Three-dimensional volumetric analysis of mandibular condyle changes in growing subjects: A retrospective cross-sectional study
2018
ABSTRACTObjective: The purpose of this study is to analyze the mandibular condylar volumein a sample of subjects 11–26 years old.Methods: CBCT condylescans from 94 patients (mean age 18.2 ± 4.5 y) acquired with areconstructed layer thickness of 0.5 mm and a 512×512 matrix were examined. Data on condylar volume were compared among three groups with different age ranges: 11–16 years, 17–21years, and 22–26 years. Condylar volumetric measurements were performed with Mimics™ software.Results: A significant increase in condylar volume from puberty to young adulthood was detected (p < 0.01). Females showed a higher condylar volume in the 17–21 y group compared with the 11–16 y group. Males showed differences among all three groups.Conclusion: The mandibular condyle growth seems to continue at least until 17–21 years in males but seems to stop before 17 years in females.
