The main objective of endodontic therapy is the thorough mechanical and chemical cleansing of the entire root canal system and its complete obturation with an inert filling material. Failure to find and fill a canal contributes toward the failure of endodontic therapy .The root canal anatomy of mandibular first molars is complex. Studies of the morphologic structure of root canal systems hav...

We study the eigenspace decomposition of a basic classical Lie superalgebra under adjoint action toral subalgebra, thus extending results Kostant. In recognition Kostant's contribution we refer to eigenfunctions appearing in as Kostant roots. then prove that root systems inherit main properties systems. Our approach is combinatorial nature and utilizes certain graphs naturally associated with p...
