How Do Streptococcus Species Contribute to Dental Caries?
Members of the Viridans group, particularly Streptococcus mutans, play a crucial role in the development of dental caries. These bacteria adhere to the tooth surface, forming a biofilm known as dental plaque. They metabolize sugars to produce acid, which demineralizes the tooth enamel leading to caries. Histologically, carious lesions show demineralization of enamel and dentin, with bacterial colonization in the affected areas.
