I felt the same Hive account@grizgal & Hive account@jasonyoakam, but after further spending time researching their website and looking into the partnerships they are making etc, I actually see an incredibly HUGE industry ahead if the blockchain revolution is truly going to turn the world upside down.
Just the other day a big Dental Clinic in Australia just joined up and they are all really excited about its potential.
I believe the big themes for Dentacoin are to create a Dental Industry you can actually TRUST through their blockchain global review system, to create an environment that encourages patient AND dentists to aim for focus on prevention rather then dentists looking for any excuse to drill and fill for profits.
(My sister is a Dentist and is always sharing her dismay and shock at some of her colleagues she has had to witness along the way. So this is a VERY real problem that Dentacoin are trying to solve)
And finally, they are instigating some kind of Dental Insurance that is meant to be much more fair and available to people around the world. Not exactly sure how, but the whitepaper should break it down.

In the end, the fact that Dental Clinics around the world are already jumping on board and raving about it is a very good sign, and its a very good challenge that this world needs... so i have bout in about an ether worth. Looks like it is just about to go on a run up sometime in the near future too. ;)
But hey.. its the world of crypto... it could fall over too. :p haha
