Question 1

One can of snuff equals approximately what?&#10;A)Two packs of cigarettes&#10;B)Three packs of cigarettes&#10;C)Four packs of cigarettes&#10;D)Five packs of cigarettes

Accepted Answer

C)All smokeless tobacco contains tobacco-specific cancer-causing nitrosamines and nicotine added by the tobacco companies,which are "free" or available for absorption by the body in the presence of base chemicals.The higher the pH,the greater the available (approximately one can of snuff equals four packs of cigarettes)nicotine,and therefore the greater potential effect on the brain.

Question 2

Because smoking alters the body's ability to mount a host response,how does periodontal inflammation present itself in a smoker?&#10;A)Red,swollen gingival margins,with profuse bleeding&#10;B)Smooth tissue with minimal bleeding&#10;C)Smooth tissue with profuse bleeding&#10;D)Tight and firm margins with pyramidal papilla

Accepted Answer

B)Smoking alters the body's ability to mount a host response at both the local and systemic levels by changes in vasculature.These changes manifest as reduced bleeding upon probing,potentially causing misinterpretation of periodontal health,and reduction of oxygen in the periodontal pocket,which may alter subgingival flora.

Question 3

Smokers have greater probing depths,gingival recession,loss of attachment,and bone loss than non-smokers.Cigarette smoking is a potential contributing factor in necrotizing ulcerative gingivitis.&#10;A)Both statements are true.&#10;B)Both statements are false.&#10;C)First statement is true,second statement is false.&#10;D)First statement is false,second statement is true.

Accepted Answer

A)The number of cigarettes plus the number of years someone has been smoking is known as a dose response.Smokers have greater probing depths,gingival recession,loss of attachment,and bone loss.In addition,cigarette smoking contributes to necrotizing ulcerative gingivitis.

Question 4

Patients who smoke are more likely to present with what periodontal condition?&#10;A)Healthy tissue&#10;B)Gingivitis&#10;C)Early periodontal disease&#10;D)Moderate to advanced periodontal disease

Accepted Answer

D)Patients who smoke are more likely to present with moderate or advanced periodontitis but will often respond poorly to non-surgical periodontal therapy and periodontal re-care compared to non-smokers who have quit.

Question 5

What does smokeless tobacco diffuse through?&#10;A)Saliva&#10;B)Mucous membrane&#10;C)Tongue&#10;D)Salivary glands

Accepted Answer

B)Smokeless tobacco slowly diffuses through the mucous membrane and clears the system slowly,giving a more stable infusion of nicotine.

Question 6

Which are products that assist patients with nicotine withdrawal?&#10;A)Gum&#10;B)Patches&#10;C)Medications&#10;D)All of the above

Accepted Answer

D)The discussion and recommendation of an appropriate pharmacotherapy to help manage withdrawal symptoms for those who are nicotine-dependant is an important aspect of smoking cessation.Tobacco cessation medications are safe and effective,and have been shown to double the chances of a successful quit attempt.

Question 7

What are referred to as a &#34;poor man's&#34; cigarette and are small hand rolled cigarettes imported from India or Southeast Asia?&#10;A)Hookas&#10;B)Flavored cigarettes&#10;C)Kreteks&#10;D)Bidis

Accepted Answer

D)This hand-rolled "poor man's cigarette" is made from flakes and dust of dark tobacco leaves with vanilla,licorice,strawberry,cinnamon,or mango flavoring added to give a sweet taste and mask the strong tobacco smoke.

Question 8

Both bidis and kreteks deliver more nicotine,carbon monoxide,and tar than standard cigarettes.Users feel that water in the hookas "filters" out the toxins;hooka smoke has been shown to contain many of the same toxins found in cigarette smoke.

A)Both statements are true.
B)Both statements are false.
C)First statement is true,second statement is false.
D)First statement is false,second statement is true.

Accepted Answer

A)Both statements are true.Youth and young adults are trying alternative tobacco and herbal products believing that they are not as harmful as regular cigarettes.

Question 9

What are dental providers likely to see in the oral cavity of a smoker?&#10;A)Leukoplakia&#10;B)Leukoedema&#10;C)Linea alba&#10;D)Ectopic sebaceous glands

Accepted Answer

A)There is a dose response to smoking.The more a person smokes or uses any type of tobacco product,the more likely a form of leukoplakia will develop.Most leukoplakias,which are pre-malignant lesions,will resolve if smoking is discontinued.In an individual using smokeless tobacco this is referred to as "snuff dipper pouch."

Question 10

Second-hand smoke exposes the non-smoker to more chemicals than the smoker.How much worse are these chemicals?&#10;A)25 fold&#10;B)50 fold&#10;C)100 fold&#10;D)125 fold

Accepted Answer
