The purpose of this study was to analyze mastication and swallowing in the elderly and confirm the association with dysphagia characteristics. A questionnaire was developed to evaluate the masticating and swallowing functions of the elderly. Mastication was analyzed using electromyography, and tongue/lip pressures were measured using Iowa Oral Performance Instrument. The results of the questionnaire showed that statistical difference in the number of teeth between the group without and with, decreased ability to swallow, and there was a correlation with lip pressure. Additionally, the higher number of teeth, the higher muscle activity, and there is a positive correlation between the number of chews and the lip pressure. Consequently, our findings suggested oral health parameters are closely associated with mastication/swallowing ability. Finally, based on the results obtained for different foods tested, we suggested that texture-modified foods are necessary to enhance swallowing ability.

Objectives: We propose a YOLOv11-TDSP model for improving the accuracy of dental abnormality detection on panoramic oral X-ray images.
Methods: The SHSA single-head attention mechanism was integrated with C2PSA in the backbone layer to construct a new C2PSA_SHSA attention mechanism. The computational redundancy was reduced by applying single-head attention to some input channels to enhance the efficiency and detection accuracy of the model.

Objectives: To examine bidirectional associations between dental caries and body mass index (BMI) among adolescents living in vulnerable communities in Brazil.
Methods: In a cohort study involving adolescents (n=323), BMI, number of decayed teeth and odontogenic infections (PUFA/pufa index) were recorded at three time points between 12 and 15 years of age. Trajectories of dental caries, odontogenic infections, and BMI were developed using group-based trajectory modelling.

Hereditary peripheral neuropathies may present as isolated neuropathy or as a part of a more complex neurological disorder. Hereditary motor sensory neuropathy is the most common form of hereditary neuropathy. The discovery of an increasing number of causative genes over the years has significantly complicated the classification of hereditary motor sensory neuropathy.

The rapid repair of intraoral mucosal injuries is crucial for restoring oral epithelial homeostasis. Alpha-ketoglutarate (αKG), a multi-potential metabolite involved in protein synthesis, epigenetic regulation, and immune response, holds the potential in tissue homeostasis and wound repair. Here, we report that administration of αKG accelerates palatal wound healing, with enhanced re-epithelialization and increased collagen deposition.

Introduction: Subjective cognitive decline (SCD) may be associated with poor oral health because of difficulty with self-care or comorbid conditions. Our study aimed to examine oral health status, use of dental services, and the prevalence of SCD among US middle-aged (45-64 y) and older (≥65 y) adults.
Methods: We conducted a cross-sectional analysis of 2022 Behavioral Risk Factor Surveillance System (BRFSS) data.
