ABSTRACT Objectives: The aim of this study is to evaluate the salivary flow rate and gustatory changes in HIV-positive patients on highly active anti-retroviral therapy (HAART) and without HAART. We also correlated CD4 count and salivary flow rate and gustatory function in both groups. Methods: Sample size for each group was thirty. After obtaining informed consent, we measured salivary flow rate using Schimer's method and gustatory function using four tastants (sweet, sour, bitter, and salty) of different concentrations. The readings were recorded at 0 month, 2nd, 4th, and 6th month interval. The data obtained was statistically analyzed. Results: The mean salivary flow rate was decreased more in Group I as compared to Group II. The mean identification score for sweet, salty, sour, and bitter was significantly higher in Group II than Group I. The mean detection threshold score for sweet, salty, sour and bitter taste was comparatively higher in Group I than Group II. The Pearson's correlation analysis showed inverse relation between age and salivary flow rate in Group II. No significant correlation was observed in CD4 count and salivary flow rate. Conclusion: Along with routine oral health appraisal in seropositive patients, evaluation of salivary flow rate, and taste abnormalities should also be considered an integral part of patient assessment.

Aim: This preliminary study aimed to estimate and correlate the relationship between salivary flow rate and levels of salivary triglycerides, cholesterol and total lipids in children with and without early childhood caries. Study design: Ninety children aged 3 – 6 years were divided into three groups of 30 each based on their decayed missing filled tooth (dmft) score, group I (dmft score = 0), group II (dmft score ≥4 and ≤ 9) and group III (dmft scores ≥ 10). Whole unstimulated saliva was collected in a sterile graduated cup over a period of 5 minutes and was quantitatively analyzed for levels of salivary triglycerides, cholesterol and total lipids. Data obtained was subjected to statistical analysis by one way ANOVA, Post-Hoc tukey and Pearson’s correlation test. Results: Salivary flow rate was 1.20±0.36, 1.01±0.37 and 0.86±0.31 ml/min in group I, II and III respectively. The mean levels of salivary triglycerides in group I, II and III was 3.57±0.43mg/ml, 6.11±1.70mg/ml and 6.03±1.73 mg/ml, respectively. The mean levels of salivary total lipids were higher in group II and III, ie 22.51±2.87 mg/ml and 22.68±2.54 mg/ml respectively. The mean level of salivary cholesterol was highest in group III (8.03±2.91 mg/ml). Salivary triglycerides and total lipids showed a significant positive correlation with dmft scores of children (p≤ 0.001). Salivary cholesterol also had a positive association with dental caries experience of children but was not significant. There was a negative correlation between salivary flow rate and levels of salivary triglycerides, cholesterol and total lipids. Conclusion: Children with ECC (group II and III) had lower salivary flow rate and higher levels of salivary triglycerides and total lipids compared to caries free children (group I). Levels of salivary cholesterol did not differ between caries free and children with ECC.

The Impact

Background: The current study has been conducted to estimate the impact of Catha Edulis Forsk (simply known as khat) on pH and saliva flow rate in teeth unaffected by caries among patients from Arab, Yemen, consuming the plant. The goal was to evaluate the relation of these indicators with gene manifestation of CHRM1 and CHRM3, which contributes to the regulation of saliva secretions. Methods: Overall, 60 respondents aged between 27 and 54 years were selected for the research. They were distributed among two groups, group I and group II, including 30 respondents equally. Group I incorporated respondents consuming no khat, having teeth caries, adequate saliva flow, and generally, healthy oral cavity. In turn, group II incorporated respondents consuming khat having caries-free teeth, inadequate saliva flow and relatively unhealthy oral cavity. Saliva samples were taken from all respondents. They were analyzed for indicators of flow rate as well as pH of saliva. Salivary gland biopsy specimens have also been taken. The whole RNA was allocated, cDNA synthesized and reinforced to estimate the gene manifestation of CHRM1 and CHRM3. Results: A considerable rise in the mean salivary flow rate along with a drastic decline in the mean salivary pH within caries-free teeth among the respondents consuming khat was observed during the study. The mRNA expressions CHRM1 and CHRM3 were significantly increased among participants consuming khat. Results were contrasted to the control group of patients not consuming khat. Conclusion: The characteristics of salivary flow rate, pH, and caries-free teeth have been related to the gene manifestations of CHRM1 and CHRM3 in respondents consuming khat.

Xylitol, a five-carbon sugar polyol, is a white crystalline carbohydrate known since a century ago. The objective is to assess the efficacy of xylitol based oral hygiene products (chewing gum, mouthwash, and toothpaste) on salivary parameters - pH, Resting Salivary Flow Rate (RFR) and Stimulated Salivary Flow Rate (SFR) among subjects with medium cariogenic risk. The study recruited sixty participants who were divided into 3 groups of 20 individuals each. Subjects in Group I, Group II, Group III were given xylitol toothpaste, xylitol mouth-wash & toothpaste, and xylitol chewing-gum & toothpaste respectively for 3 weeks. The salivary parameters - RFR, SFR, and pH were assessed before and after the use of xylitol-based products. All three groups showed an increase in the RFR, SFR, and pH after three weeks. RFR was found to be statistically significant in Group I (p=0.006), Group II (p=0.000), and Group III (p=0.000). SFR was found to be statistically significant in Group II (p=0.000) and Group III (p=0.000). pH was found to be statistically significant in Group I (p=0.002) and Group III (p=0.003). Xylitol is a well-known anti-caries agent, and it has been well documented in the prevention of caries. The present study was conducted in the light of these facts to compare the efficacy of different xylitol products concludes that chewing-gum is comparatively more effective than mouthwash and toothpaste.

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.

Background: Saliva is a complex secretion produced daily by the salivary glands. Saliva consists mainly of water, enzymes, ions and amino acids and performs several important functions in oral health. Objective: The aim of this study was to investigate the flow rate and concentrations of amylase and total proteins in the saliva of hospitalized patients due to AIDS complications. Methods: Ninety-three men and women (20-64 years of age) were divided into two groups (46 HIV-infected patients and 47 controls) and had salivary flow rate and levels of amylase enzyme and total proteins evaluated. Results: The mean salivary flow rate was lower in individuals with HIV when compared to controls (P < 0.05). No signifi- cant difference between amylase enzyme levels and total proteins were observed in the saliva of patients with HIV infection when compared to controls. Conclusion: Individuals with HIV / AIDS infection (in hospital treatment) suffer no interference in levels of amylase and total salivary proteins, but they have significantly reduced salivary flow.

Submandibular/sublingual saliva and blood were collected from five subjects after ingestion of 1 mg fluoride as NaF. An individual collection device, made from a silicone impression material, was used to collect the saliva in 10-minute samples, before and during 2 hr after the fluoride intake. In two separate experiments on each individual, submandibular/sublingual saliva was collected continuously at different flow rates: without stimulation and with gustatory stimulation. Blood was also collected at intervals throughout the experiments. The concentration of fluoride in the submandibularlsublingual saliva was less than that in the plasma but independent of salivary flow rate. The ratio between the saliva and plasma fluoride concentrations at the peak of the mean plasma fluoride concentrations was 0.55 ± 0.13 and 0.69 ± 0.11 in the experiments on unstimulated and stimulated salivary flow rate, respectively. The total amount of the ingested fluoride dose that was excreted through the submandibular/sublingual glands during 130 min was highly correlated with the salivary flow rate. The fraction of the ingested fluoride dose excreted in 2 hr was 0.04 ± 0.02% in the unstimulated saliva and 0.15 ± 0.09% in the stimulated saliva.

The aim of this study was to evaluate the oral sequelae of radiotherapy in patients treated between 1999 and 2003 for head and neck tumors. One-hundred patients (24 women, 76 men) ranging in age from 30 to 83 years (mean 59.2 years) were examined. Time since radiotherapy ranged from 1 to 72 months (mean 28 months). The total mean radiation dose received by the patients was 5,955 cGy. The evaluation protocol included anamnesis, intraoral and extraoral examination, measurement of stimulated salivary flow and salivary pH. Symptoms reported by the patients included dry mouth (68%), dysphagia (38%), and dysgeusia (30%). In 64% of the patients, the mean stimulated salivary flow rate was less than 0.7 ml/min. The mean salivary pH was 6.97 (± 0.714). Stimulated salivary flow increased with increasing postradiotherapy time (p < 0.05). The prevalence of mucositis was associated with higher radiation doses (p < 0.05), and the prevalence of atrophic candidiasis was related to a longer post-treatment period (p < 0.05). Two cases of recurrence of the primary tumor were detected during the study. The main effect of radiotheraphy in the head and neck region was a reduction of the salivary flow rate, even though our study demonstrated that there was a modest late improvement of the salivary flow.
