Streptococcus mutans ATCC-27607 produces exopolysaccharides that adhere to glass. In the normal geomagnetic field about 50% more polysaccharide adhere preferentially to glass surfaces facing North as compared to South facing surfaces. Reversal of the direction of the magnetic field by 180 degrees produces a similar reversal in the direction of the preferential accumulation. Reduction of the field by 90% abolishes the preferential accumulation.

Imbalance of oral microbiome homeostasis: the relationship between microbiota and the occurrence of dental caries.
BMC Microbiol

State Key Laboratory of Oral Diseases, West China School of Stomatology, National Clinical Research Center for Oral Diseases, Sichuan University, Chengdu, China.
Background: Streptococcus mutans is recognized as a key pathogen responsible for the development of dental caries. With the advancement of research on dental caries, the understanding of its pathogenic mechanism has gradually shifted from the theory of a single pathogenic bacterium to the theory of oral microecological imbalance. Acidogenic and aciduric microbial species are also recognized to participate in the initiation and progression of dental caries.

Unlabelled: Dental caries remains a prevalent chronic disease driven by dysbiosis in the oral biofilm, with playing a central role in its pathogenesis.
Objective: This study aimed to assess the effect of D-tagatose on cariogenic risk by analyzing randomized clinical trials (RCTs).
Methods: A systematic literature review was conducted targeting RCTs published up to 2024 in eight databases and two gray literature sources.

Agricultural food waste and by-products could provide high-value compounds that positively affect human and environmental health, thus representing promising ingredients for cosmeceutical products. This study explores the biological activities of tomato skin (HP) and pomegranate peel (PPE) extracts on oral mucosa to evaluate their possible use in mouthwashes. The biological activities of the extracts and the mouthwash (MW) containing them were evaluated in Human Primary Gingival Epithelial cells (HGECs).

Background: Resin composites and dental adhesives are widely used to restore carious teeth. A relatively new category of the dental adhesives, the universal adhesives (UAs) is considered user friendly because of its simplicity to use and compatibility with any adhesive strategy. However, the adhesive interface created by these adhesives is highly susceptible to cracking after polymerization which in turn facilitates the initiation of secondary caries.

Objectives: This study aimed to evaluate and compare the antibacterial properties and optical characteristics of clear orthodontic aligners coated with zinc oxide (ZnO) and magnesium oxide (MgO) nanoparticles.
Materials And Methods: In this experimental laboratory study, polyethylene terephthalate glycol (PETG) aligner samples were coated with nanoparticles of ZnO, MgO and a combination of both (ZnO + MgO). The surface coatings were analysed before and after stability testing using field emission scanning electron microscopy (FESEM).
