Can I sk a question ...I may be wrong to ASSUME THIS ( as you know what they say ) But I was always under the impression the dental offices make a decent amount of money . if this is the case then $5000 for such a piece of equipment does not seem like such a big deal...Why wouldnt more offcies use it? I am not 100% positve but I am pretty sure when I say that I dont think many if any in our area use one .. I have called alot and brought brochues and spoke to them .( Now will do the same with the velscope brochure, try to get them to get more info) But most in our area dont even have info on the disease..Just wondering and I am sure there is no straight answer.
