- 1Permanent Maxillary Central incisor features-blunt apex
-2 developmental grooves
-mesial undulation
-palatal fossa
-mesial incisal edge at a 90 degree angle
-distal incisal rounded - 2Deciduous maxiallary central incisor- buccal bulge
-cingulum on the palatal
-apex blunt
-incisal edge is nearly straight
- 3Permanent Maxillary lateral incisor-mesioincisal 90 degree sharp and distoincisal are more rounded than central incisor
-cingulum
-pit
-root distally inclined
- 4Deciduous Maxillary lateral incisor-mesial incisor sharp
-disto incisal rounded
-cingulum less prominent
-marginal ridges less prominent
-incisal starts to tilt
- 5Permanent Maxillary Canine-longest tooth in the mouth
-tears and grips food
-mesial incisal is shorter than distal incisal
-distal inclination of root
-prominent cingulum
-flattened conical root
-prominent distal root depression
-not so prominent depression on mesial side of root
-darkest tooth in the mouth
- cusp tip in line with long axis of root
-mesial fossa larger
-distal fossa
-palatal ridge
-erupts 11 to 12 years
- 6Deciduous maxillary canine-prominent cingulum
-defined marginal ridges
-root is twice or more the length of crown
-slender tapered root tend to distally incline
-mesial slope is longer than distal slope
-pronounced cervical bulge
-bulbous - 7Maxillary 1st pre-molar-transitional tooth replaces deciduous D
-tears and grinds like canine
-2 cusps
-buccal cusp larger than palatal cusp
-2 roots 80% of the time
-1 root 20% of the time fused with 2 canals and pulp horn - 8Maxillary 1st pre-molar OCCLUSAL-Distal pit

-deep developmental groove - 9Maxillary 1st pre-molar BUCCAL-Buccal ridge
-buccal cusp larger - 10Maxillary 1st premolar-last succedaneous tooth
-replaces deciduous 1st molar
-mix between a canine and a molar - 11Maxillary 2nd pre-molar-smaller than 1st pre-molar
-supplemental groove
