MDS PREP
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.
Periodontal pack is least effective in
1) Providing splinting action
2) Haemostatic mechanism
3) Pain elimination
4) Antimicrobial action
Periodontics
Answer: 3
Periodontal packs are primarily used for their antimicrobial, haemostatic, and splinting properties. While they provide a good antimicrobial environment and can aid in haemostasis, they are not typically used for pain elimination. The main purpose of a periodontal pack is to deliver medication directly to the periodontal pocket and help stabilize the gum tissue around the teeth. Pain relief is generally managed through other means such as analgesics or local anesthetics.
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.
Instrument selection for scaling depends upon all of the following factors except
1) Location of calculus deposits
2) Composition of calculus
3) Area of the mouth to be instumented
4) Depth of pockets
Periodontics
Answer: 2
The location of calculus (subgingival vs. supragingival) influences the choice of instrument type (e.g., hand scalers vs. ultrasonic scalers). The area of the mouth (anterior vs. posterior) also affects instrument selection due to accessibility and angulation. The depth of pockets is crucial as deeper pockets may require specific instruments designed for subgingival scaling.
Which of the following is not a sign or symptom of periodontal abscess?
1. Localized swelling of the gingiva
2. Tooth sensitive to pressure
3. No response to electric pulp testing
4. Pain in the area of abscess
Periodontics
Answer: 3
A periodontal abscess primarily affects the periodontal tissues and does not
typically alter the health of the pulp, which means the tooth may still respond
to pulp vitality tests.
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.
The following tooth has poorest prognosis after furcation therapy due to limited instrument accessibility
1. Maxillary first molar
2. Maxillary Second molar
3. Mandibular first molar
4. Maxillary first premolar
Periodontics
Answer: 4
The tooth with the poorest prognosis after furcation therapy due to limited instrument accessibility is the maxillary first premolar.

1. Cell occlusivity
2. Tissue compatibility
3. Space making
4. Biodegradable
Periodontics
Answer: 4
Ideal requisites of a barrier membrane include cell occlusivity, tissue compatibility, and space making.
