Phase I

Contract Number: 2025911
Start Date: 9/1/2020    Completed: 2/28/2021
Phase I year
2020
Phase I Amount
$256,000
The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase I project is to improve dental care and cavity prevention. Oral health maladies have been referred to by the Surgeon General as America?s silent epidemic, and caries disease (tooth decay) is the single largest disease in the world. Current care models are failing because they reactively focus on treatment instead of prevention, although acidity is recognized as the driving factor behind tooth decay. High-risk patients often spend over $10,000 annually, with the highest-risk patients experiencing bills of over $100,000 for comprehensive dental care. This project will advance an Internet-of-Things (IoT) technology to measure mouth conditions for preventive dental care. The proposed sensor will continually measure and transmit real-time oral pH data to a mobile application on the user?s smartphone. Dentists will also have access to long-term patient data at checkups. The technology will mitigate or eliminate expensive cavity-related health complications, which may be beneficial for disadvantaged and high-risk patients. In the longer term, saliva can be used as a non-invasive way to detect a range of biomarkers, such as proteins, electrolytes, hormones, antibodies, DNA, as well as therapeutic drugs or allergens. The proposed technology will enable the collection of new amounts of health-related data.This Small Business Innovation Research (SBIR) Phase I Project aims to develop a novel, intraoral IoT sensor for dental caries preventive care. When prolonged periods of unhealthy pH levels are identified, the user will be provided with a specific product recommendation to effectively prevent the progression of dental caries. The objectives of the proposed Phase I project are to fully miniaturize the electronic system (power supply, CPU, bluetooth antenna, signal conditioning) to comfortably fit around one molar, and minimize both signal drift and biofouling impacts on the ion sensitive field effect transistor pH sensor such that a reliable signal can be produced continually for one week without calibration.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

Phase II

Contract Number: 2151368

Phase II year

Phase II Amount
$1,000,000
The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase II project is to manage the risk of tooth decay, or caries disease, the world’s most prevalent chronic condition. Tooth decay results in severe pain, devastating financial issues, lost work, loss of confidence, embarrassment from appearance and speech, and broad systemic health problems. It disproportionately affects minorities and lower-income individuals. Controlling acid levels of high-risk patients is an effective decay prevention strategy. An oral acidity monitor for caries prevention will allow patients at high risk of caries disease to receive alerts to neutralize intraoral acidity before it causes permanent damage, and work more effectively with their dentists to follow and evaluate the effectiveness of prescribed caries prevention protocols. This Small Business Innovation Research (SBIR) Phase II project focuses on the commercialization of the world’s first continuous intraoral acidity monitor. This project advances sensors providing long-term data readings of salivary pH and its response to environmental conditions. As a platform technology, intraoral sensors have more applications in a broad range of markets in addition to dental caries; future sensors include sodium and potassium monitors for heart disease, hypertension, and renal failure, and glucose monitors for diabetes. Long-term plans include biologic sensing such as allergen, viral load, and drug compliance monitors.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
