Thanks very much. Well, I can flesh some of this out in the statement that I was hoping to make last week but I'll be making, I think, next week on dentistry. I think what's important is that we appreciate, as you say, the work that the community dental service has done, and obviously they have a role in providing care for people who are vulnerable and, because of that vulnerability, can't be seen in general dental services. So, vulnerability, I think it's really important, has to be seen as multifactorial, and should be considered on an individual needs basis. For example, we'd consider people with a learning disability as being vulnerable, but that doesn't necessarily mean that they receive care from a community dental service. So, I think it is important that we take every case and deal with them individually.
