AB  - OBJECTIVE: To explore the normal variation of asymmetry in mandibles of children 
      in the age group of 1 to 12 years. MATERIALS AND METHODS: The study group 
      consisted of 92 cadaveric mandibles of children with a dental age of 1 to 
      12 years old in possession of ACTA (Academic Centre for Dentistry Amsterdam), 
      Faculty of Dentistry, the Netherlands. 3D models of the mandibles were obtained 
      from CT-scans and hemimandibular volumes of all mandibles were calculated. The 
      condylar height, ramus height, mandibular body length and the gonial angle were 
      bilaterally determined using a novel landmark-based method, and the degree of 
      asymmetry was calculated. RESULTS: No relationship was found between dental age 
      and asymmetry of the studied parameters (P < .05). The highest degree of 
      asymmetry was found in the ramus height, whereas the gonial angle presented the 
      lowest degree of asymmetry. A positive correlation was found between the 
      asymmetry of the hemimandibular volume vs the height of the ramus (P < .05) and 
      the length of the mandibular body (P < .05). An inverse correlation was found 
      between the asymmetry of the ramus height vs the condylar height (P < .05), 
      mandibular body length (P < .05) and gonial angle (P < .05). CONCLUSIONS: 
      Mandibular asymmetries in children did occur (9.8% of the included mandibles 
      presented with a relevant overall asymmetry of >/=3%) and were unrelated to age. 
      The different segments of the mandible seem to compensate for each other, in 
      order to maintain a functional equilibrium.
