Epizootic examinations were made on 796 newborn piglets to test the consequences of the resection of a piglet's canine and lateral incisor teeth on its first day of life. As a comparative examination the resection was carried out with side-cutter pliers or with the teeth grinder PIGMATIC 110. A third group of piglets was not treated. Histological, radiographic and bacteriological examinations were made of 10 piglets--in each case with piglets with the resection with side-cutter pliers or with the teeth grinder. 48% of ground teeth reacted with an inflammation of the pulp. The clipping of the crown of teeth with side-cutter pliers caused pulpitis in 92% of the teeth. Inflammation of the gingiva could almost only be seen around clipped teeth. Splinters only occurred with teeth which had been clipped with side-cutter pliers. Gingivitis and pulpitis extended along the splinters to the bottom of the root. Bites among the litter mates were more frequent in the group of piglets whose teeth had not been treated than in the group of piglets with resected teeth. Compared to the grinding or the clipping of needle teeth, bites to the sow's udder were much more frequent if the resection had been omitted. During the whole period of examination the mortality of piglets was at its lowest in the group of piglets with clipped teeth. The development of grinding instruments for the resection of needle teeth presents a method which reduces the negative consequences of the conventional resection with side-cutter pliers and shows clearly the advantages of resection. In terms of animal welfare, teeth resection is an amputation and therefore every case requires veterinary justification.
对796头新生仔猪进行了流行病学检查，以测试仔猪出生第一天切除犬齿和侧切牙的后果。作为对比检查，切除操作使用侧切钳或PIGMATIC 110型磨齿器进行。第三组仔猪未进行处理。对10头仔猪进行了组织学、放射学和细菌学检查——每种情况均使用侧切钳或磨齿器进行切除的仔猪。48%的磨齿出现牙髓炎症。用侧切钳修剪牙冠导致92%的牙齿出现牙髓炎。几乎仅在修剪过的牙齿周围可见牙龈炎症。碎片仅出现在用侧切钳修剪过的牙齿上。牙龈炎和牙髓炎沿着碎片延伸至牙根底部。未处理牙齿的仔猪组中，同窝仔猪之间的咬伤比切除牙齿的仔猪组更频繁。与磨齿或修剪犬齿相比，如果不进行切除，咬母猪乳房的情况要频繁得多。在整个检查期间，修剪牙齿的仔猪组仔猪死亡率最低。开发用于切除犬齿的磨齿器械提供了一种方法，可减少传统侧切钳切除的负面影响，并清楚显示切除的优势。就动物福利而言，牙齿切除是一种截肢手术，因此每种情况都需要兽医证明其合理性。
