Question 2

Use the following case description to complete the following exercises.
Mrs.RWJ has been diagnosed with chronic periodontitis and has been referred to a dental hygienist for Phase I therapy.She is a widow, 63 years of age, in good health, and is living on her social security benefits.Mrs.RWJ has some arthritis in her hands and feet, particularly affecting her fingers and toes.She has 28 teeth; only her third molars are missing.Her clinical findings include 2- to 4-mm probing depths around all of her teeth, with 1 mm of recession throughout.All of the deeper 4-mm probe depths are on the interproximal surfaces of the maxillary molars.Mrs.RWJ brushes her teeth twice each day, has moderate amounts of plaque on all gingival and interproximal surfaces, and has moderate subgingival calculus throughout the mouth.She has little supragingival calculus.Mrs.RWJ has a history of caries, evidenced by numerous fillings and two crowns.She also has two carious lesions that will be treated by her general dentist after Phase I therapy is complete.Her periodontal prognosis is good, and the periodontist does not expect to perform periodontal surgery after the dental hygienist has completed the treatment.

Question 4

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:

Accepted Answer

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.

Question 5

Scrub technique

Accepted Answer

A)  Bristles are directed apically at a 45-degree angle to the long axis of the tooth, using short vibratory strokes.The focus of this technique is on sulcular cleaning.
B)  Bristles are directed coronally at a 45-degree angle to the long axis of the tooth.Bristles are repeatedly pressed against the gingival margin and then lifted away.The focus of this technique is to massage the tissue and to increase blood flow.
C)  This technique is the simplest.Bristles are placed on the teeth and moved back and forth.This technique does not focus on cleaning the gingival margin.
D)  Bristles are directed apically but not at a right angle to the gingival.Pressure is applied to flex the bristles and blanch the tissues.The focus of this technique is to increased blood flow through gingival stimulation and to use salt water and sodium bicarbonate solutions.

Question 6

The daily plaque biofilm control program is the responsibility of the:

Accepted Answer

A)   Patient
B)   Dentist
C)   Dental hygienist
D)   Dental assistant

Question 7

Stillman technique

Accepted Answer

A)  Bristles are directed apically at a 45-degree angle to the long axis of the tooth, using short vibratory strokes.The focus of this technique is on sulcular cleaning.
B)  Bristles are directed coronally at a 45-degree angle to the long axis of the tooth.Bristles are repeatedly pressed against the gingival margin and then lifted away.The focus of this technique is to massage the tissue and to increase blood flow.
