MDS PREP
Radiographs alone can be used to accurately determine the
1. presence of calculus
2. anatomic root length
3. presence of an apical abscess
4. severity of gingivitis
Periodontics
Answer: 2
Radiographs allow clinicians to see the anatomical structure of the root;
however, they often cannot accurately assess conditions like the presence of
calculus or severity of gingivitis.
Subgingival curettage may result in all of of the following, except
1. root exposure
2. increased height of the gingiva
3. elimination of pockets
4. root sensitivity
Periodontics
Answer: 2
Subgingival curettage typically involves the removal of diseased tissue and can lead to root exposure and increased sensitivity. It may also help eliminate periodontal pockets. However, it does not result in an increased height of the gingiva; rather, it may lead to a reduction in gingival height due to tissue removal.
Most commonly used desensitising agent
1) Iontophoresis
2) 2 % Fluoride
3) Formalin
4) Sodium hypochloride
Periodontics
Answer: 2
2% fluoride is one of the most commonly used desensitizing agents in dentistry. It works by strengthening enamel and reducing the permeability of dentin, which helps alleviate sensitivity in teeth. Fluoride treatments are widely used in clinical practice to manage dentinal hypersensitivity effectively.
Transgingival probing is performed
1. To know the bone architecture after the area is anaesthetised
2. To know the level of attachment
3. To determine the disease activity
4. To know the functional occlusal relationships
Periodontics
Answer: 1
Transgingival probing is performed to know the bone architecture after the area is anesthetized.
The following most frequently forms at tooth-tissue interface following flap surgery or curettage
1. Scar formation
2. Adhesion of collagen fibres
3. Long junctional epithelium
4. Collagen fibres parallel to root surface
The most frequently formed tissue at the tooth-tissue interface following flap surgery or curettage is long junctional epithelium.
The term gingival ablation indicates
1) Gingival recession due to faulty tooth brushing
2) Gingival recession accentuated by prominent palatal root
3) Gingival recession due to friction from hard root
4) Gingival recession due to friction from soft tissue
Periodontics
Answer: 4
Gingival ablation is a surgical procedure that involves the removal of a portion of the gingival tissue. It is often used to treat conditions such as excessive gingival overgrowth or to improve the health of the gum tissue. Gingival recession due to friction from soft tissue, such as the tongue or cheek, is one possible outcome of this procedure. It does not inherently involve the removal of tissue due to tooth brushing, prominent roots, or hard tissue friction.
An enamel pearl located on disal furcation of maxillary molar with furcation involvement can be best treated by
1. Flap surgery and odontoplasty
2. Extraction of tooth
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.
Ostectomy procedure is indicated in
1. Physiological architecture of alveolar bone
2. Correction of tori
3. Reverse architecture bone defects
4. Correction of bone ledges
Periodontics
Answer: 3
Ostectomy procedures are indicated for reverse architecture bone defects.
