MDS PREP
A loosely adherent yellowish-white mass of cellular debris and microorganisms
on the teeth is termed
1. oral deposit
2. materia alba
3. dental plaque
4. salivary pellicle
Periodontics Answer: 2
Milky white, soft, and visible to the naked eye, Lacks the organized structure of dental plaquecomposed of Food debris, bacteria, dead tissue cells, leukocytes, and salivary proteins
The main objective of maintenance therapy is
1) To initiate secondary surgical procedures
2) To identify aetiological agent
3) To prevent recurrence of disease
4) None of the above
Periodontics
Answer: 3
Maintenance therapy is designed to support the long-term health of periodontal
tissues after initial treatment. By regularly monitoring and managing
periodontal disease, practitioners can help prevent disease recurrence and
maintain periodontal health.
Gore Tex membrane is used during reattachment procedures to
1. Prevent osseous regeneration
2. Prevent connective tissue attachment
3. To prevent formation of long junctional epithelium
4. All of the above
Periodontics
Answer: 3
Gore Tex membrane is used during reattachment procedures to prevent the formation of long junctional epithelium.
Which of the following represents early effect of primary trauma from occlusion
1) Vertical pockets
2) Generalized alveolar bone loss
3) Undermining resorption
4) Haemorrhage and thrombosis of blood vessels in PD ligament
Periodontics
Answer: 4
The early effects of primary trauma from occlusion can include hemorrhage and thrombosis in the periodontal ligament, leading to inflammation and potential tissue damage.
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.
The bacteria found in gingivitis are located in the
1. alveolar bone
2. periodontal pocket
3. periodontal ligament
4 connective tissue of the marginal gingiva
Periodontics
Answer: 4
In gingivitis, bacteria primarily reside in the connective tissue of the
marginal gingiva and within the plaque biofilm on the tooth surface. This
location contributes to the inflammatory response seen in gingivitis.
The type of bone present labial to anterior teeth is
1. spongy
2. cortical
3. cancellous
4. squamous
Periodontics
Answer: 1
The bone located labial to anterior teeth is typically compact bone but can be
described as spongy or cancellous in some contexts referring to the internal
structure, depending on proximity to the tooth roots.
