Abstract:

OBJECTIVE

The aim of the study is to identify the consistency of expert opinions when manually identifying the reference points positions for studying the soft-tissue face profile in digital teleradiological images of the skull lateral projection.

MATERIAL AND METHODS

The study involved 11 orthodontists having a 1 to 8 year experience. They localized the reference points manually, using the software with image enhancement options. Each doctor processed 100 X-ray images of the skull lateral projection. Totally, 1100 positions were identified (11 parameters in 100 images). The average position of 11 manual localizations was taken as the baseline. Then, manually identified positions were automatically compared with the basic localization.

RESULTS

We have a good consistency of expert opinions when determining the reference points of the soft-tissue face profile. Herewith, the highest consistency of expert opinions is observed for soft-tissue reference points of the upper and lower lips (LL and EN points) with the average variation coefficients equal to 0.557726 and 0.566349 respectively; and the lowest consistency is observed for the hard tissue point Po with the average variation coefficient of 0.819904. Despite rather serious shortcomings in determining separate points (such as Or, DT, Po) in teleradiological images of the lateral skull projection, the method for determining soft-tissue profilometric reference points gives satisfactory results for more than 85.87% cases. In general, the method can be considered clinically reliable. However, the means and methods for identifying reference points require improving.
