Fig. 1. MicroCT analysis of symphyseal (A) and TMJ (B) structure in rabbits. (A) Tracing of a coronal section of the middle joint site. In each of five coronal sections, biomineralization levels were evaluated with computer assisted image analysis at five equidistant points along the articular surface (arrows) and four equidistant points along the lateral, superior and inferior cortical bone regions (arrowheads). Symphysis height and width also were quantified (not shown). (B) Tracing of the coronal section of the middle condylar site. In each of three coronal sections, bone-density levels were evaluated with computer-assisted image analysis at five equidistant points along the articular surface (arrowheads), four equidistant subchondral bone locations below the condylar articular cartilage (circles) and three equidistant points along each side of the condylar neck below the articular surface (arrows).
