(1) 94 per cent of the 33 men examined at Fond-du-lac had sound 
teeth. The 2 persons who made up the remaining 6 per cent had among 
them 10 carious teeth. 
(2) 76 per cent of the 21 women examined at Fond-du-lac had sound 
teeth. The 5 persons who made up the remaining 24 per cent had among 
them 12 carious teeth. 
(3) 62 per cent of the 21 men and old men examined at Chipewyan had 
sound teeth. The 8 persons who made up the remaining 38 per cent had 
among them 34 carious teeth. 
(4) 54 per cent of the 24 men examined at Fitzgerald and Fort Smith 
had sound teeth. The 11 persons who made up the remaining 46 per 
cent had among them 31 carious teeth. 
(5) 58 per cent of the 31 men and old men — Cree — had sound teeth. 
The 13 persons who made up the remaining 42 per cent had among them 
39 carious teeth. 
If to have sound teeth be the mark of a pure Indian, and if to have 
carious teeth an indication that there is a strain of white blood in the 
stock, then the Fond-du-lac men and women are the purest, and the 
Chipewyan band of Chipewyans, the Fitzgerald and Fort Smith bands, 
and the Crees follow in that order. 
(6) And since 80 per cent of the 44 assumedly pure Chipewyans exam- 
ined had sound teeth (the 9 persons who made up the remaining 20 per 
cent had among them 19 carious teeth) 
(7) And since 58 per cent of the 26 Chipewyan -white breeds examined 
had sound teeth (the 11 persons who made up the remaining 42 per cent 
had among them 51 carious teeth) it would appear on this basis that the 
“assumedly pure” Chipewyans are actually more mixed than the Fond-du- 
lac band, though they are very evidently less mixed than the breeds. 
The Crees examined this year at Chipewyan had better teeth than 
the Crees examined last year at Oxford House; for the former had 58 per 
cent sound teeth and the latter only 36 per cent. In fact the teeth of those 
examined in Lake Athabaska region are, on the whole, appreciably more 
free from caries than the teeth of those examined in northeastern Mani- 
toba. 
Of the 39 persons mentioned above, among whom 126 carious or missing 
teeth occurred, a larger percentage had lower than upper teeth affected; 
the proportion being 63 per cent lower to 37 per cent upper. 
The teeth of the right side are affected with somewhat the same fre- 
quency as those of the left; upper right, 52*5 per cent, to upper left, 47*5 
per cent ; lower right, 46 per cent, to lower left, 54 per cent. 
Of 21 persons with only one decayed tooth, in eight cases (40 per cent) 
that tooth is the first lower molar; in three cases (15 per cent) the second 
lower molar; in five cases (25 per cent) the third lower molar; in 1 case 
(5 per cent) the third upper molar; in 1 case (5 per cent ) the second upper 
molar; in 1 case (5 per cent) the first upper pre-molar; in two cases (10 per 
cent) the first upper incisor. In no case was the first upper molar the only 
affected tooth.
