A, Widely separated roots. B, Roots are separated but close. C, Fused roots separated only in their apical portion. D, Presence of enamel projection that may be conducive to early furcation involvement.
* Odontoplasty to reduce or eliminate these
ridges may be required during surgical therapy for an optimal result.
A, Grade I furcation involvement. Although a space is visible at the entrance to the furcation, no horizontal component of the furcation is evident on probing.
B, Grade II furcation in a dried skull. Note both the horizontal and the vertical component of this cul-de-sac.
C, Grade III furcations on maxillary molars. Probing confirms that the buccal furcation connects with the distal furcation of both these molars, yet the furcation is filled with soft tissue.
D, Grade IV furcation. The soft tissues have receded sufficiently to allow direct vision into the furcation of this maxillary molar.
