A new water-soluble surfactant copper(II) complex [Cu(sal-ala)(phen)(DA)] (sal-ala = salicylalanine, phen = 1,10-phenanthroline, DA = dodecylamine), has been synthesized and characterized by physico-chemical and spectroscopic methods. The critical micelle concentration (CMC) values of this surfactant–copper(II) complex in aqueous solution were obtained from(More)
We introduced a simple and economical technique for precise placement of lower lingual retainers. Two stainless steel hooks made of 0.6mm wire are placed interdentally in the embrasure area between canine and lateral incisor bilaterally to lock the retainer wire in the correct position. Etch, rinse and dry the enamel surfaces with the retainer passively in(More)
A new surfactant cobalt(III) complex, cis-[Co(dpqc)2(DA)2](ClO4)3, where dpqc = dipyrido[3,2-a:2′,4′-c](6,7,8,9-tetrahydro)phenazine and DA = dodecylamine, has been synthesized and characterized by elemental analysis, UV-Visible, IR and NMR spectra. The critical micelle concentration (CMC) value of this surfactant cobalt(III) complex in aqueous solution was(More)
The success of the dental restorations largely depends on its esthetics, although various literature reviews recommend that anterior teeth midline be placed coinciding the facial midline, the amount of acceptable deviation between facial and dental midline has not been fully investigated. To observe the acceptable deviation between the dental and facial(More)
