Name the Roots, canals, and canal spaces for each root for the molars. How many canals should you look for in each?
|
See study sheet.
|
|
|
Which tooth may have a C shaped canal system?
|
Mand 2nd Molar
|
|
|
On which molar is endodonic work normally not done?
|
3rd Molar.
|
|
|
Which molar has often a 1:1 crown to root ration?
|
3rd Molar
|
|
|
Which anterior teeth are most likely to have 2 canals? What would be the names of these canals if you did locate two?
|
a. Mandibular anterior teeth. Always look for 2 canals. Facial and Lingual canals
b. Maxillary Anterior Teeth, 1 root 1 canal, Canal is centered F/L and M/D c. Premolars (Not anteriors, but good to know) Max 1st premolar has 2 roots and 2 canals called the Buccal and Lingual. The Maxillary 2nd has 1 root adn 1 canal, but always good to look for 2, Would be positioned faciolingually. THE Mandibular 1st has 1 root and 1 canal usually, may have 2 positioned faciolingually, may vary in position. The Mandibular second has 1 root and one canal usually. |

|
Which tooth has the longest root in the mouth?
|
Max Canines
|
|
|
Which teeth are wider mesiodistally
|
Max incisors and mand molars
|
|
|
Which teeth are wider faciolingually
|
Mandibular incisory, Canines, All premolars (mandibular premolars close to equal), Maxillary Molars
|
|
|
Which tooth has a kidney bean cross section in the cervical third depression on the mesial surface of crown and root?
|
Maxillary 1st premolar
|
|
|
Which molars are most likely to have a 1 to 1 crown root ratio?
|
3rd Molars
|
|
|
Which tooth has a triangular root cross-section in teh cervical third? ANd where is the canal located in this cross-section? Where are the pulp horns located in the coronal portion of this tooth and what happens if tissue is not removed during endodontic access?
|
Maxillary central incisor, Canal is centered mesiodistally and faciolingually. There are frequently 3 pulp horns located mesially, centrally, and distally. Non-removal of tissue can cause coronal discoloration.
|
|
|
What happens to pulp spaces as we age?
|
Reduced in size, pulp horns gradually reduced in size. Filled in by tertiary dentin.
|
