Q: Case Study 1
You have been hired as a dental hygienist at the Health Department dental clinic in your county. The patient population in this facility is predominately low income. There is no community water fluoridation in the area. Most of your patients do not follow a healthy lifestyle through diet and exercise.

Reference: Ref 26-1

Open and read the attached case to answer the following question. You have been asked by your employer to develop a caries management strategy that covers all of the patients' needs. Which of the following is not an objective for this caries management strategy?
- Determine restorative treatment needs
- Define steps for remineralization program
- Determine areas that require remineralization
- Determine the patients' financial situation
A: Determine the patients' financial situation

Q: Case Study 1
You have been hired as a dental hygienist at the Health Department dental clinic in your county. The patient population in this facility is predominately low income. There is no community water fluoridation in the area. Most of your patients do not follow a healthy lifestyle through diet and exercise.

Reference: Ref 26-1

Open and read the attached case to answer the following question. Your employer has decided to send the caries risk “Oral Health Check Sheet” to his patients and ask that they fill it out and bring it to their next appointment. This checkoff sheet lists 10 questions associated with a patient's caries risk. Is this a good choice by your employer and why?
- No. Most patients will learn very little about their problem if merely given a checklist to fill out
- Yes. This will be convenient for patients to complete at home and bring in
- No. The form may get lost in the mail
- Yes. This will save the dental hygienist time wasted talking to the patient
- No. This will cost the dentist too much money in stamps
A: Yes. This will be convenient for patients to complete at home and bring in

Open and read the attached case to answer the following question. When a patient presents with no dental caries, which of the following treatment options would not be recommended?
- Provide the patient with positive care and education so that dental health will be maintained
- Review the factors with the patient that put him or her in the “low risk” category
- Be glad that the patient is caries free and leave well enough alone
- Evaluate and supervise plaque control measures at routine maintenance appointments
A: Be glad that the patient is caries free and leave well enough alone
