Now that you've removed the sludge, you sort of get a choice to go back with original non-detergent oil and continue periodically cleaning the pan, or detergent oil in your grade/viscosity.
Keep in mind the oil galleries and valve chamber are not cleaned - detergent oil in this area will eventually lift the sludge from there and everywhere else to end up IN your oil or at least a thinner coating of sludge on the motor interior generally. That is the point of detergent oil.
After converting to detergent oil (should you go this way) 3 changes of oil at usual intervals will mostly clean out the rest of the engine to where you need not worry.
Or, forgo a change. You can continue to drop that pan. It works.
There are adherents to both theories of operation.
