Abbreviations: B buccal, MP mesial palatal, DP distal palatal, L lingual
^aModified Glickman classification: Class I, incipient or early stage of furcation involvement, bone destruction is less than 2 mm into the furca; Class II, horizontal bone destruction extending deeper than 2 mm but less than 6 mm into the furca; Class III, horizontal bone destructions communicate between furcae of the tooth, and result in a through-and-through tunnel
^bNot present: no furcation involvement
