Novel Detection Method for Monitoring of Dental Caries Using Single Digital Subtraction Radiography

摘要

This study suggested a novel detection method for monitoring of dental caries based on pixel gray values in digital subtraction radiography images from single dental images of patient's with dental caries. The advantage of single digital subtraction radiography (SDSR) is knowing the status of current teeth with caries without requiring a second digital radiograph. Digital subtraction is currently used in radiographic studies of periapical lesions or other dental disorders that have been treated and whose progress must be evaluated over time. SDSR is a novel detection method for caries that detects dental mass changes from only one dental radiograph. Subjects were chosen among patients who were diagnosed with dental caries from an intraoral X-ray system, we study marks the points of emphasis in hidden dental caries in dental X-ray images from 11 subjects. For each caries lesion that was diagnosed, a mean pixel value was obtained from a SDSR using a scale ranging from 0 to 255 gray values. The image mean variable of the tooth was 71.99 (± 25.64) and 3.25 (± 0.85) (P < 0.0001) for caries and healthy tissue, respectively. SDSR was found to be a novel detection method that uses single dental images of patients to mark the points of emphasis in hidden dental caries.
