Impact of lack of transportation on access to dental care.

Objectives: Access to healthcare may be influenced by the availability of transportation. Nevertheless, the impact of transportation challenges on access to dental care has not been thoroughly examined. This study investigates the influence of transportation availability on dental care visits, dental cleanings, and exams.

The effect of water filter pitchers on the mineral concentration of tap water.

Objectives: To investigate the effect of water filter pitchers on the concentration of different minerals in tap water.

Methods: Nine water filter pitchers (A-I) were chosen based on consumer preferences and Amazon reviews. Each filter was tested for its ability to modify the concentrations of fluoride, calcium, magnesium, potassium, and sodium in tap water.

Maternal Urinary Fluoride and Child Neurobehavior at Age 36 Months.

Importance: Recent studies in Canadian and Mexican populations suggest an association of higher prenatal fluoride exposure with poorer neurobehavioral development, but whether this association holds for US-based populations is unknown.

Objective: To examine associations of third trimester maternal urinary fluoride (MUF) with child neurobehavior at age 3 years in the US.

Design, Setting, And Participants: This prospective cohort study utilized urine samples archived from 2017 to 2020 and neurobehavioral data assessed from 2020 to 2023 from the Maternal and Developmental Risks from Environmental and Social Stressors (MADRES) pregnancy cohort, which consisted of predominately Hispanic women residing in Los Angeles, California.

Fluorotic Enamel Susceptibility to Dental Erosion and Fluoride Treatment.

The purpose of this in vitro study was to test the hypothesis that fluoride treatment can prevent dental erosion on fluorotic enamel of different severities. It followed a 3×2 factorial design, considering a) fluorosis severity: sound (TF0, Thylstrup-Fejerskov Index), mild (TF1-2), moderate (TF3-4); and b) fluoride treatment: 0 (negative control) and 1150ppmF. Human molars with the three fluorosis severities (n=16, each) were selected and randomly assigned to the two fluoride treatments (n=8).

Early Lead Exposure Associated with Molar Hypomineralization.

The purpose of this study was to determine the association between prenatal and early life exposure to lead and the presence of molar hypomineralization (MH) in a group of Mexican children. A subset of participants of the Early Life Exposure in Mexico to Environmental Toxicants (ELEMENTS) cohort study was examined for the presence of molar hypomineralization using European Academy of Pedi- atric Dentistry (EAPD) criteria. Prenatal lead exposure was assessed by K-ray fluorescence measurements of patella and tibia lead and by maternal blood lead levels by trimester and averaged over trimesters.

Urinary fluoride levels and metal co-exposures among pregnant women in Los Angeles, California.

Background: Fluoride is ubiquitous in the United States (US); however, data on biomarkers and patterns of fluoride exposure among US pregnant women are scarce. We examined specific gravity adjusted maternal urinary fluoride (MUFsg) in relation to sociodemographic variables and metal co-exposures among pregnant women in Los Angeles, California.

Methods: Participants were from the Maternal and Developmental Risks from Environmental and Social Stressors (MADRES) cohort.

Susceptibility of fluorotic enamel to dental erosion-abrasion.

Dental hard tissue conditions can be of pre- or post-eruptive nature, such as enamel fluorosis and erosive tooth wear (ETW), respectively. Dental enamel fluorosis is caused by the chronic and excessive intake of fluoride during enamel development, leading to increased fluoride concentration and increased porosity. ETW has become a common clinical condition and often impairs dental function and aesthetics.

The Saudi Arabian national demographic and health survey, 2017: Study design and oral health-related influences.

Objective: To describe the study design, and the distal and proximal influences on oral health reported in the national demographic and health survey (DHS) of the Kingdom of Saudi Arabia (KSA) in 2017.

Methods: The 2017 KSA DHS used an innovative multistage stratified random-sampling technique to select the population sample by using primary health care centers' (PHCs) catchment areas as the primary sampling unit. Over 45,000 household heads plus a family member were interviewed.

Fluoride exposure and hypothyroidism in a Canadian pregnancy cohort.

Background: While fluoride can have thyroid-disrupting effects, associations between low-level fluoride exposure and thyroid conditions remain unclear, especially during pregnancy when insufficient thyroid hormones can adversely impact offspring development.

Objectives: We evaluated associations between fluoride exposure and hypothyroidism in a Canadian pregnancy cohort.

Methods: We measured fluoride concentrations in drinking water and three dilution-corrected urine samples and estimated fluoride intake based on self-reported beverage consumption.

Maternal fluoride exposure, fertility and birth outcomes: The MIREC cohort.

Objective: Fluoride exposure >1.5 mg/L from water has been associated with adverse pregnancy and birth outcomes. Little is known, however, about the effect of fluoride at levels consistent with water fluoridation (i.

Financial assessment of the community-based dental education program at the Indiana University School of Dentistry.

Background: There is a gap in access to oral health services for millions of Americans residing in health professional shortage areas. The community-based dental education program at the Indiana University School of Dentistry is an innovative model that aims to improve access to oral health services in rural underserved Indiana.

Objective: With this study, our goal was to assess the financial implications of the program over a period of 3 years (2018-2021).

Iodine Status Modifies the Association between Fluoride Exposure in Pregnancy and Preschool Boys' Intelligence.

In animal studies, the combination of in utero fluoride exposure and low iodine has greater negative effects on offspring learning and memory than either alone, but this has not been studied in children. We evaluated whether the maternal urinary iodine concentration (MUIC) modifies the association between maternal urinary fluoride (MUF) and boys' and girls' intelligence. We used data from 366 mother-child dyads in the Maternal-Infant Research on Environmental Chemicals Study.

Fluoride Metabolism in Pregnant Women: A Narrative Review of the Literature.

Epidemiological studies use biomarkers of fluoride exposure in pregnant women as surrogate measures of fetal fluoride exposure; however, there is little understanding of how pregnancy affects fluoride metabolism and its biomarkers. This narrative review summarizes the changes of pregnancy that have the potential to impact fluoride's absorption, distribution and excretion, and highlights the limited body of evidence on the topic. The physiologic systems that experience pregnancy-associated changes relevant to fluoride's metabolism are the cardiovascular, renal, metabolic and gastrointestinal, as well bone and calcium metabolism and the body's acid-base balance.

Demarcated Primary Second Molar Hypomineralization: Prevalence Data and Associated Sociodemographic Determinants from Indiana.

Demarcated primary second molar hypomineralization (DMH-Es) is a common developmental defect of enamel, with prevalence estimates between five percent and 20 percent. From the Americas, studies exploring the problem of DMH-Es and explicitly using the European Academy of Pediatric Dentistry diagnostic criteria were limited to some South American countries, but no similar studies were available from any of the North American countries including the United States. The purpose of this study was to investigate the prevalence and sociodemographic determinants of DMH-Es among schoolchildren in Indiana, USA.

Dietary fluoride intake during pregnancy and neurodevelopment in toddlers: A prospective study in the progress cohort.

Foods and beverages provide a source of fluoride exposure in Mexico. While high fluoride concentrations are neurotoxic, recent research suggests that exposures within the optimal range may also pose a risk to the developing brain. This prospective study examined whether dietary fluoride intake during pregnancy is associated with toddlers' neurodevelopment in 103 mother-child pairs from the PROGRESS cohort in Mexico City.
