“…The most significant cariogenic bacteria include Streptococcus mutans , Streptococcus sobrinus , Lactobacillus acidophilus , and Actinomyces species [ 25 ]. These bacteria species produce acids that dissolve the minerals in the tooth’s enamel, leading to demineralization and, ultimately, cavities [ 26 ]. After consuming sugary or starchy foods, bacteria ferment the carbohydrates, thereby producing lactic acid, which lowers the pH in the oral cavity and contributes to tooth decay [ 27 ].…”

“…For example, inadequate sleep is associated with early childhood dental caries [ 63 ], and children’s dental problems affect their sleep [ 64 ]. On the other hand, healthy sleeping habits are associated with strengthening the immune system and reducing the risk of heart and metabolic disorders [ 26 ].…”

“…Studies have shown that poor sleep or poor sleep quality can increase the risk of developing dental caries [ 27 , 48 ]. Moreover, some studies have suggested that poor sleep quality and insufficient sleep may be associated with a higher risk of dental caries, as reflected by the DMFT index [ 26 , 63 , 64 ]. One reason for this connection is that insufficient sleep can lead to changes in the body’s immune system, making it less effective at fighting off bacteria that cause dental caries [ 65 ].…”

“…Insufficient sleep has been associated with an increased risk of dental caries in adolescents [ 64 ]. Several studies have investigated the relationship between sleep duration or sleep quality and dental caries in adolescents, with some suggesting that insufficient sleep may be a risk factor for caries [ 26 , 63 , 64 , 65 ]. Thus, Sardana et al reported that irregular or late bedtimes and fewer hours of sleep were independent risk factors for caries in early childhood [ 26 ].…”

This article provides an overview of how sleep and circadian rhythm disturbances mutually influence the occurrence of dental caries and how it is possible to reduce the risk of circadian rhythm disturbances, sleep, and associated adverse effects. Dental caries is a global problem worldwide that contributes to sociological limitations. Numerous factors influence the occurrence of dental caries, from socioeconomic factors to cariogenic bacteria, dietary habits, and oral hygiene. However, sleep disorders and circadian rhythm disturbances represent a new approach in the fight against the increasing prevalence of dental caries worldwide. Bacteria in the oral cavity and the oral microbiome are mainly responsible for the development of caries, and saliva plays an important role in their regulation. The circadian rhythm regulates numerous physiological functions, including sleep and saliva production. Disturbances in sleep and circadian rhythms affect saliva production, which impacts the development of dental caries, as saliva is necessary for regulating and maintaining oral health, especially for controlling oral infections. A person’s preference for a particular time of day depends on the circadian rhythm called chronotype. Individuals with an evening chronotype have a less healthy lifestyle that can lead to a higher caries risk than individuals with a morning chronotype. Because circadian rhythms are critical to maintaining sleep homeostasis and oral health, sleep disturbances can disrupt circadian rhythms and lead to a vicious cycle.

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 χ 2 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.

Untreated Early Childhood Caries and Possible Links with Brain Development

Untreated early childhood caries (ECC) is a global public health concern. In the short term, untreated ECC can lead to pain, infection, and disrupted sleep, among other issues. In the long term, it is associated with poor oral health in later life, increased risk of caries in permanent teeth, and adverse effects on physical and psychological development. There may be a link between untreated ECC and adverse cognitive and neurodevelopmental outcomes in young children, although the exact pathways are not fully understood. One possible pathway is through the relationship between mastication and brain stimulation. Impaired masticatory function due to ECC can affect the hippocampus, a key region responsible for memory and learning. Furthermore, untreated ECC can cause chronic inflammation, leading to the release of pro-inflammatory cytokines that may damage the brain. Sleep disturbances resulting from ECC-related pain and discomfort can also impact brain development and cognitive functioning. Additionally, frequent use of antibiotics and analgesics to address ECC-related infections can disrupt the gut microbiome, potentially affecting the brain through the gut–brain axis. Untreated ECC can cause nutritional deficiencies and elevated nutritional risk, and can further hinder brain development. Addressing ECC comprehensively with early childhood health initiatives can help mitigate potential long-term consequences and promote optimal brain development in young children.
