Context: The increasing death rate because of oral cancer is mainly due to its late diagnosis. Tumour markers are often detected in abnormal amounts in blood, urine or saliva of patients with certain types of cancer. Diagnosing cancer through human saliva has advantages such as low invasiveness, minimum cost and easy sample collection. We have used serum immunoglobulin A (IgA) and salivary IgA for our present study.
Aims: The aim of present study was to estimate serum and salivary IgA levels in oral leukoplakia and oral squamous cell carcinoma (OSCC) patients.
Settings And Design: The study included 40 patients; 10 in the control group, 15 cases with oral leukoplakia and 15 cases with OSCC.
Methods And Material: The blood samples and saliva were taken from clinically diagnosed oral leukoplakia and OSCC patients and were tested for IgA levels.
Statistical Analysis Used: The data were analysed using SPSS 16.0. The mean values were compared between the groups by using analysis of variance (ANOVA) followed by post-hoc test for group-wise comparison. value ≤ 0.05 was considered significant.
Results: It was observed that the comparison of levels of serum IgA in control and leukoplakia group; control and OSCC group; leukoplakia and OSCC group were found to be statistically significant. Also, comparison between the levels of salivary IgA in control and OSCC group was found to be statistically significant.
Conclusion: It is suggested that the serum and salivary IgA levels could be a better adjuvant diagnostic marker along with routine markers in patients with premalignant and malignant lesions.

Background/objectives: Salivary immunoglobulin A (IgA) is a mediator of local immunity and host defence. Altered IgA levels may predispose to bacterial invasion of the mucosa in the gastrointestinal tract, including the oral cavity. Our study aimed to present the diagnostic trends related to salivary IgA in health and disease based on a bibliometric analysis of published papers between 2009 and 2024.

Article Synopsis
- The study explores how periodontal inflammation affects both salivary gland function and the oral microbiome, highlighting the significance of these factors in overall health.
- In an experimental model with mice, researchers noticed changes in immune cell activity in the salivary glands and alterations in the oral microbiome following induced periodontitis.
- The findings emphasize a strong connection between oral bacteria, immune responses in salivary glands, and how inflammation can disrupt oral health, providing insights into maintaining oral homeostasis.
Changes in salivary biomarkers of pain, anxiety, stress, and inflammation related to tooth movement during orthodontic treatment: a systematic review.

Objective: This systematic review aimed to analyze the literature on changes in endogenous salivary biomarkers of pain, anxiety, stress, and inflammation related to tooth movement during orthodontic treatment of children and adolescents.
Material And Methods: An electronic search was performed in nine databases to identify quasi-experimental studies, without restricting publication language and year. Two reviewers extracted the data and assessed the individual risk of bias using the JBI tools, and the certainty of evidence using the GRADE tool.
Abatacept use for 24 weeks has a limited effect on salivary gland inflammation in Sjögren's disease patients.

Objectives: This study aimed to assess (1) effects of abatacept on salivary gland histology of Sjögren's disease (SjD) patients, (2) the predictive value of salivary gland histopathological characteristics at baseline for clinical response to abatacept treatment.
Methods: Patients (n=41) who participated in the Dutch ASAP-II and ASAP-III trials and international abatacept trial (IM101603) from whom a labial (n=13) or parotid (n=28) salivary gland biopsy was obtained at baseline and after 24 weeks of treatment with abatacept were included. Biopsies were analysed for SjD related histopathological features before and after abatacept (n=25) or placebo (n=16) treatment.

Mucosal infections normally cause an immune response including activation of antigen-specific B cells in regional mucosa-associated lymphoid tissue. After recirculation of plasmablasts, and maturation at mucosal surfaces or bone marrow, plasma cells produce secretory or systemic IgA. It remains uncertain to what extent secretory and systemic IgA share the same target specificities.
