Rodent and Lagomorph Tooth Extractions, Loïc Legendre, DVM, JVD
What are the two ends of this instrument used for?
Incisor luxation for rabbits and rodents. The more curved end is better for the more pronounced curvature of the maxillary incisor teeth. The less curved end is better suiteed to the mandibular incisor teeth.

Curved end= labial and palatal surfaces
straight end=mesial and distal surfaces
