Association between more complex special care needs and overweight status and adolescents' difficulty with dental caries.

Objective: Little is known about dental caries experience in adolescents with overweight and complex special health care needs (SHCNs).

Methods: Adolescent data (10-17 years) from the 2016-2020 National Survey of Children's Health (n = 91,196) was analyzed. The sample was grouped into the following: more complex SHCN and overweight, more complex SHCN without overweight, less complex SHCN and overweight, less complex SHCN without overweight, no SHCN but with overweight, and neither SHCN nor overweight.

Tooth-Specific Distribution and Associated Microbiome.

Dental caries is multifactorial and polymicrobial in nature and remains one of the most common oral diseases. While caries research has focused on as the main etiological pathogen, its impact at the tooth level is not fully understood. In this cross-sectional study, the levels and distribution of in the posterior teeth at different dentition stages were investigated along with the corresponding tooth-specific microbiome.

Effect of Cigarette and E-Cigarette Smoke Condensates on Biofilm Formation and Gene Expression.

Smoking triggers environmental changes in the oral cavity and increases the risk of mucosal infections caused by such as oral candidiasis. While cigarette smoke has a significant impact on , how e-cigarettes affect this oral pathogen is less clear. Here, we investigated the effect of cigarette and e-cigarette smoke condensates (CSC and ECSC) on growth, biofilm formation, and gene expression.

Oral Microbiome: /Caries Concordant-Discordant Children.

Dental caries remains the most common chronic disease in children, and the respective etiology is not fully understood. Though is an important factor in the initiation and progression of caries, its presence is not always associated with the disease. The existence of caries discordant populations, in which counts do not correlate with caries experience, poses a challenging problem.

The impact of fixed orthodontic appliances and clear aligners on the oral microbiome and the association with clinical parameters: A longitudinal comparative study.

Introduction: Orthodontic treatment interferes with oral hygiene and promotes plaque retention, which leads to gingival inflammation and enamel demineralization. Although removable clear aligners (CAs) are designed to improve oral hygiene compared with fixed appliances (FAs), comprehensive studies comparing their respective effects on the oral microbiome are limited. This longitudinal study investigated the microbial changes during orthodontic treatment with FA and CA in correlation with clinical parameters.

Oral colonization of and in children with or without fixed orthodontic appliances: A pilot study.

Background/purpose: Adolescents undergoing fixed orthodontic therapy have an increased risk of oral diseases due to additional plaque accumulation sites. However, the effect of fixed orthodontics appliances (FOAs) on the colonization of () and (), two synergistic oral pathogens, is largely unknown and was, therefore, the primary objective of this pilot investigation.

Material And Methods: Sixteen children aged 10-15 years were enrolled, nine in the FOA and seven in the control groups.

Pilot study on selective antimicrobial effect of a halitosis mouthrinse: monospecies and saliva-derived microbiome in an in vitro model system.

Background: Halitosis refers to malodor emanating from the oral cavity. Several mouthrinses with halitosis-reduction exist on the market, but their effect on the oral microbiome is largely unknown. In this study, we used an efficient model system to investigate a test mouthrinse's impact on the oral microbiome.

Omics and interspecies interaction.

Interspecies interactions are key determinants in biofilm behavior, ecology, and architecture. The cellular responses of microorganisms to each other at transcriptional, proteomic, and metabolomic levels ultimately determine the characteristics of biofilm and the corresponding implications for health and disease. Advances in omics technologies have revolutionized our understanding of microbial community composition and their activities as a whole.
