MDS PREP
In a 9-year-old which permanent tooth surface will show greatly increased caries incidence
1) Labial surface of central incisor
2) Occlusal surface of central incisor
3) Mesial surface of central incisor
4) Occlusal surface of lateral incisor
Pedodontics
Answer: 1
In children, the labial (facial) surfaces of anterior teeth, particularly the central incisors, are more prone to caries due to factors such as plaque accumulation, dietary habits, and the developmental stage of the teeth. The labial surface is more exposed to the oral environment and is often less effectively cleaned compared to other surfaces, making it susceptible to decay.
Electronic device is contraindicated in
1. Pacemakers
2. AIDS
3. TB
4. Asthmatics
Pedodontics
Answer: 1
Electronic devices are contraindicated in patients with pacemakers.
Preeruptive caries is most common in permanent
1) Maxillary first molar
2) Maxillary second molar
3) Mandibular first molar
4) Mandibular second molar
Pedodontics
Answer: 4
Preeruptive caries refers to carious lesions that develop on teeth before they have erupted into the oral cavity. Research indicates that the mandibular second molars are particularly susceptible to preeruptive caries due to their position and the timing of their eruption. They are often more difficult to clean and can be affected by factors such as the presence of other teeth and the oral environment
Pocket depth of 6 mm means
1. Width of attached gingiva is 6 mm
2. Width of free gingiva is 6 mm
3. Distance between gingival margin and base of sulcus
4. There is loss of epethelial attachment by 6 mm
Pedodontics
Answer: 3
A pocket depth of 6 mm means the distance between the gingival margin and the base of the sulcus is 6 mm.
Loss of attachment will be equal to pocket depth when
1. Gigival margin is at cementoenamel junction
2. Gigival margin is 2 mm coronal to CEJ
3. Gigival margin is 2 mm apical to CEJ
4. Epethelial attachment is at CEJ but depth of pocket is increased
Pedodontics
Answer: 1
Loss of attachment will be equal to pocket depth when the gingival margin is at the cementoenamel junction.
Periodontal pockets which offer the least possibility for bone regeneration are classified as....................pockets
1. Suprabony
2. One-wall infrabony
3. Two-wall infrabony
4. Three-wall infrabony
Pedodontics
Answer: 2
Periodontal pockets that offer the least possibility for bone regeneration are classified as two-wall infrabony pockets.
The best way to detect bony defects is
1. Radiograph at different angulations
2. Careful probing
3. Surgical exposure
4. Measurement of pocket depth
Pedodontics
Answer: 3
The best way to detect bony defects is surgical exposure.
While using a periodontal probe to measure the depth of the periodontal pocket the pocket is measured from
1. Free gingival margin to the cementoenamel junction
2. Junctional epithelium to the free gingival margin
3. Base of pocket to the cementoenamel junction
4. Base of pocket to mucogingival junction
Pedodontics
Answer: 2
While using a periodontal probe, the pocket is measured from the junctional epithelium to the free gingival margin.
