Preparation some new complexes of methacrylic acid derivatives and evaluation as a bonding agent in tooth

Abstract EN

Ligands were prepared by reacting Methacrylic acid with each of Ethylene chlorohydrine, Chloro acetic acid, 2-hydroxy benzal Chloride, 2-chloro-6-hydroxy aniline, 2-chloro-6- hydroxy pyridine.

The ligands were formed and then interacted with Ca (II) ; The Complexes resulted from ligand : metal (2 : 1) interaction that have the general formula [Ca (H2 C = C (CH3) CO2R) 2].

Ten complexes were done by preparing a mixture of ligand compounds prepared above and Glutaraldehyde.

The mixture was reacted with Calcium ion taken from healthy teeth solved in concentrated Nitric acid.

Then it was tried to use these complexes as to be bonding materials that connect the composite with the enamel. The complexes were studied by Conductivity, Infrared spectra, biocompatibility, and antibacterial measurements.

The conductivity measurements of the prepared complexes indicated that all the complexes prepared in Methylcyanid solvent at (10-3 M concentration) at 25oC are non-electrolyte.

The infrared spectra showed displacement of stretching vibration ν (C = O) presented in all the complexes.

Also, a band belonged to metal–oxygen bonding stretching was indicate that the bonding occurred via oxygen. As for the study of biocompatibility and antibacterial, it was clear that the prepared complexes had a prohibiting effect on bacteria and fungi, but no negative effect on oral (mouth) tissues.
