چکیده
composed of Ti only, whereas the Ortho 2 (OH) bracket was eomposed of Ti {base) and Ti-6Al-4V in mierohar'dness. Further on microhardness, the values of the OR bracket at the base and wings were different・. On the release of elements, it was significant only in the aeet・ie NaF solut・ien of pH 3.5, Hewever, the release {)f Al (6.11 ± O.93 ppm) and V (1.16±O.40 ppm) in this so]ut・ion was lew. In eonclusion, an aeetic NaF solution of low pH eould damage Ti-based orthodontic brackets.

Effect of acetic NaF solution on the corrosion behavior of stainless steel orthodontic brackets.
This study assessed the effect of acetic NaF solutions on stainless steel orthodontic brackets. Acetic acid was added to a 0.1% NaF solution to make two solutions, one with pH 3.5 and the other with pH 6. For the two different stainless steel brackets (Tomy, Dentaurum) used in this study, they had a similar elemental composition--except with Mo (molybdenum) in the Tomy bracket. The brackets wer...
متن کاملThe effect of fluoride ions on the corrosion behaviour of Ti metal, and Ti6-Al-7Nb and Ti-6Al-4V alloys in artificial saliva.
Metallic materials used for manufacture of dental implants have to exhibit high corrosion resistance in order to prevent metal release from a dental implant. Oral cavity is aggressive towards metals as it represents a multivariate environment with wide range of conditions including broad range of temperatures, pH, presence of bacteria and effect of abrasion. An increasing use of various Ti-base...
متن کاملEffect of acetic NaF solutions on fluoride-containing dental restorative materials.
The aim of this study was to evaluate the effect of acetic NaF solutions on fluoride-containing restorative materials. As the pH value of solution decreased, the degree of microhardness change in restorative materials increased- regardless of product. Dyract AP (DA) and F2000 (F2) (polyacid-modified resin composites) showed the greatest decrease in microhardness after immersion for three days. ...
متن کاملEffect of Three Different Remineralizing Agents on White Spot Lesions; AnIn Vitro Comparative Study
Background and Aim: White spot lesions (WSLs) are common occurrence following orthodontic treatment, this study sought to compare the remineralizing potential of fluoride, MI Paste Plus (CPP-ACP-F) and Remin Pro for treatment of WSLs. Materials and Methods: This in vitro study was conducted on 56 sound human premolars that extracted for orthodontic purposes. Teeth were cleaned and their root...
متن کاملVariations in surface characteristics and corrosion behaviour of metal brackets and wires in different electrolyte solutions.
The aim of this study was to assess the surface characteristics and to compare the corrosion potential of metal brackets and wires in environments containing different media. Four brands of metal brackets and two types of orthodontic wires [stainless steel and nickel-titanium (NiTi)] were investigated. An electrochemical assay was used to compare the corrosion potential (V) of the brackets and ...
