''Other Operations" for the year, which include a large amount
of conservative work, stand at 4,675 compared with 4,061. This
figure includes some 18,000 Zinc Oxide Dressings, 520 additional
dressings in temporary teeth, 310 applications of Silver Nitrate,

Gingivectomy, 3.
Removal of Bone Sequestra, 1.
Porcelain Crowns for Anterior tooth, 1.
Splints for fractured incisors, 2.
Minor operations on gums, tongue and fraenum, treatment

26 vulcanite dentures were inserted to replace teeth lost
by caries or traumatic injury.
Extraction of Teeth.
The number of permanent teeth removed for caries and Orthodontic
reasons was 3,003 compared with 2,946 in 1937. The
removal of temporary teeth was slightly lower than last year at
11,495 compared with 12,025.
Local anaesthesia was used on 3,688 occasions against 3,570 in
1937, for extraction of teeth and preparation of sensitive cavities.
Nitrous Oxide was administered on 2,668 occasions as compared
with 2,640.
At Lodge Road Treatment Centre "gas" is administered by
the dental surgeons who devoted 118 sessions to this work. At
the Selhurst and Waddon Clinics the administration is performed
by medical officers and 85 sessions were set apart for this purpose.
Special Cases.
The number of Special forms issued by Head Teachers was
2,379 compared with 2,384 in 1937. This figure, however, does not
include the large number of written requests for treatment that
are received at the Clinics daily.
It is regrettable that this form of treatment is of such dimensions
that routine appointments are considerably interfered with.
Until, however, it is possible to provide each child with a complete
annual treatment, no reduction can be expected.
