Relationship between community-level variables and number of general dentists
Journal of the American Dental Association (1939)
|February 27, 2018
Summary
Community characteristics like urbanization, education, and fluoridation influence dentist distribution. Urban, young, educated communities have more dentists, while isolated, older communities have fewer.
Area of Science:
- Dental Public Health
- Community Health Assessment
- Health Services Research
Background:
- Observational data from 2014 was used to assess general dentist distribution.
- Focus on the association between community characteristics and dentist availability.
Purpose of the Study:
- To evaluate the relationship between community attributes and the number of general dentists.
- Identify factors influencing dental provider location decisions.
Main Methods:
- Utilized secondary data for 947 Iowa incorporated communities.
- Employed zero-inflated negative binomial models to analyze associations.
- Dependent variable: mean number of general dentists per 1,000 population per square mile (population density).
Main Results:
- Only 22.8% of communities reported having at least one dentist.
- Higher dentist concentrations were found in urban, young, well-educated communities with fluoridation and elementary schools.
- Fewer dentists were observed in isolated communities with older, less educated populations, lacking fluoridation and schools.
Conclusions:
- Population size is a key factor, but urbanization, demographics, fluoridation, and school presence also predict dentist numbers.
- Findings offer valuable insights for dental students and practitioners regarding practice location choices.

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

Biological organization is the classification of biological structures, ranging from atoms at the bottom of the hierarchy to the Earth's biosphere. Each level of the hierarchy represents an increase in complexity that builds upon the previous level.

01:28Ending Relationships
205
The dissolution of intimate relationships presents complex emotional and psychological challenges, particularly when emotional bonds are strong, the relationship is long-standing, and perceived alternatives are limited. This distress often intensifies in romantic breakups, where the initiator may experience greater turmoil than the rejected partner. Contributing factors include residual attachment, guilt over causing pain, and uncertainty about how to manage the situation. The stress is further...

01:11Variability: Analysis
528
Measures of variability are statistical metrics that reveal the dispersion pattern within a dataset. They are pivotal in biostatistics, providing insights into the heterogeneity within health and biological data. Variability signifies the degree to which data points diverge from one another, helping researchers understand the potential range of values and associated uncertainty within the data.
The range is a simple measure of variability, indicating the difference between the highest and...

A random variable is a single numerical value that indicates the outcome of a procedure. The concept of random variables is fundamental to the probability theory and was introduced by a Russian mathematician, Pafnuty Chebyshev, in the mid-nineteenth century.
Uppercase letters such as X or Y denote a random variable. Lowercase letters like x or y denote the value of a random variable. If X is a random variable, then X is written in words, and x is given as a number.
