Resumen
Descripción general del contenido del recurso.
Craniofacial modifications, which come about with aging, are usually attributed to tooth loss, and it is accepted that other skull structures remain unchanged. The purpose of the study was to analyze morphological changes in different craniofacial components. The hypothesis to be tested states that once adulthood is reached, craniofacial changes are localised and only associated with tooth loss. Neural and facial measurements were taken on 70 French individuals aged between 22 and 102 years. Dental state was assessed and individuals were divided into three categories: total absence of tooth (ATD), partial absence of tooth (APD) and complete dentition (DC). Principal Components Analyses and ANCOVA were carried out to evaluate morphological change related to age and dental state. The results indicated that there was a decrease of craniofacial size in all the measurements including those that described structures that were unrelated to dental support although older individuals showed also a remarkable tooth loss. When age was adjusted, the only reductions associated with dental state were found in alveolar width and length, masticatory width and facial height. Although this pattern of variation could be related to tooth loss, it may depend on several biological changes with aging. Tooth loss and aging are two linked biologica processes since individuals that lack tooth completely may present accumulative changes with age because the reduced number of tooth influences on the kind of nutrition and, thus, on the craniofacial complex. Therefore, the stated hypothesis was rejected.
