| Abstract | ||
| Purpose: Evaluation of pharmaceutical compounds (Ciprofloxacin, Clotrimazole, Chitosan) and prepared plant extracts (Clove, Thyme) as corrosion inhibitors for Cu Ni Ti orthodontic arch wire, in acidulated phosphate fluoride solution (APF) (0.5 % NaF + 0.17 % H3Po4) adjusted to pH of 3.5. simulating commercial fluoride containing products. Materials and Methods:Forcorrosion testing, eighty specimens (10 mm in length) were investigated by pontiodynamic method (five specimens for 0.5% NaF (control group) and five specimens for different corrosion inhibitors ). For Surface roughness and Scanning electron microscope examination, a representative samples from each group were investigated. ANOVA and Tukey tests were used to compare between groups at significant level (p ≤ 0.05). Results: Significant differences were found in means of corrosion resistance (Icorr ), between different corrosion inhibitors (ciprofloxacin, clotrimazole, chitosan, clove, thyme) and control group. Conclusion: The corrosion rate was significantly decreased by adding different corrosion inhibitors, indicating the formation of protective layer on the wire surface. | ||
