Did you know that dental health plays a vital role in your twins’ overall health?
Dental problems amongst children, such as toothache, can interfere with eating, sleeping and exercise and can result in them missing school, impacting academic performance.
Nearly half of all 5-6-year-olds now have a history of dental decay affecting their primary teeth. Similarly, nearly half of all 12-year-olds have a history of decay in their permanent teeth.
Researchers are seeking to better understand dental development – and how it impacts our health. Particularly exciting is a world-leading study by the School of Dentistry at the University of South Australia that involves twins and their families.
This study, Teeth Emergence and Oral Health in Twins and Their Families, is looking at the genetic and environmental factors in dental and craniofacial development (the bones of the face and skull). It has made a number of important discoveries including:
Next, the researchers are looking further at oral microbes, or our mouth ‘flora’, to better understand whether oral health and dental decay are influenced more by genetic or environmental factors. Meanwhile, an overseas study has identified several genes that influence specific aspects of dental health such as teeth alignment.
These exciting discoveries are assisting clinicians such as dentists and orthodontists in prevention, early intervention, and treatment of dental and craniofacial problems.
