The Influence of Black Tea on Secretory IgA from Saliva in Caries and Caries-Free Subjects

The crucial role of saliva in the prevention of dental caries is associated with the regulation of its flow rate as well as salivary protein. Black tea, derived from the plant Camellia sinensis, contains catechins and has been shown to have a beneficial effect on saliva in preventing tooth decay. Nevertheless, research on the oral health benefits of black tea is still limited. This study aimed to investigate the effects of black tea (Camellia sinensis) on salivary pH (potential hydrogen), salivary flow rate, lysozyme, and sIgA levels in caries and caries-free patients. The study used a quasi-experimental design with a pre-test and a post-test. Twenty six subjects (male or female) were selected and divided into two groups (caries and caries free), thirteen subjects for each. Saliva samples were obtained before and thirty minutes after tea consumption. The flow rate of saliva was measured by dividing the weight of saliva collected by the time. At the same time, secretory immunoglobulin A (sIgA) levels were analyzed by enzyme-linked immunosorbent assay (ELISA). The t-dependent and t-independent tests and Mann-Whitney tests were selected to evaluate the effect of drinking black tea on salivary flow rate and sIgA value. The results showed that black tea significantly increased salivary flow rate but did not significantly affect the concentration of sIgA. No statistically significant differences in salivary flow rate and sIgA were observed between patients with and without caries after tea consumption. Although the concentration of sIgA did not demonstrate a significant change, however, the salivary flow rate was significantly enhanced. Therefore, drinking black tea did not negatively affect the saliva in the oral cavity, suggesting it can be a good option for daily consumption due to its protective role against dental caries.

Photobiomodulation efficacy of major salivary glands in children with caries activity: study protocol for randomized, double-blind, placebo-controlled, parallel-group clinical trial

Background: Dental caries is one of the most prevalent diseases among children worldwide. Saliva plays a significant role in the demineralization/remineralization of the dental surface. Several salivary characteristics, such as flow rate, pH, and buffering capacity, provide relevant information regarding the development of carious lesions. Photobiomodulation has shown promising results in improving salivary flow rate and buffer capacity in the adult population. Purpose: of this trial was to evaluate the efficacy of photobiomodulation of the major salivary glands on salivary parameters in children with caries. Methods: This protocol details a randomized, double-blind, parallel-group, controlled trial that evaluated salivary parameters through photobiomodulation in children. Fifty 6- to 12-year-old participants will be randomly divided into two groups:1) photobiomodulation experimental group (G1) (n=25) and 2) photobiomodulation placebo group (G2) (n=25). Infrared light will be applied at 16 intra-and extraoral points and placebo, respectively. Unstimulated salivary samples will be collected before and immediately after application once a week for three consecutive weeks. Salivary samples will be analyzed for their flow rate, pH, and buffering capacity. The primary outcomes are the differences in salivary flow rates between G1 and G2. The secondary outcomes are differences in salivary pH and buffering capacity between G1 and G2.Discussion: The results of this clinical trial will offer evidence for the efficacy of photobiomodulation in salivary parameters and to support decision-making regarding non-invasive treatments to control dental caries.

Comparison of salivary flow rate and pH between healthy subjects and tobacco and areca nut chewers.

Tobacco and areca nuts release carcinogens, which cause alterations in saliva. Evaluation of these changes through estimation of salivary flow rate and pH was performed in tobacco and areca nut chewers and apparently healthy subjects. The study group for this comparative study comprised 60 subjects with 20 areca nut chewers (group 1), 20 tobacco chewers (group 2), and 20 non-tobacco and areca nut chewers (group 3) in the ages between 18 and 75 years. After collection of saliva from each subject, the salivary flow rate (SFR) was measured by using graduated tubes, whereas salivary pH was measured using a digital salivary pH meter. Tukey HSD post hoc test was performed for comparison of mean SFR and mean pH between study group subjects. Analysis of variance (ANOVA) test was used to find the mean difference in SFR and pH in duration, intensity, and frequency among various types of areca nut and tobacco users. A "P" value of less than 0.05 was considered as statistically significant. The mean age among groups 1, 2, and 3 was 37.70 ± 10.44, 39.75 ± 10.16, and 37.90 ± 10.52 years, respectively, with a statistically insignificant difference. The mean salivary flow rate (ml/20 min) was maximum in group 3 (13.23), followed by group 2 (11.75) and group 1 (10.48), with the statistically significant difference as P < 0.05. The mean salivary pH was maximum in group 3 (7.07), followed by group 2 (6.86) and group 1 (6.49), with the statistically significant difference as P < 0.05. Long-term use of tobacco and areca nuts in a chewable form can significantly reduce the salivary flow rate and salivary pH. Hence, these measurements can be used as chair side, non-invasive measures for assessing pathological changes in oral mucosa linked to vulnerable effects among people addicted to these adverse habits; thereby, early re-organization can prevent mobility and mortality.

Salivary parameters and periodontal inflammation in obstructive sleep apnoea patients

The aim of this cross-sectional study was to objectively assess the salivary flow rate and composition and periodontal inflammation in obstructive sleep apnoea (OSA) patients. The subjects, who underwent whole-night polysomnography or polygraphy, were referred for saliva sampling and periodontal examination. According to the severity of OSA based on the Apnoea Hypopnea Index (AHI) value, the subjects were classified into groups: no OSA (AHI < 5; N = 17), mild to moderate OSA (AHI 5–29.9; N = 109), and severe OSA (AHI > 30; N = 79). Salivary flow rate, pH, salivary electrolytes, and cortisol were measured from collected saliva samples. Periodontal examination included assessment of the number of teeth, dental plaque, bleeding on probing and periodontal measurements: gingival recession, probing pocket depth, clinical attachment level (CAL) and periodontal inflamed surface area (PISA) score. There were no significant differences in salivary flow rate, salivary pH, salivary electrolyte concentrations or electrolyte ratios among the groups classified according to the severity of OSA. However, subjects without OSA had higher salivary cortisol concentrations than OSA groups (p < 0.001). Increased plaque scores were associated with a higher AHI (r = 0.26; p = 0.003). According to the salivary flow rate, subjects with hyposalivation and reduced salivation had higher concentrations of salivary electrolytes and lower salivary pH than subjects with normal salivation. Subjects with hyposalivation had an increased Mg/PO4 ratio (p < 0.001) and a reduced Ca/Mg ratio (p < 0.001). Furthermore, subjects with severe OSA tended to have higher CALs and plaque volumes. In conclusion, under pathological conditions, such as OSA, multiple interactions might impact salivary flow and electrolyte composition. Complex interrelationships might affect the integrity of oral health, especially considering OSA severity, inflammation, concomitant diseases and medications.

Understanding If Differences in Salivary Flow Rate and Total Protein Content Triggered by Biological Factors (Sex and Age) Affect Aroma Perception and the Hedonic and Emotional Response of Wine Consumers.

The relationship between oral physiology (e.g., salivary protein content) and aroma perception over wine consumption was investigated in previous work. However, the relationship between oral physiology and the consumer’s response to wine is unknown. Additionally, age–gender differences might affect oral physiology and, therefore, inter-individual differences in the consumer’s enjoyment of wine. The aim of this work was to study the effect of biological individual factors such as sex and age on salivary flow rate and total protein content, on wine retronasal aroma perception and on the hedonic and self-reported emotional consumer response to wine. Additionally, the relationship between saliva composition, aroma perception and liking was also assessed. Results showed that age and sex influenced saliva composition and aroma perception in wine consumers in the case of red but not white wines. Younger females reported higher aroma intensity of the black pepper descriptor compared to older females. Correlation analysis confirmed the relationship between salivary flow rate and aroma perception and between the salivary protein content and wine acceptability. The interactions between wine polyphenols–saliva–aroma that occurred in the mouth during the oral processing of wine might partially explain these results, although further research will be required to confirm this hypothesis.

EFFECT OF SCREEN TIME ON ORAL HEALTH STATUS IN CHILDREN-AN EXPERIMENTAL STUDY WITH SALIVARY ANALYSIS

Background: The prospect of side effects associated with the electromagnetic waves emitted by the mobile phones is a questioned issue. The current study was designed to assess the impact of mobile phone use on salivary concentrations of amylase in children. Methods: The children were divided into dominant and non-dominant groups based on the questionnaire. For each subject, saliva samples from the dominant and non-dominant mobile phone users were collected. Salivary flow rate and salivary concentrations of proteinamylase were measured. Data were analysed using one-way analyses of variance and t-tests conducted with the statistical software version 18 (SPSS Chicago, Illinois, USA). Results: Salivary flow rate and salivary concentrations of protein amylase were significantly higher in the non- dominant group than the dominant group. Conclusion: The dominant mobile phone use was associated with differences in salivary flow rate and salivary concentrations of amylase. Significant changes in salivary amylase and salivary flow rate suggest the adverse effects of the high use of cell phones on cell health in children.

Salivary biomarkers in children with juvenile idiopathic arthritis and healthy age-matched controls: a prospective observational study

Monitoring the immune system’s regulation and signaling using saliva could be of interest for clinicians and researchers. Saliva, a biofluid with close exchange with serum, is influenced by circadian variance and oral factors such as masticatory function. This study investigated the detectability and concentration of cytokines and chemokines in saliva in children with juvenile idiopathic arthritis (JIA) as well as saliva flow and the influence of orofacial pain on saliva flow. Of the 60 participants (7–14 years old) enrolled, 30 had a diagnosis of JIA and active disease, and 30 were sex- and age-matched healthy controls. Demographic data and three validated questions regarding presence of orofacial pain and dysfunction were recorded. Stimulated whole saliva was collected and analyzed using a customized R&D bead-based immunoassay with 21 targeted biomarkers. Fourteen of these were detectable and showed similar levels in both children with JIA and controls: TNF-alpha, TNFRSF1B, MMP-2, MMP-3, IL-1alpha, IL-1beta, IL-6R alpha, IL-8, S100A8, CCL2, CCL3, IL-10, CCL11, and CXCL9. In addition, there was no difference in salivary flow rate between groups, but there was an association between orofacial pain and reduced saliva flow rate for both groups.Trial registration: ClinicalTrials.gov Protocol id: 2010/2089-31/2.

An assessment of unstimulated salivary flow rate, IgA and clinical oral dryness among active and passive smokers.

The aim of this study was to assess the impact of smoking on the whole salivary flow rate (SFR), IgA levels and clinical oral dryness (COD) among active and passive smokers. The participants were categorized as active smokers (N = 54) or passive smokers (N = 163). Saliva was collected in tubes and placed in ice storage at -70°C. Salivary IgA levels were assessed in duplication using the enzyme linked immunosorbent assay (ELISA) method. Following the saliva sample collection, the subjects were assessed for COD using the COD score, SFR and caries. Chi-square test, the t-test and ANOVA were employed to compare the clinical impact of the smoking status associated with specific variables (smoking status, number of cigarettes, active caries, gender, age, COD score, IgA level and SFR). A p-value of <0.05 was considered significant. Two hundred and seventeen subjects with the mean age of 32.86±6.30 years, with 145 males (66.8%) and 72 females (33.2%), were included in the study. Among the active smokers, 88.8% were males compared to 11.2% females. The active smokers had the mean age of 32.52 years, a COD score of 1.43, an IgA level of 1.39 g/l, and a SFR of 0.37 ml/min. Among the passive smokers, 59.5% were males and 40.5% were females, with the mean age of 32.97 years, a COD score of 0.87 g/l, an IgA level of 1.47, and a SFR of 0.42 ml/min. Active caries showed a positive correlation with the number of cigarettes, with significance in the >35 years age group (p < 0.05). The study demonstrated significant differences in SFR, IgA and COD scores among the active and passive smokers. The number of cigarettes had a negative impact on saliva production, IgA levels, the oral health status, and the progression of caries with respect to age and gender. Smoking potentially leads to xerostomia associated with active caries. Int J Occup Med Environ Health. 2022;35(1):39-51.

Effect of Systemic Administration of Amitriptyline on Oral Microbes in Rats.

Amitriptyline is a major tricyclic antidepressant that is also used to relieve chronic orofacial pain. Recently, alterations in gut flora due to various antidepressants have been demonstrated. However, it remains unknown how antidepressants affect the oral environment, including microbiota and innate immunity. The aim of this study was to investigate the effects of amitriptyline on oral microflora and antimicrobial peptides. Sprague-Dawley rats were intraperitoneally injected with amitriptyline for 2 weeks. The DNA extracted from the oral swabs were used to perform 16SrRNA sequencing to evaluate the oral microbiome. Quantitative RT-PCR was performed to evaluate the mRNA levels of antimicrobial peptides in the buccal tissues. No significant differences in salivary flow rates were observed between the amitriptyline and control groups. Taxonomic analysis showed significant alterations in bacteria such as Corynebacterium, Rothia, and Porphyromonas due to amitriptyline administration. The beta diversity showed significant differences between the amitriptyline and control groups. Additionally, the predicted metagenome functions were significantly different between the two groups. The mRNA expression levels of antimicrobial peptides in the amitriptyline group were significantly higher as compared to controls. Systemic administration of amitriptyline may affect the oral environment, including oral microbes and innate immunity in the oral mucosa.

Is Chinese herbal formula (nourishing Yin therapy) effective and well tolerated as an adjunct medication to hydroxychloroquine in the treatment of primary Sjögren’s syndrome? A meta-analysis of randomised controlled trials

Background:Previously, data mining methodology was used to identify 71 patented prescriptions in Chinese patent databases, indicating that Yin-nourishing therapy (YNT) may be an adjunct medication to hydroxychloroquine in the treatment of primary Sjögren’s syndrome (pSS). The purpose of this study was to investigate effects of the addition of YNT, which includes tonifying liver and kidney therapy (TLKT) and replenishing Qi and nourishing Yin therapy (RQNYT), in the treatment of pSS.Methods:Fourteen databases (including Chinese, English, Japanese, Korean and Latin databases) were searched to identify randomised controlled trials (RCTs) of YNT plus hydroxychloroquine (YNTPH) versus hydroxychloroquine alone in patients with pSS. Relevant publications up to June 2021 were selected. A meta-analysis and trial sequential analysis (TSA) were performed using Review Manager 5.3, Stata 14.0 and TSA 0.9 software. The quality of identified studies was assessed based on the Cochrane risk of bias tool and GRADE (grading of recommendations, assessment, development and evaluation) criteria.Results:We included five RCTs with a total of 345 participants. Pooled results indicated significant differences in short-term outcomes, which were assessed via European League Against Rheumatism (EULAR) Sjögren’s Syndrome Patient Reported Index (ESSPRI), EULAR Sjögren’s Syndrome Disease Activity Index (ESSDAI), tear production, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and immunoglobulin G (IgG) results when YNTPH was compared with hydroxychloroquine use alone (p < 0.05). No significant difference in salivary flow rate was reported. The most common side effect reported for both groups was gastrointestinal reaction. Sensitivity analyses suggested that heterogeneity might be ascribed to clinical methodology. Subgroup analyses revealed heterogeneities regarding salivary flow rate were eliminated. TLKT appeared to be better than RQNYT for improving salivary flow rate. TSA only supported changes in ESSPRI, ESSDAI and ESR values. For all studies, the quality of evidence was low.Conclusion:YNTPH may be an effective complementary therapy. Current evidence, however, is insufficient for determining whether YNTPH is more effective than hydroxychloroquine alone. Well-designed RCTs are needed to determine the role of YNT in pSS treatment.

Whey Protein Derived Mouthdrying Found to Relate Directly to Retention Post Consumption but Not to Induced Differences in Salivary Flow Rate.

Whey protein is fortified into beverages to provide functional benefits, however, these beverages are considered mouthdrying. To date whey protein derived mouthdrying has not been quantified using a ‘physical measure’ in parallel with rated perception. Saliva flow could also relate to whey protein derived mouthdrying, however this has not been previously tested as an intervention. Accordingly, volunteers (n = 40) tested mouthdrying in different whey beverages and the sensory profile was evaluated by a trained sensory panel (n = 10). Volunteers also rated mouthdrying combined with collection of saliva samples post beverage consumption to measure retention to the oral cavity. To modulate saliva flow rate, volunteers both chewed on parafilm (to increase saliva flow) and used cotton wool (to remove saliva) before tasting beverages and rating mouthdrying. Both the volunteers and sensory panel rated whey protein beverages (WPB) as significantly more mouthdrying than the control beverage (whey permeate). The significantly higher rating of mouthdrying from the volunteers coincided with significantly higher protein concentration in saliva samples post WPB consumption, supporting mucoadhesion as the mechanism. Modulating saliva flow did not lead to any difference in rated mouthdrying and future work would be beneficial to evaluate further the influence of natural variation in salivary flow rate.

Differences in salivary flow rate and pH between chewing gum of xylitol and sucrose in elementary school students in Makassar

Caries can be caused by various factors such as the amount of salivary flow, salivary acidity, etc. It needs to be known by chewing gum with xylitol and sucrose are most excellent to preventing caries in children. This study aimed to determine the difference of salivary flow while chewing xylitol gum and sucrose bubble gum in students of SD Inpres Toddopuli Makassar. This qualitative research with quase experimental studies method is the pre- and post-test design with control group. The sample criteria were children aged 9-12 years, has a superficial and media dental caries at least three teeth, did not another chewing gum about 60 minutes before examination, and willing to be research samples. As many as 30 samples each in grades 4, 5, and 6 chew xylitol gum on the first day and chew sucrose gum on the secong day of 5 minutes each. Saliva was collected on a cen-trifuge tube, observed amount and acidity of saliva. The results showed significants difference in the amount of salivary flow and acidity between xylitol chewing gum and sucrose chewing gum, namely there was different in amount of salivary flow (0.002) and for salivary pH value (0.000). It was concluded that children who chewed xylitol gum produce more saliva than sucrose chewed gum and sucrose gum had higher acidity than xylitol gum.

Assessment of Salivary Flow Rate in Patients with Chronic Periodontitis.

ABSTRACTBackground:Chronic periodontitis (CP) is an infectious disease, primarily affecting the attachment apparatus of the dentition, and is categorized into mild, moderate, and severe periodontitis on the basis of its severity. It is a well-established and proven fact that an adequate level of saliva is essential for maintaining the integrity of oral tissues including the periodontium. Although various factors, such as stimulation, circadian rhythm, diet, age, and drugs, can affect the salivary flow rate, many recent studies have provided evidence that it can be altered by pathological inflammatory conditions such as periodontal diseases. Therefore, this study has been undertaken to assess the unstimulated and stimulated salivary flow rate in the different clinical stages of chronic periodontitis.Materials and Methods:This study comprised 60 study participants, who were divided into four groups depending on clinical attachment level (CAL). In all, both unstimulated and stimulated saliva were collected, and the flow rate was expressed in milliliter per minute.Results:Statistical analysis was accomplished with Statistical Package for the Social Sciences (SPSS) software. One-way analysis of variance (ANOVA) was used to analyze differences in salivary flow rate among the groups. Statistical significance was set at P < 0.05. The amount of unstimulated saliva in healthy subjects, in mild, moderate, and severe periodontitis was 0.766, 0.400, 0.270, and 0.146 mL/min, respectively. Likewise, the amount of stimulated saliva in healthy subjects, in mild, moderate, and severe periodontitis was 1.017, 0.494, 0.347, and 0.236 mL/min, respectively.Conclusion:The study identified a significant decrease in both unstimulated and stimulated salivary flow rate with the severity of progression of chronic periodontitis.

Evaluation of oral stereognosis, masticatory efficiency, and salivary flow rate in complete denture wearers.

Aim:The aim of the present study was to evaluate the improvement in oral stereognostic ability, masticatory efficiency, and difference in salivary flow rate in nonexperienced denture wearers, before, after, and 6 months after rehabilitation with complete dentures.Settings and Design:Invivo – Observational study.Materials and Methods:Seventy edentulous subjects were selected who came for rehabilitation with complete dentures for the first time. The study was conducted in three stages–before denture insertion, after denture insertion, and 6 months after denture insertion. Oral stereognostic ability was evaluated by asking the subjects to identify six heat cured acrylic resin samples by oral manipulation without seeing it. The unstimulated salivary flow rate was estimated by measuring the time taken to collect 5 ml of the whole saliva. Masticatory efficiency of the subjects was assessed with the help of preweighed chewing gums. The chewing gums were desiccated after the chewing strokes and weighed again.Statistical Analyses Used:Data were tabulated and analyzed statistically using pairedt-test, one-way ANOVA test, and the post hoc test.Results:Oral stereognostic ability increased immediately on insertion of complete dentures and was still higher 6 months post insertion of dentures. Comparison of the means of masticatory efficiency after denture insertion and 6 months after denture usage gave highly significant values (p< 0.001). The salivary flow which increased immediately following denture insertion returned to almost normal 6 months after denture insertion.Conclusion:The study support the hypothesis that the presence of dentures improve oral sterognostic ability and masticatory efficiency.

Sampling was through a consecutive sampling technique in subjects aged ≥60 years living in Depok. Subjects were examined for their saliva’s volume, stimulated and unstimulated salivary analysis, pH, and buffer capacity. Subjects answered fox questionnaires about xerostomia and questionnaires about systemic diseases and medications.Results: Gender had a significant difference in salivary flow rate but was not significant to pH or buffer capacity. There were no significant differences between types of salivary profile among age, systemic diseases, and medications. The correlation coefficient between xerostomia and stimulated flow rate was higher (0.426) than the unstimulated flow rate (0.303).Conclusion: The unstimulated and stimulated flow rates exhibited a significant difference between men and women but did not differ significantly between age groups, systemic diseases, or medications. The pH and buffer capacity was not significantly different between sexes, age groups, type of systemic diseases, or medications. Xerostomia was associated with salivary flow rate.

The Effects of Tooth Brushing on Whole Salivary Flow Rate in Older Adults.

Objectives (1) To determine whether manual (MTB), or electric, tooth brushing (ETB) modulates whole salivary flow rate in older adults who are free of systemic disease. (2) To determine the duration of the brushing-related modulation of salivary flow rate. (3) To compare salivary flow rate modulation associated with MTB and ETB. Method Twenty-one adults aged 60 years and older participated in two experimental sessions during which they used a manual, or electric, toothbrush to brush their teeth, tongue, and palate. Whole salivary flow rates were determined using the draining method before, during, and after brushing. Differences in salivary flow rates across time periods, and between conditions, were examined using paired samples t-tests applying a Holm-Bonferroni sequential procedure (pcorr < 0.0045). The relationship between tooth brushing and age with respect to maximum salivary flow rate increase was examined using Pearson's correlation coefficient (p < 0.05). Results/Conclusion Whole salivary flow rates increased during, and for up to 5 minutes following, tooth brushing in adults aged 60 years and older who were free of systemic disease. The salivary effects of MTB and ETB were not significantly different. A moderate, positive correlation was observed between tooth-brushing-related maximum salivary flow rate increase and age.

The Effect Of Gargling Green Tea On Salivary Flow Rate On Female With Xerostomia At Puskesmas Darussalam Medan

Introduction: Saliva is important in maintaining the health of the oral environment. A reduction of the saliva flow by 40% to 50% will cause xerostomia. Xerostomia as the main complaint, experience by about 14%-46% of patients. The objective of this research is to find out the influence of green tea gargle to saliva flow rate in xerostomia patient. Materials and Methods: Green tea with the Latin name Camellia sinensis (L). Polyphenol compounds, catechins in this tea cause a bitter taste that can stimulate the central nervous system resulting in increased salivary secretion.

Effectiveness of transcutaneous electrical nerve stimulation on saliva production in post-radiated oral cancer patients

Aims and Objectives: To determine the effectiveness of transcutaneous electrical nerve stimulation (TENS) in stimulating salivary flow in post-radiated oral cancer patients, and to compare the salivary flow rate between unstimulated saliva and saliva stimulated with TENS in post-radiated oral cancer patients. Materials and Methods: In 30 patients who underwent radiotherapy for oral cancer, unstimulated saliva was collected every minute for 5 min in a graduated test tube. The TENS unit was activated and stimulated saliva was collected for 5 min in a separate graduated test tube, and the flow rate was compared with the unstimulated salivary flow rate. Results: A statistically significant improvement was seen in saliva production during stimulation (P < 0.001). In addition, statistically significant increase in TENS stimulated saliva was observed in patients aged ≥50 years compared to that in patients aged <50 years (P < 0.05). There was no significant difference in salivary flow rate between the two genders in both stimulated and unstimulated conditions, however, statistically significant increase in salivary flow rate was observed in males under stimulated condition (P < 0.01). Conclusion: TENS was highly effective in stimulating the whole salivary flow rate in post-radiated oral cancer patients. It is an effective supportive treatment modality in xerostomia patients caused by radiotherapy in oral cancer patients.
