Image Relationship of nasolacrimal duct with apex of large upper incisor (labelled)
This skull is from a wild rabbit. Part of the bony canal that encloses the nasolacrimal duct has been removed to expose the duct within it. The duct bends medially at the apex of the large upper incisor. Only a small amount of apical elongation would compress the duct at that point.

Image text/texmacs Occlusal surfaces of the mandibular cheek teeth
This photograph shows a hemimandible from a wild rabbit. The hemimandible has been tipped slightly to show the regular points that are present on the lingual aspect of the lower cheek teeth. These are normal. They don't need to be removed although they will quickly grow back in a rabbit with healthy cheek teeth. The points are different from the lingually directed spurs that develop on pathologically curved teeth.

Image Transverse section through the skull (labelled)
This skull has been sectioned at the level of the premolars. It shows the position of the nasolacrimal duct (NLD) and the relationship of the apex of the first upper cheek tooth with the maxillary sinus. It also shows the normal occlusal relationship of the cheek teeth with the lingual edges of the maxillary teeth resting against the buccal edges of the mandibular teeth.

Image D source code Annotated skull showing features of PSADD
This skull shows many of the changes that take place during PSADD. The white arrows point to elongated apices of the cheek teeth. The blue arrows point to deformed sections of bone over curve roots of the teeth. The turquois arrow points to a poorly enamelled tooth with ridges on its surface, The green arrows point to loss of alveolar bone supporting the teeth. The yellow arrow points to translucent bone. The black arrow points to gaps where crowns have broken off some teeth and the red arrows points to deformed bone over distension of the maxillary sinus caused by onstruction of the nasolacrimal duct.

Image Mandible of rabbit with spurs on cheek teeth
This mandible of a rabbit with spurs on the cheek teeth shows the change in shape of the teeth and surrounding jaw. The bone is transparent. The teeth are curved along their entire length and the shape of the jaw has changed accordingly. The exposed crowns of the teeth are curved, rather than elongated, which is why the dental spurs are present. Apical elongation is evident and has resulted in swellings along the ventral border of the jaw. These changes are irreversible and cannot be cured by dentistry. Treatment can only be palliative rather than curative.

Image Skull of a rabbit with very advanced dental disease
This skull shows the change that take place in the teeth and bones of rabbits in the end stages of the progressive syndrome of acquired dental disease (PSADD). The crowns of the teeth have either broken of or are disintegrating. The apices of the teeth are long and the bone is very thin. A more detailed description of the changes can be seen on a copy of this image that has arrows on it to highlight the changes..
