The clinical development of broken mouth over a single reproductive year and the effect of two broad spectrum antibacterial agents upon it was followed in 72 Scottish Blackface ewes aged between two and three years. Using a number of dental health indices especially developed for the purpose, the amount of gingivitis, tooth movement, gum recession and pocketing were quantified and graphed for both the whole population and each group in the drug trial. All clinical features except movement fluctuated significantly with time, the fluctuations often being associated with nutritional or other environmental factors. Despite the extended use of large doses of two antimicrobial agents no significant reduction in the amount of clinical gingivitis or pocketing was evident.
对72只年龄在两岁至三岁之间的苏格兰黑脸母羊，跟踪观察了其在单个繁殖年度内烂嘴的临床发展情况以及两种广谱抗菌剂对其产生的影响。使用了专门为此目的制定的一些牙齿健康指数，对整群羊以及药物试验中的每个组的牙龈炎、牙齿移动、牙龈退缩和牙周袋形成情况进行了量化并绘制成图表。除牙齿移动外，所有临床特征均随时间有显著波动，这些波动常与营养或其他环境因素有关。尽管长期大量使用了两种抗菌剂，但临床牙龈炎或牙周袋形成的数量并无明显减少。
