Abstract: | Objective:To explore the best cleaning method through comparing the effect on mechanical function of high-speed dental handpieces by different cleaning methods.Methods:One hundred and twenty new high-speed dental handpieces were divided into A,B and C groups randomly.Dental handpieces in group A were cleaned by manual method;ultrasonic cleaning system and auto-heating cleaning unit were used in Group B and C.Mechanical functions of high-speed dental handpieces were tested one year later.Results:The mechanical functions including rotation speed,clamping force and tarnishing of high-speed dental handpieces in group A were damaged most severely,then group C,and dental handpieces in group B were damaged most lightly.Conclusion:The use of ultrasonic cleaning machine could better maintain mechanical functions of dental handpieces. |
