The Jamaican population has a very high incidence of three canal maxillary premolars. In my practice, since 2001, I have treated over 40 cases with this anatomic aberration. Successful treatment of these teeth start with an accurate radiographic 
interpretation of the 3 root form, and applying microscope assisted techniques of modified access preparation, canal location and biomimetic mechanical preparation of the canal space.
Precision endodontics is at it’s best when these principles are applied to the clinical management of three canal maxillary premolars.
Attached is a case where for the first time I retreated both maxillary first and second three canal premolars in the same patient . # 12 is restored with self cure resin and # 13 with bonded amalgam.
Any comments are welcome.
