Aim The aim of the present study was to evaluate the anticar-iogenic efficacy of hot and cold aqueous extracts of Terminalia chebula against Streptococcus mutans as an oral rinse and also to discover the acceptability of the mouthwash in children. Settings and design Sixty children between 8 and 12 years with high caries risk were selected. Materials and methods 10% concentration of hot and cold aqueous extracts were prepared. Children were randomly divided into extract and control group. Baseline salivary samples were taken, and the samples were re-collected at 10, 60, and 90 minutes interval after rinsing. Microbial and pH analysis were done. An acceptability questionnaire was filled. Statistical analysis Tukey's multiple comparison test. Results The results show statistically significant difference in S. mutans counts at 10, 60, and 90 minutes interval when compared with negative control. However, when the hot and cold extracts were compared, there was no significant difference. Acceptability questionnaire showed 65 to 75% overall acceptability for both types of extract. Conclusion Results of this study showed that both types of aqueous extract of T. chebula may be used as potential anticariogenic mouthwash with acceptable taste in children.

Background: Oral habits and caries if left untreated may result in crowding and arch length discrepancy in developing dentition. Therefore, appliances are used to maintain the arch length and for proper relationship between dental arches. However, its insertion may cause an increase in bacterial concentration. Aim: This study aimed to evaluate the growth of Streptococcus mutans, Lactobacillus sp., and Candida albicans in saliva during the first 6 months of orthodontic therapy. Materials and Methods: Twenty children in the age group of 6-15 years were selected with regard to indication of orthodontic treatment, and subsequently grouped as patients to be treated with fixed space maintainers or removable appliances. Unstimulated saliva was collected in a sterile container at baseline and at 1-month, 3-month, and 6-month recalls for every selected child. Samples collected were processed for bacterial culture in different culture media at different time intervals. Statistical Analysis: SPSS (Statistical Package for Social Sciences) Version 15.0 statistical software was carried for bacterial counts. Chi-square test and t-test were performed to know the effects of each variable and to reveal the statistical significance. Result: Bacterial counts of Streptococcus mutans, Lactobacillus sp., and Candida albicans were found to be statistically significant (P 0≤ 0.001), (P < 0.05), and (P < 0.001), respectively in both the groups at all intervals. Conclusion: At different time intervals, the total numbers of bacterial count of Streptococcus mutans were comparatively higher, followed by Lactobacillus sp. and Candida albicans.

Mixed dentition space analysis plays an important role in the diagnosis of tooth size arch length discrepancies. A large number of cases of malocclusion start during the mixed dentition stage. Earlier treatment reflects better comprehension of malocclusions.
