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 is a type of barrier membrane used in guided tissue regeneration (GTR) procedures. Its primary purpose is to prevent the formation of long junctional epithelium, allowing for the regeneration of periodontal tissues, including bone and connective tissue. While it does not directly prevent osseous regeneration or connective tissue attachment, it creates a barrier that favors the regeneration of the desired tissues.
Gingival curettage is the treatment of choice for
1. globulomaxillary cyst
2. bleeding gingiva
3. inflamed swollen gingiva
4. fibrous gingiva
Periodontics
Answer: 3
Gingival curettage is a procedure used to remove inflamed and diseased tissue from the gingiva. It is particularly effective for treating inflamed swollen gingiva, as it helps to reduce inflammation and promote healing.
Gingival inflammation extending the deeper supporting tissues and destroying part of the periodontium would be diagnosed as
1 acute necrotizing ulcerative gingivitis
2 chronic gingivitis
3. gingival pathosis
4. juvenile periodontitis
Periodontics
Answer: 4
Juvenile periodontitis involves inflammation that extends beyond the gingiva
into the supporting structures of the periodontium, leading to significant
tissue destruction.
Contraindication for distal wedge removal for periodontal surgery in mandibular molar area is
1. Distal root flutings
2. Presence of deep pockets
3. Insufficient space between distal molar & ascending ramus
4. A soft retromolar pad
Periodontics
Answer: 3
A contraindication for distal wedge removal for periodontal surgery in the mandibular molar area is insufficient space between the distal molar and ascending ramus.
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.
"Tuberous sclerosis" is seen in
1. Vascular fibroma
2. Leprosy
3. Tuberculosis
4. Bone disorders
Tuberous sclerosis is associated with vascular fibroma.
Which of the following structures is most likely to be damaged when per forming flap surgery on the complete mandibular arch?
1. Mental nerve
2. Attachment of mylohyoid muscle
3. Retromolar pad
4. Attachment of buccinator muscle
Periodontics
Answer: 1
The mental nerve is situated beneath the mandibular arch and is at risk during
flap procedures, especially when flaps are elevated or repositioned in that
area.
The first sequential step in osseous resection technique
1. Vertical grooving
2. Radicular blending
3. Flattening interproximal bone
4. Gradualising marginal bone
Periodontics
Answer: 1
The first sequential step in the osseous resection technique is vertical grooving.
