Quizplus · Accepted Answer

Mutans streptococci and Lactobacillus acidophilus are the two most important bacteria in causing dental caries. Streptococcus mutans is responsible for initiating the caries process by producing acids from sucrose fermentation, while Lactobacillus acidophilus is responsible for acidogenesis and acid tolerance. Other bacteria, such as Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans, are associated with periodontal disease but not with dental caries. Staphylococcus aureus is not typically associated with either dental caries or periodontal disease.
