Treating one root canal

CASE REPORT: A 22 year old male patient presented with pain on his lower right back tooth since 3 weeks on examination lower right third molar tooth (46) was treated with root canal treatment 2 years back and no crown was provided.

Radiograph showed underfilled distal root canal with periapical radiolucency which was the reason for positive tenderness on percussion.

By keeping a young age of the patient in to the consideration total root canal treatment was avoided and hence only under filled root canal was exposed and treated
The estimated working length was determined of the distal root canal by apex locater but it lacked accuracy due to bio-mechanical preparation and apical flare of the root canal hence the proper working length of the distal root canal was determined with IOPA which is showed in the image below                                                                                                                                                                                             

The apical opening of the distal root canal was located at root resorption near periapical radiolucency












The distal root canal was obturated and later on tooth was crowned to provide additional strength. 

(apologies for the bad photograph as due to more transparency in radio-graphic film picture had to be taken in such a way.)













After completion of root canal treatment full ceramic crown was placed which is shown in the following pictures
