Abstract:
Objective To compare drying methods for dental handpiece,and to provide references and guidance for choosing appropriate handpiece drying methods.Methods Four groups were established according to different methods of drying:vacuum drying,compressed air dryer drying,entire automatic hot cleaner drying,and sterilizing machine drying.Four types (with 50 in each type)of handpieces with the same brand were selected:low-speed straight (EX-6C),low-speed bender (NAC-EC),high speed turbine fast handset,and high speed turbine four hole handset.After cleaning and disinfection,each handpiece was subjected to the aforementioned four drying methods,and the mass was recorded before and after drying.SPSS software was used to calculate and compare the drying rate among these drying methods by analysis of variance.Results There were significant differences in the drying rate among four drying methods(P＜0.01).The drying efficiency with vacuum drying was higher than the other three methods.The mean drying efficiency for four types of dentistry handset with vacuum drying method were as follows:low-speed straight(EX-6C)69.93％,low-speed bender(NAC-EC)93.21％,high speed turbine fast handset 92.70％,and high speed turbine four hole handset 94.27％.Conclusion The drying efficiency of vacuum drying method for handset is superior to the other three drying methods.
