Recent Advances in Dentistry Focus on Detecting Cavities and Tooth Sensitivity
Two recent technological advances in dentistry will help dentists provide better treatments and care for their patients, which were the result of separate research programs being conducted at York University in Toronto and the University of Toronto.

Earlier Cavity Detection (York University in Toronto)

The York University program focuses on developing new imaging solutions to help dentists detect cavities sooner. Tooth decay is the underlying cause for cavities in children and adults and is the leading complaint among patients.

The current detection process involves the dentist performing a visual inspection of the teeth to look for signs of tooth decay. However, visual inspections alone are not sufficient for discovering tooth decay, so the dentist also takes a series of x-rays to help find dental decay within the tooth structures.

The primary drawback with current detection methods is they are not effective until after the cavity has started to form within the tooth. Using the newly developed imaging method invented at York University, it is conceivably possible to detect tooth decay as soon as it starts to form on the actual exterior surface of the teeth, long before it eats away the protective enamel and infects the interior of the tooth structure.

The research team at York University invented a TPLI (Thermophotonic Lock-in Imaging) tool which incorporates an infrared camera and the use of long wavelengths to help detect tooth decay on the tooth surface at an early stage.

The research team conducted tests on actual teeth, which had been extracted from patients for various reasons. By exposing the teeth to an artificial form of tooth decay, they could see results of tooth decay on the tooth’s surface in as little as two days. While the research is only in the nascent stage, it is expected it will help pave the way for developing the technology further and eventually lead to actual use by dentists in the near future.

Nanotechnology and Tooth Sensitivity (University of Toronto)

Researchers at the University of Toronto recently developed and released a new product to address tooth sensitivity, a dental issue the vast majority of the population experience at some point during their lives. For some people, it is an ongoing issue that makes eating, drinking, and having dental procedures performed rather challenging.

Using nanotechnology, the team invented what they call BioSchell, which is a nanoparticle polymer that is also bioactive and naturally derived. The nanoparticles within the gel create a protective layer over the surface of sensitive teeth. Once applied to the teeth, the sensitivity experienced by the individual is greatly reduced or completely stops.

The creation of BioSchell has significance within the dental industry. Not only does it provide a viable solution for sensitivity problems, but is also considered the newest generation of solutions utilizing advanced technologies to provide better dental health treatments.

The new product created by the team of researchers is called UNO Gel, which is being produced and distributed by Germiphene Corporation, in conjunction with startup company, Oral Antibacterials, Inc.
