These results suggest that the commonly used IOTN as a clinical assessment tool for orthodontic treatment need should be reinforced by OHRQoL measures, like the OASIS, expressing patients' perceived treatment need.

OHRQoL deteriorates in children during orthodontic treatment. There is evidence that SE can be a protective factor in OHRQoL during orthodontic treatment.

Aims:The aims of this study were to investigate batch-to-batch differences in mechanical and thermal properties of 22 commercial nickel-titanium wires and evaluate the surface quality. Secondly the percentages of superelasticity at mouth temperature were measured.
