Question 1

Periodontal debridement and scaling and root planing may include all of the following items EXCEPT one.Which one is the EXCEPTION?&#10;A) Hand scalers&#10;B) Powered scalers&#10;C) Lasers&#10;D) Locally delivered antimicrobials&#10;E) High-speed hand pieces

Accepted Answer

High-speed hand pieces are not typically used in periodontal debridement or scaling and root planing procedures.

Question 2

Match the periodontal surgery to the indicated condition.&#10;Removal of supporting bone&#10;A)Gingivectomy&#10;B)Modified Widman flap&#10;C)Osteotomy&#10;D)Osteoplasty&#10;E)Repositioned flap

Accepted Answer

Osteotomy involves removal of bone to reshape or reposition the jawbone.

Answer: D 
 Osteoplasty involves reshaping or contouring the jawbone, without any bone removal.

The other options are not associated with removal of supporting bone:

A) Gingivectomy involves the removal of excess gum tissue.

B) Modified Widman flap is a periodontal procedure where the gum tissue is lifted and deep cleaning is done to remove bacteria and infected tissue.

E) Repositioned flap refers to repositioning of the gum tissue without any bone removal.

Question 3

A combination of scaling and root planing (SRP)and locally delivered antimicrobials should be considered if nonsurgical therapy is the treatment of choice.A meta-analysis indicates an overall significant reduction in pocket depth with adjunctive local antimicrobials versus SRP alone.

A) Both statements are true.
B) Both statements are false.
C) The first statement is true; the second is false.
D) The first statement is false; the second is true.

Both statements are true.

Accepted Answer

Both statements are true. The combination of scaling and root planing (SRP) with locally delivered antimicrobials is often considered when nonsurgical therapy is chosen for periodontal treatment. This approach has been supported by meta-analyses showing a significant reduction in pocket depth when local antimicrobials are used adjunctively with SRP compared to SRP alone.

Question 4

Each of the following items is included in the creation of a treatment plan for periodontal therapy EXCEPT one.Which one is the EXCEPTION?&#10;A) Patient age&#10;B) Risk assessment&#10;C) Disease prognosis&#10;D) Periodontal examination

Accepted Answer

Patient age is not commonly considered a factor in determining the appropriate treatment plan for periodontal therapy. However, the patient's overall health and medical history should be considered. The other options listed (risk assessment, disease prognosis, and periodontal examination) are all important components of developing a treatment plan for periodontal therapy.

Question 5

Each of the following outcomes can be expected after nonsurgical periodontal therapy EXCEPT one.Which one is the EXCEPTION?&#10;A) Healing of long junctional epithelium&#10;B) Regeneration of alveolar bone&#10;C) Gingival recession&#10;D) Repopulation of younger,less pathogenic bacteria

Accepted Answer

Nonsurgical periodontal therapy typically results in healing through the formation of a long junctional epithelium rather than regeneration of alveolar bone.

Question 6

Match the periodontal surgery to the indicated condition.&#10;Removal of nonsupporting bone&#10;A)Gingivectomy&#10;B)Modified Widman flap&#10;C)Osteotomy&#10;D)Osteoplasty&#10;E)Repositioned flap

Accepted Answer

Osteoplasty involves the removal of nonsupporting bone to reshape the alveolar process without removing any tooth-supporting bone.

Question 7

Scaling and root planing (SRP)is a type of nonsurgical periodontal therapy.SRP reduces gingival inflammation and probe depths,leading to increased clinical attachment level.&#10;A) Both statements are true.&#10;B) Both statements are false.&#10;C) The first statement is true; the second is false.&#10;D) The first statement is false; the second is true.

Accepted Answer

Scaling and root planing (SRP) is indeed a type of nonsurgical periodontal therapy that can reduce gingival inflammation and probe depths, ultimately leading to increased clinical attachment level.

Question 8

Match the periodontal surgery to the indicated condition.&#10;Gingival hyperplasia&#10;A)Gingivectomy&#10;B)Modified Widman flap&#10;C)Osteotomy&#10;D)Osteoplasty&#10;E)Repositioned flap

Accepted Answer

Gingivectomy is the surgical removal of excess gum tissue and is an appropriate treatment for gingival hyperplasia.

Answer: B
 Modified Widman flap is a surgical procedure used to treat periodontitis, an inflammatory condition of the gums and bones that support teeth. It involves the removal of diseased gum tissue and bone, followed by the repositioning of the remaining healthy tissue.

Answer: D
 Osteoplasty is a surgical procedure used to reshape or smooth the bone around a tooth or teeth, which can be done to correct periodontal defects caused by bone loss due to disease or trauma.

Answer: E
 Repositioned flap surgery is a procedure in which the gum tissue is lifted from the underlying bone, repositioned to cover areas of exposed tooth roots or bone defects, and then sutured in place. This can be used to treat conditions such as gingival recession. Osteotomy, which involves cutting the bone, would not be appropriate for gingival hyperplasia.

Question 9

Order the periodontal bacteria from first to last as to how they repopulate in a pocket.&#10;A) Streptococcus,Veillonella,Capnocytophaga&#10;B) Bacteriodes,Capnocytophaga,Prevotella&#10;C) Bacteriodes,Capnocytophaga,Veillonella&#10;D) Streptococcus,Spirochetes,Veillonella

Accepted Answer

The sequence of bacterial repopulation in a periodontal pocket starts with early colonizers such as Streptococcus, followed by intermediate colonizers like Veillonella, and then later colonizers such as Capnocytophaga. This sequence reflects the ecological succession in the development of dental plaque.

Question 10

Each of the following is a goal of nonsurgical periodontal therapy EXCEPT one.Which one is the EXCEPTION?&#10;A) Preserve natural dentition.&#10;B) Maintain periodontium.&#10;C) Reestablish tissue health.&#10;D) Regenerate alveolar bone.

Accepted Answer

Nonsurgical periodontal therapy focuses on preserving natural dentition, maintaining periodontium, and reestablishing tissue health. However, it does not aim to regenerate alveolar bone. This may require surgical intervention or regenerative techniques.

Question 11

Match the periodontal surgery to the indicated condition.&#10;Guided tissue regeneration&#10;A)Gingivectomy&#10;B)Modified Widman flap&#10;C)Osteotomy&#10;D)Osteoplasty&#10;E)Repositioned flap
