1. Prevent tactile sensitivity
2. Provide greater maneuverability
3. Prevent muscle fatigue of the fingers
4. All the above
Periodontics
Answer: 1
A tight grasp by the operator on the explorer will prevent tactile sensitivity.
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.
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.

3. Lower shank is parallel with the tooth surface being sealed
4. None of the above
Periodontics
Answer: 3
A Gracey curette is correctly adapted when the lower shank is parallel with the tooth surface being scaled.

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.
Bone graft procedures are most successful in treating
1. Furcation involvements
2. Deep, two-wall craters
3. Narrow three-wall defects
4. None of the above
Periodontics
Answer: 3
Bone graft procedures are most successful in treating narrow three-wall defects.
Which of the following changes occur in tissues around teeth o of function for a long time?
1. Atrophy of cementum
2. Secondary dentin deposition
3. Thickening of the periodontal ligament
4. Osteoporosis
Periodontics
Answer: 4
Long-term functional changes around teeth can lead to osteoporosis in the
alveolar bone, which is characterized by a decrease in bone density. This can
affect the support of the teeth.
