Abstract
OBJECTIVE: The purpose of this study was to evaluate and to compare the cariogenic potential of different commonly consumed favored milk on caries development in rat's molar teeth. MATERIALS AND METHODS: Sixty Sprague-Dawley rats infected with an active growing culture of Streptococcus mutans were offered chocolate favored milk, strawberry favored milk, banana favored milk, plain milk, sweetened plain milk with 5% sucrose, and 10% sucrose ad libitum. RESULTS: Rats consuming favored milk developed significantly lower sulcal and smooth surface caries scores than rats consuming 10% sucrose. However, rats consuming plain milk developed significantly lower sulcal and smooth surface caries scores than animals consuming favored or sweetened plain milk except for chocolate favored milk. CONCLUSION: It was concluded that favored milk containing 5% sucrose showed a moderate cariogenic potential. CLINICAL SIGNIFICANCE: Although the overall results suggest that the cariogenic potential of favored milk is moderate and despite their nutritional value, occasional consumption of favored milk as a beverage might be accepted with caution. Parents, dental practitioners and other healthcare professionals should be aware of the cariogenicity of favored milk. They should keenly encourage the use of plain milk and discourage the use of any cariogenic drink which has a deleterious effect on teeth.
