A Sumatran tiger had developed severely abraded canine teeth by biting on cage-bars. This resulted in weakening and marked sensitivity of the teeth. Indications for, techniques of and complications of restorative dental treatments are described. The outcome of different restorative dental treatments indicates that endodontic treatment should be carried out first if the fracture of a weakened tooth is anticipated. To improve retention, the acid-etch technique is preferred in combination with macroretentive preparations. In this case, amalgam was used successfully in combination with composite resin to restore function to a canine tooth with a large distal defect.
一只苏门答腊虎因啃咬笼栏致使犬齿严重磨损。这导致牙齿变脆弱并伴有明显敏感症状。文中描述了牙齿修复治疗的适应证、技术及并发症。不同牙齿修复治疗的结果表明，如果预计脆弱牙齿会发生折断，应首先进行牙髓治疗。为提高固位力，酸蚀技术与大固位形预备联合使用更为可取。在此病例中，汞合金与复合树脂联合使用，成功恢复了一颗有较大远中缺损的犬齿的功能。
