A 15-year-old male forest elephant housed in a zoo sustained a fracture of the right tusk that was 10 cm inside the cheek pouch, thus exposing the tusk canal. Treatment of the cavity by packing, topical application of antibiotics, and administration of various antiseptic preparations failed; however, the tusk grew. To treat the infected, growing tusks's root canal or pulp, surgery--comparable to a pulpectomy in man--was performed with successful results.
一只圈养在动物园的15岁雄性非洲森林象右侧象牙在脸颊袋内10厘米处发生骨折，导致牙根管暴露。通过填充、局部应用抗生素以及使用各种防腐制剂来治疗牙洞均告失败；然而，象牙仍在生长。为了治疗受感染且不断生长的象牙根管或牙髓，实施了与人类牙髓摘除术类似的手术，结果很成功。
