Five hundreds eighty children in the same arca of Ile-Ife as those examined in the last survey (in 1981) were examined in the present follow-up rescarch.The purpose of this follow-up research of 1986 were 1) to compare the carles experlence between the Nigerlan children and their Japanese counterpart and 2) to investigate the longitudinal changes of carles lesions of the same 85 subjects in Ile-Ife examined in 1981.The results obtained as follows:1.The incidence of carics in the Nigerian children was much lower than that of their Japanese counterpart.2.The caries experience of the Nigerlan children seemed to increase slightly in the urban area during five years and decrease slightiy in the rural area.3.By the follow-up research of the same subjects,it could be ascertained the initial caries disappeared by an intensive attrition on the molars,especially on the first moiars.The periodontal disease was examined in the Nigerian children, 6734 in number,using the CPITN.Tne prevalence of the periodontal discase was 84.2%,mainly containing the gingivitis, and intensive caluculus deposit,while the disturbance of the periodontal tissue was less.It will be closely related to feeding on the traditional diets.The necessity of the oral hygiene and prophylaxis should be emphasized in the children in Ile-Ife.

本次后续研究中，对伊费岛同一区域的 580 名儿童进行了检查。1986 年的后续研究的目的是 1) 比较尼日尔儿童和日本儿童之间的卡尔斯经验，2) 调查 1981 年在伊费岛检查的 85 名受试者的卡尔斯损伤的纵向变化。作为 如下：1.尼日利亚儿童的龋齿发生率远低于日本儿童。2.尼日尔儿童的龋齿经历在五年内城市地区略有增加，农村地区略有减少。3.通过对同一受试者的后续研究，可以确定初期龋齿通过磨牙特别是第一磨牙的强烈磨损而消失。 尼日利亚儿童6734人，采用CPITN，牙周病患病率为84.2%，主要以牙龈炎、牙石密集沉积为主，而牙周组织紊乱较少，与传统饮食喂养密切相关。伊费岛儿童应重视口腔卫生和预防的必要性。
