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
Ideal thickness of graft should be
1. 1.0 to 1.5 mm
2. 0.25 to 0.5 mm
3. 0.5 to 1 mm
4. 2-3 mm
Periodontics
Answer: 1
The ideal thickness for a graft is typically between 1.0 to 1.5 mm to ensure adequate healing and integration.
A young adult shows non-fluctuant, tender and red swelling in the marginal gingival lesion. This is most likely
1. Periodontal abscess
2. Periapical abscess
3. Gingival abscess
4. Periapical sinus
Periodontics
Answer: 3
A young adult with non-fluctuant, tender, and red swelling in the marginal gingival lesion is most likely to have a gingival abscess.
what %age of NaF is used in iontophoresis:
1.1%
2.2%
3.3%
4.4%
Periodontics
Answer: 2
2% NaF is used in iontophoresis. This fluoride treatments brings about granular precipitation in dentinal tubules and reduces tubular diameter.
Lower first molar has furcation involvement with bifurcation caries, treatment of choice is
1. Endodontic treatment followed by hemisection
2. Hemisection followed by endodontic therapy
3. Apical curettage only
4. None of the above
Periodontics
Answer: 1
The treatment of choice for a lower first molar with furcation involvement and bifurcation caries is endodontic treatment followed by hemisection.
Instrument selection for scaling depends upon all of the following factors except
1) Location of calculus deposits
2) Composition of calculus
3) Area of the mouth to be instumented
4) Depth of pockets
Periodontics
Answer: 2
The location of calculus (subgingival vs. supragingival) influences the choice of instrument type (e.g., hand scalers vs. ultrasonic scalers). The area of the mouth (anterior vs. posterior) also affects instrument selection due to accessibility and angulation. The depth of pockets is crucial as deeper pockets may require specific instruments designed for subgingival scaling.
Which aspect of instrument determines whether to remove gross deposits of calculus
1) Angulation and flexibility of blade
2) Angulation and flexibilty of shank
3) Angulation and length of blade
4) Angulation and length of shank
Periodontics
Answer: 2
The angulation and flexibility of the shank are crucial in determining the ability of an instrument to remove gross deposits of calculus. The shank of a dental instrument, such as a scaler or curette, must be designed to allow for proper access and manipulation around the curves and contours of teeth to effectively remove calculus. While the blade also plays a role, the shank's design is more influential in reaching and adapting to the tooth's surface.
