1. A detection tool, comprising:
a detection sensor configured to detect a temperature of air released from an air turbine handpiece; and
a main body that includes a surface, the detection sensor being disposed on the surface to allow the air turbine handpiece to be brought close to the detection sensor,
wherein the air turbine handpiece includes a head and a cutting tool attached to the head, the air turbine handpiece is configured to rotate the cutting tool by a driving force generated by air, the detection sensor includes a thermo-sensitive material which changes color in response to a temperature change, and the thermo-sensitive material changes color when detecting air having a temperature of about 40° C. or more.
