It's pretty unlikely you'll be wandering Paris in shorts - especially since you're used to such warm weather -- the oldtimers count mid-May as the final frost date! (sometimes it works that way, sometimes it doesn't -- but they publish garden advice to protect your plants until mid-May).
Dental Health Maintenance Organizations (DHMOs) Defined. A dental health maintenance organization (DHMO) is a structured type of dental plan. In this type of plan, a set group of dentists provides broad and affordable care at a low monthly premium. The dentists who work with DHMOs receive a fixed fees each month. Most of the work is done at no cost or for a reduced price.
Additionally, the cause of approximately 20 percent of all cancers is not known, and there is reason to suspect that DHMO may play some role in these as well. Clearly, more research is needed before DHMO's role is fully enumerated.
