The most important modification of amalgam restorations on primary teeth
1) Rubber dam application
2) Cavity preparation
3) Placement of matrix band
4) Use of zinc free alloy
Pedodontics
Answer: 2
The most important modification of amalgam restorations on primary teeth is cavity preparation (Answer: 2). Unlike permanent teeth, primary teeth have a thinner enamel layer and a larger pulp chamber relative to their size. Therefore, the cavity preparation must be done with caution to avoid pulp exposure and ensure the longevity of the restoration.
The principal advantage of functional type of space maintainer is
1) It is removable
2) Replaces the tooth/teeth
3) Prevents mescal drift of the permanent molar
4) Prevents supraeruption of the teeth of the opposing arch
Pedodontics
Answer: 4
Functional space maintainers are typically made to be removable for ease of cleaning and adjustment, which is essential for the patient's oral hygiene and the overall success of the treatment. While they also replace the tooth/teeth and prevent mesial drift and supraeruption of teeth from the opposing arch, the key advantage is their ability to maintain function and promote proper eruption of the permanent teeth.
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
The existence of a 2 mm diastema between the fully erupted maxillary permanent central incisors of a 7 year old
child may be attributed to
1. a prominent anterior nasal spine
2 a broad nasal septum
3 failure of fusion of the premaxillae
4. the normal eruption pattern of these teeth
Pedodontics
Answer: 4
A diastema, or space between teeth, can be a normal finding in children, especially during the mixed dentition phase. The presence of a 2 mm diastema between the maxillary central incisors in a 7-year-old is often due to the normal eruption pattern of these teeth, as they may not yet be fully aligned or spaced appropriately.
Electronic device is contraindicated in
1. Pacemakers
2. AIDS
3. TB
4. Asthmatics
Pedodontics
Answer: 1
Electronic devices are contraindicated in patients with pacemakers.
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.
