Ergonomics and ease of visualization play a major role in the effectiveness of endodontic therapy. Using only commercial off-the-shelf components, we present the pulpascope-a prototype of a compact, handheld, wireless dental instrument for pulp cavity imaging. This instrument addresses the current limitations of occupational injuries, size, and cost that exist with current endodontic microscopes used for root canal procedures. Utilizing a 15,000 coherent, imaging fiber bundle along with an integrated illumination source and wireless CMOS sensor, we demonstrate images of various teeth with resolution of ∼48 μm and angular field-of-view of 70 deg.
