Nomadic groups inhabiting the Kaisut desert region of Kenya were treated and studied during two successive trips. It was found that dental decay was relatively rare and advanced periodontal disease was present mostly in older patients. The mechanical action and contents of the locally available miswak stick (toothbrush tree) seem to play a significant role in control of dental diseases.
在连续两次前往肯尼亚凯苏特沙漠地区的行程中，对当地的游牧群体进行了治疗和研究。结果发现，龋齿相对较少见，而晚期牙周病主要出现在老年患者中。当地可得的牙刷树（又称“米斯瓦克棒”）的机械作用和成分似乎在控制牙科疾病方面发挥了重要作用。
