Characteristically the mesial side of the root of deciduous maxillary central incisor have a	Developmental groove. This at times is accentuated as a concavity.
The distal surface of root of the deciduous maxillary central incisor is	Convex
A line drawn through the contact areas of the deciduous maxillary canine would bisect a line drawn from	Cervix to cuspal tip
The deciduous maxillary canine has the mesial slope	Longer than distal slope. On contrary the distal slope is longer than mesial slope in a deciduous mandibular canine
From the incisal aspect the deciduous maxillary canine has a shape of a	Diamond
The tip of the deciduous maxillary canine is	Distal to the center of crown
The deciduous mandibular central incisor resembles	Permanent maxillary lateral incisor
The deciduous mandibular central incisor often presents with a developmental depression on the	Distal surface
From the incisal aspect the deciduous mandibular central incisor’s incisal ridge often divides the crown labiolingually with	Equal thickness (bisects)
The widest measurement of the crown of the deciduous maxillary first molar is at	Mesiodistally at contact area
The relative shape and size of deciduous maxillary first molar is suggestive of	Permanent maxillary premolar
In deciduous maxillary first molar, the trifurcation begins	Just below cementoenamel junction. In permanent maxillary first molar the trifurcation begins 4 to 6 millimeters away from cementoenamel junction with a structure called root trunk.
In deciduous maxillary first molar, the smallest root is the	Distobuccal root. The palatal root is the longest and broadest root
The number of cusp in deciduous maxillary first molar is	Three. The permanent maxillary first molars have either four or five cusp. Three cusped deciduous maxillary molar is not uncommon, with a single lingual cusp.
The poorly designed cusp of the deciduous maxillary first molar is the	Distopalatal cusp. The prominent cusp is the mesiopalatal cusp
Among the deciduous maxillary posterior teeth the smallest is the	First molar. Deciduous dentition has no premolars and the first premolar is the smallest.
On the buccal outline of deciduous maxillary first molar, in the cervical third there is a pronounced	Convexity
The crown outline of deciduous maxillary first molar converges	Palatally and distally. Palatal mesiodistal diameter is smaller as compared to the buccal and buccopalatal diameter is greater at distal than mesial side.
The occlusal aspect of the deciduous maxillary first molar is approximately	Rectangular with marginal ridges as shorter side
The normal deciduous maxillary first molar has _____ cusps, _____ triangular fossae, _____ pits and _______ developmental groove.	4, 2, 2, 3
