The mode of tooth attachment in the black bass was observed by scanning electron microscopy, stereoscopic microscopy and light microscopy.
The black bass had conical teeth on the lower and upper jaws and these teeth had a hinged attachment. The form of attachment between the basal dentin and the pedicle differed between the anterior hinge and the posterior hinge. In the anterior hinge the front portion of the basal dentin was free from the pedicle, which was thickened and rounded like a buttress of bone. However, in the inner part of the anterior hinge and in the posterior hinge, the fibers of the basal dentin were continuous with the pedicle.
The fibers of the anterior and the posterior hinge were collagenous, but the degree of contraction differed between the lingual and pulpal sides of the posterior hinge. These differences in the structure of the hinged attachment were adapted to its function.
