Morita USA, Inc.'s DENTAPORT ZX Dental Device #### Name of Device and Name/Address of Sponsor | Trade or Proprietary Name: | DENTAPORT ZX | |----------------------------|---------------------------------------------------------| | Common Name: | dental handpiece and root canal length measuring device | | Classification Name: | AC-Powered Dental Handpiece and Root Apex Locator | | Product Code: | EKX and LQY | J. Morita USA, Inc. 9 Mason Irvine, California USA 92618 949-581-9600 Telephone: Facsimile: 949-581-9688 Contact Person: Mr. Junichi Miyata, President Date Prepared: June 25, 2002 ## Intended Use The DENTAPORT ZX is a dental root canal measurement and treatment device that can measure the length of the root canal and enlarge the canal while monitoring the position of the file tip inside the canal. ## Technological Characteristics and Substantial Equivalence The DENTAPORT ZX is a low-voltage electric motor and root canal length measuring device. The DENTAPORT ZX covered by this submission is identical in every respect to the DENTA PORT device already authorized by the FDA under K#022147. The only difference is a change in the instructions for use regarding the sterilization of the device. The new sterilization parameters have been properly validated and result in a sterility assurance level of at least 106. Thus, the changes in sterilization parameters do not raise any new questions of safety or efficacy. 40148758.doc {1}------------------------------------------------ Image /page/1/Picture/1 description: The image shows the seal of the Department of Health & Human Services - USA.
