Endodontic Treatment on Mandibular Molar with Calcified Canals and a “J” Type Lesion, a Five Years Follow Up

      

Root Canal Procedure with Surgical Operative Microscope.
MicroEndodontic.
Case Study Number 156037.

Pre operative film shows a large bony defect reminding us the alleged pathognomonic “J” type lesion. Still, there was no deep and narrow pocket probing. Root canals are not visible neither  in mesial or distal root (calcified canals)

First appointment post operative X ray dental film shows shaped and cleaned canal system with inserted intracanal calcium hydroxide.

Post operative control X ray film in December 2011 shows a nice healing of surrounding hard tissues. Endo treatment finished on 2007 with surgical operative microscope Opmi PROergo from Carl Zeiss.This root canal therapy attempt once more enlightens the huge advantages of microendodontics and calcium hydroxide therapy in order to save teeth with an apparent very bad prognosis.

Treatment protocol:

First appointment: Opening through metal bridge abutment, gaining access to pulp chamber, adherent pulpstones and embedded pulpstones removal, root canal entries locations, cleaning and shaping, rinsing, drying, intracanal medication insertion and provisional obturation material.

Second appointment: Intracanal medication removal, rinsing and final obturation with Pulp Canal Sealer from Kerr and gutta percha

Endodontic material and equipment:

• Shaping and debridment instruments: Stainless steel ISO files, Pro taper files (Dentsply)
• Rinsing solution: sodium hypochlorite 6%
• Drying: sterile paper points
• Calcium hydroxide
• Obturation material: gutta percha lateral and vertical condensation, Pulp Canal Sealer
• Dental operative microscope: OPMI PROergo microscope from Carl Zeiss
