Doctoral Thesis / Dissertation from the year 2001 in the subject Medicine - Dentistry, grade: very good, , language: English, abstract: The work present in this study deals with preparation and characterization of new complexes which contain some transition ions ( Sc3+, Ti3+, V5+, Cr3+, Mn2+, Fe3+, Co2+, Ni2+, and Cu2+) and non transition metal ions ( Ba2+, Ca2+, Zn2+, Cd2+, and Sn2+) with ligands (Thymol, Vanillin, o,m,p-Cresol, Salicylic acid, Methyl salicylaste, Guaiacol, Eugenol, and Menthol).
The prepared complexes were classified in accordance with the nature of the ligand ( monodentate or bidentate) and the valance state of the metal ion, this giving the general formula; [ML2], [ML2. n H2O] and [ML3].
The prepared complexes have been characterized by elemental analysis, molar conductance, infrared and Uv-Visible spectra and magnetic susceptibility measurement.
The measurement of conductivity in chloroform indicate that all the complexes act as non-electrolyte- irrespective of the metal salt used in preparation , the magnetic and spectral measurement assigned the complexes with different geometrical structure viz., tetrahedral, square planar, or octahedral structure.
The prepared complexes subsequently tried as dental filling passing the required tests of color, pH, setting time, consistency, compressive strength, film thickness, microlekage, and antibacterial. The complex [ calcium-guaiacolate] show superiority in this respect and it is hoped that this complex (as dental filling) establish a chemical binding with the calcium of the tooth.
