41
Primary teeth are smaller in overall dimensions

42
large pulps with long pulp horns
primary teeth
43
more flared and slender roots which extend beyond the crown outlines, thus allowing space for the growth and development of the succeeding permanent teeth
primary molar
44
primary molars
short root trunks and furcation areas approaching the CEJ
45
tf Primary pre-molars have buccal and lingual surfaces that are more convergent occlusally, result in narrow occlusal table
f Primary molars have buccal and lingual surfaces that are more convergent occlusally
46
correct the statement primary teeth; thin enamel with dispersed thickness
primary teeth; thin enamel with consistent thickness
47
difference between primary molar and permanent molars
enamel rods of primary molars at the CEJ point occlusally rather than gingivally as with permanent molars
48
tf Primary teeth have lot of dentin between pulp and dentino-enamel junction (DEJ)
F Primary teeth have little dentin between pulp and dentino-enamel junction (DEJ)
49
comparatively longer and narrower roots with respect to their crowns

52
tf The teeth of children and young people are more sensitive than the teeth of older people to thermal change and dental operative procedures

53
leeway space
Primary molars are wider mesiodistally than the premolars that replace them
54
leeway space
allows space for some mesial movement of the permanent first molars as the premolars erupt
