I saw that document a while ago - that is just the Naval Postgraduate School, located in Bethesda at Walter Reed. Those specialties it has listed (if you train in endo, perio, prosth, pathology, radiology, 2 year comprehensive, etc. in the Navy it can only be done in Bethesda). Notice it doesn't include any of the 3 OMS programs (San Diego, Norfolk, Bethesda) or any of the GPR or AEGD programs, across the country. I assume the GPR and AEGD programs just fall under the dental department at their respective military hospital/clinic. The oral surgery programs may fall under the dental department, or even GME department, at their respective sites too. Also, see that the Navy doesn't have its own programs for orthodontics or pediatric residency..so if they don't get already trained orthos and pedos, it's possible, but very rare (since the need isn't that high) that they can put you into a civilian program.
Here is a link I found that shares a bit more how the programs are organized.
