PERIO QUIZ

Which of the following is not a key category in the 2017 classification of periodontal and peri-implant diseases and conditions?

• Periodontal health and gingival diseases

• Periodontitis

• Dental caries and enamel hypoplasia

• Peri-implant diseases and conditions

Answer explanation

The 2017 classification focuses on periodontal health, periodontitis, and peri-implant diseases. Dental caries and enamel hypoplasia are not included as key categories, making this the correct answer.

In the 2017 classification, how is periodontitis staged and graded?

• Based on patient age and sex

• According to clinical attachment loss and gingival color
• Based on severity, complexity and on progression risk of disease

• Based on periodontal pocket depth

Answer explanation

Staging intends to classify the severity and extent of a patient’s disease.

Grading aims to indicate the rate of periodontitis progression.

Why is it important to distinguish between periodontal health on an intact versus a reduced periodontium?

• Because treatment costs differ
• Because plaque control is unnecessary in a reduced periodontium
• To guide diagnosis and tailor management strategies based on history of periodontitis
• To determine the presence of dental caries

Answer explanation

1. Clinically healthy gingiva on intact periodontium

2. Clinically healthy gingiva on reduced periodontium

- stable periodontitis patient

- non-periodontitis patient

Which of the following is a correct pairing of peri-implant disease and its diagnostic criterion?

• Peri-implant health – bone loss
• Peri-implant mucositis – suppuration and mobility
• Peri-implantitis – bleeding on probing and progressive bone loss
• Peri-implantitis – plaque only, without inflammation

Answer explanation

What is the primary purpose of the BPE?

• Diagnose periodontitis

• Screen for periodontal treatment needs

• Replace full periodontal charting

• Measure gingival thickness

Answer explanation

The primary purpose of the BPE is to screen for periodontal treatment needs, helping identify patients who may require further periodontal evaluation or intervention.

BPE is not suitable for:

• Children aged 7
• Adults aged 40
• Implant screening
• Smokers

Answer explanation

BPE is not suitable for assessing dental implants because the tissues surrounding implants respond differently to probing compared to natural teeth. Specifically, the peri-implant tissues are less resistant to probing, and deeper probing depths can be found even in healthy sites due to the anatomical position of the implant and the way the tissues connect to it, making the BPE's simplified scoring system unreliable. 

Which of the following is true about the WHO (CPITN) probe?

• It has a sharp tip to detect bleeding
• It is only used for implant assessment
• The ball end helps detect subgingival calculus
• It is used to measure gingival width

Choose the wrong statement for the ball end on the CPITN probe.

• It causes tissue trauma

• Enhances patient comfort

• Aids in detecting subgingival calculus

• Supports consistent, gentle probing pressure

Answer explanation

The statement 'It causes tissue trauma' is incorrect because the ball end of the CPITN probe is designed to minimize trauma, enhancing patient comfort and aiding in the detection of subgingival calculus.

BPE can detect attachment loss accurately.

• True
• False

Answer explanation

BPE codes themselves don't distinguish between true pockets and pseudopockets

BPE score that can be managed in the primary care dental clinic is

• BPE 2

• BPE 3

• BPE 4

• BPE 5

• BPE 6
