Treatment
In 1971, 3777 school children received treatment. Of those commencing a course of treatment,
72% completed the course. The pattern of treatment provided can be indicated by the
ratio of teeth filled to extracted, which was 22:1 in permanent dentition. Of permanent teeth
extracted .38% were removed for reasons of orthodontic treatment. In the deciduous dentition the
ration was 3.0:1. It was necessary to fit only 3 dentures. The fact that the greater number of
extractions is undertaken for 5—9 age group indicated the poor state of children's teeth on entry
to schools, a condition which could be resolved by fluoridation of water supplies.
In the specialised field of orthodontics, 55 removable appliances were fitted and 5 fixed.
The demand for this type of treatment is rapidly increasing. It was necessary to increase
orthodontic sessions to 2 a week, which was undertaken by a Senior Dental Officer who has
specialist qualification in this field.
General anaesthetics were administered by general medical practitioners.
Dental Decay Prevention and Health Education
The most effective prevention is obtained through chairside instruction in the routine of
oral hygiene. This is undertaken by Dental Officers and Auxiliaries for their patients.

Dental Health kits containing a plastic beaker, a tube of toothpaste and a toothbrush were
distributed to 1,088 new entrants and to 90 children in Play Groups. Towards the latter part
of the year talks were extended to include expectant mothers and children in play groups, as
it was felt that information should be given as early as possible.
Maternity & Child Welfare
Treatment for this priority group is not offered at particular sessions but is integrated with
other children's treatment in order to provide full "Family care".
Approximately 7% of dental services is given to this group. The pattern of treatment provided
is increasingly orientated towards preservation, as is indicated by the ratio of extractions to
