Two canals in the same root could each have their apical foramen or converge into a single foramen. This characteristic could apply to any root containing two canals internally. Still, it is crucial to remember this when preparing the mesial canals of lower molars and mesiobuccal canals of upper molars.

The presence of two canals with separate foramen does not require any particular know-how during the preparation phase but only in the obturation phase. When the two canals converge in a common foramen instead, it is necessary to take some precautions during the shaping phase and ascertain the presence of this anatomic peculiarity as soon as possible. This consideration is to avoid reaching the common foramen from two different angulations, thereby avoiding over-instrumentation, over-enlargement, unnecessary weakening, and eventual stripping of the root.

Regarding the surgical approach, two canals of the same root always have an isthmus that used to contain pulp tissue and now contains debris and bacteria. Therefore, the isthmus must always be included in the retro-preparation and filled with the retro-filling material to succeed.

Educational Objective

Specifically, this webinar will:

• Review the root canals anatomy

• Explain what to do and how to manage the presence of two canals of the same root (clean, shape, and obturate) merging together

• Explain what to do and how to manage the presence of two independent canals of the same root (clean, shape, and obturate)

• Present successful outcomes through a series of clinical cases reviews

Educational Path

The webinar is a recording of a live course and consists of two parts. 

The first part covers the primary course content via lecture. In the second part, the speaker answers questions received during a live session with participants. 

Interaction with the instructor is an essential part of this program, and participants can follow up with the speaker by e-mail at the address provided at the end of the lecture.
