Locating Second Mesiobuccal Canals (MB2)

Leave No Canal Untreated with Ultrasonics

Studies on maxillary first molar anatomy show that the second mesiobuccal canal (MB2) is present in 65-90% of the cases. The orifice for the MB2 is usually located along an imaginary line connecting the primary mesiobuccal canal and the palatal canal. Ultrasonic instrumentation with a diamond coated insert (E2D or E6D) along that imaginary line will often reveal the MB2 orifice location. Clinically, the use of magnification and ultrasonics is the most effective technique to locate the MB2 canal.

E2D

E2D – Conical Diamond

The E2D – Conical Diamond is indicated for both side and end cutting, enlarging the ishtmus and troughing.

  Ideal 20% Max 30%

E3D

E3D – Ball Diamond

The E3D – Ball Diamond provides fine cutting control when troughing yet it is less aggressive than the E6D – Pear Diamond. It is designed to remove coronal obstructions, find canals, restorative materials, calcifications, etc. The E3D creates a smooth, flat, clean troughing groove that eases canal location. It can also be used to refine prep margins and box preps, and to remove caries.

  Ideal 40% Max 50%

E6D

E6D – Pear Diamond

The E6D – Pear Diamond has excellent durability. It is used to locate canals, remove coronal obstructions, calcifications, restorative materials, cements (permanent and temporary), etc. The tip creates a smooth, flat, clean troughing groove that eases canal location. It can also be used to refine prep margins and box preps, and to remove caries.

  Ideal 30% Max 40%

E7D

E7D – Access Diamond

The E7D – Access Diamond has excellent durability. It’s end-cutting action is highly recommended for canal location, removal of obstructions, calcifications, caries, and prep margins refinement.

  Ideal 30% Max 40%

R2

R2 – Flatsonic™

The R2 Flatsonic™ tip is used for selective cleaning of areas left untouched by traditional files. It is an excellent choice for retreatments, especially in long oval canals, where even the R1 Clearsonic would not fit. Very effective in the removal of Gutta-Percha.

Step-by-Step Calcified Canal Location

The orifice for the MB2 is usually located along the imaginary line connecting the main mesiobuccal canal (MB1) and the palatal canal, typically 2-3 millimeters distance from the MB1 orifice.

1 – Using a diamond coated ultrasonic insert (E2D or E6D), create a groove connecting the MB1 and the palatal canals. This will remove secondary dentin, lighter in color.

2 – The dentin covering the pulp chamber floor and its mesial wall must completely removed.

1. Create a groove to connect the MB1 and the palatal canal.

2. Locate the MB2 orifice along the groove.

3. Use an appropriate file to negotiate and prepare the canal.
