Mandible Thickness in the Pediatric Population: A Pilot Normative Anthropometric Estimation Using CT Images

Introduction The mandible's morphology in Indian pediatric patients, shaped by genetic, environmental, and functional factors, is critical for diagnosing anomalies and planning surgical interventions, especially implant placement. However, there is scarce morphometric data on mandibular bone thickness in Indian children, coupled with the reliance on adult-focused studies and outdated imaging, which underscores the need for precise evaluation. This study aimed to address these gaps related to the topic Methodology We sought to assess normative anthropometric data from CT scans of 29 patients aged 2-16 years, sourced from a tertiary care hospital's database. Using a retrospective approach, the mandible was classified into anterior and posterior segments, with full and cortical thicknesses measured at nine key points. Results Our findings revealed no significant bilateral differences. Maximum full and cortical thicknesses were observed at point 7 (upper one-third, distal-most body region). At the same time, minimum values were at point 3 (lower one-third, symphysis-parasymphysis) for full thickness and point 1 (upper one-third, symphysis-parasymphysis) for cortical thickness.  Conclusions This study provides normative mandibular thickness data for Indian children, offering a foundation for global mandibular assessment across ages and genders, thereby enhancing the safety and efficacy of dental and surgical interventions.
