[2025-10-02T06:02:44.920526] [PI reasoning] **Analyzing dental caries bacteria**

I need to answer the MCQ about which bacteria are responsible for the progression of dental caries. The options are Actinomyces, proteolytic bacteria, acidogenic bacteria, and gram-positive bacteria. I recall that Streptococcus mutans initiates caries, while lactobacillus is key in progression. The term "acidogenic" relates to those producing acid, which includes both Streptococcus and Lactobacillus. Actinomyces links to root caries but is less about progression. So, I’ll choose acidogenic bacteria as the best answer. Let’s gather some quick citations.
