Background. Early childhood caries (ECC) is associated with early colonisation and high levels of cariogenic microorganisms. With C. albicans being one of those, there is a need to determine the effectiveness of various chemotherapeutic agents against it. The study is aimed at isolating Candida species in children with ECC and at studying the antifungal effect of coconut oil, probiotics, Lactobacillus, and 0.2% chlorhexidine on C. albicans in comparison with ketoconazole. Materials and Methods. Samples were collected using sterile cotton swabs, swabbed on the tooth surfaces from children with ECC of 3 to 6 yrs and streaked on Sabouraud dextrose agar (HI Media) plates and incubated in a 5% CO2 enriched atmosphere at 37°C for 24 hours. Candida was isolated and its susceptibility to probiotics, chlorhexidine, ketoconazole, and coconut oil was determined using Disc Diffusion method. Results. The mean zone of inhibition for chlorhexidine was 21.8 mm, whereas for coconut oil it was 16.8 mm, for probiotics it was 13.5 mm, and for ketoconazole it was 22.3 mm. The difference between the groups was not statistically significant (Chi-square value 7.42, P value 0.06). Conclusion. Chlorhexidine and coconut oil have shown significant antifungal activity which is comparable with ketoconazole.

AIM: This study was carried out to estimate the concentrations three microelements in enamel of deciduous normal and carious teeth using atomic emission spectrometry. METHODS: A total of 80 deciduous molar teeth indicated for extraction  from children between the age group of 7-13 yrs. were taken for this study. The specimens were divided into four groups and the samples  were prepared using centrifuge flotation technique. They were analyzed for Manganese, Strontium and Zinc using inductively coupled plasma-atomic emission spectroscopy. RESULTS: This study shows that  sound enamel contains more of strontium when compared to the carious enamel. Carious enamel contains more of manganese, and zinc when compared to the normal enamel. Elements zinc and strontium occur in high concentrations, whereas elements manganese occur in low concentrations in enamel. The concentrations of elements  manganese, strontium and zinc does not vary in relation to sex of individual. CONCLUSION: The microelements strontium and zinc are present in high concentration. Further  studies are necessary to see their potential in mineralization and anticariogenic process.
