Chamber aperture

Last day at class we learned how to do the first step in a Endodoncy: the chamber's aperture. What is this? is the endodontic access. The principal objective is to remove the roof of the pulp chamber, find the root canals, give a good form and establish the functional angulation for the preparation of the canals. 

Each teeth has a different anatomy and that's why every teeth has a particular aperture. For the practice, the university starts with fake teeth like this:

• The first theeth is the CENTRAL INCISOR:
• 100% of them have just a only canal
• a young teeth has 3 pulp horns
• we have to give a triangular form

• The second theeth is the PREMOLAR:
• the first superior premolar has 2 canals
• the first inferior premolar and the seconds premolars have 1 canal. 
• 2 pulp horns
• we have to prepare the form like an oval. 

• The third teeth is the FIRST SUPERIOR MOLAR:
• It has 4 canals and 4 pulp horns
• The form is trapezoidal 
• We have to see the 4 canals.

• The forth teeth is the FIRST INFERIOR MOLAR:
• It has 3, 4 or 5 canals and 4 pulp horns
• the form is also trapezoidal or rhomboidal 

I hope you like it.
