Periodontics
Answer: 3
Tobacco smoking is the most common predisposing cause of necrotizing ulcerative gingivitis.
When should the correction of occlusal prematurities be performed?
1 At the same time as soft tissue surgery
2 Before starting soft tissue therapy
3. Gross corrections should be done be- fore surgery and finer adjustments after surgery
4. After tissue healing, following surgery is completed
Periodontics
Answer: 3
Addressing significant occlusal prematurities prior to surgical intervention
prevents undue stress and facilitates proper healing, while finer adjustments
can be made post-surgically.1

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.
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
Definite treatment for herpetic gingivostomatitis

2. Hydrogen peroxide mouth wash
3. Steroid therapy
4. No definite treatment
Periodontics
Answer: 4
There is no definite treatment for herpetic gingivostomatitis.
Vestibular extension procedure results in
1. Increase in width of keratinised attached gingiva
2. Decrease in width of keratinised attached gingiva
3. Increase in width of non-keratinised attached gingiva
4. Decrease in width of non-keratinised attached gingiva
Periodontics
Answer: 3
Vestibular extension procedure results in an increase in width of non-keratinised
attached gingiva
The vestibular extension procedure is a surgical treatment that involves the
apical movement of the vestibular mucosal tissue to increase the width of
attached gingival tissue around a tooth. This procedure typically does not alter
the width of the keratinized attached gingiva, which is the tissue that is
directly connected to the tooth surface. Instead, it primarily increases the
non-keratinized attached gingival width, which is the part of the gingival
tissue that is not directly attached to the tooth but is still important for
periodontal health and aesthetics.
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.

3. Handle
4. Shank
Periodontics
Answer: 4
The part of the instrument that should remain parallel to the long axis of the tooth is the shank.
