At UVA it's against the rules to call anyone doctor who isn't an MD.
1. Academics actually have a better historical- and linguistic claim to the title "doctor" than do physicians and surgeons.
From Wikipedia: "Doctor, as a title, originates from the Latin word of the same spelling and meaning. The word is originally an agentive noun of the Latin verb docēre [dɔˈkeːrɛ] 'to teach'. It has been used as an honored academic title for over a millennium in Europe, where it dates back to the rise of the first universities." [1]
2. In the UK, surgeons are called "Mister" for historical reasons, as explained by a FAQ of the Royal College of Surgeons. [2]
