I found this today and thought I would share. It's not ALL devoted to chinchillas, but an interesting read with some interesting images. The abstract is below and a link to the article following it.
Malocclusions in guinea pigs, chinchillas and rabbits, Loïc F.J. Legendre
Can Vet J. 2002 May; 43(5): 385–390.
Abstract
The types of malocclusions encountered in rodents and lagomorphs are classified. Diagnosis, treatment, and prognosis are reviewed. Some malocclusions are curable, whereas others can only be controlled. The need to perform a complete oral examination and to find a cause for the condition is stressed, as it will seriously affect the prognosis.
