Generally no. If you have good irrigation protocol and motion etiquette you should not have too mich loose debri and patency check is not needed between each file. But if you dont, then it’s helpful to do that albeit quite inefficient.

Does introducing k file no 10 could push debris and bacteria beyond Apex ??

In reply to Mina Moheb Yes, too much hand filing and patency checks increases chance of error and pushing debris out. It's a risk and can potentially cause more post op pain.

In reply to Mina Moheb Yes you can, if you have a proper crown down technique or a very good instrumentation habit of making sure debris does not accumulate in the canal during shaping.
