摘要

背景:睡眠质量对儿童的健康有重大影响,并与口腔和全身疾病有关。它影响昼夜节律,而昼夜节律在调节内分泌和荷尔蒙系统的平衡方面起着至关重要的作用。目前的研究重点是探索它在龋齿发展中的作用,而龋齿的发展受口腔微生物群的组成和 pH 值等口腔固有因素的影响:本研究旨在调查 8 至 12 岁儿童唾液中细菌数量、pH 值和缓冲特性与睡眠模式之间的关系:这项横断面研究的对象是 85 名 8-12 岁的小学生。在获得书面同意后,采用吐唾液法收集非刺激性唾液样本。使用波斯语版的儿童睡眠习惯问卷(CSHQ)获得了参与者的睡眠模式信息。根据 CSHQ 的结果,参与者被分为两组:睡眠模式适宜组和睡眠模式不适宜组。研究比较了两组之间的变异链球菌、乳酸杆菌和白色念珠菌的细菌数量,以及唾液的缓冲能力和 pH 值。统计分析采用χ2检验、独立样本t检验和Spearman相关性检验:结果:睡眠模式不当组的 pH 值和缓冲能力明显较低(p < 0.001),乳酸杆菌和变异性酵母菌的菌落数明显较高(分别为 p < 0.001 和 p = 0.012)。白僵菌与睡眠模式之间没有关联(p = 0.121):不恰当的睡眠模式会增加致龋细菌的数量,降低唾液的 pH 值和缓冲能力。这可能是导致 8-12 岁儿童患龋齿的一个重要因素。

Association between sleep pattern, salivary cariogenic bacteria and fungi populations, pH and buffering capacity in children: A comparative study.

Background: Sleep quality has a significant impact on a child's health and is linked to oral and systemic diseases. It affects the circadian rhythm, which plays a crucial role in regulating the balance of the endocrine and hormonal systems. Current research has focused on exploring its role in the development of caries, which is influenced by inherent oral factors such as the composition of the oral microbiome and pH levels.

Objectives: This study aimed to investigate the relationship between bacterial population, pH, and buffering properties of saliva and sleep patterns in 8- to 12-year-old children.

Material and methods: This cross-sectional study was conducted on 85 elementary school children aged 8-12 years. After obtaining written consent, non-stimulating saliva samples were collected using the spitting method. The participants' sleep pattern information was obtained with the use of the Persian version of the Children's Sleep Habits Questionnaire (CSHQ). Based on the results of the CSHQ, the participants were divided into 2 groups: those with appropriate sleep patterns; and those with inappropriate sleep patterns. The study compared the bacterial population of Streptococcus mutans, Lactobacillus spp. and Candida albicans, as well as the buffering capacity and pH of the saliva between the 2 groups. The statistical analysis employed the χ2 test, the independent samples t-test and Spearman's correlation.

Results: The group with inappropriate sleep patterns had significantly lower pH and buffering capacity (p < 0.001) and significantly higher colony counts of Lactobacillus and S. mutans (p < 0.001 and p = 0.012, respectively). There was no association between C. albicans and sleep patterns (p = 0.121).

Conclusions: Inappropriate sleep patterns increase the population of caries-causing bacteria and reduce salivary pH and buffering capacity. This can be a significant factor in the development of dental caries in children aged 8-12 years.
