The
primary aim of this investigation was to establish
standards for some commonly used clinical cephalometric
measurements from twelve year old Cardiff girls,
which could be used for a South Wales population,
or even on a wider basis. The findings were based
on lateral cephalometric radiographs, height and
weight measurements and a questionaire. The sample
was randomly selected from all twelve year old
girls living in Cardiff during 1968. The findings
for the sample of 216 girls indicated a considerable
range of variation of many of the cephalometric
variables. This variation is statistically described
by the ranges and standard deviations of all the
continuous variables and illustrated with histograms.
Though it would be tempting to make comparisons
of the findings of this study with those of other
workers, it is felt that they would be misleading.
The purpose of this study has been to emphasise
the need to employ sampling techniques which reduce
the number of variables such as that of age and
sex race, and which assure that the sample is
fully representative of the community.
