Risk of Postpartum Dental Caries: Survival Analysis of Black/African American and White Women in Appalachia.

Background: Pregnancy is associated with increased risk of caries, but the extent this increase extends into the postpartum period is poorly understood.

Study Objective: Describe the epidemiology of dental decay in the postpartum period among Black/African American and White American women and explore associations with potentially modifiable risk factors.

Materials And Methods: We analyzed data from 1,131 Black/African American and White women participating in Center for Oral Health Research in Appalachia cohorts.

Smoking and salivary microbiota: a cross-sectional analysis of an Italian alpine population.

The oral microbiota plays an important role in the exogenous nitrate reduction pathway and is associated with heart and periodontal disease and cigarette smoking. We describe smoking-related changes in oral microbiota composition and resulting potential metabolic pathway changes that may explain smoking-related changes in disease risk. We analyzed health information and salivary microbiota composition among 1601 Cooperative Health Research in South Tyrol participants collected 2017-2018.

Bacterial community modifies host genetics effect on early childhood caries.

Background: By age five approximately one-fifth of children have early childhood caries (ECC). Both the oral microbiome and host genetics are thought to influence susceptibility. Whether the oral microbiome modifies genetic susceptibility to ECC has not been tested.

Food insecurity and consumption of cariogenic foods in mothers and their two-year-old children in Appalachia.

Objectives: To describe the association between household food insecurity and intake of cariogenic foods that increase risk of dental caries.

Methods: Cross-sectional analysis of 842 mothers in Appalachia and their children participating in the Center for Oral Health Research Cohort 2 between 2011 and 2017 when their children were ~ 24 months of age. Mothers completed a telephone interview regarding cariogenic food consumption and food insecurity.

Evaluating the ecological hypothesis: early life salivary microbiome assembly predicts dental caries in a longitudinal case-control study.

Background: Early childhood caries (ECC)-dental caries (cavities) occurring in primary teeth up to age 6 years-is a prevalent childhood oral disease with a microbial etiology. Streptococcus mutans was previously considered a primary cause, but recent research promotes the ecologic hypothesis, in which a dysbiosis in the oral microbial community leads to caries. In this incident, density sampled case-control study of 189 children followed from 2 months to 5 years, we use the salivary bacteriome to (1) prospectively test the ecological hypothesis of ECC in salivary bacteriome communities and (2) identify co-occurring salivary bacterial communities predicting future ECC.

Understanding motivations behind medical student involvement in COVID-19 pandemic relief efforts.

Background: Although students were removed from patient-facing settings at the beginning of the COVID-19 pandemic due to concerns of burdening teaching physicians and depleting personal protective equipment, some leaders suggest students can be effectively utilized when personnel resources may be scarce. There have been narrative discussions surrounding medical student involvement, but no studies exploring the attitudes of these students. The authors aim to quantify the degree to which factors influenced a medical student's decision to or to not volunteer during the pandemic and to characterize medical students' attitudes towards medical professionals' duty to serve in a pandemic.

Cariogenic and oral health taxa in the oral cavity among children and adults: A scoping review.

Objective: To review published oral microbiome studies and create a comprehensive list of bacterial species found in saliva and dental plaque among healthy children and adults associated with presence of carious lesions and caries-free state (oral health).

Design: This review followed PRISMA-ScR guidelines. We searched published studies querying PUBMED and EMBASE using the following keywords: (plaque OR saliva) AND caries AND (next generation sequencing OR checkerboard OR 16s rRNA or qPCR).

Co-occurrence of yeast, streptococci, dental decay, and gingivitis in the post-partum period: results of a longitudinal study.

: The interactions between yeast and streptococci species that lead to dental decay and gingivitis are poorly understood. Our study describes these associations among a cohort of 101 post-partum women enrolled in the Center for Oral Health Research in Appalachia, 2012-2013. : All eligible women without dental caries were included (n = 21) and the remainder were randomly sampled to represent the total number of decayed, missing, and filled teeth (DMFT) at enrollment.
