conventional root canal therapy should be performed with a more predictable outcome (Figs
7A-7C).
• Root canal therapy is the treatment of choice
for end-stage pulp disease secondary to fracture, chronic pulpitis or caries. Ideal therapy
depends on the animal’s age, the age of pulp
exposure, the tooth’s condition and periapical
health (Figures 8A and 8B).
5. Crown reduction with gingival closure. This intervention can be used to treat Type 2 tooth resorption with evidence of root replacement (Figs
9A-9D). Crown reduction and restoration are indi-
cated for cases of maloccluded teeth interfering
with the opposing gingiva.
6. Orthodontic intervention. Orthodontic buttons
and elastics can be used to reposition teeth into
functional occlusion and for maxillary or mandibular fracture stabilization. Inclined planes made
from acrylic or metal can move mesioverted
mandibular canines into functional positions
(Figs 10A-10C).
