Résumé
This study was conducted to compare the caries preventive efficacy of Fluoritop - SR; the first fluoride varnish manufactured in India with Fluor Protector and Bifluorid 12, the two commercially available fluoride varnishes which have to be imported from other countries and are cost prohibitive. The demineralization inhibitory effects and the antibacterial effects on Streptococcus mutans were studied (in vitro). Calcium and Phosphorus dissolutions were estimated as a measure of the demineralization inhibitory effect. Antibiotic sensitivity tests using the serial tube dilution method and disk diffusion method were used to evaluate the antibacterial effects of the fluoride varnishes. Of the three varnishes, Fluor Protector was seen to exhibit the highest demineralization inhibitory effect, while Fluoritop-SR was found to be comparable to Bifluorid 12 in its caries protective effects.

Six cases of asymptomatic dental twinning anomalies in the primary dentition are reported in 4205 school children. A clinical and radiographic presentation of the cases of fusion of primary incisor teeth is illustrated. This clinical entity has been found to appear with varied clinical and radiographic appearances. An association of fusion of primary incisors with the number of succedaneous teeth was seen.
