#MCQ 13: Which of the following is the best treatment plan to control rampant caries (many proximal caries that undermine enamel) ?

A. Restore all teeth with amalgam as soon as possible
B. Prescribe high fluoride tooth paste, give oral hygiene instruction, and wait until effectiveness has been appraised
C. Restore all teeth with crowns
D. Remove caries and place glass ionomer restorations then complete the treatment plan after the vitality of the teeth has been established

Answer: D. Remove caries and place glass ionomer restorations then complete the treatment plan after the vitality of the teeth has been established

Rampant caries control protocols suggest that caries should be removed and glass ionomer cement restorations should be placed until the true pulp status can be assessed.

Removing the caries allows the clinician to see if caries have extended to the pulp cavity.
Placing glass ionomer restorations allows for the affected dentin to be remineralized.
