In the present study the periodontal condition of a group of adopted 6-17 year-old children of Asian origin living in Sweden was compared with that of age- and sex matched Sweden children. Thirty-one Asian children and 31 Swedish children participated. Data on general health for all the children and on age at arrival for the Asian children was collected by interview. A clinical examination included recording of presence of plaque, supragingival calculus, bleeding on probing, probing depth, and caries. Radiographs were used to determine marginal bone loss (distance between the cemento-enamel junction and the marginal bone level > 2 mm), proximal calculus, and proximal caries. In addition, previously taken and filed radiographs of the primary dentition of the older children and current radiographs of the younger children with primary teeth were analysed to determine the prevalence of bone loss and calculus. The children of Asian origin showed a significantly higher number of surfaces with plaque and bleeding on probing. No significant differences were noted in the number of individuals with probing depths > or = 4 mm, supragingival calculus, or radiographic calculus. Three of the Asian and none of the Swedish children displayed radiographic bone loss. The retrospective analysis of all available radiographs from the primary dentition showed that 9 of 29 (31%) Asian children and 2 of 29 (7%) Swedish children had experienced bone loss in primary teeth.
在本研究中，将一组居住在瑞典的6至17岁亚洲裔领养儿童的牙周状况与年龄和性别相匹配的瑞典儿童进行了比较。31名亚洲儿童和31名瑞典儿童参与了研究。通过访谈收集了所有儿童的一般健康数据以及亚洲儿童的抵达年龄。临床检查包括记录菌斑、龈上牙石、探诊出血、探诊深度和龋齿情况。使用X线片来确定边缘骨丧失（牙骨质-釉质界与边缘骨水平之间的距离>2mm）、邻面牙石和邻面龋齿。此外，还分析了年龄较大儿童乳牙的既往存档X线片以及年龄较小儿童乳牙的当前X线片，以确定骨丧失和牙石的患病率。亚洲裔儿童的菌斑表面数量和探诊出血情况显著更高。在探诊深度≥4mm的个体数量、龈上牙石或X线片显示的牙石方面，未发现显著差异。3名亚洲儿童显示有X线片上的骨丧失，而瑞典儿童中无人显示。对乳牙所有可用X线片的回顾性分析表明，29名亚洲儿童中有9名（31%）和29名瑞典儿童中有2名（7%）乳牙出现过骨丧失。
