A difficult tooth #16 root canal

Written By Peter L

This was a fairly difficult tooth #16 root canal I performed recently. The MB2 orifice was very calcified and buried underneath a substantial amount of tertiary dentine. A significant trough of about 2mm depth along the MB groove was needed to uncover the MB2 orifice. The access was also extended fairly mesial to help obtain straight line access into the MB2 canal coronal 1/3.

Prepared MB1 and MB2 canals. Note depth of MB groove trough relative to pulp chamber floor
