[Effects of different methods of tooth resection in suckling piglets].

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.
