Caries, all are true except______________?
Correct answer: C. Lactobacillus is main acusative organism in plaque
- A. Pit and Fissure caries can be prevented by using pit and tissue sealants
- B. Smooth surface caries occur due to streptococcus mutans
- C. Lactobacillus is main acusative organism in plaque
- D. Fluorides help in reducing caries incidence
Explanation
Lactobacilli are important in the progression of established caries but are not the main initiating organisms in plaque; mutans streptococci are more strongly associated with initiation. Pit-and-fissure sealants and fluoride reduce caries risk, while sucrose-fermenting streptococci contribute to smooth-surface caries.
