Evaluation of the relationship between the Sella Turcica size and the vertical skeletal growth pattern of the face in Cone Beam Computed Tomography images in an Iranian population

Abstract

Introduction sella turcica is one of the most important orthodontic landmarks and a key point in lateral cephalometric analysis of the patients who need orthodontic treatment. The aim of this research was to investigate the relationship between the dimensions of sella turcica with the vertical skeletal pattern of the face in cone-ray computed tomography images in an Iranian population. Materials and methods In this descriptive-analytical research, the samples were evaluated in a total of all available CBCTs of the patients referred to Tabriz Dentistry Faculty. In the selected CBCT (in sagittal sections), the length and height of sella turcica was measured. By evaluating the angle between the two lines Go-Me and S-N as well as the S-Go / N-Me ratio, the short, long or normal facial skeleton was examined. The data obtained from CBCT were entered in NNT viewer version 2.17 and the images were reviewed by two oral and maxillofacial radiologists and the agreement between the two observer results was measured by Kappa coefficient. Data were analyzed by SPSS 20 software and Kruskal-Wallis statistical test. Results The length and height of sella turcica were similar in the three types of vertical face growth (normal, long and short). In each of the types of vertical facial growth (normal, long and short), the height and length of Salatorsica were similar in men and women. In each type of vertical growth of face, height and length of Salatorsica had no significant relationship with age. Conclusion The length and height of sella turcica were similar in the three types of vertical, normal, long and short growth.
