Reattachment procedures most commonly
1. Reduce pocket depth by formation of long junctional epithelium
2. Reduce pocket depth by reattching periodontal connective tissue fibers
3. Usually heal by secondary intention
4. None of the above
Periodontics
Answer: 1
Reattachment procedures most commonly reduce pocket depth by formation of long junctional epithelium.
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.
Sensitivity of roots after periodontal surgery results from all of the following except
1) Exposed dentine tubules
2) Exposed cementum
3) Formation of plaque
4) None of the above
Periodontics
Answer: 2
After periodontal surgery, root sensitivity is primarily due to the exposure of dentin tubules (option 1). When the root surface is exposed, the dentin becomes sensitive to stimuli because the tubules can transmit sensations to the pulp.
Exposed cementum (option 2) is less likely to cause sensitivity because cementum is not as innervated as dentin. Formation of plaque (option 3) can lead to sensitivity as it may irritate the surrounding tissues and contribute to inflammation.
Finger-on-finger rest is used for scaling on
1. Maxillary posterior region
2. Mandibular posterior region
3. Mandibular anterior region
4. Maxillary anterior region
Periodontics
Answer: 1
Finger-on-finger rest is used for scaling in the maxillary posterior region.
Type of suture recommended for apically displaced flap adjacent to edentulous area is
1. Anchor suture
2. Figure eight suture
3. Horizontal mattress suture
4. Continuous sling suture
Periodontics
Answer: 1
The type of suture recommended for an apically displaced flap adjacent to an edentulous area is an anchor suture.
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.
A Gracey curette is said to be correctly adapted when the
1. Handle is parallel to the long axis of the tooth
2. Angle of blade to the tooth is 40
3. Lower shank is parallel with the tooth surface being sealed
4. None of the above
Periodontics
Answer: 3
The Gracey curette is a dental instrument used for subgingival scaling and root planing. Correct adaptation of the curette involves placing it at the correct angle to the tooth surface to effectively remove plaque and calculus. The lower shank of the curette should be parallel with the tooth surface to allow for proper engagement with the tooth structure.
Systemic conditions which can affect the health of the gingiva are
1. agranulocytos
2. leukemia
3. granulocytopenia
4. all of the above
Periodontics
Answer: 4
agranulocytosis, leukemia, and granulocytopenia—can significantly impact the
health of the gingiva by affecting the immune response and increasing
susceptibility to infections.
