Probing depth can be accurately assesed on proximal surface of a tooth by
1. Positioning probe at right angles to tooth surface
2. Walk the probe as close to the contact area as possible
3. Slant the tip of probe apical to contact area
4. Using Naber"s probe
Pedodontics
Answer: 3
Probing depth can be accurately assessed on the proximal surface of a tooth by slanting the tip of the probe apical to the contact area.

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
Band and loop space maintainer is a
1) Passive appliance
2) Active appliance
3) Both of the above
4) None of the above
Pedodontics
Answer: 1
A band and loop space maintainer is a passive appliance used in pediatric dentistry to maintain space for a permanent tooth when a primary tooth is lost prematurely. It does not exert any active forces on the teeth, hence categorized as a passive appliance.
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.
Common clinical sign of occlusal trauma
1. Tooth mobility
2. Fractures of cusps
3. Resorption of alveolar ridge
4. Widening of PD ligament
Pedodontics
Answer: 1
Tooth mobility is a common clinical sign of occlusal trauma.
The electronic probing system "Foster-miller probe" detects

2. Only the CEJ
3. CEJ and pocket depth
4. Furcation involvement
Pedodontics
Answer: 3
The electronic probing system "Foster-Miller probe" detects CEJ and pocket depth.
