Background and Objectives: Early childhood caries (ECC) is the most common chronic disease of childhood in many developing countries, which is associated with local, systemic, psychological, and social consequences. Multiple variables are shown to be associated with an increased risk of ECC. The knowledge regarding the role of saliva in the pathophysiological process of ECC still remains controversial and unexplored. Scanty studies focused on probing the role of salivary flow rate, pH, buffering capacity, and secretory immunoglobulin A (sIgA) in unstimulated whole saliva of children with ECC and children without ECC., Aim: To assess the salivary flow rate, pH, buffering capacity, and sIgA levels in children with ECC and caries-free children and to evaluate their role in caries risk assessment.Materials and Methods: The study was carried out among 64 children aged between 24 and 71 months. Clinical examinations were carried out according to the criteria by the World Health Organization, and carious status was recorded. Subjects were categorized as group I with ECC (dmfs-Decayed, Missing or Filled Surfaces (Deciduous dentition) of ≥5), and group II included children without ECC (dmfs = 0). Unstimulated whole salivary samples were collected in a sterile vial and stored at -70°C by draining. Estimations of salivary flow rate, pH, buffering capacity, and sIgA levels were done. Digital pH meters were used for the estimation of pH and buffering capacity. A human IgA enzyme-linked immunosorbent assay (ELISA) kit was used to estimate sIgA levels. Statistical software IBM Statistical Package for the Social Sciences (SPSS) statistics 20.0 (IBM Corporation, Armonk, New York, United States of America) was used to analyze the data., Results: The mean salivary flow rate decreased in group I children with ECC (0.15 ± 0.05) when compared to group II children without ECC (0.67 ± 0.14), which was statistically significant. In caries active children, no statistically significant correlation was found between salivary flow rate and the dmfs scores [ r -value (-0.247)] and p -value (0.147). The mean level of salivary pH is decreased in group I children with ECC (4.65 ± 0.4) when compared to group II children without ECC (7.28 ± 0.18). In the caries active group, the levels of salivary pH decrease as the dmfs scores increase, and this correlation is found to be statistically significant ( r -value of 0.547 and p -value of 0.002). The mean level of buffering capacity is decreased for caries-active children (5.45 ± 0.49) when compared to caries-free children (8.94 ± 0.42). In caries active children, as the dmfs scores increase, the salivary buffering capacity decreases, and this correlation is found to be not statistically significant ( r -value of -0.334 and p -value of 0.161). The mean levels of sIgA in group I children with ECC were higher (10.61 ± 0.90) than that in group II children without ECC (6.11 ± 1.22). In the caries-active group, the salivary sIgA levels were comparatively higher than in the caries-free children. As the dmfs scores increase, the level of the sIgA increases in caries-active children, and this correlation is noted to be highly statistically significant ( r -value of 0.769 and p -value 0.008)., Conclusion: Children with ECC showed decreased salivary flow rate, pH, buffering capacity, and increased sIgA levels, while children without ECC showed increased salivary flow rate, pH, buffering capacity, and decreased sIgA levels. The salivary parameters, such as salivary flow rate and buffering capacity, showed no correlation with the dmfs score, while salivary pH and sIgA levels have a positive correlation in caries-active children., How to Cite This Article: Sivakumar A, Narayanan R.

Background: Saliva is one of the most important aids in the diagnosis of various oral diseases. Few physicochemical properties of saliva such as flow rate, pH, and buffering capacity often vary with the occurrence of dental caries, fluorosis, and other systemic conditions., Purpose: The aim of the study was to evaluate the relationship between the salivary flow rate, pH, and buffering capacity in healthy children, children with caries, children with fluorosis, and children with both caries + fluorosis., Materials and Methods: The study population consisted of 144 children aged 7-14 years and were divided into four groups of 36 children each. Group I, 36 healthy children with no caries and fluorosis; group II, 36 children with caries (dmfs ≤ 10); group III, 36 children with fluorosis (moderate to severe); and group IV, 36 children with caries + fluorosis. Unstimulated saliva is collected from all the selected subjects and evaluated for the salivary flow rate, pH, and buffering capacity. The recorded data were tabulated and statistically analyzed using a paired t -test., Results: The mean salivary flow rate and buffering capacity were found to be highest in group III when compared with all the other groups. The mean pH was greater in group I when compared with groups I, II, and III., Conclusion: The physicochemical properties of saliva like pH, buffering capacity, and salivary flow rate alter with caries and fluorosis conditions. Hence, more clinical and laboratory studies are needed to determine the exact relationship between these physicochemical properties of saliva in dental caries and fluorosis., How to Cite This Article: E RR, S S, M K, et al.

Introduction: Dental caries is a preventable disease that can be prevented by suppressing any one of the factors of the Keyes triad., Aim and Objective: To investigate the effect of probiotic yogurt on salivary pH, calcium level, and buffering capacity., Materials and Methods: A total of 60 children were randomly selected and were divided into 2 groups. The test group consumed 200 mL of probiotic yogurt and the control group consumed 200 mL of regular curd everyday for 30 days. A base-line nonstimulated salivary sample (2 mL) was collected. The salivary pH, buffering capacity, and calcium level was assessed at baseline, after 15 and 30 days. The data were statistically analyzed., Result: The mean pH levels of the probiotic group were 7.03 and salivary buffering capacity was found to be 2.000. Salivary calcium levels increased with the use of probiotic yogurt at the end of 30 days (mean of 4.79) compared to the control group., Conclusion: Consumption of probiotic yogurt for a short period of time can prevent dental caries by increasing salivary calcium level., How to Cite This Article: Malavalli PL, Shetty SB, Thimmaiah C, et al.

Context: The implication of severe dental caries in children may have its effect on general health apart from affecting the orodental tissues. Many children reporting with severe caries have shown weighing less due to malnourishment resulting in anemia and modified somatic growth., Aims: Study aimed to assess and compare anthropometric measurements, hemoglobin level, and salivary parameters among caries-free and severe early childhood caries (E-CCC) children., Settings and Design: For caries-free group [Group I] and S-ECC group [Group II] data were obtained from age-matched children with similar socioeconomic status., Materials and Methods: Children with severe caries and without caries from the age-group 3 - 6 years participated in the study. Children were measured for height, weight, measurement of mid-upper arm circumference, and waist circumference. Hemoglobin level was recorded. The collected unstimulated saliva was assessed for flow rate, salivary pH, and its buffering capacity., Statistical Analysis Used: Both descriptive and inferential statistical analyses were carried out using Windows software and SPSS (21). Tests of significance namely t-test and Chi-square test were used along with regression analysis., Results: Caries experience showed no statistical difference for age and gender among the sample population. Significant difference was found for all anthropometric measurements. When comparison for hemoglobin was done for both groups I and II, significant difference was observed [ p = 0.003]., Conclusion: Children with severe dental caries in the present study had low hemoglobin which, if persisted, can lead to anemia. Though the anthropometric parameters may appear normal in children diagnosed with severe early childhood caries, pediatric dentist should ensure the hemoglobin level test, as iron deficiency can affect growth and development of the child, if left undiagnosed., How to Cite This Article: Deshpande AN, Sudani U, Wadhwa M, et al.

Background: The diagnostic utility of saliva is currently being explored in various branches of dentistry, remarkably in the field of caries research. This study was aimed to determine if assessment of salivary pH and buffering capacity would serve as reliable tools in risk prediction of early childhood caries (ECC)., Materials and Methods: Paraffin-stimulated salivary samples were collected from 50 children with ECC (group I) and 50 caries free children (group II). Salivary pH and buffering capacity (by titration with 0.1 N hydrochloric acid) were assessed using a handheld digital pH meter in both groups. The data obtained were subjected to statistical analysis., Results: Statistically, no significant difference was observed between both the groups for all salivary parameters assessed, except for the buffering capacity level at 150 μl titration of 0.1 N hydrochloric acid (p = 0.73; significant at 1% level)., Conclusion: Salivary pH and buffering capacity may not serve as reliable markers for risk prediction of ECC.

Background and Objectives: The purpose of this study was to evaluate the relationship between the physicochemical properties of saliva such as flow rate, pH, buffering capacity, calcium level, total protein and total antioxidant levels in caries free and caries active children., Materials and Methods: The present study included one hundred and twenty healthy children who were divided into two groups and subdivided according to gender. They were further divided into caries free and caries active children with 15 children in each group. Unstimulated saliva was collected by suction method and flow rates were determined. The samples were then analyzed for pH, buffering capacity, total protein, calcium and total antioxidant levels. The data was then statistically analyzed using student's 't' test {unpaired}., Results: The results revealed that when all these parameters were compared among the caries free and caries active children, the flow rate, pH and buffering capacity were slightly reduced in caries active children, but the total protein and total antioxidant capacity of saliva increased significantly in caries active children and the total calcium decreased significantly in caries active children., Conclusion: Within the limitation of this study, we can conclude that, the physicochemical properties of saliva play a major role in the development of caries.
