Dental cavities are one of the most prevalent health problems worldwide, that 60% to 90 % of school children and nearly 100% of adults have dental cavities according to WHO. A recent study suggests that dead lactic acid bacteria prevent dental cavities by decreasing the number of plague bacteria. For further investigation, an experiment was conducted to observe the antibiotic effect of various types of lactic acid bacteria against cavity-causing oral bacteria. The result was applied to rabbit by feeding rabbit food covered with lactic acid bacteria, which showed a decrease of number of plague bacteria in the mouth.
