Maldevelopment of the cranio-facial-respiratory complex: A Darwinian perspective

Authors:

ABSTRACT

Aim

The mammalian Cranio-Facial-Respiratory Complex (CFRC) comprises several different biological tissues that collectively function under coordination from the central nervous and cardiorespiratory systems, primarily to breathe, eat and drink as well as integrating the sensory and motor systems for speech, communication and protective mechanisms. Anthropologists have long recognised that lifelong exposure to modern feeding regimens of readily available and highly processed foods, changes in breastfeeding and weaning, can impact expression of various phenotypic traits affecting the CFRC quite differently than does lifelong exposure to more traditional ancestral feeding regimens, typical of hunter-gather/foraging in non-Western-exposed cultures. The aim of this study is to highlight the role of the paediatric dentist in a multidisciplinary approach in which professionals working in and around the CFRC can actively prevent tooth decay and skeletal-dental malocclusion in the light of evolutionary oral medicine.

Results

As a result of changes in the environment, in the food quality, in eating and feeding practices starting from day one, two oral diseases of civilisation, tooth decay and skeletal-dental malocclusion, have both relatively recently reached worldwide epidemic proportions and afflict people of all ages.

Conclusion

A multidisciplinary approach in which professionals working in and around the CFRC can actively promote prevention or reversal of dento-skeletal and myofunctional disorders, diagnose them when present and coordinate the appropriate therapy and life long maintenance programme.
