Which oral management software is better now?

There are quite a few softwares on the market now, with little difference in functions. It is important to see his after-sales service and future upgrades. At present, I think it's good to relax the dentist. To tell the truth, what I like is his after-sales service. I called at 22 o'clock in the evening, and the staff answered questions, but I think the easy dental service is in place.
