Objective:To investigate the relationship among the congenital hypodontia of mandibular incisor and malocclusion and the variation of medial distal dimension of mandibular canine.
He says such culinary adaptations resulted in fundamental changes in craniofacial growth and development, resulting in reduced robustness, increased malocclusion and increased tooth crowding.
This is very striking considering according to Proffit's 1994 Contemporary Orthodontics, two-thirds of the US population has some degree of malocclusion — misalignment of the teeth.
