The aim of the present investigation was to evaluate the relationship between the receipt of orthodontic treatment and subsequent periodontal health. Data from 417 children who were classified at baseline as having significant occlusal variations and who were present at the follow-up examination 3 years later were selected from an original cohort of 1015. One hundred fourteen of these children received orthodontic treatment over this time period and provided two groups of children for comparison in this study. Plaque indices, bleeding indices, and degree of dental irregularity were recorded for each incisor and canine tooth. There were significant reductions in the plaque and gingivitis scores on all tooth surfaces between the baseline and 3-year examination in the two groups of children. The children who had received orthodontic treatment had the greater reduction, but this appeared to be more related to behavioral factors than to improved tooth alignment.
本研究的目的是评估接受正畸治疗与后续牙周健康之间的关系。从1015名儿童的原始队列中选取了417名儿童的数据，这些儿童在基线时被分类为有明显的咬合变化，并且在3年后的随访检查中仍在。在这段时间里，其中114名儿童接受了正畸治疗，为本研究提供了两组儿童进行比较。记录了每颗门牙和犬齿的菌斑指数、出血指数和牙齿不齐程度。两组儿童在基线检查和3年检查之间，所有牙齿表面的菌斑和牙龈炎评分均有显著降低。接受正畸治疗的儿童降低幅度更大，但这似乎更多地与行为因素有关，而不是与牙齿排列改善有关。
