A young adult shows non-fluctuant, tender and redness swelling in the marginal ginginal lesion. This is most likely:
1. Periodontal abscess.
2. Periapical abscess.
3. Gingival abscess.
4. Periapical sinus.
Periodontics
Answer: 3
A gingival abscess is localized to the gingiva
and typically presents as a painful, non-fluctuant swelling with redness and
tenderness. It differs from periodontal abscesses, which involve deeper
structures, and periapical abscesses, which originate from the tooth apex.
Reattachment procedures most commonly
1. Reduce pocket depth by formation of long junctional epithelium
2. Reduce pocket depth by reattching periodontal connective tissue fibers
3. Usually heal by secondary intention
4. None of the above
Periodontics
Answer: 1
Reattachment procedures most commonly reduce pocket depth by formation of long junctional epithelium.
When electrosurgery is correctly employed to prepare gingival tissues for making impressions, it will
1. Permanently alter the contour of gingival tissues
2. Reduce the gingival height
3. Remove a thin layer of crevicular gingival tissue
4. None of the above
Periodontics
Answer: 3
When electrosurgery is correctly employed to prepare gingival tissues for making impressions, it removes a thin layer of crevicular gingival tissue.
Crater-like gingival deformities are seen in
1. ANUG
2. JP
3. Chronic gingivitis
4. Adult periodontitis
Periodontics
Answer: 1
Crater-like gingival deformities are seen in ANUG.
A black line on the gingiva which follows the contour of the margin is due to
1. Lead
2. Argyria
3. Iron
4. Mercury
Periodontics
Answer: 4
A black line on the gingiva which follows the contour of the margin is due to mercury.
Which of the following radiographic changes are associated with gingivitis?
1. Increased width of the periodontal ligament space
2. Widening of medullary spaces and loss of trabeculation
3. Irregularity of the crestal lamina dura
4. None of the above
Periodontics
Answer: 4
Typically, gingivitis does not present distinct radiographic changes as seen in
periodontitis, where bone loss is evident. Gingivitis is characterized mainly by
inflammation of the soft tissues.
Lesions in ANUG can be described as
1. Vesiculobullous lesions which are contagious
2. Ulcerative lesions which are contagious
3. Ulcerative lesions infectious but not contagious
4. None of the above
Periodontics
Answer: 3
Lesions in ANUG can be described as ulcerative lesions that are infectious but not contagious.
An enamel pearl located on disal furcation of maxillary molar with furcation involvement can be best treated by
1. Flap surgery and odontoplasty
2. Extraction of tooth
3. Flap surgery and hemisection
4. Flap surgery and root amputation
Periodontics
Answer: 1
An enamel pearl located on the distal furcation of a maxillary molar with furcation involvement can be best treated by flap surgery and odontoplasty.
