The Mean

Background: Increase in salivary flow accompanying complete denture insertion is a well-known phenomenon. Complete dentures act as a mechanical stimulant, increasing salivary flow after insertion. This study compares unstimulated and stimulated salivary flow rates before, during, and after insertion of a complete denture in different age groups.Method: Forty subjects meeting inclusion criteria were selected. Unstimulated saliva was collected first. Stimulation was produced by chewing paraffin wax and collected of saliva in a graduated container. This procedure was carried out before insertion, during insertion, 24 hours after, and 7 days after insertion of complete dentures. The study data were entered, edited, and coded in Microsoft Excel. The unstimulated and stimulated salivary flow rate was compared at different time intervals.Result: Unstimulated salivary rate was lowest before denture insertion with mean values of 0.27ml/minute. The highest flow rate was recorded during denture insertion (mean values of 0.60 ml/minute). The mean unstimulated salivary flow rate 24 hours after denture insertion was higher than 7 days after denture insertion. The mean stimulated salivary rate was lowest before denture insertion (mean values of 0.59 ml/minute). The highest flow rate was recorded during denture insertion (mean values of 0.93 ml/minute). There was a declining trend in salivary flow rate after denture insertion i.e. 0.86 ml/minute to 0.75ml/min after 24 hours and 7 days of denture insertion. A gradual decrease in salivary flow rate with an increase in age was noted but the association of age with salivary flow rates was not statistically significant.Conclusion: There was an increase in both unstimulated and stimulated salivary flow rate after insertion of complete denture and age does not affect salivary flow rates before, during (immediately after), 24 hours after, and 7 days after denture insertion.

Abstract Background Xerostomia is associated with several diseases and is a side effect of certain drugs, resulting from reduced saliva secretion. Often, aged and sometimes younger people suffer from (idiopathic) xerostomia. Chewing gum and sucking pastilles may relieve symptoms of xerostomia by increasing the salivary flow rate due to the mechanical effect of sucking and gustatory stimulation. Swallowing problems and the urge to cough or experiencing a tickling sensation in the throat might be alleviated through a reduction in dry mouth symptoms. We investigated whether a pastille containing four polysaccharides increased the salivary flow rate and relieved the symptoms of dry mouth. Methods Participating subjects with xerostomia were randomized into two equally balanced treatment groups. Subjects received the pastille on Day 1 and a control product (Parafilm®) on Day 3, or vice versa. Unstimulated saliva was collected every 2.5 min for 0–10 min. Stimulated saliva was collected after subjects sucked the pastille or the control product. The salivary flow rate was determined gravimetrically, and, in parallel, the feeling of dry mouth was assessed using a visual analog scale. Saliva surface tension was measured in pooled saliva samples (0–5 min of sampling). Additionally, in stimulated saliva from six subjects who sucked the pastille, the presence of the main ingredient—gum arabic—was examined by Raman spectroscopy. Results Chewing the pastille significantly increased the mean salivary flow rate by 8.03 g/10 min compared to the mean changes after chewing the control product (+ 3.71 g/10 min; p < 0.0001). The mean score of dry mouth was significantly alleviated by the pastille (− 19.9 ± 17.9 mm) compared to the control product (− 3.3 ± 18.1 mm). No difference between the two products was seen regarding the saliva surface tension. Gum arabic was present in the saliva of all investigated subjects for up to 10 min after sucking the pastille. Conclusions The pastille was well tolerated and effective in increasing the salivary flow rate and reducing mouth dryness after sucking. These results were in line with the detection of the main ingredient, gum arabic, in saliva for up to 10 min after sucking the pastille.

Abstract Background Salivary function has been suggested to be associated with cognitive impairment. However, the effect of salivary flow rate (SFR) on cognitive impairment remains unclear. This study aimed to investigate whether SFR is associated with cognitive impairment among Korean elders. Methods This cross-sectional study included 649 elders aged 65 and older in the Korean community-dwelling population. Cognitive impairment was assessed using the Mini-Mental Status Examination. Unstimulated SFR was measured and dichotomized. Denture status, age, sex, education level, smoking, drinking, diabetes, hypertension, and obesity were considered confounders. Multivariable logistic regression analysis was applied to assess the adjusted association. Stratified analysis by sex and denture status was performed to clarify the effect modification. Results Participants without cognitive impairment showed a higher SFR level than those with cognitive impairment (0.81 mL/min for non-cognitive impairment versus 0.52 mL/min for cognitive impairment, p < 0.001). After controlling for confounders, participants with low SFR (< 0.3 mL/min) were more likely to have cognitive impairment by 1.5 times than participants with normal SFR (odds ratio [OR] = 1.5, confidence interval [CI] = 1.05–2.10). The association of low SFR with cognitive impairment was higher in women and dentate participants: about 10% higher in women (OR = 1.63, CI = 1.07–2.50) and about 22% higher in dentate participants (OR = 1.82, CI = 1.41–2.90). Conclusions Salivary flow rate is independently associated with cognitive impairment among Korean elders. The association was modified in females and dentate elders. Physicians and dentists should consider low SFR and cognitive impairment as a risk factor between them in clinics.
