At the DVR level, it will be more accurate to determine the relationship between the mental foramen and tooth position by observing the long axis direction of the tooth. A1, A2, A3 Right side. B1, B2, B3 Left side. A1, B1 Cross-section in the front-back direction of the DVR. A2, B2 Panoramic image at the DVR. A3, B3 Axial plane of the DVR. A2 White dense image is the bony canal at the tooth apex (green arrow). The mental foramen is observed by moving the observation axis back and forth in the direction of the long axis of the tooth at the DVR level
