Insulin dependent diabetes mellitus is a severe disease that raises blood glucose levels because of hyperglycemia and insulinopenia. Fluctuations in water and electrolyte levels may result in xerostomia and other changes in the salivary composition. Since diabetes has an influence on oral health, it is important for the dentist to be aware of newer advances in the field of diabetes and to recognize specific oral problems related to diabetes. Thus, the dentist becomes an important part of the health care team for the patients with diabetes. Aim: The present study correlated salivary flow rate, salivary pH and total salivary antioxidant levels and dental caries in type I diabetic patients. Method: A total of 200 children that included 100 known diabetic children (study group) and 100 healthy children (controls) of both the sexes and from similar socioeconomic backgrounds formed the part of this study. Dental caries was assessed using DMFT index. The salivary total anti-oxidant level was estimated using phospho molybdic acid using spectrophotometric method. The salivary flow rate was recorded using the Zunt method and the salivary pH using the pH indicating paper. The results were statistically analyzed using t-test. Conclusions: The analyzed parameters showed increase in salivary anti-oxidant levels, reduced salivary flow rate, increase incidence of dental caries, salivary pH was decreased when compared to the control group.

Leukemia constitutes approximately 30% of all childhood cancers and Acute Lymphoblastic Leukemia(ALL) is the most common type of malignancy. Oral dryness, ulceration, increased dental decay seen is due to altered salivary flow rate and buffering capacity in these children. Oxidative stress may play an important role in the malignancies resulting in onset of inflammatory oral pathologies. Saliva constitutes first line of defense against free radical-mediated oxidative stress. The present study attempted to relate the oral health status, salivary flow rate, salivary pH, gingival health status, dental caries experience and total salivary antioxidant levels in ALL children. A total of 120 children aged 4-10 years (90 leukemic children, study group and 30 normal healthy siblings, control group) were divided into 4 groups of 30 each. Oral health status, gingival status and dental caries experience was recorded followed by un-stimulated saliva collection. Total antioxidant capacity of un-stimulated saliva was evaluated. The results depicted deterioration in oral health status, gingival status and increased dental caries experience in leukemic children. Salivary flow rate, salivary pH and total salivary antioxidant levels were lowered in leukemic children when compared with control group.

Salivary flow rate, pH, and buffering capacity are associated with dental caries, but studies from the cystic fibrosis (CF) literature are inconclusive regarding these salivary factors and caries. The aim of this study was to evaluate these factors and their associations with dental caries in individuals with CF. Unstimulated whole saliva was collected from individuals aged 6-20 years at Seattle Children's Hospital CF Clinic, USA (n = 83). Salivary flow rate was measured in milliliters per minute. Salivary pH was assessed using a laboratory pH meter. Buffering capacity was assessed by titration with HCl. The outcome measure was caries prevalence, defined as the number of decayed, missing, or filled primary and permanent tooth surfaces. Spearman's rank correlation coefficient and the t test were used to test for bivariate associations. Multiple variable linear regression models were used to (1) run confounder-adjusted analyses and (2) assess for potential interactions. There was no significant association between salivary flow rate or buffering capacity and caries prevalence. There was a significant negative association between salivary pH and caries prevalence, but this association was no longer significant after adjusting for age. There was no significant interaction between salivary flow rate and buffering capacity or between antibiotic use and the 3 salivary factors. Our results indicate that unstimulated salivary factors are not associated with dental caries prevalence in individuals with CF. Future studies should investigate other potential saliva-related caries risk factors in individuals with CF such as cariogenic bacteria levels, salivary host defense peptide levels, and medication use.

Objective: This study aimed to analyze the concentration and activity of carbonic anhydrase (CA) VI in the saliva of school children. We investigated the relationship among caries, CA VI concentration/activity, flow rate, pH, and buffering capacity. Materials and Methods: Seventy-four school children were divided into a caries-free group and a caries group. Clinical examinations were conducted by one examiner according to World Health Organization criteria + early caries lesions. Salivary flow rate, pH, and buffering capacity were analyzed. Salivary CA VI concentration and activity were evaluated by ELISA and zymography, respectively. The data were analyzed using Student's t test and the Mann-Whitney test, and Pearson and Spearman correlation analyses were also done. In multivariate modeling, associations between variables were expressed as odds ratios. Results: The results showed that salivary flow rate, salivary pH, and BC were significantly higher in the saliva of caries-free children. Also, the salivary CA VI concentration was significantly higher in the saliva of caries-free children. The salivary CA VI activity was higher in children with caries. We found a negative correlation between BC and dental caries. Also, in the caries group we found a positive correlation between the concentration and the activity of CA VI and a negative correlation between BC and CA VI activity. A negative correlation between salivary pH and CA VI concentration was observed in the caries-free group. A high activity of CA and a low salivary flow rate were associated with dental caries. Conclusion: These results support the conclusion that dental caries is highly affected by the activity of CA VI in saliva as well as by the salivary flow rate.

Sugar Levels

Data from the Ministry of Health of the Republic of Indonesia in 2009 shows that national sugar consumption per capita reaches 12kg / year. Snacks consumed mostly were based on sucrose sugar and it turns out that sucrose is increasing the insidens of caries because sugar-based foods and drinks cause acid-resistant bacteria to obtain a suitable environment for growth. To overcome this problem sucrose was replaced with alcohol sugar such as xylitol, especially in chewing gum. However, it is still unknown the effect of xylitol on saliva. The purpose of this study was to see whether there were differences in salivary characteristics after consuming paraffin, xylitol chewing gum and sucrose chewing gum by looking at salivary pH values, reducing sugar levels in saliva and salivary flow rates. Saliva collection is done by spitting method then the total volume is divided by the time of collection to get the flow rate of saliva. Salivary pH is measured using a pH meter while reducing sugar levels are measured using the Benedict's test. The sample for this study consisted of 50 Ukrida FK students. The results of this study indicate that the highest salivary flow rate is after chewing xylitol chewing gum. While the reducing sugar levels in saliva are only found after chewing sucrose chewing gum. For salivary pH values, after chewing sucrose chewing gum the most acidic pH was obtained when compared to after chewing paraffin and xylitol chewing gum. From the research that has been done, after consuming paraffin, xylitol chewing gum and sucrose chewing gum, the highest salivary flow rate was obtained after consuming xylitol chewing gum, while the lowest was after consuming paraffin. Meanwhile, the highest pH value of saliva was after consuming paraffin and the lowest was after consuming sucrose chewing gum. Meanwhile, reducing sugar levels in saliva was only found after consuming sucrose chewing gum and was not found after consuming paraffin and xylitol chewing gum. From this study it can be concluded that there are differences in the characteristics of saliva among FK Ukrida students after consuming paraffin, xylitol chewing gum and sucrose chewing gum.

Introduction: Lemon juice contains citric acid. It is a highly antibacterial organic acid by gargling with, will be able to decrease the spreading of Staphylococcus aureus colony in saliva. The acid stimulation of lemon juice able to increase salivary secretion. The purpose of this study was to see the effect of gargling lemon juice of 100%, 50%, 25%, and 12.5% concentrations towards the salivary flow rate, salivary pH, the number of Staphylococcus aureus colony, and also, correlation between salivary flow rate and pH, salivary flow rate and number of Staphylococcus aureus colony, and salivary pH and number of Staphylococcus aureus colony. Methods: This research conducted with a pre-and-post-test group design. Saliva was taken from 24 subjects before and after the subjects gargled with lemon juice. Measurements performed were salivary flow rate per minute, and salivary pH (using pH Hanna Instrument). The Staphylococcus aureus bacteria were placed in a Mannitol Salt Agar for 24 hours at 370C temperature, then the number of the colonies were counted (x103 CFU). Results: The Wilcoxon test results showed that lemon juice with 100%, 50%, 25%, and 12.5% concentrations significantly increased the salivary flow rate and decreased the number of Staphylococcus aureus colony (p < 0.05). The result of the paired t-test showed that lemon juice with 25% and 12.5% concentration decreased the salivary pH significantly (p<0,05). The Pearson’s correlation results showed no significant correlation between salivary flow rate and salivary pH, flow rate and the number of Staphylococcus aureus colony, and salivary pH and number of Staphylococcus aureus colony. Conclusion: Lemon juice can decrease the salivary pH and the number of Staphylococcus aureus colony, but increases the salivary flow rate. It is considered to be good enough as one of the ingredients of mouthwash.Keywords: Flow rate, lemon, pH, saliva, Staphylococcus aureus
