|
Lingual Root Convergence
The roots taper lingually (Jordan/Abrams/Kraus; Woelfel/Scheid). Due to the lingual root taper combined with the twisting of the root on the trunk, it is frequently possible to see the mesial surface of the mesial root (Jordan/Abrams/Kraus; Woelfel/Scheid). Due to the lingual root taper, it is possible to see the distal surface of the distal root (Woelfel/Scheid). |
