Objective To investigate the effects of PDCA（plan-do-check-act）cycle in oral equipment management.Method By using PDCA cycle method

the equipments in the Department of Stomatology were statistically checked with the implementation of daily and weekly inspection and year-end summary system

and the problems were corrected and solved in time.Results The inventory backlog decreased from16kinds at the end of 2010to no backlog at the end of 2012.The circulation time of oral equipments shortened from 62days in 2010to 14days in 2012.The backlog cost decreased from 3 500yuan in 2010to zero in 2012with no inventory capacity.Conclusion PDCA cycle can effectively reduce the inventory backlog of oral equipments

shorten the circulation time and reduce the cost for material consumption

and this method should be promoted and widely applied.
