What a better gift for our field. Thank you Dr. Kotsakis and team! ### 5/5 — Excellent App *2023-12-06* To be honest, I was holding on to the old Armitage Classification because it had been ingrained in my brain over the years. I resisted the change to implement the new classification until this app came around. This new app makes the classification a “no brainer”! Answer some basic questions from data we collect from our periodontal exams and boom out comes the Stage and Grade . So easy.
