ANTICORROSIVE AND ANTI-FATIGUE CHEMICAL COMPOSITION FOR NICKEL-TITANIUM DENTAL INSTRUMENTS AND A METHOD OF SYNTHESIZING THE SAME

摘要

The embodiments herein disclose a dental anti-corrosive and anti-fatigue chemical composition. The chemical composition stabilizes the passivating oxide layer and reduces the corrosion specifically fretting corrosion. The chemical composition is capable of increasing the fatigue resistance of NiTi rotary instruments lead to increased number of cyclic fatigue in the dental instruments. The chemical composition is synthesized by mixing sodium chloride NaCl (3.5 wt %) and 3-methoxypropylamine (MOPA) 3000 ppm solution (pH=11.1). The chemical composition is stored in carbon steel, stainless steel or aluminum. The chemical composition is applied to the NiTi rotary instruments are by 5 mL of the anticorrosive chemical composition for 24 hours. After root canal treatment and before next time usage the used instruments are cleaned and sterilized. After sterilization, the instruments are immersed inside the solution for 24 hours. After 24 hours the instruments are ready for the next treatment.
