Description

High blood pressure is a trait, as opposed to a specific disease, and represents a quantitative rather than a qualitative deviation from the norm. In hypertensive patients nutrient canals are clearly visible and appear more frequently. Radiolucencies that appear to represent spaces in bone through which blood vessels and nerves travel to supply surrounding structures have been termed as nutrient canals. Nutrient canals have also been called inter-dental canals, circulatory canals, vascular channels or inter-dental nutrient canals. Nutrient canals are tube-like conduits seen in the alveolar bone that contain neurovascular elements that supply teeth and supporting structures. These anatomical structures are frequently seen as fine linear, curvilinear, or circular radiolucencies situated within the interproximal alveolar bone or inferior to root apices. Nutrient canals are found throughout the maxillary and mandibular alveolar processes. Nutrient canals appear most frequently on the intraoral radiographs of the mandibular anterior region, followed by the mandibular premolar area, the maxillary premolar area, and the wall of the maxillary sinus.
