Answer: 4
The tooth with the poorest prognosis after furcation therapy due to limited instrument accessibility is the maxillary first premolar.

ANUG is caused by Borrelia vincenti and Fusobacterium.
Which of the following serves to increase the width of attached gingiva on tooth with isolated gingival recession
1) Laterally positioned pedicle graft
2) Free gingival graft
3) Apically displaced flap
4) All of the above
Periodontics
Answer: 1
Increasing the width of attached gingiva is important for periodontal
health and aesthetics. Here’s how these techniques generally perform:
Laterally positioned pedicle graft involves using
tissue from an adjacent site to augment the width of attached gingiva at
the recession site without losing blood supply, making it quite
effective.
Free gingival graft can also increase attached
gingiva, but since it comes from a donor site, the healing and
appearance may not be optimal compared to pedicle grafts.
Apically displaced flap primarily repositions
existing tissue and may not necessarily increase the width of attached
gingiva.
While options 2 and 3 can contribute to increased connective tissue, they
don't specifically target the enhancement of attached gingival width as
effectively as a laterally positioned pedicle graft.
Plasma cell gingivitis is seen in individuals having the habit of chewing which of the following types of flavoured chewing gum?

ANUG affects the
1. Attached gingiva
2. Marginal gingiva
3. Alveolar mucosa
4. Interdental papilla
Periodontics
Answer: 4
ANUG primarily affects the interdental papilla.
The most prominent immunoglobulin in sulcular fluid is
l . Ig A
2. Ig E
3. Ig M
4. Ig G
Periodontics
Answer: 4
The most prominent immunoglobulin in sulcular fluid is IgG.
Sulcular fluid is the fluid found in the space between the tooth and the
surrounding gingival tissue. It contains various immunoglobulins that contribute
to the local immune defense against oral pathogens. While IgA is the most common
immunoglobulin found in saliva, which is closely related to the oral cavity, the
most prominent immunoglobulin in sulcular fluid is actually IgG. IgG is the most
abundant antibody in the blood and can be found in various bodily fluids,
including sulcular fluid, where it provides protection against infections and
inflammation. IgE is associated with allergic reactions, IgM with early immune
responses, and IgA with mucosal surfaces
Gingival inflammation extending the deeper supporting tissues and destroying part of the periodontium would be diagnosed as
1 acute necrotizing ulcerative gingivitis
2 chronic gingivitis
3. gingival pathosis
4. juvenile periodontitis
Periodontics
Answer: 4
Juvenile periodontitis involves inflammation that extends beyond the gingiva
into the supporting structures of the periodontium, leading to significant
tissue destruction.
Not a contributing factor for ANUG
1. Pericoronal flap
2. Poor oral hygiene
3. Smoking
4. Aphthous ulcers
Periodontics
Answer: 4
Aphthous ulcers are not a contributing factor for ANUG.
