Although this software was envisioned to be the first open source dental practice management software, it never made it past the planning stage.
Open Dental Software, on the other hand, works very well. See http://www.open-dent.com. It is fully functional and has been used by hundreds of dentists for over a year.
Features are extensive and include:
Scheduling

Free E-claims

Perio charting
Timecard

Scanning capabilities
Image organization
Foreign language translation
Full telephone support
And many other features...
Everything you could ever want in a dental software.
