This study was designed to find the most reliable method of measurement of mesiodistal tooth diameter.
Measurements were made of all erupted permanent teeth of 14 orthodontic study casts. These measurements were made directly by
using A) a digital calliper, B) measuring photocopies of casts with a calliper, C) a Magiscan Image Analysis using a photocopy of the
casts. Measurements derived from the two methods were compared by statistical analysis.
These showed that the electronic
digital calliper was the most reliable method of measuring mesiodistal tooth diameter using dental study casts. The measurement of
photocopies was unreliable and the image analysis method had a too high error factor.
