Cavity formation in a tooth, due to dental caries is due to______________?
Correct answer: C. Lateral spread of caries along DE junction and weakening of the outer covering enamel
- A. Destructive potential of streptococcus mutans
- B. Destructive potential of lactobacillus acidophilus
- C. Lateral spread of caries along DE junction and weakening of the outer covering enamel
- D. Mastectomy force and unrelated to the extent of carious process
Explanation
A visible cavity develops when caries spreads laterally along the dentinoenamel junction, undermining enamel until the weakened outer enamel collapses. Bacterial destruction initiates the lesion, but this undermining and collapse produces the cavity.
