Abstract

Objective: To explore the relationship between the volumetric bone mineral density (vBMD), the thickness of the condylar cortex (T_cortex) and the hemimandibular volumes (V_hemimandible) of symmetrical and asymmetrical mandibles of children. Design: The data collection consisted of 92 archeological skeletal remains of children's mandibles between 1 and 12 years old. The mandibles were digitalized with a computed tomography (CT) scan, and three dimensional models were obtained. V_hemimandible was calculated using the optimal symmetry plane. The volumes were used to calculate the asymmetry index (AI). Mandibles with an AI of ≥ 3% (N = 9) and a sample of the most symmetrical mandibles (N = 9) were selected for this research. Three groups were created: a symmetrical, an asymmetrical and a pooled group. Micro-CT was used to measure the vBMD and T_cortex in four volumes of interest. The AI was calculated for these parameters as well. Results: Significant correlations were found between the vBMD and the T_cortex in the pooled group (P <.01) and between the AI of the vBMD and the AI of the T_cortex in the pooled (P <.01) and symmetrical group (P <.05). No significant correlations were found between the vBMD and the V_hemimandible and between the respective AIs. Between the T_cortex and the V_hemimandible a significant correlation was found in the pooled and asymmetrical group. Conclusion: There is a relationship between the vBMD and the T_cortex. The correlations between the T_cortex and the V_hemimandible are insufficient to draw firm conclusions. A relationship between the vBMD and V_hemimandible was not confirmed in this study.
