RAD TCDHA ACTUAL EXAM 100 QUESTIONS AND ANSWERSbiologic width - answer-space on the tooth surface occupied by the junctional
epithelium and the connective tissue fibers
a mature plaque biofilm - answer-is more pathogenic than the biofilm that first
developed on the tooth surface:
- types of bacteria in biofilm change as biofilm matures.
plaque maturation - answer-plaque biofilm allowed to grow undisturbed= mature
as it matures- colonized with gram negative periodontal pathogens
Effects of Food Impaction - answer-Can strip gingival tissues away from the tooth
surface.
Can lead to alterations in gingival contour =interdental areas difficult for
patients to clean.
trauma from occlusion - answer-excessive occlusal forces that cause damage to
peridontium
signs of trauma from occlusion - answer-Tooth mobility
Sensitivity to pressure
Migration of teeth
Enlarged, funnel-shaped PDL space
Alveolar bone resorption
,Parafunctional Occlusal Forces - answer-Can exert excessive force on the teeth
and to the periodontium
-result from tooth- to-tooth contact when not in the act of eating
therapy- occlusal adjustment/ night guards
Functional occlusal forces - answer-normal forces produced during the act of
chewing food
Primary occlusal trauma - answer-injury to the sound periodontium (with no
previous history of periodontal breakdown) from excessive occlusal forces
- High restorations.
- Excessive force on abutment teeth from partial dentures.
- Changes: wider PDL, tooth mobility,pain.
- Changes are reversible if trauma is removed
Lateral Occlusal Forces: Primary Trauma - answer-Tipping of the tooth within the
socket due to lateral occlusal forces:
Secondary occlusal trauma - answer-injury to the periodontium that was
previously damaged by periodontitis from normal/excessive occlusal forces
may result in rapid bone loss/ pocket formation
Clinical Periodontal Assessment - answer-a fact-gathering process to provide a
picture of the patient's periodontal health status.
, info gathered forms:
-Periodontal diagnosis
- Individualized treatment plan
Periodontal Screening Examination - answer-quick process to determine if a more
comprehensive
assessment is needed
Comprehensive Periodontal Assessment - answer-intensive and in-depth
information-gathering process
Components of the Periodontal Assessment - answer-Gingival inflammation
• Level of free gingival margin
• Recession of the gingiva
• Level of mucogingival junction
• Probing depth measurements
• Bleeding on probing
• Presence of exudate
• Tooth mobility
• Furcation involvement
• Presence of calculus deposits on the teeth
• Presence of dental plaque biofilm
FGM slightly coronal to the CEJ - answer-normal position
