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.
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.

Periodontics
Answer: 1
Plasma cell gingivitis is seen in individuals who chew peppermint-flavored chewing gum.
Which of the following serves to increase the width of attached gingiva on tooth with isolated gingival recession
1) Laterally positioned pedicle graft
2) Free gingival graft
3) Apically displaced flap
4) All of the above
Periodontics
Answer: 1
Increasing the width of attached gingiva is important for periodontal
health and aesthetics. Here’s how these techniques generally perform:
Laterally positioned pedicle graft involves using
tissue from an adjacent site to augment the width of attached gingiva at
the recession site without losing blood supply, making it quite
effective.
Free gingival graft can also increase attached
gingiva, but since it comes from a donor site, the healing and
appearance may not be optimal compared to pedicle grafts.
Apically displaced flap primarily repositions
existing tissue and may not necessarily increase the width of attached
gingiva.
While options 2 and 3 can contribute to increased connective tissue, they
don't specifically target the enhancement of attached gingival width as
effectively as a laterally positioned pedicle graft.
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.
In the conventional finger rest, the finger rest is established on the
1. Other side of the same teeth
2. Tooth surface immediately adjacent to the working area
3. Opposing arch
4. None of the above
Periodontics
Answer: 2
In the conventional finger rest, the finger rest is established on the tooth surface immediately adjacent to the working area.
Subgingival calculus is highest in
1) Lower anterior region
2) Lower bicuspid region
3) Lower molar region
4) Upper molar region
Periodontics
Answer: 1
Subgingival calculus
is often found in the lower anterior region due to the
anatomy and position of the teeth.
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.
