METHODOLOGY
A study of prevalence of dental caries of school
going children of Swat was undertaken, to evaluate
prevalence of dental caries in relation to various risk
factors.
This survey was carried out in different schools on
646 children living in Swat – Pakistan. These different
schools were randomly selected. The sample consisted
of 231, 358, and 57 children in the 3-5, 6-8 and 9-12 years
of age group, respectively. In each of these age groups
an attempt was made to include equal number of male
and female subjects but it was not possible because of
the fact that girls are usually neglected regarding
sending to schools in such areas of Pakistan that’s why
male to female ratio was approximately 4:1 respectively.
Consent for examining of the children was obtained
from the respective District Health Officer and District
Education Officer along with the Principal of the schools
in sample. All the children present on the day of
examination were included in the study and only
uncooperative children were excluded from it.
A separate proforma for each child was used and
after entering basic demographic information and oral
hygiene habits, child was examined in ordinary chair
