In 4A, a tooth stump after amputation of the crown (an intentional complex crown fracture) is seen, with the red dot representing bleeding pulp tissue. In 4B, powdered mineral trioxide aggregate is being introduced into the pulp chamber with a sterile paper point. In 4C, a glass ionomer is being used as a cavity liner. And in 4D, a bonded composite restoration is being cured with ultraviolet light. material (most often gutta percha.) It is a much less invasive treatment than tooth extraction, and the patient retains its teeth (Figures 5A & 5B). Bonded composite restoration Dental composite is a ﬁlled organic resin that closely mimics the color and strength of natural teeth. Dental composite can be bonded to the tooth surface (enamel or dentin) to restore defects, seal dentin tubules, and protect the underlying tooth structure. The bonding procedure involves treating the tooth with phosphoric acid to remove some of the hydroxyapatite crystals found in enamel and dentin and then placing a bonding agent that ﬂows into the pits left by the crystal removal, which results in a micromechanical lock. The composite, made of a resin matrix and inorganic ﬁller, is placed over the bonding agent, shaped, and polymerized into its solid form. Finally, the composite can be polished (Figures 6A-6D). Crown restoration Crown restoration is the placement of a manufactured crown or cap over the injured and repaired tooth. Any endodontic treatment should be performed before crown placement. A margin is cut around the tooth for the crown to sit in, and the remaining tooth is shaped following the natural taper toward the cusp. Impres- 5A & 5B. In the dental radiograph at top (5A), the left maxillary ﬁrst incisor in a dog has a complex crown fracture (1) and periapical radiolucency (2), indicating endodontic disease. The dental radiograph at bottom (5B) shows the same tooth after root canal treatment. The root canal has been cleaned, shaped, and ﬁlled with a combination of rubber (gutta percha) and cement (AH26 —Dentsply International). 368 July 2008 VETERINARY MEDICINE
