Opportunity Summary:

The funding opportunity PA 15 335, titled "Imaging Diagnostics of Dental Diseases and Conditions (Caries, Periodontal Disease, Cracked Teeth, and Pulp Vitality) (R43/R44)," is a Small Business Innovation Research (SBIR) grant program from the National Institutes of Health (NIH). Its central goal is to push forward the advanced development and real-world clinical adoption of imaging-based diagnostic devices that can detect and assess common dental diseases and conditions more accurately than the tools most clinicians rely on today. The focus is on four major targets: dental caries, periodontal disease, cracked teeth, and pulp vitality. The program emphasizes that proposed technologies should be reliable and reproducible, and they must achieve very high specificity and sensitivity, meaning they should correctly identify disease when it is present and avoid false alarms when it is not.

A key expectation is that these imaging diagnostics should show clear performance advantages over current standard methods, particularly the usual visual and tactile examination and traditional radiographic approaches used for caries detection. Importantly, better performance cannot come at the cost of increased risk to patients. In practical terms, applicants are being pushed to deliver diagnostics that improve clinical decision-making without adding avoidable harms, such as unnecessary radiation exposure, excessive heat, or other safety concerns that might arise from some energy-based imaging systems.

The announcement highlights a range of technical approaches that applicants may explore. These include optical coherence tomography (OCT), either alone or combined with Raman spectroscopy, as well as MRI image analysis techniques. It also calls out several device and signal-based methods that can be used to infer tissue condition, such as electrical conductivity measurement (ECM), quantitative laser fluorescence (QLF), alternating current impedance spectroscopy, multiphoton imaging, infrared thermography, infrared fluorescence, ultrasound, and terahertz imaging. While these examples illustrate the kinds of platforms NIH considers relevant, the opportunity explicitly welcomes the development of entirely new imaging modalities, signaling that novel physics, new contrast mechanisms, new combinations of modalities, and improved computational interpretation methods are all within scope as long as they address the clinical needs.

Administratively, this is a discretionary grant mechanism under the SBIR R43/R44 pathway, which generally maps to phased small business development (commonly understood as early feasibility and development work followed by more advanced development and steps toward commercialization and implementation). The funding opportunity is associated with CFDA numbers 93.121 (Oral Diseases and Disorders Research) and 93.286 (Discovery and Applied Research for Technological Innovations to Improve Human Health). There is no cost sharing or matching requirement, which matters for small businesses that may not have the ability or desire to commit non-federal dollars as a condition of award.

Eligibility is limited to small businesses. Foreign (non-U.S.) organizations are not eligible to apply, and non-U.S. components of U.S. organizations are also not eligible. However, "foreign components" as defined by the NIH Grants Policy Statement may be allowed in some cases, which typically means a U.S.-based applicant might be able to include certain specific foreign activities or collaborations if they are well-justified and compliant with NIH policy.

The opportunity was posted and created on August 20, 2015, with an original and current closing date of September 7, 2018, and an archive date of October 8, 2018, indicating that this specific announcement is no longer open for applications. The official announcement and details were hosted by NIH at the provided link (grants.nih.gov), and NIH’s Office of Extramural Research (OER) webmaster contact was listed for technical access or linking issues.
