It is increasingly required that non-human animals in laboratories are provided with adequate enrichment to promote the welfare of the animals. In a previous publication we showed that laboratory dogs intensively used the horn of calf hooves as chewing objects. In this report, we describe the effect of calf horn on selected behaviors of 62 laboratory dogs (60 beagles, two Foxhound crossbreds) in three research facilities (A, B, C). In addition, we assessed the dogs' tooth condition and fecal consistency. The selected behaviors: "aggressive behavior," "mounting," "tussle," "coprophagy," "manipulation" of the equipment and "abnormal behavior" did not change. In facilities A and C, the dogs receiving horn showed a significant reduction in staying near the fence of the kennel and observing the outside area. By analyzing the overall behavior in facility B, we found that "exploration" increased with horn, whereas "inactivity," "social play" and "other social behavior" decreased. In conclusion, the results indicate that horn of calf hooves offers alternative stimulation. We found positive effects on tartar/plaque reduction and fecal consistency which should be confirmed in further studies.

Clinical Trial Randomized Controlled Trial
The objective of the study was to investigate the long-term effects of feeding a dental hygiene chew that has been shown to be effective in promoting periodontal health in dogs in short-term studies. Oral malodor, calculus, and plaque scores were still significantly lower after 21 months in the group that was receiving the dental hygiene chew, although gingivitis scores no longer differed significantly. There were no reports of any adverse reactions during the study. The results of the study support that feeding of the dental hygiene chew six days per week reduces accumulation of dental deposits, helps maintain periodontal health, and increases the time interval between professional periodontal intervention.

Review
This review describes some of the biochemical and physiological factors that should be considered in designing in vitro models of the oral cavity. The significance of the non-Newtonian properties and internal structures of saliva are reported as well as the ability of saliva to form biological films on all types of solid surfaces. The presence of compositional biochemical variations between absorbed salivary films is discussed for solid surfaces having different surface chemistries. The significance of the presence of small amounts of organic material in enamel and dentin is also stressed. Finally, by selecting other, more easily available secretional products than saliva, more relevant model systems for materials testing in vitro may be established than if only simple aqueous salt solutions are used.

This in vivo study describes the ultrastructural pattern of early plaque formation on various dental materials. Test pieces of amalgam, casting alloys, titanium, ceramics, glass polyalkenoate cement, composite resins, unfilled resins, and bovine enamel were attached to the buccal and lingual surfaces of the upper first molars in 3 subjects using removable intraoral splints. Specimens were exposed to the oral environment over a period of 24 h and subsequently processed for transmission electron microscopic evaluation. Only less pronounced variations could be detected in the ultrastructural appearance of the early plaque formed on the different material surfaces. However, electron microscopic observations revealed distinct differences in early biofilm formation between buccally and lingually mounted test pieces. While the bacterial colonization of specimens worn in the lingual position remained limited to the adherence of individual micro-organisms in the area of surface irregularities, a multi-layer adherence of micro-organisms was observed on all specimens carried in buccal areas. It is concluded that early plaque formation on solid surfaces is influenced predominantly by the oral environment rather than by material-dependent parameters. These findings may be ascribed to the presence of the pellicle layer, which apparently masks any difference among materials, with regard to surface properties and biocompatibility.
