摘要： A dental treating apparatus according to the present invention includes: a hand piece; a head unit; a driving unit; a resistor for load detection; a load comparing unit; and a control unit. The hand piece drivably holds a cutting tool on the head unit. The driving unit drives the cutting tool in a normal rotation direction or in a reverse rotation direction. The resistor for load detection detects a load applied to the cutting tool. The load comparing unit compares the detected load and a reference load each time driving for rotating the cutting tool in the reverse rotation direction by a predetermined rotation angle is performed. The control unit controls the driving unit based on a result of comparison by the load comparing unit.

摘要： The present invention is directed to a dental treating apparatus including: a hand piece; a power source (micro motor); a driving unit (motor driver); and a controller. The driving unit drives the cutting tool so as to be switchable between first driving in which the cutting tool is driven clockwise and second driving in which the cutting tool is driven counterclockwise. When a rotation direction in which the cutting tool cuts an object to be cut is defined as normal rotation and a rotation direction opposite to the normal rotation is defined as reverse rotation, the controller sets the first driving as driving for the normal rotation when a first cutting tool rotated clockwise is held on the head unit, and sets the second driving as the driving for the normal rotation when a second cutting tool rotated counterclockwise is held on the head unit.

摘要： A dental treating apparatus according to the present invention includes: a hand piece; a head unit; a driving unit; a control unit; a load specifying unit; and a load comparing unit. The hand piece drivably holds a cutting tool on the head unit. The driving unit drives the cutting tool in a normal rotation direction or in a reverse rotation direction. The load comparing unit compares a load detected and a reference load. During a normal rotation period until driving for rotating the cutting tool in the normal rotation direction by the driving unit satisfies a predetermined first condition, the control unit maintains a rotation direction of the cutting tool in the normal rotation direction, and when a result of comparison by the load comparing unit attains a predetermined result during the normal rotation period, the control unit controls the rotation direction to the reverse rotation direction.

摘要： An apex-locating method and device for determining the depth position of the apex in a dental root canal. It uses a device making it possible to form a circuit including a first probe electrode inserted into the root canal of a tooth, a second electrode in conductive contact with an oral mucous membrane, frequency-generating elements able to produce alternating electrical signals at a number of frequencies, and elements for measuring electrical magnitude of alternating signals in the circuit. Provision is made for exciting the circuit and measuring the levels of magnitude of the alternating signals, respectively at low frequency and at high frequency and for detecting a point of intersection where the two levels measured at low and high frequencies meet and become substantially equal, these frequencies being sufficiently far apart for this point of intersection to exist. This point gives the position of the apex.

摘要： An electronic device for locating the apex of a root canal within a tooth of a dental patient has a display screen on a display component to provide an image indicating when the apex of a root canal has been located. A free end of a first electrical lead is provided for placement within the root canal or in contact with an electrically conductive tool within the root canal. A free end of a second electrical lead is used to establishing a ground on a conductive portion of the dental patient such as a tissue surface within the mouth. The opposite ends of each of the leads is connected to the display component. Removeably attached to the display component is a lead carrier. The detachable lead carrier and the leads mounted thereon can be sterilized as a unit and then attached to the display component, which is bagged in a sterile barrier, for performing the apex locating procedure. The apex locator has one or more mounting structures for placing the display in a location adjacent the patients head, attached to adjacent instrumentation, or attached to the dental practitioner's hand or arm such that the display image is readily visible by the dental practitioner during the apex locating procedure.
