 Canals negotiation to obtain glode path,  as you can notice 3rd file was introduced thinking it's LATERAL canal then it turned out it's a split of second canal buccally.

due to difficulty of inserting 2 guttapercha all at once in split , one has to be introduced first and vertically compacted allowing enough space for the other one to be followed.

as you can notice one has been compacted while manual file inserted in the other split to avoid any unnecessary blockage by gp

Final obturation


Root canal morphology of the maxillary first premolar appears with different variations, including root diameter, root canal diameter, canal wall thickness, canal diameter, and cross-sectional root canal shape.

The majority of maxillary first premolars have two canals. Of the 2 roots with 2 canals maxillary first premolars, the furcation groove on the palatal aspect of the buccal root has a great influence on the treatment and prognosis .

Thus , to obtain predictable result we have to dedicate plenty of time for radiograph interpretation not to mention requiring CBCT whenever needed .
