Aim: The aim of the present study was undertaken to correlate the glucose levels in saliva and blood of diabetic and healthy nondiabetic individuals and to determine the efficacy of saliva as a diagnostic tool.

Setting And Design: This was a case-control study.

Materials And Methods: Forty-five patients previously diagnosed with diabetes mellitus and 45 healthy controls were included in the study. The patients and controls were asked to come to the clinic in the morning, after 8-10 h fasting. At that time, 5 ml of venous blood and unstimulated saliva was collected from both the groups, and 2 h after meal, again, venous blood and unstimulated saliva were collected. The saliva and sera from blood samples were subjected to glucose estimation. Saliva was collected in sterilized vials, and blood was collected in test tubes. Glucose estimation was done by oxidase-peroxidase method.

Statistical Analysis: Pearson's correlation coefficient, Student's -test and paired -test were used for statistical analysis.

Results: Correlation coefficient values show that there is a significant positive correlation between fasting blood and fasting salivary glucose levels and postprandial blood and postprandial salivary glucose levels.

Conclusion: Salivary glucose level estimation can be used as a potential indicator in screening, diagnosis and monitoring of diabetes mellitus. Furthermore, it is an easy and noninvasive method.

Background: Salivary compounds can be used as diagnostic markers for changes in the oral cavity that cause oral problems in type 2 diabetes mellitus (T2DM).

Methods: This meta-analysis searched PubMed/Medline, EMBASE, Scopus and Cochrane Library, and the Web of Science until Nov 2023. The observational studies included patients with T2DM and healthy controls aged > 18 yr with no oral health problems or systematic or periodontal diseases.

Article Synopsis
  • Pregnancy involves significant hormonal and metabolic changes to support fetal development, which the study investigates through changes in the salivary microbiome and biochemical markers between the second and third trimesters.
  • Saliva samples from 45 pregnant women were analyzed using advanced DNA sequencing techniques, revealing notable shifts in microbial diversity, including a 3-fold increase in Bacteroidota and changes in other microbial taxa.
  • Biochemical changes included increased BMI, pulse rate, glucose, and cholesterol levels in the third trimester, along with correlations between these factors and microbial abundance, emphasizing the need for monitoring oral health and metabolic health during pregnancy.

A step towards non-invasive diagnosis of diabetes mellitus using synthesized MOF-MXene hybrid material with extended gate field-effect transistor integration.

The increasing demand for non-invasive and non-enzymatic glucose sensors is driven by the objective of eliminating the need for blood pricks from the body and enabling enzyme-free detection of glucose for diagnosing diabetes mellitus. To address this need, we synthesized Ni MOF-MXene (Ni) hybrid material through a one-pot synthesis method, which acts as a catalyst to detect salivary glucose using an extended gate field effect transistor (EGFET) method. The resulting sensor exhibits good selectivity towards glucose over common interfering molecules such as sucrose, fructose, maltose, uric acid, and ascorbic acid under physiological conditions in saliva.

Objective: This study aimed to analyze the subgingival and salivary microbiome and metabolome in diabetic periodontitis patients with varying glycemic levels.

Methods: Forty-two diabetic periodontitis patients were sampled of saliva, gingival crevicular fluid (GCF), and blood, and categorized into three groups based on systemic glycemic status. The microbiome was assessed using full-length 16S rRNA gene sequencing.

This study aimed to analyze salivary glucose levels and pH in relation to the intensity of dental caries in healthy, nondiabetic adults. The study was conducted on 61 patients who were assigned to individual groups based on dental examinations and the calculation of the decayed, missing, and filled teeth (DMFT) index. Group 1 (control) included 15 caries-free persons (DMFT=0).
