Dentaport ZX is an electric handpiece designed to do rotary endo but it has an apex locator built into it. A monkey could do a root canal with it.
No, I haven’t tried to merge waterlase and cerec, but I may try it soon. I’ll use a cylinder diamond about 557 in a slow speed handpiece…the dentaport zx… to “file smooth” the prep after I do the bulk reduction with the laser.
