A four-year-old girl is at a high risk for caries because of poor nutrition and oral hygiene habits. This girl would benefit greatly by having a fluoride varnish placed to improve her teeth's defenses against cavities, but she is not cooperating so as to allow the varnish to be placed on all tooth surfaces.
What area should be given priority for placing the varnish?
  1. All posterior occlusal surfaces
  2. Maxillary anterior teeth
  3. Mandibular posterior teeth
  4. Mandibular anterior teeth
Explanation
Answer: B - The maxillary anterior teeth should be given priority for placing the varnish.
Lack of patient cooperation in this instance makes placing the varnish on the easily accessible top front teeth much easier than on most other areas. More importantly, this patient's risk for developing early childhood caries (ECC) is very high. The maxillary anterior teeth frequently are the first to suffer from caries due to frequent intake of sugary drinks.
