• PERIODONTITIS is a multifactorial infection elicited by a complex of bacterial species that interact with host tissues and cells causing the release of a broad array of inflammatory cytokines, chemokines and mediators, some of which lead to destruction of the periodontal structures, including the tooth supporting tissues, alveolar bone and periodontal ligament (Holt and Ebersole 2005). Although cattle are of worldwide economic importance in the dairy and beef industries, their dentition has not been investigated as thoroughly as that of other species.

  Cattle are diphyodont and hypsodont, and their permanent dentition has 32 teeth. The permanent incisors erupt sequentially between 1.5 and 4 years of age. All permanent premolars and the second and third molars erupt between one and three years of age (Page and Schroeder 1982)
