This is a routine clinical case of a mandibular premolar with 2 canals. Also attached is a small article I wrote in which I included this case and some other similar cases as well. Here is the pdf of the Article:
Endo and crowns were done by a general practitioner, after which the patient developed pain and tenderness. I Re-treated both teeth and placed fiber posts to strengthen the hollowed out coronal portion.
Here is a step by step pictorial guide to locating a calcified canal in a mandibular premolar. Pictures show colour differentiation between calcifications and dentine.
This was referred by a clinician who started the case thinking it was a regular premolar. Looking at the radiograph that the referral e-mailed me, I was expecting a Two-canalled premolar. The master-cone radiograph showed the lack of centricity of the two canals i had discovered. I went back in and found the third canal.
