Question 1

Positive,long-term effects of periodontal therapy are reliably received with:

Accepted Answer

Positive, long-term effects of periodontal therapy can only be achieved with a combination of patient compliance, effective patient plaque biofilm control, and effective dental hygiene treatment and care. Without any one of these components, the effects of periodontal therapy will not be as lasting or beneficial.

Question 2

At the re-evaluation appointment,the patient had no supragingival plaque biofilm.One area on the mesial of tooth #19 bled when the surface was probed.All other areas had no bleeding.The first thing that should be done is to:

Accepted Answer

The presence of bleeding on probing indicates that there is some inflammation in the area, which may be due to the accumulation of subgingival plaque biofilm. Rescaling the area will remove any plaque biofilm that may be present and help to reduce the inflammation. The other options, such as subgingival irrigation, local or systemic antibiotic therapy, or antiseptic therapy, may be considered if the bleeding persists despite rescaling or if there are other signs of active periodontal disease, such as pockets or bone loss.

Question 3

Instrumentation of the crowns and root surfaces of the teeth to remove supragingival plaque biofilm,calculus,and stains from these surfaces is called:

Accepted Answer

Hand-scaling instrumentation and powered-scaling instrumentation are both used to remove supragingival plaque biofilm, calculus, and stains from the crowns and root surfaces of teeth. While root planing is typically used for subgingival cleaning, and gingival curettage is a surgical procedure, polishing is used to smooth the surfaces after instrumentation and is not used to remove deposits. Therefore, the best choice(s) for removing supragingival deposits is A and B.

Question 4

What procedure incorporates the removal of plaque biofilm,plaque retentive features,and calculus above and below gingival margins?

Accepted Answer

Root planing is a procedure that incorporates the removal of plaque biofilm, plaque retentive features, and calculus above and below the gingival margins. Hand-scaling and powered-scaling instrumentation, gingival curettage, and polishing may help to remove some of the plaque and calculus, but they do not address all the factors involved in root planing.

Question 5

The difference between root planing and scaling is instrumenting every portion of a root surface,not only the identifiable calculus deposits.

Accepted Answer

The difference between root planing and scaling is instrumenting every portion of a root surface,not only the identifiable calculus deposits as in scaling alone.

Question 6

One month after completing nonsurgical periodontal therapy,the patient returns for a re-evaluation.The procedures performed at that time include:

Accepted Answer

Probing and plaque biofilm control reinforcement are necessary to assess whether the nonsurgical periodontal therapy was successful in reducing inflammation and restoring periodontal health. Irrigation may be beneficial but is not typically performed at this re-evaluation appointment.

Question 7

The removal of the surface layer of cementum or dentin that may be impregnated with bacterial endotoxin or calculus to create a glassy,hard surface is the goal of:

Accepted Answer

Root planing is the process of removing the surface layer of cementum or dentin that may be contaminated with bacterial endotoxin or calculus to create a smooth, hard surface. Hand-scaling and powered-scaling instrumentation are used to remove calculus, but they do not necessarily remove the contaminated surface layer. Gingival curettage involves the removal of diseased tissue from the gum line, which is not the same as root planing. Polishing is used to smooth teeth after scaling or root planing, but does not remove the surface layer in question. Therefore, C is the best choice for the described scenario.

Question 8

Positive long-term effects of periodontal therapy are reliably achieved with patient compliance,effective plaque biofilm control,and dental hygiene treatment.

Accepted Answer

l therapy are reliably achieved with patient compliance,effective plaque biofilm control,and dental hygiene treatment.

Question 9

The goal of root planing is leaving the roots clean,making them easier to maintain,and making them less likely to be associated with periodontal disease.

Accepted Answer

The goal of root planing is leaving the roots clean,that is,free of calculus and plaque biofilm.

Question 10

The term nonsurgical periodontal therapy is used synonymously with periodontal débridement and the traditional terms of scaling and root planing.

Accepted Answer

Nonsurgical periodontal débridement,periodontal débridement,and scaling and root planing are all used synonymously to describe these periodontal procedures.

Question 11

The key to long-term successful nonsurgical periodontal therapy is patient plaque biofilm control.

Accepted Answer

The key to long-term successful nonsurgical periodontal therapy is patient plaque biofilm control.

Question 12

The terms prophylaxis,oral prophylaxis,dental prophylaxis,and prophy all describe a preventive procedure to remove local irritants to the gingiva,including complete calculus removal,followed by root planing.

Accepted Answer

The terms prophylaxis,oral prophylaxis,dental prophylaxis,and prophy are all used synonymously for describing a preventive procedure to remove local irritants to the gingiva,including complete calculus removal,followed by root planing.

Question 13

The procedure focusing on the entire root surface associated with the periodontal pocket is:

Accepted Answer

Root planing is the procedure that focuses on the entire root surface associated with the periodontal pocket, and it involves removing the plaque, calculus, and infected tissue from the root surface. Hand-scaling and powered-scaling instrumentation only remove plaque and calculus from the visible parts of the teeth, while gingival curettage is a procedure that removes inflamed tissue and is not routinely performed. Polishing, although beneficial for removing surface stains, does not address the underlying issue of periodontal disease.

Question 14

The polishing procedure is commonly referred to as a prophylaxis or prophy.

Accepted Answer

Using the term prophylaxis or prophy,as applied to the polishing procedure,is inaccurate.Polishing may have an esthetic value,but it has no therapeutic value.Prophylaxis is a preventive procedure designed to remove local irritants to the gingiva,including complete calculus removal,followed by root planing.

Question 15

What term describes the preventive procedure used for removing local irritants to the gingiva?

Accepted Answer

Prophylaxis is a preventive procedure that involves removing local irritants to the gingiva, including plaque and calculus, through scaling, polishing, and fluoride treatment. It is commonly known as a dental cleaning and is recommended every six months for maintaining good oral health.

Question 16

Root planing is thought to render root surfaces less prone to the reestablishment of bacterial plaque biofilm.

Accepted Answer

It has not been proven that root planing in combination with scaling renders root surfaces less prone to the reestablishment of bacterial plaque biofilms.

Question 17

The term nonsurgical therapy is appropriately named because sharp blades are used during treatment to cut tissues,which is a form of surgery.

Accepted Answer

In periodontology,the term surgery is reserved for more invasive,cutting procedures.

Question 18

The use of agents for removing stains and supragingival plaque biofilm from the teeth is called:

Accepted Answer

Polishing is the procedure that involves the use of agents to remove stains and supragingival plaque biofilm from the teeth.

Question 19

The treatment procedure designed to remove cementum or surface dentin that is rough,impregnated with calculus,or contaminated with toxins or microorganisms is called:

Accepted Answer

The procedure of removing cementum or rough surface dentin impregnated with calculus or contaminated with toxins or microorganisms is called root planing. Therefore, option C is the correct answer. Hand-scaling instrumentation and powered-scaling instrumentation refer to the methods of removing calculi from the tooth surface, whereas gingival curettage is the removal of the soft tissue lining the pocket. Polishing refers to the smoothing of the tooth surface after scaling and root planing.

Question 20

The removal of identifiable deposits of calculus and supragingival plaque biofilm is achieved with:

Accepted Answer

The removal of identifiable deposits of calculus and supragingival plaque biofilm can be achieved with both hand-scaling instrumentation and powered-scaling instrumentation. Therefore, choice F (A and B) is the best answer. Root planing and gingival curettage are indicated for removal of subgingival calculus and plaque biofilm, while polishing removes residual stains and roughness on the tooth surface.
