Evaluation of the correlations between the cephalo- and somatometric parameters and parameters of teleroentgenograms of the head in boys and girls of the Omsk city

Abstract

The aim of the study was to identify correlations between the cephalo- and somatometric parameters and parameters of teleroentgenograms of the head (in the lateral projection) to assess their influence on the face shape. Material and methods. An anthropometric study of the head and body was carried out in 70 boys and 70 girls. To obtain teleroentgenograms of the head in the lateral projection, 39 boys and 39 girls (out of those examined, based on their informed consent) underwent an X-ray examination using a Planmeca ProMax 3D CT scanner (Finland). Cephalometric analysis of the obtained images was carried out using the Mave Cloud online service. Quantitative data were statistically processed using Statistica 6.0 program. Results. Gender differences in values (p<0,05) were detected for the following parameters: length of the anterior skull base according to Bjork, anterior face height, length of the body of the lower jaw according to Jarabac, height of the lower jaw branch, length of the posterior skull base, posterior face height, length of the anterior skull base according to Schwarz, lengths of the lower jaw, length of the upper jaw, thickness of soft tissues in the chin area on the segments Me-me, Gn-gn, Pog-pg. A direct moderate relationship was found between the values of the intermaxillary angle and zygomatic diameter, on the one hand, and the face shape, on the other hand (p<0,05). Conclusion. A number of linear parameters of lateral teleroentgenograms have gender and regional features. In addition, teleroentgenograms and somatotype parameters affect the face shape; this fact has to be considered when correcting occlusion and facial aesthetics in the dental practice.
