The effectiveness of an oral hygiene program for children living in a children's home has been reported. However, to the best of our knowledge, no studies have evaluated the possible effects of self-checking of oral health among children residing in a children's home. The objective of this study was to examine if self-checking using plaque disclosing solution improves oral hygiene in schoolchildren living in a children's home.
We enrolled nine schoolchildren (six girls) without untreated decayed teeth living in a children's home in Japan. This preliminary study was designed as a 5-month program comprising group and individual instructions and self-checking using plaque disclosing solution. Paired t-test and Wilcoxon signed-rank test were used for statistical analysis to evaluate the change of Plaque Control Record (PCR) and Patient Hygiene Performance (PHP).
The mean PCR significantly decreased to 38.7% after 3 months of self-checking using disclosing solution compared with that before self-checking (i.e., at 1 month) (60.7%) ( < 0.01). PHP score significantly decreased to 1.4 at 4 months compared with that at baseline (2.8) and at 1 month (2.7) ( = 0.012 and = 0.018). Improvement of oral hygiene status was evaluated according to the ratio of PCR at 4 months to that at 1 month. The average improvement ratio was 0.4 ± 0.35 (range: 0.0-1.0). Significant correlation was not found between improvement rate and school grade ( = 0.63, = 0.070).
Our results suggest that self-checking with disclosing solution may be effective in improving oral hygiene among schoolchildren at a children's home.
已有报道称针对儿童福利院儿童的口腔卫生项目具有有效性。然而，据我们所知，尚无研究评估儿童福利院儿童进行口腔健康自我检查可能产生的影响。本研究的目的是检验使用菌斑显示剂进行自我检查是否能改善儿童福利院学龄儿童的口腔卫生状况。
我们招募了9名居住在日本儿童福利院且无未经治疗龋齿的学龄儿童（6名女孩）。这项初步研究设计为一个为期5个月的项目，包括小组和个人指导以及使用菌斑显示剂进行自我检查。采用配对t检验和Wilcoxon符号秩检验进行统计分析，以评估菌斑控制记录（PCR）和患者卫生表现（PHP）的变化。
与自我检查前（即1个月时）（60.7%）相比，使用显示剂进行自我检查3个月后，平均PCR显著降至38.7%（<0.01）。与基线时（2.8）和1个月时（2.7）相比，PHP评分在4个月时显著降至1.4（=0.012和=0.018）。根据4个月时与1个月时PCR的比值评估口腔卫生状况的改善情况。平均改善率为0.4±0.35（范围：0.0 - 1.0）。未发现改善率与年级之间存在显著相关性（=0.63，=0.070）。
我们的结果表明，使用显示剂进行自我检查可能对改善儿童福利院学龄儿童的口腔卫生有效。
