Unlabelled:
When the supra-marginal dentine of a root-filled tooth is engaged by a crown, it may create a stronger tooth/restoration complex. This has been termed the ferrule effect. This paper reviews the current evidence for this effect and examines the influence various post and core materials have on it. Means of achieving a ferrule are discussed and the importance of planning for failure is considered.
Clinical Relevance:
Provision for the ferrule effect when restoring root-filled teeth with a post-retained crown may optimize the strength of the restored tooth.

Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...
