Objective: To study the efficiency of chemo-hand instrument removal material.
Methods: The effect on caries removal of N-monochlorochloraminobutyric acid and the electrical dental instrument was detected by the caries detection, microscope and SEM.
Results: The positive for the caries detection and residual caries were zero in both groups.
Conclusion: The effect on caries removal of N-monochlorochloraminobutyric acid is almost the same as the control.
