Work Smart.... Not Hard
A Case referred to me lower 1st molar with 2 broken files
4 mm.....20/4.......at apical third.... MB canal
2 mm.....25/6.......at middle third... ML canal
Both canal are mildly curved.... both broken file is beyond the curve
I looked to pre-op shifted xray and realised that the MB and ML canals are confluenced( vertucci type II)
I tried to bypass the most apical file in MB canal and it was very easy for some reason
As the 2 canals were joining by 1 apex ... I shaped and cleaned the MB canal to full wl
Then i only shaped and cleaned the ML canal to the level of broken file.....
Saving time and effort with good outcome
