The caries status of the permanent first molar was studied in 683 school children (aged 13-16 years) selected from six schools in Kandy. Radike (1972) criteria were used for the examination. Of 2732 first molars examined, 37 per cent were found to be carious, filled or missing. Susceptibility to caries was higher in mandibular molars (47 per cent) than in maxillary molars (25 per cent). In 36 per cent of the children all four molars were sound, while in 11 per cent they were all affected by caries. Of 998 DMF units, 676 (68 per cent) were decayed, 189 (19 per cent) filled and 133 (13 per cent) extracted. Seventy-nine per cent of the DF sites were occlusal. Results suggest that a high proportion of carious permanent molars have been neglected without the seeking of professional care. Approaches for preventive and restorative care for the permanent first molar tooth, appropriate in Third World countries, are suggested.
对从康提六所学校挑选出的683名学童（年龄在13至16岁之间）的恒牙第一磨牙龋病状况进行了研究。检查采用了拉迪克（1972年）的标准。在检查的2732颗第一磨牙中，发现37% 有龋坏、已充填或缺失。下颌磨牙的患龋易感性（47%）高于上颌磨牙（25%）。36% 的儿童四颗磨牙均完好，而11% 的儿童四颗磨牙均患龋。在998个龋失补牙面中，676个（68%）为龋坏，189个（19%）为已充填，133个（13%）为已拔除。79% 的龋补牙面位于咬合面。结果表明，很大一部分龋坏的恒牙磨牙未得到专业护理而被忽视。文中提出了适用于第三世界国家的恒牙第一磨牙预防性和修复性护理方法。
