Thus 31.4 per cent, of the 10 years' old boys, and 32.7 per cent, of the 10
years' old girls had one or more permanent teeth decayed. The percentages of
children with decayed permanent teeth among the leavers was, for boys, 47.6,
and for girls, 50 3. At both ages the teeth of the girls is a little worse than
those of the boys.
Nose and Throat.
The number of children who had had operations for enlarged tonsils and
adenoids before inspection was 171, or 7.4 per cent, of the children whose
parents were present at the medical inspection and for whom only a history was
available. Seven children had had two operations for this condition, and three
children had had three operations.
The percentage of children with marked enlargement of tonsils was 57,
while 0.65 per cent, in addition showed evidence of adenoids without enlarged
tonsils. The proportion of children with enlarged tonsils is greatest among the
entrants, being 6.6 per cent., and least among the ten years' old group, being
5.1 per cent.
The percentage of mouth breathers was 3.06 among the entrants, 1.23
among the 10 years' old group, and 0.97 among the leavers.
The percentage of children with marked enlarged tonsils has very much
decreased during the course of the last four years. In 1909 it was 10.8, almost
double that for 1913. It is probable that increased attention to proper habits
of breathing among the children will reduce the proportion still more.
Enlarged Glands.
The submaxillary glands were found enlarged in 81 boys (3.6 per cent.)
and 42 girls (2.1 per cent.).
