“…They usually result from the splitting of a bud or from local hyperactivity of the dental lamina (Garvey et al, 1999), although the topic is not resolved yet (Henderson & Greene, 1975). Studies of such anomalies in wild and domestic pigs have been carried out for quite a while (Gupta, 1978;Miles & Grigson, 1990;Feldhammer & McCann, 2004;Kierdorf et al, 2004b;Konjevic et al, 2006, and so on).
