OK, this is an abstract representation of the dental insignia. The triangle represents the network. The circle, is symbolic of "odonto" which is greek for tooth.
PS. If you want graphical elements like gradients, gloss effects, and shadows, please let me know. I'm presenting the logo in it's simplest form, because you can always go back an add these graphical elements. But, you always want to make sure it looks great without all that stuff :)
