What is a clinical periodontal assessment?
One of the most important functions performed by the clinician.
Information gathered during assessment forms the basis of the individualized treatment plan for the patient.
What is a more accurate measurement of periodontal support: probing depth or clinical attachment level? (CAL)?
CAL- a more accurate indicator of the periodontal support around a tooth than probing depth measurements.
Provides an accurate means to monitor changes in the periodontal support over time
Loss of attachment is a critical factor in distinguishing between
How is clinical attachment level (CAL) calculated?
1.) When the gingival margin is at the CEJ, no calculations are needed.
Probing depth = clinical attachment level
2.) When the gingival margin is coronal to the CEJ. Probing depth MINUS gingival margin level to CEJ = clinical attachment level
3.) When gin
What is the significance of a mucogingival defect?
Gingival recession results in inadequate or diminished AG.
How is the width of the attached gingiva measured?
Probing depths extending to or beyond MGJ into alveolar mucosa.
What effect does occlusal force have on the periodontium?
Most common clinical sign of occlusal trauma is increasing tooth mobility.
The comprehensive periodontal assessment is rapid information-gathering process to determine health versus disease.
False
The PSR (Periodontal Screening and Recording ) requires that the clinician probe which of the following tooth surfaces?
All surfaces of the teeth
During a comprehensive periodontal assessment, probing depth measurements are recorded on how many surfaces
6 Surfaces
Which of the following is a synonym for exudate?
Pus
Gingival recession means that the fee gingival margin is?
Apical to the CEJ
When measuring tooth mobility, the preferred clinical technique is for the clinician to trap the each tooth between:
Two instrument handle
Furcation involvement is measured with what type of instrument?
Curved periodontal probe
Attached gingiva that is tightly connected to the cementum or periosteum.
True
Which of the following is the most accurate measurement of tooth support?
Clinical attachments level
Clinical Attachment Level (CAL)
An estimate of the true periodontal support around the tooth as measured with a periodontal probe.
Distanced measured from the CEJ to the JE
Probing Depths vs. CAL
Probing depths- measured from the gingival margin to the base of the sulcus or periodontal pocket
CAL- measured from a fixed point- the CEJ- to the base of the sulcus or periodontal pocket
CAL- more accurate measurement of periodontal support than probing
Level of the Free Gingival Margin
Possibility of several different relationships of free gingival margin (FGM) to cementoenamel junction (CEJ)
FGM is at or slightly coronal the CEJ = normal position
FGM is significantly coronal to the CEJ = gingival enlargement
FGM is apical to the CEJ =
Gingival Recession
Exposes root surfaces to oral environment
Recession = tissue destruction.
There can be gingival recession without increased probing depth
Gingival Recession Etiology:
Mechanical Trama, Orthodontic movement, Dental Procedures, Clasps for partial dentures, Crown margins, tooth malposition, periodontal therapy (resulting in tissue shrinkage), oral habits, destructive inflammatory periodontal, disease (bacteria), antomic v
Gingival Recession, Exposed root surfaces:
More susceptible to dental caries.
Thin layer of cementum may wear easier, exposing dentinal tubules.
Lack of interdental col creates food trap
Level of Mucogingival Junction
Junction between the keratinized gingiva and the nonkeratinzed mucosa
Usually easy to detect because of color definition
Keratinized is a pale pink
Nonkeratinized is more thin and vascular
Mucogingival Involvement/Defect
Deviations from normal anatomic relationship between gingival margin and mucogingival junction
Usually minimal to no attached gingiva exists
Occlusal Trauma
Injury to the attachment apparatus as a result of excessive occlusal forces
Classified as: Primary or Secondary
Localized or Generalized
Primary Occlusal Trauma
Excessive occlusal forces placed on a healthy periodontal that produces changes in the periodontal tissues.
Examples: placement of "high" restoration, maligned teeth, and orthodontic movement of teeth
Secondary Occlusal Trama
Normal fires of mastication on a periodontium with bone loss (i.e periodontitis) that produce changes in the tissues
Occlusal trama
Occlusal trauma alone does not cause gingivitis, periodontitis, pocket formation, or gingival recession.
In presence of inflammation periodontal destruction may be accelerated.
When occlusal forces are excessive, beyond the capability of the attachment ap
