Perio Exam 1

Periodontal disease has all of the following effects on the periodontium EXCEPT one. Which ONE is the EXCEPTION?

Which ONE of the following descriptions is ALWAYS associated with moderate periodontitis?

Clinical attachment levels are calculated from measurements made from a fixed point that does not change. Since the bone level in health is approximately 2mm apical to the CEJ, clinical attachment levels provide indication of the extent of bone support for the tooth.

Furcation involvement will not be seen on the radiograph until the bone resorption extends past the furcation area.

The radiograph is a direct method of detecting bone loss. Periodontitis is a disease process with active and inactive periods, so the radiograph shows the true disease process.

_______________ is the widening of the periodontal ligament space caused by the resorption of bone along either the mesial or distal aspect of the interdental (interseptal) crestal space.

Calculating the CAL in the presence of Recession: Mr. Autumn presents to you with a probe depth measurement of 4mm on #22. He claims he is having sensitivity when drinking cold beverages, particularly iced coffee. You measure the GM level with you UNC probe and it appears to be 2mm. What is Mr. Autumns CAL?

Identify the appropriate classification for furcation involvement: The entrance of the furca is clinically visible because of the presence of recession of the GM. Probe will pass completely through furcation.

Identify the appropriate mobility classification for Mrs. Smiles: Your patient in the Fones DH Clinic presents to you with a mobile tooth. Mrs. Smiles explains that she has had a wiggly tooth "for a few months now". It does not bother her bc she chews on the other side. During OHI you can visually see that while she is brushing, #11 is moving in a facial-lingual direction, greater than 2mm of displacement.

When interpreting the results of the PSR, the clinician must be alert for teeth with gingival enlargement or with recession of the GM. In presence of either of these conditions the PSR can give misleading results.

The PSR code assigned to a sextant should represent the most common periodontal finding on any tooth in the sextant.

_________________ refers to clinical information gathered prior to periodontal therapy that can be used for comparison to clinical information gathered at subsequent appts. Documented findings can be used in the long-term monitoring of the pts. periodontal health status.

Which of the following is a component in the foundational elements of evidence-based healthcare?

When using a radiograph to aid in detection of furcation involvement, evident signs that determine if a Nabers probe should be used are:

A new pt. presented to the dental office for an initial examination. The PSR would be an appropriate method to comprehensively assess the pts. periodontal status.
