treatment for the pre-school child. In the case of boys 70 per
cent. were referred, and in the case of girls, 71 per cent.
Summary of work done at Selhurst Clinic.
During the dental inspection a survey of the incidence of
malocclusion was made for the second time, and out of 18,316
children examined 913 were found to be suffering from irregularity
of the teeth and malformation of the jaws, i.e, 5.0 per cent.,
which compared with 3.7 per cent. at the previous survey, represents
an increase of 1.3 per cent.
Treatment.
The total number of children treated during the past year
was 0,899, compared with 7,110 in the previous year; the aggregate
of treatment sessions was 1,179, as against 1,148 in 1935,
an increase of 31. The total number of fillings in permanent
teeth was 6,254, which is an increase of 542 on last year's total,
and fillings in temporary teeth numbered 399, as against 330 in
1935.
The number of fillings per 100 children treated was 90 in
1930, compared with 78 in 1935. These figures should be contrasted
with those of 1930, when the number of fillings was 32
per 100 children treated. This shows a welcome advance by
parents towards appreciation of conservative measures for their
children's teeth.
In connection with conservative treatment there is a large
amount of work done by means of dressings in teeth, which
totalled 3,542. In this total is included zinc oxide dressings,
capping of exposed nerves, temporary cement fillings, root dressings,
scalings and gum treatments; and in addition 34 dressings
were inserted in temporary teeth and 42 applications of silver
nitrate were made.
Special Treatments.
These included 47 root fillings in anterior teeth, extirpation
of 12 nerves under local anæsthesia, and three under nitrous
oxide; also three cases of fraenectomv. Four stainless steel
partial dentures for children were fitted. These dentures were
inserted in the mouths of children of over 13 years of age who
had lost their front teeth through injuries or caries. In addition,
two vulcanite dentures were fitted.
