Technical Data

The bridge sends patient data from Open Dental to the specified text file. Example file:

Mouse, Mickey 02/24/08 (17)






Open Dental then launches Dexis, passing the file name as a command line argument. Example:

C:\DEXIS\DEXIS.EXE @InfoFile.txt

The patient number is the only required field in the text file. This means that Dexis likely organizes everything by patient number, and that patient numbers must be identical with those in Open Dental. This is not a problem for new setups with no patients entered in Dexis yet. But it may present a problem if you already have a number of patients entered in Dexis before you begin using Open Dental. The solution is to change the patient IDs in Dexis to match those in Open Dental. If Open Dental creates a new patient ID# which is different from the old Dexis ID#, you can easily fix it even if you have images in both Dexis charts. In the Dexis Admin window, scroll to the old patient ID# and click Modify Patient. Change the ID# manually to the new Open Dental ID#. The two Dexis charts will be merged into one. It can be easily done on a case by case basis as needed. After a while all your active patients will only have one ID# that matches their OD ID#.


If you were using Dexis in stand alone mode, and/or the patient IDs do not match between your Dexis database and your Open Dental database, then you can contact Dexis to have them renumber the Dexis patient IDs. Dexis will usually renumber patient IDs for their customers for free (or at a nominal price). In order for Dexis to renumber the patient IDs they will request a spreadsheet containing certain patient information (patient ID, last name, first name, middle initial, and date of birth). Open Dental can provide you with this spreadsheet.
