Age estimation in an Indian subpopulation by cone-beam computed tomographic analysis of spheno-occipital synchondrosis fusion
Age estimation has been an ever-evolving aspect of forensic science. There is no dearth of markers in estimating age around 14–15 years; however, there is paucity for adolescent- adult transition markers. Various studies have cited the late closure of spheno-occipital synchondrosis (SOS). This study...

Age estimation has been an ever-evolving aspect of forensic science. There is no dearth of markers in estimating age around 14–15 years; however, there is paucity for adolescent- adult transition markers. Various studies have cited the late closure of spheno-occipital synchondrosis (SOS). This study is an attempt at ascertaining the possibility of age estimation in an Indian subpopulation by cone-beam computed tomographic (CBCT) analysis of SOS.271 (145 males, 126 females; 10–25 years) full volume scans were assessed on the Planmeca Promax, 3D-mid CBCT unit.
