Article Synopsis
- The study aimed to create methods for assessing the shape of tooth surfaces and their potential links to cavities, using data from 147 patients' molars.
- The research analyzed detailed 3D scans of teeth and measured various surface parameters and fissure patterns, but found no significant associations between these measurements and cavity presence or severity.
- While the results were inconclusive for this specific sample, the methods developed could still be valuable for future, larger studies in clinical settings.
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.

Article Synopsis
- The study aimed to assess the prevalence and severity of molar-incisor hypomineralization (MIH) among school-aged children in Indiana, finding a 13% prevalence rate of MIH and a 52% rate for any enamel defect.
- The researchers examined 337 children using specific criteria to identify MIH and other enamel issues, discovering that factors like water fluoridation and ethnicity influenced the prevalence of general enamel defects, though not MIH itself.
- The findings emphasize the need for early identification and management of MIH, as children's condition tends to worsen with age, and dental practitioners should be aware of its common occurrence.
Article Synopsis
- The study explored how parental background influences the acceptance of various behavior guidance techniques used in treating pediatric patients.
- 142 parents participated by rating videos of different techniques, revealing notable differences in acceptance among Hispanic, Black, and White parents.
- Hispanic parents preferred voice control the most, while Black and White parents favored tell-show-do; however, acceptance varied significantly for techniques like general anesthesia and active restraint across the different racial groups.
Article Synopsis
- The Health Protection Model was applied in a community-based study to explore Latino parents' experiences and challenges related to their children's oral health in Central Indiana.
- Focus groups involving Latino caregivers revealed a lack of understanding about caries causes and a cultural belief connecting diet, particularly high carbohydrate foods, to cavities, while minimizing factors like genetics or bacteria.
- The study highlighted issues such as a gender divide in perceived responsibilities for dental care and financial and communication barriers to accessing dental services, emphasizing the need for improved oral health strategies tailored for this community.
Objectives: This study aimed to calculate the fluoride concentrations of commonly consumed foods and beverages for 2-years-old children utilizing market basket information for the US Midwest region.
Methods: Total Diet Study food lists were cross-referenced with National Health and Nutrition Examination Survey-What We Eat in America data to determine the foods and beverages to be included. Fluoride concentrations were determined using a modification of the hexamethyldisiloxane microdiffusion technique.
Objectives: Enamel fluorosis is a hypomineralization caused by chronic exposure to high levels of fluoride during tooth development. Previous research on the relationship between enamel fluoride content and fluorosis severity has been equivocal. The current study aimed at comparing visually and histologically assessed fluorosis severity with enamel fluoride content.
