Computed tomography (CT) technology has seen tremendous growth since itsfirst medical applications in the early 1970s. Nowadays, high-spatial-resolutiondigital detectors enable the micro-computed tomography (μCT) technique,which has been introduced to a wide variety of applications, including biomedicalsciences like odontological applications. Endodontic treatments stand asone of the most common dental procedures, and the quality of the treatment isessential to prevent and control any potential infection of root canals. This treatment is typically achieved by careful cleaning, shaping, and sealing steps. Often, endodontic treatments fail due to a poor seal, even if a meticulous root canal preparation is carried out. The present work reports on the spectrometric adaptation of a μCT facility for accurate quantification of root canal sealing with bioceramics, aimed at assessing the sealing performance of the new Bio-C Sealer product. A dedicated irradiation setup along with digital image processing techniques have been developed for the accurate and automatic recognition of dental samples root canal anatomy and bioceramic-based sealers. The performance of the proposed approaches has proved to be qualitatively and quantitatively robust for automatic characterization of the endodontic treatment sealing quality, satisfactorily identifying and segmenting canal root, gutta-percha cone, and bioceramics.
