Root Canal Procedure on Calcified Canals. Endodontic Microscope. Case Study Number 414
Second mesiobuccal canal entry (MB-2) in this upper molar was blocked by a 2mm thickness of sclerotic dentine. This canal alone took more than one hour to locate under a dental operating microscope and treat. Missing this one canal with its own portal of exit would have led to an apical abcess wich would have implied an apical surgery or an extraction and an implant supported crown somewhere down the road.
Third X ray image shows a one year post operative recall with perfect healing.
Potential risk factors that might have complicated treatment:
- Canals not visible on mesiovestibular root on pre-operative X ray
- S- shaped curve on palatal root canal
