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.

The major growth sites in mandible are:
1.Anterior surface of ramus
2.Condylar process
3.Anterior part of chin
4. Posterior surface of ramus:
1) 1,2,3
2) 2,4
3) 2,3,4
4) 2,3
Pedodontics Answer: 2
•In two ways the overall pattern of growth of the mandible can be represented .It will depend on the frame of reference if both are correct. The chin moves downward and forward if the cranium is the reference area.
On the other hand, it becomes apparent that the principal sites of growth of the mandible are the posterior surface of the ramus and the condylar and coronoid processes if data from vital staining experiments are examined. Along the anterior part of the mandible there is little change
• The chin is almost inactive as a growth site. As the actual growth occurs at the mandibular condyle and along the posterior surface of the ramus it is translated downward and forward. By periosteal apposition of bone on its posterior surface the body of the mandible grows longer , at the condyle accompanied by surface remodeling while the ramus grows higher by endochondral replacement
• Conceptually,wiht is correct to view the mandible as being translated downward and forward,though at the same time it increases in size by growing upward and backward. As the bone moves downward the translation occurs largely. As the bone moves downward and forward along with the soft tissues in which it is embedded the translation occurs largely
Trauma from occlusion in the presence of inflammation
1. Can change direction of pathway of inflammation
2. Has no influence of inflammation
3. Always causes bruxism
4. None of the above
Pedodontics
Answer: 1
Trauma from occlusion in the presence of inflammation can change the direction of the pathway of inflammation.
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.
