Where are the Dentists in Oakcliff, TX ?

 

The map today shows the geographic location of dentists currently practicing in the Dallas, TX area. In the process of conducting our GIS research, we noticed some areas that were heavily populated with oral health services as well as areas that are likely experiencing disparities in oral health care.

To bring awareness to the current health conditions in low-income areas in South-Dallas such as Oakcliff and other communities, the Oral Health Needs Index (OHNI) made an easy-to-access, oral health focused, Geographic Information System (GIS) based tool that allows people to find services based on their environment and resources.

Identifying dental providers who accept Medicaid/Medicare and forms of dental insurance in areas of low socioeconomic status can be difficult but it also essential in tackling disparities. With OHNI, users get a clear visualization of communities with lack of services. Lack of transportation and finding participating providers is a major barrier for low-income and rural populations. Identifying these barriers and how they contribute to health disparities experienced by under-served communities is important. It allows for a better understanding of ways to combat the health disparities in disadvantaged communities.

Radon Levels in the USA

This is a follow up post about the radon levels in the United States of America. As mentioned in an earlier post, radon is formed when uranium breaks down into radium, which breaks down into radon. Radon is absorbed by the soil and ends up in water wells and home foundations. According to the Environmental Protection Agency (EPA), radon levels shouldn’t exceed 4.0 pCi/L (pico curies per liter). The map below shows the radon levels by color – yellow representing Zone 1; counties where average indoor radon screening levels are less than 2pCi/L, orange representing Zone 2, counties where average indoor radon screening levels are between 2 and 4 pCi/L, and red representing Zone 3, counties where average indoor radon screening levels exceed 4pCi/L.  According to the National Radon Defense, the best way to know the radon level in your home is to test for it.

According to the March of Dimes website, there has been an increase in the rate of preterm births in the U.S., rising from 2% to 9.8% in 2016. Furthermore, their data show significant differences in preterm birth rates, based on race and zip code. Below is a map of this data for the U.S. The colors are based on a “grade” that the March of Dimes has given each state based on the rate of preterm birth rates in that state. Visit the March of Dimes website here to find out more information on each state’s preterm birth rate report card.
