Primary Maxillary Canine

Where are the primate spaces?

-Mesial of the Maxillary Canine

-Distal of the Mandibular Canine

Tooth with the best developed lingual anatomy

Maxillary Lateral

Most likely to have dens-in-dente

Maxillary Lateral

Greatest constriction from pulp horn chambers to canal

Maxillary 1st Premolar

Premolar most likely to have 1 root and 1 canal; no bifurcation

Mandibular 2nd Premolar

The anterior tooth most likely to have a bifurcated root

Mandibular Lateral

Only tooth with two triangular ridges on one cusp

Maxillary 1st Molar

The only tooth w/ a mesiolingual groove

Mandibular 1st Premolar

Which anterior and posterior teeth possess pseudo-pentagonal shape?

Anterior: Max/Mand Canine

Posterior: Max/Mand 1st & 2nd Premolars

Typically for posterior teeth the occlusal surface is more visible from which side

Distal Side

Which tooth is an exception where more occlusal surface is seen from the mesial side?

Mandibular 1st Premolar (due to the angular mesial marginal ridge)

Which teeth are an exception to developing from 4 lobes?

Maxillary 1st Molar

Mandibular 1st Molar

Most common tooth to have palatoradicular groove and lingual pit

Maxillary Lateral

Most common tooth the have cervical projections

Maxillary 1st Molar

Typically facial heights of contours are in the cervical thirds. Which teeth are the exceptions ?

Mandibular 1st Molar

Mandibular 2nd

(At the junction of cervical and middle thirds)

How does the CEJ change from anterior to posterior teeth.

It gets flatter

Anterior Teeth

Rank the cusps on the Mandibular Molars (largest to smallest)

Mandibular 1st Molar: MB>ML>DL>DB>D

Mandibular 2nd Molar: MB>ML>DB>DL

Rank the cusps on the Maxillary Molars (largest to smallest)

Maxillary 1st Molar: ML>MB>DL>DB>5th cusp

Maxillary 2nd Molar: MB>ML>DB>DL

Compare the shape of permanent and primary canines from the facial view

Permanent Canines : Trapezoidal

Primary Canines: Diamond
