Abstract
The purpose of this study is to test whether measurements made from
an intraoral radiograph and applied to formula can accurately measure
square millimeters of attachment apparatus encasing a tooth. Two samples
of 15 and 22 alveoli were radiographed and the amount of attachment calculated
by formula. Rubber base impressions of these alveoli were made
and coated with wax. The coatings were carefully removed, and their outlines
traced on millimeter graph paper. Thus, square millimeters of
attachment were determined by direct measurement. Differences between
the pairs of measurements were tested. The results show that the formula
can accurately measure attachment apparatus. The relationship between
one and two dimensional estimations of bone loss and the implications of
the study are discussed.
