Article Abstract
Objective: To evaluate the feasibility of employing metabonomics method in identification of oral pathogenic bacteria.
Methods: The Streptococcus mutans ATCC25175 and Actinomyces viscosus ATCC15987 were respectively inoculated in same certain culture medium. The growth curves of the inoculated bacteria were drown by turbidimetry. The culture solutions in four different growth phases of the both bacteria were used to test with the 1H-Nuclear magnetic resonance (1H-NMR) spectroscopy respectively. The data of 1H-NMR spectroscopy results were analyzed by principal components analysis (PCA).
Results: The PCA showed the obvious clustering phenomena and the points of two group data stayed differentially together by two clusters. Therefore, the NMR-based metabonomics profiles can discriminate the two different kind of bacteria.
Conclusion: The metabonomics can be expected to be a kind of promising useful method in quick discrimination of oral pathogenic bacteria.

Objective: It is well-established that occlusion and dental arch form are related to the morphology and function of the oral soft tissues. Oral soft tissue dynamic assessment is important for elucidating the causes of malocclusion and developing effective treatment methods. We previously developed a small mouthguard-type sensing device for measuring oral soft tissue pressure; however, its continuous measurement performance had not been thoroughly evaluated.

Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by persistent inflammation and is often associated with poor oral health. Cytokines play a central role in RA immunopathogenesis. This case-control study investigated the involvement of salivary interleukin-17A (IL-17A) and interleukin-18 (IL-18) in RA patients in relation to oral health status.

Aim: To characterise periodontal and faecal microbiomes of individuals with periodontal health (PH) and diseases, and evaluate associations with periodontal, sociodemographic, anthropometric, nutritional and lifestyle factors.
Materials And Methods: Dental biofilm and faecal samples from individuals (n = 24/group) with PH, gingivitis (GG) and periodontitis (PE) were sequenced (16S rRNA). Anthropometric data and questionnaires on demographics, lifestyle, diet and intestinal habits were collected.

Biofilms are microbial communities that adhere to surfaces and each other, encapsulated in a protective extracellular matrix. These structures enhance resistance to antimicrobials, contributing to 65-80% of human infections. The transition from free-living cells to structured biofilms involves a myriad of molecular and structural adaptations.
