Yes, it's most likely the dent. It doesn't take much for the dipstick reading to be off. You can be 1/2 quart over full and it's pretty high on the stick.
A tip when changing the oil filter: before you put the large round o'ring on the filter base make sure to remove the old one (or two) first. It's not uncommon for a previous monkey to leave the old one there and just tighten the heck out of the canister cover to try and keep it from leaking. Those are usually the same monkeys that neglect to reinstall the spring and the cup over the oil filter.
Beyond any hope for intervention
