N2 - The assignment of prognosis is one of the most important functions undertaken in clinical practice, yet there is little evidence to support the current decision-making process which is based on an outdated model of disease etiology and progression. According to The Merriam-Webster Dictionary, “Prognosis” is defined as “the prospect of recovery as anticipated from the usual course of disease or peculiarities of the case.” In medicine, however, the term is commonly defined by the mortality rate. 2018 Apr 10;11(4):580. doi: 10.3390/ma11040580.

Although the inferences that can be drawn from any single study are necessarily limited, application of new approaches in epidemiological analyses to periodontal prognosis, such as CART for survival, should yield important insights into our understanding and treatment of periodontal diseases. tooth mortality) a.
