Objective. To investigate the association of salivary flow rates with oral symptoms and oral mucosal status. Study design. The study population included 462 Israeli subjects attending a xerostomia clinic. After patient history and oral mucosal examination, major gland sialometry, and complementary tests, patients were divided into 6 groups: drug-induced salivary gland hypofunction (SGH), Sjögren syndrome (SS), radiation-induced SGH, idiopathic SGH, xerostomia without SGH, and control. Results. Oral mucosal alterations were more prevalent in all SGH groups than in the control group. Oral symptoms (except speech impairment) were more frequent in all SGH groups. The postradiation group showed the highest frequency of oral mucosal alterations and of swallowing and mastication complaints. Individuals complaining of xerostomia (compared with those who did not) displayed lower major salivary gland flow rates and a higher frequency of oral mucosal alterations Conclusions. Presence of oral mucosal alterations may help but are not enough to identify patients for further evaluation of SGH. Difficulties in mastication and swallowing are most specifically related to advanced SGH.
Factors associated to salivary flow alterations in dry mouth female patients
Revista Dor, 2014
BACKGROUND AND OBJECTIVES: Saliva plays an important role in oral health; it is involved in lubrication of the oral mucosa, protection against infections, transport of nutrients and digestive enzymes, remineralization of teeth, as well as aiding in chewing, swallowing and speech. Reductions in the amount of saliva are known to increase the risk of oral diseases. This study investigated the factors associated to salivary flow alterations and its relationship with age, burning mouth syndrome, psychiatric and sleep disorders, systemic diseases and chronic drug use. METHODS: A total of 30 patients complaining of dry mouth without unbalanced systemic diseases were included. Questionnaires regarding socio-demographic data, xerostomia, burning mouth, depression and anxiety symptoms, and sleep disturbances were applied. Measures of salivary flow rates were obtained using spit method. Correlation of hyposalivation and quantitative data was determined using a multivariate regression model.
Clinical factors influencing the resting and stimulated salivary flow
Open Journal of Stomatology, 2012
Objective: The objective of this study was to examine the clinical and immunological factors influencing sialometry in xerostomia patients. Method: The association between sialometry and other clinical examinations were investigated in a cross-sectional study. A total of 179 dry mouth patients showing hyposalivation who underwent a clinical examination were enrolled in this study. Multiple regression analyses were employed to examine the relative contributions of clinical and immunological factors including age, gender, parotid sialography, labial Salivary gland biopsy, anti-Ro/SS-A antibodies, and anti-La/SS-B antibodies to the resting (RSF) or stimulated saliva flow rate (SSF). Results: An increase of the stage of sialography, the grade of a labial biopsy, and the presence of anti-La/SS-B antibody had a significant correlation with a decrease of sialometry. Results of the multiple regression analysis showed that age (standardized coefficient = −0.244), grade of lip biopsy (−0.189), and anti-SS-B antibody (−0.171), were significantly associated with the RSF. The stage of sialography (−0.423) and age (−0.169) were significantly related to the sialometry in the SSF according to a multiple regression analysis. Conclusion: The results of this study suggest that the measurement of RSF reflects the immunological factors and SSF reflects the damage to the parotid gland.

The aim of the present study was to assess the occurrence of reported subjective oral dryness in relation to objective sialometric values in a randomly selected group and a dental care-seeking group. A questionnaire assessing subjective oral dryness was sent out to a randomly selected sample of 200 individuals. The dental care-seeking group was recruited from among patients attending the Department of Oral Diagnostics, Malmö University. A total of 200 patients were asked to participate in the present study. In total, 312 individuals (78%) completed the survey and 157 individuals agreed to participate in the complementary clinical examination that included measures of salivary flow rate. The reported subjective oral dryness was 20% and 28.6% for the randomly selected group and the dental care-seeking group, respectively. No statistically significant differences were found between the two study populations with regard to percentage of reported subjective oral dryness, and stimulated a...
Unstimulated salivary flow rate, pH and buffer capacity of saliva in healthy volunteers
Revista Espanola De Enfermedades Digestivas, 2004
Objectives: to assess the salivary flow rate, pH, and buffer capacity of healthy volunteers, and their relationships with age, gender, obesity, smoking, and alcohol consumption, and to establish the lower-end value of normal salivary flow (oligosialia).
Standardization of a simple method to study whole saliva: clinical use in different pathologies
Acta odontológica latinoamericana : AOL, 2006
The present study describes a methodology to assess the salivary flow rate in humans. Whole saliva was obtained from the floor of the mouth with a plastic dental ejector and a vacuum pump. Forty healthy subjects of both sexes and 51 patients with different pathologies (Sjögren Syndrome, Thyroid Dysfunction, Diabetes Mellitus) were included in the study. It was demonstrated that basal salivary flow rate was stable five minutes after the insertion of the oral ejector Salivary flow rate did not show significant differences between sexes and was independent of the negative pressure level of the vacuum pump. Stimulated salivary flow rate was quantified over a period of 3 minutes, starting 5 minutes after the introduction of the oral device. The stimulus was paper filter disks soaked in citric acid (2%) placed on the tongue dorsum. The use of this method confirmed the reduction of salivary flow rate in patients with Sjiigren Syndrome. In addition, a significant reduction in salivary flow ...
Reduction in unstimulated salivary flow rate in burning mouth syndrome
British dental journal, 2014
Burning mouth syndrome (BMS) is a chronic condition of burning of the tongue and oral mucosa. It is often accompanied with complaints of xerostomia, although it is unknown whether the dryness is a sensory change similar to the burning sensation or due to hyposalivation. To determine whether there is change in salivary flow rate, whole salivary flows were measured in BMS patients. A clinical ambispective study was conducted. Patients' clinical files were reviewed for stimulated and unstimulated whole salivary flow. Patients were divided into four groups based on diagnosis into Sjögren's syndrome (SS), BMS, BMS taking oral drying medications (BMS-med), and control (C). Whole stimulated (SF) and unstimulated flow (USF) measurements were collected and compared among groups. Data were analysed with ANOVA, Levene's test, Tukey's test and Games-Howell test. Twenty SS, 22 BMS, 24 BMS-med and 15 C were included in the study. SF was significantly lower in SS (0.59 ml ± 0.36) c...
