Background: The skeletal morphology of the temporo-mandibular joint (TMJ) is constantly remodeled. Aims and Objectives: A comparative study was undertaken to determine and characterize the differences in the skeletal morphology of TMJ of children and adults. Materials and Methods: The study was conducted on 30 children cadavers and 30 adult volunteers. Parameters that could reflect TMJ skeletal morphology were measured with a new technology combining helical computed tomography (CT) scan with multi-planar reformation (MPR) imaging. Results: Significant differences between children cadavers and adults were found in the following parameters ( P < 0.05): Condylar axis inclination, smallest area of condylar neck/largest area of condylar process, inclination of anterior slope in inner, middle, and outer one-third of condyle, anteroposterior/mediolateral dimension of condyle, length of anterior slope/posterior slope in inner and middle one-third of condyle, anteroposterior dimension of condyle/glenoid fossa, mediolateral dimension of condyle/glenoid fossa, inclination of anterior slope of glenoid fossa, depth of glenoid fossa, and anteroposterior/mediolateral dimension of glenoid fossa. Conclusion: There are significant differences of TMJ skeletal morphology between children and adults.
