How did the dirt get in there??

In any case the only way to be completely sure that all of the dirt is out of the engine is to completely disassemble it.

If it inhaled dirt then the bottom-end, crank and crank-seals will need replacing.

Also, the cylinder takes a beating (scratched cylinder walls) and will need replating along with a piston/rings.

How did it inhale dirt?

It is a ticking time-bomb with the bottom-end/top-end, but you can run it. Just it will eventually gernade and cost even more money.
