9Distolingual cusp is inconspicuous and may even be absent
Maxillary Deciduous First Molar (Lingual Aspect)
10Crown is broader on buccal side than on lingual and broader on mesial than on distal, crown is similar to that of a permanent molar except occlusal table is smaller in comparison
Maxillary Deciduous First Molar (Occlusal Aspect)
11Crown is larger than that of a primary first molar
Maxillary Deciduous Second Molar (Buccal Aspect)
12Crown is rhomboidal in shape (same as maxillary 1st molar), crown has four cusps and one supplemental cusp, oblique ridge connects mesiolingual cusp with distobuccal cusp
Maxillary Deciduous Second Molar (Occlusal Aspect)
13Crown is wide in proportion to length especially when compared to its permanent successor, it resembles permanent maxillary lateral because of the heavy root trunk
Mandibular Deciduous Central Incisor (Labial Aspect)
14Incisal edge is centered over tooth
Mandibular Deciduous Central Incisor (Mesial Aspect)
15Lateral incisor is somewhat larger in all measurements except labiolingual dimension where they are identical, rounded distal edge (similar to Maxillary Lateral Incisor)
Mandibular Deciduous Lateral Incisor
16Both Mandibular and Maxillary Cuspids have similar functional form but differ in dimension, distal cusp slope is longer than mesial on mandibular cuspid (same as permanent cuspid)
Mandibular Deciduous Cuspid
17Tooth does not resemble any other tooth (primary or permanent), two distinct buccal cusps with developmental depression dividing them, no buccal groove between mesiobuccal and distobuccal cusp, mesial cusp is larger than distal cusp
Mandibular Deciduous First Molar (Buccal Aspect)
18Cervical Ridge on buccal surface is prominent; crown appears to lean lingually, buccal crown contour is nearly flat from buccal crest to occlusal surface
Mandibular Deciduous First Molar (Mesial Aspect)
19MB angle is prominent because of cervical ridge on buccal side, cusps listed from largest to smallest; ML, MB, DB, DL
Mandibular Deciduous First Molar (Occlusal Aspect)
20Tooth resembles permanent mandibular first molar but is smaller
Mandibular Deciduous Second Molar (Buccal Aspect)
21Prominent cervical ridge on buccal causes greater lingual tilt to crown than that of permanent molar, mesial root is broad/flatlunt.
Mandibular Deciduous Second Molar (Mesial Aspect)
22Crown is narrower on distal than on mesial
Mandibular Deciduous Second Molar (Distal Aspect)
23All three buccal cusps equal in size, long MD measurement and narrow BL
Mandibular Deciduous Second Molar (Occlusal Aspect)

41Dental Lamina is epithelial tissue within oral cavity that becomes tooth germ, dental lamina forms SUPERFICIAL and BASAL layer
0-5 Embryonic Weeks
42First signs of tooth development seen, dental lamina thickens in downward fashion forming U shape, thickening of dental lamina begins at anterior midline and moves posteriorly
6th Embryonic Week
43Lamina continues to thicken in TEN AREAS of each arch which determine locations of future deciduous teeth
8th Embryonic Week

47Stellate Reticulum (Cap Stage)
Cells contained within OEE and IEE which originate from superficial layer of oral epithelium, protects and cushions IEE cells and allows nutrients to pass through its loosely packed cells
48Stratum Intermedium (Bell Stage)
Forms between IEE and Stellate Reticulum (provides nourishment and protein for IEE cells), characterized by concavity of cap deepening and presence of fourth layer of epithelium
49Mineralization Stage
All crystals have been laid down and will never increase in number
50Maturation Stage
Crystals grow and become tightly packed against one another
51Ameloblast Flowchart
1. Basal layer is a continuation to OEE cells 2. OEE cells continue into IEE cells 3. IEE celss elongate and become preameloblasts 4. Dentin matrix cuts off nutrient flow to preameloblasts. causes polarity change which causes ameloblasts to form 5. Ameloblasts lay down protective layer over enamel (Nasmyth’s Membrane) 6. Ameloblasts flatten out and blend with OEE to form REE 7. REE secretes Epithelial Attachment that holds gingiva to tooth 8. REE is worn away naturally
