Aim: To evaluate and compare the sorption and solubility of three modified glass ionomer cements –Glass Hybrid Restorative System (Equiaforte), Zirconomer Improved and resin modified glass ionomer cement (RMGIC) in artificial saliva. Materials And Methods: A total of 45cylindrical specimens (4mm diameter and 6mm height) were prepared for each material following the manufacturer’s instructions. After subjecting the specimens to thermocycling of 500 cycles between 5 and 55 degree Celsius with the dwell time 15secs,45 specimens evaluated for sorption and solubility, first weighing them by a precision weighing scale (W1), then immersing them in artificial saliva for 28days and weighing them(W2), and finally dehydratingin an oven for 24 hours and weighing them(W3). Since the obtained values show normal distribution differences between the groups data were analyzed using the one way analysis of variance (ANOVA). For pairwise evaluation between the groups post hoc dunnet t3 test was used. Results: The sorption and solubility values in artificial saliva were minimum for zirconomer improved glass ionomer cement with the mean value of sorption 52.91 ± 1.73 µg/mm3 and solubility 10.47 ± 1.52 µg/mm3 when compared with other groups.The difference between groups was found to be statistically significant (p<0.05) in terms of sorption and solubility.

A BSTRACT Aim and Objective: The aim of the study was to assess the efficacy of probiotic and green tea mouthrinse on salivary pH. Materials and Methods: This study was conducted over a period of 1 month among 40 healthy schoolchildren aged between 6 and 8 years. The subjects who fulfilled inclusion criteria were selected and randomly divided into two groups, namely probiotic and green tea groups. Salivary pH was recorded at baseline (0 day) and at the end of the specified time using GC pH strips. Statistical analysis was done using paired t test. P < 0.05 was considered statistically significant. Result: The comparison of mean pH scores for green tea showed that the pH of saliva was increased in the children after rinsing with green tea (6.00–7.60) and was statistically significant ( P < 0.001). Similarly, when pre- and post-mean pH was compared in the probiotic group, the pH was found to be higher in the probiotic rinse group (5.60–7.20). The results were statistically significant. Conclusion: The study conducted shows the beneficial effects of green tea in providing a alkaline environment, which is conducive to the oral health of children.

Background: Pituitary gland dysfunction might be predicted by examining the alteration of Sella turcica during the routine radiological examination of lateral cephalogram. Aim: The study aimed to analyze the variation in size and shape of sella turcica according to age and gender on lateral cephalogram among the people in the south zone of Chennai city. Materials and Method: A series of lateral cephalogram images from 200 patients comprising 94 males and 106 females were collected retrospectively from archives in the database. The shape and size of sella turcica were measured digitally. Statistical analysis was done using the Chi-square test and unpaired sample t-test. Results: The frequency of distribution of shapes of sella turcica among the people in Chennai city was 46% normal followed by 15.5% irregular dorsum sellae, 14.5% pyramidal shape, 11.5% bridging, 7% oblique anterior wall, 5.5% double contour. The length and depth of Sella turcica was greater in males when compared with that of the females which were statistically significant (P < 0.01). The depth and diameter were higher in the 10–20 years age group than the 20–30 year age group, which was statistically significant (P = 0.01). Conclusion: The size of Sella turcica alters between different age groups and gender. Variations in the shape of Sella turcica were present in nearly half of the individuals in the present study. Thus, the morphology of Sella turcica should be assessed as a part of routine radiographic examination.

Background: Dental caries continue to be one among the major problems related to oral health in developing countries, that affects 60%–90% of school-aged children and adults. According to the WHO Global oral data bank in 2009 the point prevalence was 54% among 12 years old. Studies on prevalence conducted in Dakshina Kannada district reported a caries prevalence ranging from 32.8% to 82.6%. This study was undertaken to assess the risk of among school-going young adolescents using the Cariogram model. Subject and Methods: A cross-sectional descriptive epidemiological study was conducted among school-going young adolescents of Sullia taluk Dakshina Kannada for a period of 3 months (August–October) 2019. From a total of 20 schools, 3 schools were randomly selected and children satisfying inclusion/exclusion criteria were randomly drawn from these schools. Data on parameters of Cariogram model were collected on a specially designed pro forma consisting of four parts, namely Questionnaire, along with a clinical examination, the collection of saliva and microbiological analysis. Descriptive data were recorded and Fischer's Exact test was used to test the significance of the findings. P ≤ 0.05. Results: An analysis of the relative contribution of each cariogram parameter in relation to the caries experience revealed that diet content, frequency of diet, mutans count were statistically significant factors in determining caries risk (P < 0.05). Conclusion: In conclusion, the present study performed with cariogram in young adolescent school-going children revealed that diet content, frequency of diet, mutans count were statistically significant factors in determining caries risk and susceptibility factors were mainly responsible for the aforementioned experience of the school children.
