2. Treatment Guidelines Premises Most patients are referred when disease is severe resulting in more tooth loss and treatment that is complex and expensive Most patients are referred when disease is severe resulting in more tooth loss and treatment that is complex and expensive When treatment is initiated during the early stages of disease, success is more likely, treatment is more conservative, and fewer teeth are lost When treatment is initiated during the early stages of disease, success is more likely, treatment is more conservative, and fewer teeth are lost Risk predicts the future severity of disease Risk predicts the future severity of disease Treatment including the need for referral to a periodontist should be based on Risk and Disease Treatment including the need for referral to a periodontist should be based on Risk and Disease Courtesy PreViser Corporation, all rights reserved
