MDS PREP
"Tuberous sclerosis" is seen in
1. Vascular fibroma
2. Leprosy
3. Tuberculosis
4. Bone disorders
Tuberous sclerosis is associated with vascular fibroma.
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.
Failures in maintaining adequate plaque control result mostly from failures in patient
1. neuromuscular skills
2. motivation
3. records
4. recalls
Periodontics
Answer: 2
The primary reason for failures in maintaining adequate plaque control is often
a lack of motivation. Patients may understand the importance of oral hygiene but
may not be motivated to implement effective brushing and flossing techniques
consistently.
Craters in facial and lingual interdental bone are best eliminated by
1) Gingivectomy
2) Osseous reconturing
3) Osseous regeneration procedure
4) Curettage
Periodontics
Answer: 3
Craters in the facial and lingual interdental bone are typically associated with periodontal disease and result from the loss of bone due to inflammation and infection. Osseous regeneration procedures, such as guided bone regeneration (GBR) or the use of bone grafts, are specifically designed to restore lost bone structure. These procedures promote the growth of new bone in the affected areas, effectively filling in the craters and restoring the contour of the alveolar ridge. Gingivectomy and curettage are more focused on soft tissue management and do not address the underlying bone loss, while osseous recontouring may not be as effective in restoring lost bone volume.
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.
Stippling is seen on
1) Marginal gingiva
2) Attached gingiva
3) Interdental gingiva
4) None of the above
Periodontics
Answer: 2
Stippling is typically observed on the attached gingiva, indicating healthy
tissue.
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.
Local irritating factors in gingiva are most likely to give rise to
1. Pyogenic granuloma
2. Generalized fibrous hyperplasia of gingiva
3. Mucosal cubblestoning
4. Periapical abscess
Periodontics
Answer: 1
Local irritating factors in the gingiva are most likely to give rise to pyogenic granuloma.
