Article Abstract
Objectives: This study aimed to evaluate and compare the effects of methylphenidate on oral health, salivary flow rate, and quality of life in children with Attention-Deficit/Hyperactivity Disorder (ADHD), focusing on differences between short-release methylphenidate (SRM) and long-release methylphenidate (LRM) formulations.
Materials And Methods: A total of 99 children participated in this cross-sectional study (ADHD: n = 49; divided into SRM (n = 27) and LRM (n = 22) subgroups based on medication type; control: n = 50). Dental caries was assessed using the DMFT/dft indices and the International Caries Detection and Assessment System (ICDAS), while oral hygiene was evaluated using the Plaque Index (PI), Gingival Index (GI), and Bleeding on Probing (BOP). Unstimulated salivary flow rates were measured. Salivary Streptococcus mutans and Lactobacillus levels were quantified using quantitative real-time polymerase chain reaction (qPCR). Quality of life was assessed with the Child Perceptions Questionnaire (CPQ) and KIDSCREEN-10. Logistic regression analyses examined associations between oral health outcomes, ADHD status, and medication type.
Results: The ADHD group, especially SRM users, showed significantly higher DMFT scores, poorer oral hygiene, and reduced salivary flow rates compared to controls. Regression models further identified increased BOP and decreased salivary flow as predictors of ADHD and SRM use. qPCR confirmed higher Streptococcus mutans levels in SRM users. Quality of life was lower in ADHD children, particularly older SRM users.
Conclusions: Children with ADHD receiving methylphenidate exhibited poorer oral health and reduced quality of life, especially with SRM formulations.
Clinical Relevance: Clinicians should be aware that children-particularly those receiving SRM-are more likely to present with reduced salivary flow, increased plaque accumulation, and gingival inflammation. Regular dental monitoring, reinforcement of oral hygiene practices, and dietary counseling should be integrated into the care plans of these patients.

Haematopoietic cell transplantation is a widely used treatment option for (malignant) blood diseases like leukaemia. This treatment, which is preceded by chemotherapy and sometimes by total body radiation therapy, can cause serious side effects, often including the oral cavity. This thesis describes the development of hyposalivation, xerostomia and caries progression after haematopoietic cell transplantation.

Background: Regulatory T cells (Tregs) are found to be critical for maintaining immune tolerance to self-antigens; however, their status in primary Sjögren's syndrome (pSS) remains unclear. We investigated alterations in the abundance of peripheral Tregs in a large pSS cohort and their implications for patients.
Methods: Levels of CD4+CD25+FOXP3+Treg cells in the peripheral blood of 624 patients with pSS, and 93 healthy controls (HCs) were detected using modified flow cytometry (FCM).

Studies indicate that dietary patterns influence the function and redox balance of salivary glands. This study examined the effects of intermittent fasting (IF) on the function, histological structure, and redox balance of the salivary glands. Twenty 12-weeks-old male Wistar rats were randomized into two groups: ad libitum (AL), with continuous access to water and chow, and IF, subjected to 24-hour fasting on alternate days for 12 weeks.

Background: Sjögren's disease (SjD) is an autoimmune disorder characterized by sicca syndrome with undetermined roles of reactive oxygen species (ROS) and mitochondrial dynamics in the damaged glands. This study aimed to clarify the roles of ROS and mitochondrial dynamics in SjD-related hyposalivation and explored the therapeutic effect of targeting mitochondrial fission to treat hyposalivation in murine SjD.
Methods: Single-cell sequencing analysis of submandibular glands (SMGs) from mice with SjD was performed.
