Insights
Saliva diagnostics offer a noninvasive method for diagnosing diseases in children. This review highlights the "omic" spectrum of salivary biomarkers for pediatric health and disease, paving the way for future advancements.
Area of Science:
- Pediatric Diagnostics
- Biomarker Discovery
- Omics Technologies
Background:
- Saliva is an ideal noninvasive diagnostic medium for infants and children.
- Unique salivary biomarker profiles aid in diagnosing various diseases and conditions.
- Omics-based discoveries (genomics, proteomics, etc.) provide powerful diagnostic information.
Purpose of the Study:
- To review current and future applications of saliva diagnostics in pediatrics.
- To highlight pediatric studies across the "omic" spectrum.
- To identify emerging frontiers in salivary diagnostics research.
Main Methods:
- Review of existing literature on salivary diagnostics in children.
- Analysis of studies utilizing "omic" approaches in pediatric saliva samples.
- Identification of key biomarkers and diagnostic applications.
Main Results:
- Saliva diagnostics are effective for detecting caries, periodontitis, and systemic conditions in children.
- Omics technologies reveal comprehensive diagnostic insights from saliva.
- Applications extend to metabolic diseases, cognitive function, stress, and immune responses.
Conclusions:
- Saliva diagnostics represent a powerful, noninvasive tool for pediatric health assessment.
- Continued research across the "omic" spectrum will expand salivary diagnostics' utility.
- Emerging frontiers promise significant advancements in early disease detection and monitoring.
Abstract:
In vulnerable populations, such as infants and children, saliva makes the perfect diagnostic medium because of its noninvasive collection, easy handling and storage of samples. Its unique biomarker profiles help tremendously in the diagnosis of many diseases and conditions. In fact, saliva genomics, proteomics, transcriptomics, metabolomics and microbiome-based discoveries have led to complementary and powerful diagnostic information. In children and neonates, saliva is the preferred medium not only for diagnosis of caries and aggressive periodontitis but also for a number of systemic conditions, metabolic diseases, cognitive functions, stress assessment and evaluation of immunological and inflammatory responses to vaccination. In this review, we provide an overview of current and future applications of saliva diagnostics to various diseases and conditions and highlight studies in paediatrics across the "omic" spectrum. Emerging frontiers in salivary diagnostics research that may significantly advance the field are also highlighted.
