The aim of this study was to determine salivary pH, buffering capacity and calcium levels in caries-free and caries-active children. We examined 80 children of both genders, 15 years of age. Subjects were divided into four groups as follows: caries-free females, caries-active females, caries-free males, caries-active males; each group consisted of 20 subjects. The unstimulated saliva sample was collected by the spitting method and then pH, buffering capacity and calcium in saliva was measured. The results showed that mean level of buffering capacity of saliva was decreased significantly in the caries-active group as compared to caries-free group. The obtained data showed that the mean levels of pH and calcium were decreased in the caries-active group as compared to the caries-free group, but the difference was not statistically significant. The saliva with its constituents plays an important role in maintaining oral and especially dental health. Salivary pH values were found to be higher in the caries-free group. In our study, there was no significant correlation of pH values and caries activity with gender. Buffer capacity values were significantly lower in the caries-active group than in the caries-free group. There were significant differences when the groups were compared in the caries-active group where buffer capacity values were higher in boys than in girls. Calcium content of saliva was higher in the caries-free group. The results obtained in this study related to the values of the pH, buffering capacity and calcium in saliva, may serve as parameters for determining the caries risk patients, and accordingly to plan and carry appropriate caries preventive measures.

Background: Renal failure is a process that expresses a loss of functional capacity of the nephrons, independently of its etiology. Although acute renal failure is reversible in the majority of cases, chronic renal failure presents a progressive course towards terminal renal failure. Hemodialysis is the most widely used technique leading to systemic alterations, oral complications and variations in the flow and composition of the saliva. The purpose of this study was to estimate salivary pH, buffering capacity, flow rate in chronic renal failure patients undergoing hemodialysis with its oral manifestation and caries prevalence. Methods: Saliva samples were collected from 40 patients with chronic renal failure undergoing dialysis and 40 healthy subjects after taking the informed consent. Saliva samples were then taken to the lab for processing. Salivary pH, buffering capacity and flow rate was estimated. DMFT was calculated. The statistical analysis was done using SPSS version 23. Results: A statistically significant rise in salivary pH, buffering capacity with decrease in flow rate was noted in chronic renal failure patients undergoing dialysis compared to controls. Furthermore, decrease in DMFT value was noted in CRF group despite of poor oral hygiene of the patient. We could also observe different oral manifestations in CRF group among which uremic fetor being the commonest. Conclusions: Our report suggest that saliva is noninvasive tool which act as an adjunct in diagnos­ing oral lesions and manifestations in CRF patients whose oral hygiene is often neglected with their reluctance in long term dental appointment in the middle of regular hemodialysis schedule.
