This study aimed to verify the long-term effects of an oral-health-promotion program for 203 schoolchildren 24 months after the interruption of educational activities. They were clinically examined to assess dental plaque and gingival bleeding at baseline, immediately after the educational phase (EP), and 12 and 24 months after withdrawal of the EP The mean plaque scores gradually increased after interruption of the EP, and in the last assessment they were higher than the baseline scores, but similar to the ones verified 12 months after withdrawal of the EP The mean gingival bleeding scores were maintained after interruption of the EP However it was verified that in the last assessment they were lower than the previous evaluations. And, in all analyses, it was far from the baseline mean scores (P < 0.05). Analysis indicated that the duration of the program favorably influenced its outcome.
本研究旨在验证一项口腔健康促进项目在教育活动中断24个月后对203名学童的长期影响。在基线期、教育阶段（EP）结束后立即、以及EP结束后12个月和24个月对他们进行临床检查，以评估牙菌斑和牙龈出血情况。EP中断后，平均菌斑评分逐渐升高，在最后一次评估中高于基线评分，但与EP结束后12个月时的评分相似。EP中断后，平均牙龈出血评分保持稳定。然而，在最后一次评估中发现，该评分低于之前的评估结果。并且，在所有分析中，该评分与基线平均评分相差甚远（P<0.05）。分析表明，该项目的持续时间对其效果产生了有利影响。
