MAXILLARY |
MANDIBULAR |
|
|
Cusp ridge |
Distal longer than mesial |
|
|
Contact |
Mesial: junct. On incisal & mid 3rd. Distal contact: mid 3rd. |
Mesial: Incisal 3rd. Distal: junct. Incisal and mid 3rd. |
|
Proximal outlne |
Mesial: broadly convex, flat in cerv. 3rd. Distal: shallow "s". convex in cerv. 3rd. |
|
|
Crown |
Long as Max central |
|
|
Root length |
3.5 mm lnoger than Max central |
Shorter than maxillary, lacks curvature. |
|
Root Curavature |
Distally in apical 3rd. |
Slight distal |
|
Fossae |
Two-shallow |
Slight |
|
Labial Ridge |
Pronounced |
Slight Mesial to ridge is flat in incisal 3rd. Distal to ridge is even more flteened in incisal 3rd. |
|
Lingual ridge |
Yes. More prominent than mesial and distal marginal ridges |
Slight |
|
Cingulum |
Yes. Centered M.D. |
Lower and less prominent. May be slightly distal. |
|
Lingual View |
Both crown and root more narrow |
Same as max |
|
Marginal ridges |
Distal more pronounced. Shorter than mesial |
Slight. Appears smoothe. Distal more prominent than lingual and mesial. |
|
Buccal Cusp Tip |
Yes. Centered M.D. |
Centered. Mesial cusp slope shorter then distal |
|
Height of contour |
Labial: cerv. 3rd. |
Labial: More cervial than max., still in cervical 3rd. |
|
CEJ |
Mesial: dips incisally 2 mm |
Mesial: curves more incisally then max. |
|
Root Depressions |
Both mesial and distal. Distal more pronounced |
Same as max. |
|
Crown (from occlusal) |
Greater distal ½ w/ marked labial convexity. Distal ½ flat/concave. Mesial ½ is rounded. |
More symmetrical than max. Mesial ½ of rounded and distal ½ flat/concave like max. |
|
Lobes |
3. Middle prominent. |
|
|
Incisal aspect |
Thinner than max. Wedge shaped. *Crown twisted on incisal edge to distal. |
|
|
Incisal ridge |
Labial to long axis of root |
Lingual to long axis of root |
Side notes:
Mesial cusp ridge shorter
No mamelons
Only teeth w/ labial ridge
Greater labiolingually than M.D.
Distal contact more cervical than mesial
Wedge shape proximally
Last teeth lost to disease
