Indiana University-Purdue University Indianapolis (IUPUI) / The purpose of this study was to determine the
rate of plaque formation in children and its relationship
to their periodontal and caries indices and to
evaluate a television area measurement instrument.
Plaque formation at 6-, 24-, 48-, and 96-hour intervals
was observed in 56 children aged 8 through 12 to
establish the rapidity of its reformation after a thorough
dental prophylaxis. The plaque was recorded with disclosing
agents and oriented Polaroid photographs and
measured by newly developed television and electronic
area measurement instrumentation which proved to be highly
reliable. The presence of caries and periodontal disease
was then correlated with the amount of plaque recorded at
each observation period. A high correlation was found
between the Anterior P-M-A and the Periodontal Index.
No significant correlations were found between the
periodontal indices and the DMFs scores or with the amount
of plaque present and the DMFs scores. Seventy-seven per cent of the children displayed measurable amounts of plaque just 6 hours after a thorough dental prophylaxis. In comparing
the amount of plaque formed by these children with
results reported from similar studies conducted on adults,
it is apparent that children in this age group form more
plaque in less time than adults. A significant correlation
was found between the amount of plaque present and the periodontal indices at the 48-hour examination.
