Cephalometric evaluation of the cranial base in the Bulgarian population

Katya Todorova – Plachiyska, Silvia Krasteva, Stefan Zlatev, Stilyana Krasteva


INTRODUCTION: The cranial base is a relatively stable area of the craniofacial region used in many radio­graphic cephalometric analyses. The cephalometric analyses are generally based on the Caucasian cephalo­metric standards and there has been concern about elaborating the cephalometric analysis to be more spe­cific for the Bulgarian patients.

AIM: The aim of the present study was to determine the cephalometric norms of the cranial bases for the Bulgarian population and to compare them to other standards.

MATERIALS AND METHODS: Lateral cephalograms of 90 orthodontically untreated Bulgarian adults with clinically excellent occlusion were evaluated and the anteroposterior skeletal measurements of the cra­nial base were assessed using standard cephalometric analyses. The data were processed with statistical package SPSS 19.0.

RESULTS: Based on gender, we established statistically significant differences. The mean values of cranial base indicators did not differ between subjects of different age in the sample.

CONCLUSION: The mean values for the total sample can be used as cephalometric standards for Bulgar­ians. Cephalometric values identified for Bulgarian subjects are expected to help in the simplification of orthodontic diagnoses.
