Claim Text:
1. A dental treating apparatus, comprising: a hand piece for drivably holding a cutting tool on a head unit; a power source for driving said cutting tool; a driving unit for, when a rotation direction in which said cutting tool cuts an object to be cut is defined as normal rotation and a rotation direction opposite to said normal rotation is defined as reverse rotation, driving said cutting tool with twist driving from a start of driving, wherein the twist driving comprises said normal rotation and said reverse rotation being repeated; a driving state detecting unit for detecting a driving state of said cutting tool, wherein the start of driving is a timing before detecting the driving state of said cutting tool by the driving state detecting unit; and a controller for changing at least one parameter from the group consisting of a rotation angle in said normal rotation, a rotation angle speed in said normal rotation, a rotation angle in said reverse rotation, and a rotation angle speed in said reverse rotation,
