Optimizing and restructuring the cleaning teeth motion flow in the stomatology hospital

The paper analyzes the cleaning teeth motion flow of dentist by observing the process of cleaning teeth for the patient in the stomatology hospital with the basic industrial engineering theory and method. It studies also dentist and nurse´s collaborating operation of cleaning teeth. It establishes a new cleaning teeth motion flow by optimizing and restructuring. The research indicates that comparing new cleaning teeth motion flow to the old one before improvement. The dentist´s operation time is saved 25 seconds. The movement time is saved 8 seconds. The waiting time is reduced 276 seconds. The dentist and nurse´s total operation time are reduced 309 seconds.
