The aim of this investigation was to study the periodontal status at the ages of 15 and 20 years in the same individuals. Gingival and periodontal data from 100 adolescents in 1973 constituted the basic material. Eighty subjects could be reexamined in 1978. The mean number of teeth per subject was 27.1 both in 1973 and in 1978. Three individuals in 1973 and two in 1978 had no bleeding gingival units. There was a decrease between 1973 and 1978 in the number of subjects with a high number of inflamed gingival units. The buccal and lingual surfaces also showed lower prevalence of gingivitis, while the proximal surfaces showed a slight increase in prevalence. The prevalence of surfaces with plaque in 1978 was decreased for buccal and lingual surfaces but slightly increased for proximal surfaces. Sixty-six individuals in 1973 and 71 in 1978 had no pocketing. Altogether 75 tooth surfaces with pocketing were diagnosed in 1973 and 21 in 1978. Most of the pockets were located at the proximal surfaces of the molars. Four individuals with infrabony defects in one to two sites were found in 1973 and five in 1978. No progression of the bony defects found in 1973 seemed to have occurred during the 5-year period. In spite of the frequent proximal areas with gingivitis, very few 20-year-olds showed signs of marginal bone loss, which indicates that gingivitis does not necessarily lead to destructive periodontitis in young people.
本研究的目的是对同一批个体在15岁和20岁时的牙周状况进行研究。1973年100名青少年的牙龈和牙周数据构成了基础材料。1978年对其中80名受试者进行了复查。1973年和1978年每位受试者的平均牙数均为27.1颗。1973年有3人、1978年有2人牙龈单位无出血。1973年至1978年，牙龈炎症单位数量较多的受试者人数有所减少。颊面和舌面的牙龈炎患病率也较低，而邻面的患病率略有增加。1978年，颊面和舌面有菌斑的表面患病率下降，而邻面略有上升。1973年有66人、1978年有71人无牙周袋形成。1973年共诊断出75个有牙周袋的牙面，1978年为21个。大多数牙周袋位于磨牙的邻面。1973年发现4人有一至两个部位的骨下袋，1978年为5人。在这5年期间，1973年发现的骨下袋似乎没有进展。尽管邻面经常出现牙龈炎，但很少有20岁的人出现边缘骨丧失的迹象，这表明牙龈炎在年轻人中不一定会导致破坏性牙周炎。
