DENTISTRY 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). Figure 9B.
