Unstimulated and chewing-stimulated whole saliva samples were obtained from 42 healthy Caucasians; 21 were between 18 and 35 years of age, and 21 between 65 and 83 years of age. The unstimulated salivary flow rate was significantly lower in the aged group, but the stimulated flow rate was significantly higher in the aged than in the young group. Both groups showed significantly increased flow during salivary stimulation. MG1 and MG2 concentrations in unstimulated and stimulated saliva samples were significantly lower in the aged group. There were no significant correlations between salivary flow rates and MG1 and MG2 concentrations.

Saliva Flow

The aim of this study was to examine salivary flow rate and its association with the use of medication in a representative sample of 76-, 81-, and 86-year-old subjects, totaling 368. In this study, 23% (n = 80) of the subjects were unmedicated. From one to three daily medications were used by 47% (n = 168) and more than four medications by 30% (n = 104). The most commonly used medications were nitrates, digitalis or anti-arrhythmic drugs (47.7%), analgesics and antipyretics (32.6%), and diuretics (29.5%). The mean number used daily was significantly higher in 86-year-olds than in the two younger age groups (p < 0.01). No significant differences in this respect were found between genders. Among the unmedicated subjects, 76-year-olds had significantly higher stimulated salivary flow rates than did the 81-year-olds (p < 0.05). Unmedicated women showed significantly lower unstimulated (p < 0.01) and stimulated flow rates than did men (p < 0.05). Stimulated salivary flow rate was also significantly higher in the 76-year-old medicated subjects than in the medicated 86-year-old subjects (p < 0.05). No statistically significant differences were found in unstimulated salivary flow rates among the three age groups. Medicated women showed significantly lower unstimulated salivary flow rates than men (p < 0.001), although the difference in stimulated saliva flow was not significant. A statistically significant difference in unstimulated and stimulated salivary flow rates was found between unmedicated persons and those who took from four to six, or more than seven, prescribed medications daily.

The salivary flow rate (SFR) in healthy individuals may vary according to different factors. There is a scarcity of studies from different geographical areas that analyze SFR variations in children. The aim of this study was to verify stimulated salivary flow rate (SFR) variations in 6 to 12-year-old children, from four different public schools of Rio de Janeiro and correlate these data to gender, age, type of dentition, and health status. Clinical data were taken from the children's medical records that were kept at those schools. Oral examination and sialometry were performed in every child. Salivary flow rate was obtained by chewing-stimulated whole saliva under standard conditions. There were significant differences in SFR according to age (p = 0.0003). Six and 12-year-old children showed the lowest SFR, and when they were excluded from the analysis, no significant differences were found (p = 0.21). There were also significant differences in SFR among children from different public schools (p = 0.0009). The gender did not show any correlation to SFR, even when children were stratified by age (p = 0.36). Correlation between SFR and deciduous, mixed or permanent dentition was not found as well. These results show that the analyzed clinical variables did not seem to influence SFR in this children population.

The Relationship

The amount of fluoride retained in the mouth following the application of dentifrices, mouthwashes, etc. may be important in determining their anticaries efficacy. In this study we investigated the relationship between the salivary flow rate and salivary fluoride clearance. Ten adults tested six mouthrinses, consisting of aqueous sodium fluoride solutions (0.013, 0.026 mol/l) with and without added sodium chloride (1.28 mol/l) or sucrose (0.44 mol/l), in a randomised order. Prior to each test, subjects swallowed, rinsed for 2 min with 2 ml water and then expectorated into a preweighed container to obtain a measure of initial saliva flow rate. Next, the procedure was repeated using one of the test rinses. Finally, samples of unstimulated whole saliva were collected for up to 3 h after each mouthrinse application and analysed for fluoride. Salivary fluoride concentrations were significantly lower after application of mouthrinses that contained either sucrose or NaCl, both of which compounds markedly enhanced salivary flow, than after the use of corresponding mouthrinses without any additive. Area under the salivary fluoride clearance curve (AUC) values were inversely correlated with salivary flow rate on an individual basis (p < 0.01). The observed behaviour could not be completely attributed to treatment dilution by saliva at the time of application.

Therapeutic Doses

Changes in stimulated and non-stimulated whole saliva flow rates were measured in 11 Hodgkin's disease patients who received therapeutic doses of radiation to a mantle field at the M. D. Anderson Hospital in Houston, Texas. Salivary flow rates were examined before, during, and after radiotherapy. Mean flow rate reductions of 54% for non-stimulated saliva and 55.7% for paraffin-stimulated saliva were observed post-radiotherapy. Flow rates had not returned to pre-irradiation levels in any of the patients who were observed for two to three months after completion of therapy. Results obtained from this preliminary study indicate that most patients who receive therapeutic doses of radiation to a mantle field experience a significant reduction in salivary output which is manifest during the period of treatment and persists for a period of at least two to three months post-radiotherapy.

Sjögren‘S Syndrome

Patients with the salivary component of Sjögren's syndrome (SS) develop chronic xerostomia, which causes oral symptoms and functional impairment in approximate proportion to its severity. The purpose of this double-blind study was to determine whether an electrical stimulus applied to the tongue and hard palate by a battery-operated device (SAL II, Biosonics, Inc.) could stimulate salivary flow in subjects with generally severe SS. Twenty-nine patients with the salivary component of SS (diagnosed as the presence of focal chronic sialadenitis in a labial salivary gland biopsy specimen with a focus score of > 1 focus/4 mm2) were randomly assigned active or placebo devices, which they used for three minutes, three times a day for four weeks. Whole saliva flow rates were measured at weeks 0, 2, and 4 by collection of whole saliva both before and after stimulation with the device. Twenty-four subjects completed the study. The change in mean post-stimulation flow rate from week 0 to week 4 was greater for the 13 subjects using an active device (0.08 ± S.D. 0.08 gl2 min, to 0.24 ± 0.33 gl2 min) than for the 11 subjects using a placebo device (0.11 ± 0.15 gl2 min, to 0.08 ± 0.18 gl2 min) (p = 0.04). However, the magnitude of the mean difference was small, because three subjects using active devices responded and others did not. Only five subjects, all using active devices, reported a subjective increase in the amount of their saliva. The results of this study indicate that some SS patients with residual salivary flow show a significant response to electrical stimulation, but others with low or absent whole saliva flow rates do not respond.

Background: Human immunodeficiency virus (HIV) infection increases vulnerability to opportunistic viral infection, including Human cytomegalovirus (HCMV) infection, that has been detected in saliva. The HCMV envelope glycoprotein B (gB) is highly immunogenic and has been associated with HCMV-related diseases. Purpose: The purpose of this study is to assess the prevalence of HCMV and gB-1 genotype in the saliva of HIV/AIDS patients and to analyse their relationship with xerostomia and salivary flow rate (SFR). Methods: This cross-sectional study involved 34 HIV/AIDS patients. Saliva was tested for the presence of HCMV DNA using PCR microarrays, and nested PCR for gB-1 genotype detection. Xerostomia was measured using a Fox’s questionnaire. Unstimulated whole saliva flow rate was measured by means of the spitting method. Results: The composition of the research population consisting of 73.5% males and 26.5% females with HIV/AIDS. HCMV was found in 64.7% of HIV/AIDS patients, while gB-1 genotype was detected in 59.1%. Xerostomia was closely associated with the presence of HCMV in saliva (p<0.05), but not with gB-1. There was no significant relationship between xerostomia and SFR rates in the research subjects with HCMV positive saliva (p> 0.05). Conclusion: The presence of xerostomia-associated HCMV in saliva was elevated among HIV/AIDS patients. Further investigation is required to identify other gB genotypes that may be responsible for xerostomia and SFR changes in HIV/AIDS patients.

Endocrine and biological changes occur in postmenopausal women, the production of steroid sex hormones that affect the health of the oral cavity, with the reduction of all or part of estrogen resulting in xerostomia (dry mouth). The treatment of Xerostomia was carried out using local, mechanical and chemical stimulation. The purpose of this study was to determine the effect of gargling of green tea steeping on salivary flow rates in postmenopausal women with xerostomia at Darussalam Public Health Center in Medan.This is an experimental study using the design of control group, pretest-posttest and the non-probability of purposive sampling. Fourty menopausal women with xerostomia were used as sample. The treatment group gargled with green tea steeping while the control group gargled with distilled water. Saliva was collected into the pots for three minutes before and after treatment by spitting method. The analytical test used was the paired T-test and the unpaired.The results showed that there was an increase in salivary flow rate with green tea brushing rinse by 0.281750 ml/min and with aquades rinsing by 0.03335 ml/min. Furthermore, there was an effect of gargling with green tea steeping, namely an increase in the flow rate of saliva and this research can be an alternative treatment to relieve xerostomia in menopausal women.The green tea gargling was better in stimulating salivary flow rate.

Summary Background The purpose of the present study was to assess saliva reliability in diagnosis and monitoring type 2 diabetes instead of blood. Methods Blood and unstimulated whole saliva were collected from 300 type 2 diabetic subjects and 300 healthy controls in fasting. Then, the salivary flow rate was calculated. All parameters including glucose, urea, amylase, total protein, albumin, C-reactive protein (CRP), immunoglobulin A (IgA), potassium, calcium and chloride were assessed in the supernatant, using an autoanalyzer. Oral exam was conducted by a single examiner on full mouth excluding third molars. Statistical analysis was performed by the SPSS 20.0 version. Results Saliva screening showed that glucose, urea, amylase, total protein, potassium, calcium and chloride were significantly higher in patients compared to controls (p < 0.05). Whereas, the IgA level and salivary flow rate were significantly reduced in patients (p < 0.05). No significant difference was found in albumin and CRP levels (p = 0.05). There was a significant positive correlation between salivary and plasma glucose levels (r = 0.887, and r = 0.900, p < 0.001), as well as, salivary and blood urea (r = 0.586, and r = 0.688, p < 0.001) in patients and controls, respectively. Conclusions From this study, saliva could be suggested as a useful diagnostic tool for type 2 diabetes.

Introduction: Saliva contains numerous proteins and electrolytes that may serve as biomarkers of pathological conditions, including periodontitis. Saliva flow also influenced by pathological conditions, such as periodontitis. Therefore, saliva analysis, as one of the biomarker source needs to be examined. This study was aimed to analyse the differences salivary inorganic ions levels (calcium, phosphate, and bicarbonate) and salivary flow rate in periodontitis and non-periodontitis patients. Methods: This research was analytic-observational using two groups, the healthy periodontal group consisting of 21 people (PI scores between 0-0.2) and the periodontitis group consisting of 21 people (PI scores between 0.7-8.0). Unstimulated saliva was collected using a passive drolling method. The calcium, phosphate and bicarbonate levels in the saliva were analysed using UV/Vis spectrophotometers. Results: Calcium, phosphate and bicarbonate levels in saliva were different between groups. Salivary flow rate also different between groups. There was a significant difference (p = 0.00) in the calcium, phosphate and bicarbonate levels between groups (t-test), and also significantly different (p = 0.000) salivary flow rate between groups. The higher the salivary flow rate, the higher the levels of calcium, phosphate and bicarbonate would be. Conclusion: Periodontitis condition increases the level of salivary inorganic ions and salivary flow rate because of periodontal inflammation. This inflammation mainly because of plaque deposition and calculus. Increased level of inorganic ions in the saliva such as calcium, phosphate, and bicarbonate, and also the salivary flow rate indicates the existence of a periodontal disease.

The main aim of our study was to perform a biochemical analysis of the saliva and to assess potential impact on oral health, particularly cariogenic issues, in patients with salivary secretory dysfunction such as primary Sjogren�s syndrome (pSSj). Consecutive pSSj and healthy age-matched controls were prospectively assessed for (i) whole saliva flow rates (unstimulated, RFR, and stimulated, RFS), pH and composition; (ii) cariogenic scores - decayed, missing and filled tooth surfaces (DMFS index), Silnes and Loe bacterial plaque index (PI). Salivary flow rates were significantly lower in pSSj for both unstimulated and stimulated tests (p[0.05), with a drop in pH as compared to healthy controls (p[005). Abnormal inorganic and organic saliva composition was reported in all cases comprising higher sodium, lower potassium and chloride concentrations, higher amylase activity and lower total protein (p[0.05). Statistically significant higher cariogenic scores particularly DMFS, were demonstrated in all pSSj (p[0.05). In conclusion, patients with pSSj are at increased risk to develop cariogenic issues due to both quantitative and qualitative salivary changes.
