Do Medicaid benefit expansions have teeth? The effect of Medicaid adult dental coverage on the use of dental services and oral health.
This article examines the effect of Medicaid adult dental coverage on use of dental care and dental health outcomes using state-level variation in dental coverage during 2000-2012. Its findings imply that dental coverage is associated with an increase in the likelihood of a recent dental visit, with the size of the effect increasing with Medicaid payment rates to dentists, and a reduction in the likelihood of untreated dental caries.

Medicaid dental coverage alone may not lower rates of dental emergency department visits.
This study examined county-level rates of ED visits for nontraumatic dental conditions in twenty-nine States in 2010 in relation to dental provider density and Medicaid coverage of nonemergency dental services. It found that county-level Medicaid-funded dental ED visit rates were lower in states where Medicaid covered nonemergency dental services than in other states, although this difference was not significant after other factors were adjusted for.

Oral health equity and unmet dental care needs in a population-based sample: findings from the Survey of the Health of Wisconsin.
The authors explored individual-, psychosocial-, and community-level predictors of oral health status in the Survey of the Health of Wisconsin Oral Health Screening project. Their results suggested that costs were a primary predictor of access to care and poor oral health status, underscoring the role that primary care, in conjunction with dental health care providers, could play in promoting oral health care, particularly in reducing barriers and promoting preventive health behaviors.

Disparities in dental care associated with disability and race and ethnicity.
The purpose of this study was to determine how the combination of disability and race and ethnicity is associated with dental examinations, delays in receiving needed care, and inability to obtain needed care among noninstitutionalized working-age adults in the United States. It found that, compared with non-Hispanic whites, other racial and ethnic groups were less likely to receive annual dental examinations.

Pediatric dental clinic location and utilization in a high-resource setting.
This study examined dental utilization by Medicaid-insured children living in a high-resource area and characterized distance and travel-related variables to accessing care. It concluded that closer proximity may contribute to the higher utilization of services observed compared with national rates.

Preventing aspiration pneumonia in high-risk nursing home residents: role of chlorhexidine-based oral care questioned again.
This commentary discusses a study by Juthani-Mehta et al in this issue of Clinical Infectious Diseases that adds more steam to the ongoing controversy of the value of chlorhexidine-based oral care by challenging an earlier study. That study found that the odds of dying from pneumonia in those who did not receive oral care was >3 times that of the group receiving oral care. By contrast, the Juthani-Mehta et al study finds no benefit to chlorhexidine use.

Dental use and expenditures for older uninsured Americans: the simulated impact of expanded coverage.
The purpose of this paper is to empirically determine if insurance alone would close the current gaps in dental use and expenditures between insured and uninsured older Americans. Comparing simulated dental use and expenditures rates of newly insured persons against the corresponding rates for those previously insured, the authors found that it would close previous gaps in use and expense.

Poor oral health literacy: why nobody understands you.
The authors examined the mistaken interpretation of the word “individuals” to be limited almost exclusively to citizens and patients. They identified gaps in knowledge, understanding, and practices regarding caries prevention among the public and all provider groups.

Examining continuity of care for Medicaid-enrolled children receiving oral health services in medical offices.
To understand continuity of oral health services for Medicaid-enrolled children utilizing the North Carolina (NC) Into the Mouths of Babes (IMB) preventive oral health program, the researchers examined the time to a dentist visit after a child’s third birthday. They found that children with only IMB visits compared to only dentist visits before age 3 had lower rates of dentist visits after their third birthday.
