Panoramic Radiographic Analysis of Age- and Sex-related Variations in Upper Mandibular Morphology: Focus on the Condyle, Sigmoid Notch, and Coronoid Process.

Abstract

Background/aim: This study aimed to investigate age- and sex-related morphological variations of the mandibular condyle, sigmoid notch, and coronoid process in a mid-sized German population using panoramic radiographs.

Patients and methods: A total of 150 participants (89 males, 61 females) aged between 18 and 80 years were included. Participants were divided by age and sex. Panoramic radiographs were obtained, and the right and left condylar processes, sigmoid notches, and coronoid processes were evaluated for shape variations.

Results: Age-related differences were found in the mandibular condyles, with younger individuals exhibiting round-shaped condyles more frequently, while older participants showed a higher prevalence of flat-shaped condyles (p<0.001). Sex-related differences included females displaying more diamond-shaped condyles (p=0.033) and triangular-shaped coronoid processes (p=0.004), whereas males exhibited more round condylar processes.

Conclusion: This study highlights significant age- and sex-related morphological variations in the mandibular condyles, sigmoid notches, and coronoid processes. These findings have important clinical implications for the diagnosis and treatment of temporomandibular joint disorders and maxillofacial surgery. Understanding these variations can improve diagnostic accuracy and surgical outcomes in patient-specific care.
