Endo Questions for the RWE Faculty:: Need advice about shaping the molar canals
Regarding size, it all depends on the size of a given tooth. There are no cookie cutter answers; but most of the time, a size 30/04 is a minimum; but if you have a very thin, curved root then a 25/04 may be the only option. There could also be a case where a size 35 04 40/04 may be needed (or even larger depending on the age of patient and root formation.) So, unfortunately not hard and fast rule and you'll have to make a call based on the specific case at hand.
