Molecular identification and corrosion behaviour of manganese oxidizers on orthodontic wires
نویسندگان
چکیده
In the present study manganese oxidizing bacteria (MOB) were isolated and identified using molecular techniques (16S rRNA gene sequencing) and the electrochemical behaviour of these isolates on orthodontic wires was studied by employing polarization and impedance techniques. Staphylococcus aureus (EF516983), Bacillus pumilus (EF516984), Planococcus rifitioensis (EF516985), Lysinibacillus boronitolerans (EF516986), B. fusiformis (EF516987), L. boronitolerans (EF516988) and B. thuringiensis (EF516989) were identified as manganese oxidizers in orthodontic appliances. It is interesting to note that ten control samples did not have any manganese oxidizers. It reveals that stainless steel enhances the proliferation of manganese oxidizers and accelerates the corrosion of orthodontic wires. Since manganese is toxic to human beings and causes enhancement of nervous disorder, an in-depth study is needed in future.

متن کاملCorrosion of Orthodontic Wires According to Heat Treatment Conditions
Heat treatments are applied to orthodontic wires in order to relieve the stresses arising during orthodontic work. Four types of wires were heated in air, argon or vacuum environments, and cooled in the furnace or in a water bath. The susceptibility to corrosion and mechanical properties of the heat-treated wires were investigated. Heat treatment marginally increased the yield strength and elas...
