior of xerostomia showed smoker were statistical significantly higher than non-smoker on 'dry eat', 'Am-sal', 'Night awake', 'Slip-liq'and 'Gumcandy'(p<0.05) and showed alcoholic were statistical significantly higher than non-alcoholic on 'Dry PM', 'Night awake, $H_2O$-bed'(p<0.05). 4. Analysis of effect between job stress and degree & behavior of xerostomia showed hight strain group were statistical significantly higher than low strain group on 'Dry PM', 'Dry-day', 'Am-sal', 'Eff-life'and 'Night awake'(p<0.05). Conclusions : As high strain group were higher than other groups on degree & behavior of xerostomia, stress would be factor that have an effect on xerostomia. Thus consider and management of stress is necessary for diagnosis and treatment of xerostomia.

After 40 years of age, the saliva glands are aged and the saliva is not made enough to cause xerostomia symptoms. Side effects such as hypertension medication or diuretics that the elderly take mainly can cause xerostomia syndrome. In addition, autoimmune diseases, diabetes, anemia, depression and other common diseases that cause xerostomia symptoms. If the saliva secretion is insufficient, tooth decay and gum disease are likely to occur, and the digestive ability of the saliva is also reduced due to the lack of amylase, which is a digestive element. Once the degenerated salivary gland is restored to its normal state, it is difficult to recover. In this paper, we give electrical stimulation to the masseter which is in contact with the large pituitary gland, and stimulate the salivary gland to the utmost by using speech recognition using words corresponding to oral gymnastics. Use the STM32F407VG to implement a system to relieve xerostomia.

Xerostomia is defined as the subjective complaint of dry mouth with or without hyposalivation, which is insufficient salivary secretion from salivary gland. Xerostomia can lead to multiple oral symptoms such as dental caries, halitosis, burning mouth syndrome, and oral candidiasis, which can significantly impact the well-being of patients, especially in geriatric patients who may already have compromised health. Clinical findings of xerostomia include decreased salivary flow and alterations in salivary composition. These changes can lead to various oral health problems such as dental caries, periodontitis, swallowing and speaking difficulties, taste disturbances, halitosis, mucosal diseases, and burning mouth syndrome. Recognizing these clinical manifestations is essential for early diagnosis and appropriate management. Although several reasons and risk factors have been suggested for xerostomia such as aging, chemo-radiation therapy, systemic disease, and Sjögren's syndrome, the polypharmacy is recently highlighted especially in elderly patients. Understanding the etiology and risk factors associated with xerostomia is crucial for effective management. To manage xerostomia patients, a multidisciplinary guideline should be established beyond dental care. Through this literature review, we summarized consideration for diagnostic, therapeutic, nursing essentials for the clinical guideline. By addressing the underlying causes and implementing appropriate treatment strategies, healthcare professionals can improve the quality of life for individuals suffering from xerostomia.

Objectives: This case report examines the effects of traditional Korean medicine for unspecified tremor with xerostomia caused by psychometric drug intake. Methods: A patient who suffered from unspecified tremor with xerostomia caused by psychometric drug intake was treated with acupuncture, pharmacopuncture, and traditional Korean medicine for 30 days. We provided the patient with herbal medicines including Ondam-tang-gagam (溫膽湯加減), Pumsimgieum-gagam (忿心氣陰加減), and Hoichunyanggyeok-san-gami (回春凉隔散加味). Symptoms were charted and evaluated using the Yin-deficiency questionnaire score, Yin-deficiency scale score, dry mouth symptom questionnaire, and visual analogue scale. Results: After treatment with Korean Medicine and pharmacopuncture, the frequency and degree of tremor has decreased, and degree of Xerostomia also improved. The Scores of Yin-deficiency questionnaire score, Yin-deficiency scale score, dry mouth symptom questionnaire, and visual analogue scale were also improved. And we could see reduction in the level of distribution of gastrointestinal heat at Digital Infrared Thermal Imaging test. The patient's Symtoms (Xerostomia as well as unspecified tremor) were improved after treated with Korean Medicine and pharmacopuncture. Conclusion: Korean medicine treatments may be valuable for xerostomia caused by psychometric drug intake.

Objectives The aim of this study is to analyze the characteristics of the tongue coating pattern in the elderly patients with xerostomia. Methods Ninety-six elderly patients with xerostomia were recruited by advertisement and they visited the oral diseases clinics at Kyung Hee University Korean Medicine Hospital and Kyung Hee University Hospital at Gangdong from November, 2011 to August, 2013. After signifying the assent, the subjects who passed screening were enrolled this study. The subjects were evaluated on their clinical characteristics of xerostomia using visual analogue scale for xerostomia, dry mouth questionnaire, unstimulated salivary flow rate. In addition, Yin-deficiency questionnaire was used to evaluate the Yin-deficiency state and Winkel tongue coating index and Digital Tongue imagin system were used to measure the tongue coating of patients. Results The proportion of women was higher than that of men, and there were few smokers in this study population. This population had chronic and relatively severe xerostomia symptoms. Also, thin coating pattern was showed in this elderly patients with xerostomia and this result was regarded to the influence of Yin-deficiency. The thin coating patten was observed in the group with higher Yin-deficiency score. There was no difference in tongue coating between the hyposalivation and normosalivation group. Conclusion In the elderly patients with xerostomia, Yin-deficiency is might be considered as one of the main cause of xerostomia. Hence, it is thought that this patients showed the thin coating pattern. This results could be used in diagnosis and treatment for the elderly patients with xerostomia in traditional Korean medicine.

Xerostomia is a relatively common oral disease that causes various problems such as pain, discomforted, tissue damage, and infection. When the activity of AQPs, which plays an important role in the microbial channel transmembrane activity in tissues, decreases saliva secretion and the oral cavity dryness occurs. In this study, we observed whether there was a change in tissue through the expression level of AQP-5 in the submandibular gland in the 4-DAMP-induced xerostomia model. First, in order to construct a xerostomia model, 4-DAMP (1 mg/kg) and 20% urethane (0.5 mL/kg) were administered intraperitoneal (i.p.) to experimental animals. To observe the changes in the submandibular gland was excised, H&E staining was performed and protein quantitation analysis was performed using the submandibular tissue to observe the changes in AQP5 protein expression involved in changes in saliva secretion. Also, cinnamaldehyde (5, 12.5, 25 and 50 mg/kg) dissolved in 20% DMSO, in distilled water for each concentration, and then orally administered at a dose of 1 mL for biopsy and protein quantitative analysis. As a result, it was observed that the submandibular tissue, a model of xerostomia was wider than the naïve group. And then western blot analysis, the expression level of AQP5 decreased in the 4-DAMP group compared to the naïve group, and the expression increased in the group administered orally with cinnamaldehyde. Therefore, administration of 4-DAMP resulted in histological changes for xerostomia, and cinnamaldehyde would be a material that can be developed by reducing xerostomia.
