Figure 3.11 Dental Stopping (gutta percha) is useful for canals of large diameter. Heating softens them, while a cold glass slab or alcohol hardens them.

Figure 3.13 For pulp canals size 90 or greater, for efficiency, we favor GuttaFlow 2, followed by a Master Apical Gutta Percha point.

Figure 3.14 GuttaFlow 2 can be delivered via a 20‐gauge catheter, but an 18‐gauge or even a 14‐gauge make delivery easier, providing the root canal is wide enough to accommodate them.

4 Dental Form and Function as it Relates to Dental Therapy of Wild Animals
NOTE: Step‐by‐step therapeutic examples follow this section. Below is an outline indicating effective dental treatment modalities for various tooth types.
Elodont: Teeth that are continuously growing and have open apices. If vital, elodont teeth are better treated with pulpotomy. If necrotic, then root canal therapy or extraction is indicated.
1 Animals with only anterior elodont teeth (most rodents, e.g. rats, mice, squirrels; elephant tusks; hog tusks; hippo canines and incisors; upper incisors of hyrax).
2 Animals with both anterior and posterior elodont teeth. (Examples include Lagomorphs and some rodents [guinea pigs and chinchilla]; wombats are the sole marsupials).
3 Animals with only posterior elodont teeth (e.g. edentates [anteaters, armadillo, pangolins and sloths], and the primitive ungulate [aardvark]).
Tusks are elodont teeth:
Proboscidea: African and Asian elephant tusks are maxillary lateral incisors (2I2).
Artiodactyla: Tusks of hogs, and pigs, including babirusa are the maxillary and mandibular canines.
