Mandibular canine tooth luxation injury in a dog.

A mixed breed dog was presented for lateral luxation of the mandibular left canine tooth following oral trauma. This case report describes the management of this injury including reduction, stabilization using a wire reinforced acrylic splint, and standard endodontic therapy of the mandibular left canine tooth.

Surgical extraction of a fractured, non-vital deciduous tooth in a tiger.

A 10-month-old, female/intact tiger (Panthra tigris) was presented for a fractured deciduous mandibular right canine tooth, mandibular swelling, and a cutaneous draining tract ventral to the apex of the fractured tooth. The tooth had chronic pulpal exposure and was considered non-vital with periapical osteomyelitis. This case report describes treatment to optimize normal development and eruption of the permanent mandibular right canine tooth.

Comparison of two heated gutta-percha obturation techniques of the mandibular first molar in the dog.

An in vitro study compared two heated gutta-percha obturation techniques of the mandibular first molar in the dog. Thirty hemimandibles were harvested from adult dog cadavers. The mandibular first molars were instrumented and obturated using either the ThermaFil Plus technique or the SuccessFil vertical compaction technique. Obturation times were recorded and three radiographic views were taken of all teeth for evaluation of the endodontic fill. Fifty-two of the mandibular first molar roots were evaluated in the apical dye leakage portion of the study. The ThermaFil Plus obturation technique required less time and provided a better radiographic endodontic fill, however there was significantly greater apical dye leakage in this technique compared with teeth that were obturated using the SuccessFil vertical compaction technique.
