The impact of persistent organic pollutants on fertility: exposure to the environmental toxicant 2,3,7,8-tetrachlorodibenzo-p-dioxin alters reproductive tract immune responses.

Exposure to environmental contaminants can result in profound effects on the host immune system. One class of environmental toxicants, known as dioxins, are persistent environmental contaminants termed "forever chemicals". The archetype toxicant from this group of chemicals is 2, 3, 7, 8-tetrachlorodibenzo-p-dioxin (TCDD), an immunotoxicant that activates the aryl-hydrocarbon receptor pathway leading to a variety of changes in immune cell responses.

Guidelines for Reporting Oral Epidemiologic Studies to Inform Burden Estimation (GROESBE).

High-quality prevalence and incidence studies of oral conditions are essential for estimation of disease burden and comparison of estimates among countries and over time, as well as for priority setting, resource allocation, and planning public health action. Existing systematic reviews of the epidemiology of untreated dental caries, severe periodontitis, and edentulism, carried out for the Global Burden of Disease study, showed inadequate and incomplete reporting of the measurement of oral conditions as well as a lack of consistency and comparability with other health conditions. These issues are more accentuated in studies from low- and middle-income countries.

Association between oral health and physical performance in Brazilian older adults: SABE cohort study.

Background: Oral health is recognized as integral to general health and impaired dentition status may affect physical performance among older adults. This study evaluated the longitudinal association between clinical and self-reported oral health measures and physical performance (outcome) in Brazilian older adults.

Methods: This was a longitudinal study that used data from the second (year 2006), third (year 2010) and fourth (year 2015) waves of the Health Well-being and Aging Study conducted in Brazil.

Starch intake and caries increment: A longitudinal study in Finnish adults.

Objective: To evaluate whether changes in starch intake (in terms of amount and food sources) were associated with increments in dental caries among adults.

Design: This is an 11-year longitudinal study (2000-2011) with duplicate assessments for all variables. A 128-item FFQ was used to estimate intake of starch (g/d) and six starch-rich food groups (potatoes, potato products, roots and tubers, pasta, wholegrains and legumes).

Particulate Matter 2.5 and Severe Periodontitis Among Colombian Adults.

Aims: The primary aim was to determine the association between particulate matter 2.5 (PM) concentration at municipality-level and severe periodontitis among adults. A second aim was to evaluate contemporaneous versus lagged effects of exposure to municipality-level PM concentration on severe periodontitis.
