II: The effectiveness of commonly taught clinical parameters in developing an accurate prognosis . McGuire MK, Nunn ME. Previous studies have commonly pointed out that breakdown of interroot periodontal tissue in multirooted teeth, that is furcation involvement (FI) is one of the main factors determining the prognosis of multirooted teeth (Hirschfeld and Wasserman, 1978; McFall, 1982; McGuire and Nunn, 1996). 26. Similarly, in a series of studies, McGuire and Nunn (1991, 1996) 2, 3 concluded that it is difficult to predict the prognosis of teeth with an initial prognosis of less than good.

Classically, a tooth that was affected with greater than 50% bone loss was given a questionable to hopeless prognosis.
