Exam 1 - Chronic Periodontitis

Question 1

Chronic Periodontitis is most prevalent in what age group?

Answer 1

Adults

Question 2

Sub gingival presentation of Chronic Periodontitis

Answer 2

1. Amount of microbial plaque and calculus is generally consistent with severity of clinical presentation
2. Loss of furcation bone (furcation invasion)
3. Suprabony or Intrabony pocket formation (Equal to or greater than 4 mm)

Question 3

Describe the gingival appearance during Chronic Periodontitis

Answer 3

1. Color - Red or Red-Purple
2. Contour - Edematous or fibrotic inconsistency
3. Consistency - Exhibit altered architecture and contours

Question 4

Probing depths describe the definitions of healthy vs unhealthy depths

Answer 4

1. Healthy = Gingival sulcus or Crevice
   - -> 0-3 mm
2. Periodontal Pocket
   - -> > 4mm
3. Pocket + Recession

Question 5

Classification of Chronic Periodontitis by severity

Answer 5

Slight = 1-2 mm CAL
Moderate = 3-4 mm CAL
Advanced = >5 mm CAL

Question 6

Difference in Pseudopocket vs Periodontal pocket

Answer 6

Pseudopocket = Excessive PD without loss of CAL

Periodontal pocket = Excessive PD with loss of CAL

Question 7

Interdental craters are what percentage of Maxillary vs Mandibular intrabony defects

Answer 7

35% of maxillary

63% of mandibular

Question 8

In treated patients vs untreated patients, how much more does chronic periodontitis progress

Answer 8

Untreated patients lose 3.5 times more teeth

*In a 10 year period, untreated patients lose 3.5-4.0 teeth while treated patients lose 1 tooth

Question 9

In untreated periodontal patients, how much does CAL progress in different areas

Answer 9

FACIAL & LINGUAL areas = 0.1 to 0.3 mm per year

INTERPROXIMAL areas = 0.3 mm per year

Question 10

Name the microbial pathogens in Aggressive Periodontitis

Answer 10

Red complex (P. gingival, T. forsythia & T. denticola)
Aggregatibacter actinomycetemcomitans

Question 11

Answer 11

1. Gram-negative anaerobic enterics
   - Clostridium spp.
   - Klebsiella spp.
   - Enterococcus spp.
2. Candida albicans
3. Epstein-Barr virus

Question 12

Treatment for NUP

Answer 12

• Metronidzole, Fluconazole (Diflucan) or CHX oral rinse

- Soft tissue debridement, Scaling and root planing & 2 month periodontal maintenance interval
