That study says that you can’t tell whether 12 or 24 month cleanings are better.
It does not compare cleaning with never cleaning. It is not evidence that you should never do a dental clean. It does not refute the idea that cleanings are beneficial.

I'm not here to tell you personally what you should or shouldn't do. By all means keep doing dental cleanings, continue seeing your chiropractor, routinely checkup with your naturopath or guru, or whoever else you want to pay money to for whatever reason you want.
I'm just pointing out the objective fact that there is no evidence that doing so will provides any observable health benefit. It might benefit you psychologically, it might encourage you to take better care of your teeth if you see your dentist regularly, who knows... but as far as the science goes, well there just is nothing to substantiate dental cleaning.
