Mandibular symphysis height based on gender in cephalometric radiographs

Cephalometric radiography is an examination method that often used in orthodontic treatment to make a diagnosis which includes the relationship of teeth to jaw, assessment of skeletal relationships, assessment of dental relationships and functional analysis. This study aims to determine the height of the mandibular symphysis through cephalometric radiographic based on gender. This study aims to determine the height of the mandibular symphysis by gender from cephalometric radiographic picture. This research is using analytic observational design. The research data used 70 secondary data cephalometric radiograph of RSKGMP Airlangga University patients. The data was measured manually by forming a line parallel and perpendicular to the line tangent to point B, and calculating the distance between the superior border of the mandibular symphysis taken at point B to the most inferior border of the symphysis outline. The average value of the mandibular symphysis height in males is 22.44 mm and in females is 20.53 mm. There is a significant difference in the height of the mandibular symphysis in males and females.
