Use the following case description to complete the following exercises.
Mr.JEP is referred to a dental hygienist by the periodontist employer for Phase I therapy.He is 54 years old, in good health, and proud of his successful avoidance of both dentists and physicians for the last 30 years.A general dentist who saw Mr.JEP for an emergency, which turned out to be a periodontal abscess, referred him to the periodontist.Mr.JEP has no history of caries but has 3- to 4-mm probing depths throughout his mouth, 2 mm of recession on every tooth, and heavy subgingival deposits of calculus around all teeth.He vigorously brushes every day using fluoride toothpaste but no other oral hygiene aids.After Mr.JEP is introduced to a more thorough way to brush his teeth, he responds by saying, "Honey, I have been brushing my teeth longer than you have been alive."
-When Mr.JEP's response suggests that he is offended that the dental hygienist thinks he does not know how to brush his teeth,the best course of action for the dental hygienist would be to:

A) Tell him he is doing an ineffective job, and show him his plaque.
B) Tell him he should keep brushing the way he is but show him how to clean between his teeth.
C) Agree with him, and try to encourage him to improve the results of his brushing by, perhaps, using a new brush and cleaning around the gums more effectively.
D) Explain to him that the signs and symptoms of his periodontal disease will only get worse if he does not follow the dental hygienist's instructions.
