In a pre-clinical study conducted at the University of Queensland School of Dentistry and published in ACS Publications, Dr Chun Xu and his team are working on a nanotechnology-based method to alleviate tooth sensitivity, one of the most common oral problems affecting 74% of the population.
Several methods already exist to mitigate and prevent the pain caused by tooth sensitivity, but this study could provide a solution that is as effective in the short term as it is in the long term.
How does nanotechnology work in the dental sector?
“When tooth enamel is worn away and the dentine is exposed, eating or drinking something cold or hot can cause sudden, sharp pain. With the nanomaterials used in this study, the exposed dentine tubules can be quickly blocked and the pain prevented,” explains Dr Xu.
The solution proposed in the study is innovative because it does not just mitigate pain instantly, but effectively and durably in the long term compared to other tooth sensitivity treatments and it would be extremely simple to use: “The materials could be developed into a toothpaste and people with sensitive teeth would simply apply the toothpaste to the tooth and massage it for one to three minutes,” says the doctor.
Nanotechnology: present and future of dentistry
This is not the first time that nanotechnology has been proven to be effective in dental treatment. Since the introduction of nanocomposite resins, scientists have been looking for ways for dentists to use this technology safely in the dental practice.
Dr Xu is hopeful that, if successful in clinical trials, his study will inspire other doctors and researchers to use nanotechnology to help address today’s dental needs.
