Tobacco smoking is the most common predisposing cause of which of the following
1. Cyclic neutropenial
2. Juvenile periodontitis
3. Necrotising ulcerative gingivitis
4. None of the above
Periodontics
Answer: 3
Tobacco smoking is the most common predisposing cause of necrotizing ulcerative gingivitis.
ANUG affects the
1. Attached gingiva
2. Marginal gingiva
3. Alveolar mucosa
4. Interdental papilla
Periodontics
Answer: 4
ANUG primarily affects the interdental papilla.
Which of the following gives historical record of past periodontal activity and is useful in monitoring success of periodontal therapy
1) Presence of bleeding
2) Probing depth
3) Clinical attachment
4) Recessive of gingiva
Periodontics
Answer: 2
Probing depth measurements provide historical data on periodontal attachment
levels, reflecting the past and present condition of periodontal health.
Tracking changes in probing depth is critical for assessing treatment success
and disease progression
Psychosomatic factors play an important role in the etiology of
1. acute necrotizing ulcerative gingivitis
2. acute herpetic gingivostomatitis
3. juvenile periodontitis
4. acquired immunodeficiency syndrome
Periodontics
Answer: 1
Psychological stressors can contribute significantly to the onset and
exacerbation of acute necrotizing ulcerative gingivitis, which often occurs in
individuals under stress or with compromised immunity.
After PD surgery immediate recall of patient is done after
1) 1 week
2) 2 week
3) 3 week
4) 4 week
Periodontics
Answer: 1
Following periodontal surgery, a one-week recall is standard practice to
evaluate the surgical site, ensure proper healing, and address any immediate
postoperative concerns.
A tight grasp by the operator on the explores will
1. Prevent tactile sensitivity
2. Provide greater maneuverability
3. Prevent muscle fatigue of the fingers
4. All the above
Periodontics
Answer: 1
A tight grasp by the operator on the explorer will prevent tactile sensitivity.
Cervical abrasion is usually the result of
1. acidic fluids
2. sulcular brushing
3. gingival sulcular fluids
4. horizontal brushing
Periodontics
Answer: 4
Cervical abrasion is often caused by improper brushing techniques, particularly
horizontal brushing, which can wear away the enamel and dentin at the cervical
area of the teeth.
Subgingival curettage may result in all of of the following, except
1. root exposure
2. increased height of the gingiva
3. elimination of pockets
4. root sensitivity
Periodontics
Answer: 2
Subgingival curettage typically involves the removal of diseased tissue and can lead to root exposure and increased sensitivity. It may also help eliminate periodontal pockets. However, it does not result in an increased height of the gingiva; rather, it may lead to a reduction in gingival height due to tissue removal.
