Quizplus · Accepted Answer

1) Pit and fissure sealants can be applied to the chewing surfaces of the molars and premolars to protect them from decay.
2) Fluoride therapy can strengthen the tooth enamel and make it more resistant to decay.
4) Some orthodontic procedures, such as space maintainers, can prevent decay by correcting overcrowding and making it easier to properly clean the teeth.
While extraction of badly decayed teeth may be necessary in some instances, it is not considered a preventive procedure. Therefore, choice C is the best answer.

Preventive Procedures Include: 1) Pit and Fissure Sealants
