Q: Case Study 1
Jill Carter is a 27-year-old female; she presents herself for a maintenance exam and prophylaxis. Her last recall visit was 6 months ago, and, at that time, the dentist prescribed a brush-on fluoride gel to control caries. Jill states, “I am upset by the stains on my teeth; I don't drink coffee or smoke.” She asked the RDH where this stain came from, what it is called, and how it will be removed. After carefully reviewing the medical history with Jill (she is not taking any medications) and a thorough examination, the RDH concludes she has staining.

Reference: Ref 21-1

- brown stain
- orange stain
- metallic stain
- tetracycline stain
A: brown stain
