The mesiodistal diameters of teeth till 1st molar
on both sides were measured individually from
mesial contact point to the distal contact point at
the greatest interproximal distance. The
individual tooth diameters calculated above
were summed to derive the anterior (canine to
canine), and overall (1st molar to 1st molar)
arch segment values. Overall and anterior
Bolton ratios were calculated according to the
equation .To determine the errors associated
with measurements, 50 dental casts were
selected randomly.
Their measurements were repeated 1 week
after the first measurements. A paired t test was
applied to the first and second measurements.
All statistical analyses were performed with a
software package (Statistical Package for
Social Sciences, Windows 98, version 10.0,
SPSS, Chicago, Ill). For each variable, mean,
standard deviation, minimum, and maximum
values were calculated separately for men and
women.
Table-1 describes the t-statistics. Statistical analysis of these results showed
no significant difference between the Punjabi male and female OR and AR
