This study employs the three-dimensional visualization capability of cone-beam computed tomography (CBCT) to investigate the relationship between chronological age and timing of fusion of the spheno-occipital synchondrosis in a male/female subadult Hispanic population of Southern Nevada. The sample includes cross-sectional data of 374 orthodontic patients (166 males and 208 females) aged 8-20 years. The SOS is scored by a four-stage scoring system as completely open (stage 0), less than half fused (stage 1), more than half fused (stage 2), or completely fused (stage 3) as visualized in the midsagittal plane in the CBCT image. The relationship between SOS fusion stage …
