“…ECC is a preventable disease and its early diagnosis is very important [30]. Besides diagnosed risk factors of ECC, changing in salivary composition is one of the risk factors with signi cant importance in early disease diagnosis [31]. Biomarker-based diagnostic methods can play an important role in early diagnosis of this disease.…”

Background: Early childhood caries is the most common infectious disease in childhood, with a high prevalence in developing countries. Recognition of the factors affecting early childhood caries and its pathophysiology, allows better control of disease. Cystatin S as one of the salivary proteins, has an important role in pellicle formation, tooth re-mineralization and protection. The aim of the present study is to assess salivary cystatin S levels and demographic data in early childhood caries children in comparison with caries-free ones using statistical analysis and machine learning methods. Methods: A cross-sectional case-control study was undertaken on 20 cases of early childhood caries and 20 caries-free children as a control group. Unstimulated whole saliva samples by suction method was collected. Cystatin S concentrations were determined using human cystatin S ELISA kit. A checklist was collected for each participant about the demographic characteristics, oral health status and dietary habits by interviewing parents. The regression and receiver operating characteristic (ROC) curve analysis was done to evaluate the potential role of cystatin S salivary level and demographic using machine learning and statistical analysis.Results: The mean value of salivary cystatin S concentration in early childhood caries group was 191.55±81.90 (ng/ml) and in caries-free group was 370.06±128.87 (ng/ml). T-test analysis showed that there is a statistically significant difference between early childhood caries and caries-free group in salivary cystatin S level (p: 0.032). Investigation of area under the curve and accuracy of ROC curve revealed that logistic regression model based on the salivary cystatin S levels and birth weight had most and acceptable potential for discriminating of early childhood caries from caries-free controls. After that the machine learning models and finally salivary cystatin S levels had more capability for differentiation of early childhood caries from caries-free controls.Conclusion: Salivary cystatin S in caries-free children was higher than the children with early childhood caries. Therefore, cystatin S protein can be used as a biomarker for early prediction of early childhood caries, furthermore cystatin S is a protective factor against dental caries.

Background Early childhood caries is the most common infectious disease in childhood, with a high prevalence in developing countries. The assessment of the variables that influence early childhood caries as well as its pathophysiology leads to improved control of this disease. Cystatin S, as one of the salivary proteins, has an essential role in pellicle formation, tooth re-mineralization, and protection. The present study aims to assess salivary cystatin S levels and demographic data in early childhood caries in comparison with caries-free ones using statistical analysis and machine learning methods. Methods A cross-sectional, case–control study was undertaken on 20 cases of early childhood caries and 20 caries-free children as a control. Unstimulated whole saliva samples were collected by suction. Cystatin S concentrations in samples were determined using human cystatin S ELISA kit. The checklist was collected from participants about demographic characteristics, oral health status, and dietary habits by interviewing parents. Regression and receiver operating characteristic (ROC) curve analysis were done to evaluate the potential role of cystatin S salivary level and demographic using statistical analysis and machine learning. Results The mean value of salivary cystatin S concentration in the early childhood caries group was 191.55 ± 81.90 (ng/ml) and in the caries-free group was 370.06 ± 128.87 (ng/ml). T-test analysis showed a statistically significant difference between early childhood caries and caries-free groups in salivary cystatin S levels (p = 0.032). Investigation of the area under the curve (AUC) and accuracy of the ROC curve revealed that the logistic regression model based on salivary cystatin S levels and birth weight had the most and acceptable potential for discriminating of early childhood caries from caries-free controls. Furthermore, using salivary cystatin S levels enhanced the capability of machine learning methods to differentiate early childhood caries from caries-free controls. Conclusion Salivary cystatin S levels in caries-free children were higher than the children with early childhood caries. Results of the present study suggest that considering clinical examination, demographic and socioeconomic factors, along with the salivary cystatin S levels, could be usefull for early diagnosis ofearly childhood caries in high-risk children; furthermore, cystatin S is a protective factor against dental caries.

ObjectiveSome salivary proteins seem to be differently abundant among caries-free (CF) and caries-affected (CA) individuals, but previous results are contradictory precluding that definitive conclusion be drawn. A pooled analysis of the available evidence may provide more robust data on identifying oral cavity protein patterns among CF and CA individuals. This systematic review and meta-analysis (PROSPERO CRD42021269079) aimed to compare the oral cavity protein abundance among caries-free and caries-affected individuals.MethodsThis study was conducted following PRISMA guidelines. PubMed, Embase, and Web of Science databases were systematically assessed (up to February 2023) to retrieve clinical studies written in English, German, or in Latin-based languages that compared the oral cavity protein abundance among CF and CA individuals. Data extraction and methodological quality assessment (NIH guidelines) were independently performed by two investigators. Qualitative synthesis was performed from all included studies and meta-analysis was performed using a random-effects model with inverse variance for studies that reported the concentration of proteins or enzymatic activity. Standardized mean difference (SMD) with respective 95% confidence interval (CI) were calculated for each outcome.ResultsA total of 90 studies (two cohort and 88 cross-sectional designs) of more than 6,000 participants were selected for data extraction, being the quality of evidence graded as “fair” for most of them. The oral cavity of CF individuals presented lower total protein concentration [SMD = 0.37 (95% CI: 0.07–0.68; 18 studies)], lower total antioxidant capacity [SMD = 1.29 (95% CI: 0.74–1.85); 17 studies], and lower carbonic anhydrase activity [SMD = 0.83 (95% CI: 0.58–1.09); three studies], whereas CA individuals presented lower carbonic anhydrase concentration [SMD = −0.66 (95% CI: −1.00 to −0.32); three studies], urease [SMD = −0.95 (IC 95%: −1.72 to −0.17); four studies], and arginine deiminase system [SMD = −2.07 (95% CI: −3.53 to −0.62); three studies] activities. Antimicrobial peptides, secretory immunoglobulin-A concentrations and alpha-amylase activity were similar among individuals.ConclusionDifferences on oral cavity protein abundance were observed among CF and CA individuals. These data indicate some protein patterns for the oral health and dental caries conditions. Even when statistically significant, some of the results were not very consistent. Cohort studies need to be conducted to validate these results.
