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.
Odontoplasty is indicated in
1. Grade I furcation
2. Grade II furcation
3. Grade III furcation
4. Grade IV furcation
Periodontics
Answer: 1
Odontoplasty is indicated in Grade I furcation.
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.
Root commonly removed in maxillary first molar during hemisection or root section is
1. Palatal
2. Distobuccal
3. Mesiobuccal
4. None of the above
Periodontics
Answer: 2
The root commonly removed in a maxillary first molar during hemisection or root section is the distobuccal root.
Pigmentation of chemicals in mucosa is due to
1. Increased permeability of blood vessels
2. Local deposition of chemicals in muscosa
3. Subepithelial precipitation in connective tissue at the site due to increased capillary permeability
4. None of the above
Periodontics
Answer: 4
Pigmentation of chemicals in the mucosa is due to local deposition of chemicals in the mucosa.
When doing instrumentation near the cementoenamel junction, cementum completely removed because it is
1. very thin in this area
2. usually softer than subgingival calculus
3. necrotic in the pocket
4. all of the above
Periodontics
Answer: 4
The cementum near the cementoenamel junction (CEJ) is indeed very thin, making
it more susceptible to removal during instrumentation. Additionally, cementum
can be softer than subgingival calculus, and in cases of periodontal disease, it
may become necrotic.
Bone graft procedures are most successful in treating
1. Furcation involvements
2. Deep, two-wall craters
3. Narrow three-wall defects
4. None of the above
Periodontics
Answer: 3
Bone graft procedures are most successful in treating narrow three-wall defects.
Gingival curettage is the treatment of choice for
1. globulomaxillary cyst
2. bleeding gingiva
3. inflamed swollen gingiva
4. fibrous gingiva
Periodontics
Answer: 3
Gingival curettage is a procedure used to remove inflamed and diseased tissue from the gingiva. It is particularly effective for treating inflamed swollen gingiva, as it helps to reduce inflammation and promote healing.
