Because early childhood is an important period for the colonization of bacteria in the primary dentition, it is possible that antimicrobial factors in saliva may modify these early events. In this study we have followed longitudinally 33 children from predentate to dentate phase and analyzed whole saliva for such salivary factors as lysozyme, lactoferrin, salivary peroxidase, myeloperoxidase, t...

OBJECTIVES The aim of this study was to determine whether patients with purging-type bulimia and/or non-bulimic patients, treated with serotonin reuptake inhibitor SI-5-HT (fluoxetine), have dental erosion and changes in selected buffer components of parotid saliva (bicarbonates, phosphates, urea), compared with the healthy population. METHODS A controlled clinical trial was designed for thre...

In this work, TiNi samples were prepared by Selective Laser Melting (SLM) technology, and the influence of microstructure, fluoride ion, pH value on corrosion behavior in a saline environment was investigated compared with alloy fabricated traditional forging technology. The results indicated that resistance SLM sample slightly superior to wrought due uniform dense oxide film formed surface. Ho...

AIM The aim of this study was to evaluate the release of nickel and chromium ions in human saliva during fixed orthodontic therapy. MATERIALS AND METHODS Ten patients with Angle's Class-I malocclusion with bimaxillary protrusion without any metal restorations or crowns and with all the permanent teeth were selected. Five male patients and five female patients in the age group range of 14 to 2...

The aim of this study was to determine the effect of the oral environment on the corrosion of dental alloys with different compositions, using electrochemical methods. The corrosion rates were obtained from the current-potential curves and electrochemical impedance spectroscopy (EIS). The effect of artificial saliva on the corrosion of dental alloys was dependent on alloy composition. Dissoluti...

Introduction: The aim of this study was to assess the galvanic behavior of different bracket and archwire combinations that are commonly used in orthodontic treatments. Methods: Three types of orthodontic archwires with a diameter of 0.016×0.022 inch and 80 standard edgewise maxillary central incisor brackets were selected. Three groups consisted of different wire-bracket couples and one group ...
