Here is an interesting case that you least expect to have so many complexity!
mandibular (lower) first molar with a deep-seated or calcified mesial canal presents a complex endodontic challenge. Pulp recession, aging, or chronic irritation can lead to deep-seated mineralized deposits blocking direct line-of-sight access. In this case the lingual canal was located around 2mm below the floor level with a huge calcified tissue blocking the or***ce.
Pre-curve small stainless steel hand files (sizes #08 or #10) with chemical chelators (like EDTA gel) to gently negotiate the calcified or restricted or***ce. But the main tool that would help here is long shank carbides. They are the saviours!!
Keep scouting!! Cheers
