The Occlusal Index of Summers (1966) was used to determine the prevalence of occlusal disorders, various features of malocclusion and to estimate the orthodontic treatment needs of 12-year-old Swazi school children in the Kingdom of Swaziland. The results indicate that the current occlusal status of Swazi school children should be maintained and if possible, improved and that the delivery of highly specialised orthodontic treatment procedures is not required.
采用萨默斯（1966年）的咬合指数来确定咬合紊乱的患病率、错牙合的各种特征，并估计斯威士兰王国12岁斯威士兰学童的正畸治疗需求。结果表明，斯威士兰学童目前的咬合状况应予以维持，如有可能还应加以改善，且不需要提供高度专业化的正畸治疗程序。
