Anchorage, Fairbanks offer competitve IHS/638 salaries 115-130k.
The interior locations and those in the tundra which are usually IHS tribal are in the 130s. All of these programs include some sort of housing subsidy so your rent is nothing or dirt cheap. However, food is expensive and you will feel very isolated from a good meal or shopping. Relocation and 25-30 days time off are included but most of these places are accessible by air only. There isn't much at all to do up there. But if all you want to do is sock it away and don't mind living in a small community playing board games and watching movies at night with your fellow dentists in a cruddy place then go for it.
Southeast Alaska is the most competitive because of the mild climate and scenery. Most of these places will hold out for a residency trained or experienced doc.
If you're looking for adventure out west without the isolation of Alaska there are plenty of IHS positions in the lower 48 that pay just as well.
In my opinion when you consider the gauranteed 20 days off, 10 holidays, good salary, CE, benies, tax free NHSC repayment AND low stress, IHS/Public Health is the only way to go for the first 2-4 yrs out of school. But I am biased because that's what I do.
