The versions of Tables 3 through 7 in the original paper are not compatable with web presentation. They have been re-set and appear under a separate heading. Then the patterns of change in the dental health of adolescents between 1988-1994 are examined and summarized. Lastly summary tables present key data from the last 10 years of survey results grouped by variable.
Sufficient data is now available to examine changes in epidemiological measures through time.
Complete records of d3mft and its components are available for 133 health districts in England, all 9 districts in Wales and all 15 health boards in Scotland. The skewedness of the d3t, ft and d3mft data was corrected by square root transformation. The percentage data was expressed as proportion and the square root of each value was arcsine transformed. However, the change has not been directional, and the proportion of children with disease appears to have remained constant. Beneath this overall uniformity, changes in the make-up of the disease have occurred.
