The average leeway space in the maxilla (both right and left sides) is
1. 1.8 mm
2. 2.7 mm
3. 3.6 mm
4. 0.9mm
Pedodontics
Answer: 1
The average leeway space in the maxilla (both right and left sides) is 1.8
mm.
Leeway space is the amount of space available for the movement of teeth in the
maxilla and mandible during orthodontic treatment. It is calculated by
subtracting the combined mesiodistal width of the mandibular incisors from that
of the maxillary incisors. This space is crucial in determining the potential
for tooth movement, particularly in cases where there is crowding. The answer of
1.8 mm is a commonly accepted average value in the field of orthodontics.
Total number of centric cusps is
1. 7 in maxillary & 6 in mandibular
2. 6 in maxillary & 6 in mandibular
3. 6 in maxillary & 7 in mandibular
4. 7 in maxillary & 7 in mandibular
Pedodontics
Answer: 3
The total number of centric cusps is 6 in maxillary and 7 in mandibular.

Window-shaped alveolar defect on labial alveolar bone is called
1. Dehiscence
2. Crater
3. Fenestration
4. Trough

Gracey curette No.11-12 are used for
1. Anterior teeth
2. Posterior teeth mesial
3. Posterior teeth distal
4. Posterior teeth facial and lingual
Pedodontics
Answer: 2
Gracey curette No. 11-12 is used for posterior teeth mesial.
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.
Which of the following drugs is used to eliminate all sensations?
1. Anesthetic
2. Analgesic
