摘要：
The invention provides a method of automatically controlling a root canal cutter tool (4) of a root canal instrument (2), the root canal cutter tool (4) being drivable in rotation by a motor (6) and being associated with a control unit (8) for monitoring the cutting torque (CP) or the torque delivered by the motor, the method comprising: rotating the root canal cutter tool (4) in a predetermined cutting first direction (S1) until the torque (CP) reaches a predetermined limit torque value, which limit value is a function of at least one item selected from the root canal cutter tool (4) and the motor (6)； and when the limit torque value is reached: ． rotating the root canal cutter tool (4) in a second direction (S2) opposite to the cutting first direction (S1) through a predetermined first angle of rotation； and then ． restarting the rotation of the root canal cutter tool (4) in the cutting first direction (S1).本發明提供一種自動控制根管儀器(2)之根管切割機工具(4)之方法，該根管切割機工具(4)可由馬達(6)驅動旋轉且與用於監視切割扭矩(CP)或該馬達遞送之扭矩之控制單元(8)相聯，該方法包括：使該根管切割機工具(4)在預定第一切割方向(S1)旋轉，直至該扭矩(CP)達到預定限制扭矩值，該限制值係選自該根管切割機工具(4)及該馬達(6)之至少一個項目的函數；且當達到該限制扭矩值時：．使該根管切割機工具(4)在與該第一切割方向(S1)相反之第二方向(S2)經預定第一旋轉角旋轉；且然後．重新開始該根管切割機工具(4)在該第一切割方向(S1)旋轉。
