Radiographical evaluation of articular eminence inclination and height by cone beam computed tomography in Diyala

Abstract

Background: After compared  to  other  human  joints,  the temporomandibular  joint,  a  synovial  joint  with  complex biaxial movements and has the largest range of motion. It is also identified as a ginglimoartrodial joint. When the jaw is moved the condylar process travels  along  articular  eminence, part of  temporal  bone.  Individual differences occur via the inclination of articular eminence, which controls the direction of condylar movement and the grade of disc rotation over the condyle.
Aims of the study: Radiographical assessment of inclination of eminence and eminence height conferring to gender and location via cone beam computed tomography in Diyala.
Materials  and  methods:  The  study  samples  collected  of  seventy individuals (140 joints) twenty-two male and forty-eight female with age range from (20-55) years old. Inclination of eminence and eminence height were measured in study via cone beam computed tomography. Statistical Analysis, the System-SAS (2018) program was employed to determine how different study parameters affected the various groups. Results: The results show articular eminence inclination and height in sides right and left, males have verified higher mean value than females. The results show inclination of eminence and eminence height in right side have recorded higher mean value than left side with a statistically non-significant relationship. 
Conclusions: Males have a steeper eminence than females. Height of eminence in male are higher than female. .
