Assessment of the electrochemical behaviour of Nickel-Titanium-based orthodontic wires: Effect of some natural corrosion inhibitors in comparison with fluoride.

Background: The aim of this study is to assess the corrosion resistance behaviour of Nickel-Titanium-based orthodontic wires (NiTi) in different concentrations of Sodium Fluoride (NaF) and the corrosion's inhibitory effect of the extracts of some medicinal plants (essential oils, hydrosols and extract).

Material And Methods: In this study we used NiTi (3M) and CuNiTi (ORMCO, 35°C, California) orthodontic wires. The following electrolytes were prepared: Lactate Ringer solution with additions of 0.

Bibliometric study of articles on skeletal Class II malocclusions published in four high impact factor journals.

Objective: Perform a bibliometric analysis of the orthodontic literature on skeletal Class II malocclusions during the first decade of the 21st century.

Materials And Methods: A retrospective, observational, and comprehensive study ranging from January the first 2001 to December 31 2010, based on the articles published in four high impact factor orthodontic journals: Angle Orthod, OCR, EJO, and AJODO (Quotation Report Newspaper of the Scientific Information Institute).

Results: In the 4565 reviewed articles, only 338 were published on Class II malocclusions.
