INTRODUCTION: Healthy People 2020 includes a goal of increasing use of preventive dental care among children from low-income families. The services used to define preventive care are evidence-based services (i.e., dental sealants and professionally applied topical fluoride) and professional dental cleaning, which lacks evidence of effectiveness in preventing caries. This study examined how increasing preventive dental care use and reducing disparities by race/ethnicity among children from low-income families varied by the services included in case definitions of preventive dental care use. METHODS: Three case definitions of past-year preventive dental care use were considered: (1) the Healthy People 2020 definition; (2) receipt of an evidence-based caries prevention service; and (3) dental cleaning only. Using pooled data from the 2001-2002 and 2013-2014 Medical Expenditure Panel Survey for each definition, this study conducted in 2017 used multivariate logistic regression to estimate changes in preventive dental care use among children from low-income families by race/ethnicity. RESULTS: Use increased for all racial/ethnic groups for all definitions. Use of preventive dental care (Healthy People 2020 definition), however, was at least two times higher than evidence-based preventive dental use for all racial/ethnic groups in both survey periods. After controlling for insurance status and parental education, the disparity between non-Hispanic black and non-Hispanic white children in use of preventive dental care that was present in 2001-2002 was not detected in 2013-2014 whereas the disparity for evidence-based preventive dental care use persisted. CONCLUSIONS: Case definitions of preventive dental care that include non-evidence-based services may overstate receipt of effective preventive dental care and reductions in certain racial/ethnic disparities.

To inform selection of a control range around the Public Health Service's recommended 0.7 mg/L drinking water fluoride concentration to prevent tooth decay, the Centers for Disease Control and Prevention's Water Fluoridation Reporting System data for 2006-2010 and 2015 were analyzed. Monthly average concentration data from 4,251 fluoride-adjusted community water systems for 191,266 of 255,060 system-months (2006-2010) were compared with control ranges 0.6 mg/L to 0.2 mg/L wide. Percentages of system-months within control ranges ≥0.4 mg/L wide (e.g., +/-0.2 mg/L) were >83% versus 68% for 0.2 mg/L wide (+/-0.1 mg/L). In 2015, 70% of adjusted systems maintained averages within +/-0.1 mg/L of their system's annual average for nine of 12 months, 67% used the 0.7 mg/L target and 45% used it with a +/-0.1 mg/L control range. Adoption of the 0.7 mg/L target was underway but not completed in 2015. Control ranges narrower than +/-0.2 mg/L may be feasible for monthly average fluoride concentration.

BACKGROUND: During the past decade, investigators have reported transmissions of blood-borne pathogens (BBPs) in dental settings. In this article, the authors describe these transmissions and examine the lapses in infection prevention on the basis of available information. METHODS: The authors reviewed the literature from 2003 through 2015 to identify reports of the transmission of BBPs in dental settings and related lapses in infection prevention efforts, as well as to identify reports of known or suspected health care-associated BBP infections submitted by state health departments to the Centers for Disease Control and Prevention. RESULTS: The authors identified 3 published reports whose investigators described the transmission of hepatitis B virus and hepatitis C virus. In 2 of these reports, the investigators described single-transmission events (from 1 patient to another) in outpatient oral surgery practices. The authors of the third report described the possible transmission of hepatitis B virus to 3 patients and 2 dental health care personnel in a large temporary dental clinic. The authors identified lapses in infection prevention practices that occurred during 2 of the investigations; however, the investigators were not always able to link a specific lapse to a transmission event. Examples of lapses included the failure to heat-sterilize handpieces between patients, a lack of training for volunteers on BBPs, and the use of a combination of unsafe injection practices. CONCLUSIONS: The authors found that reports describing the transmission of BBPs in dental settings since 2003 were rare. Failure to adhere to Centers for Disease Control and Prevention recommendations for infection control in dental settings likely led to disease transmission in these cases. PRACTICAL IMPLICATIONS: The existence of these reports emphasizes the need to improve dental health care personnel's understanding of the basic principles and implementation of standard precautions through the use of checklists, policies, and practices.

OBJECTIVES: We evaluated a strategy for preventing tuberculosis (TB) in communities most affected by it. METHODS: In 1996, we mapped reported TB cases (1985-1995) and positive tuberculin skin test (TST) reactors (1993-1995) in Smith County, Texas. We delineated the 2 largest, densest clusters, identifying 2 highest-incidence neighborhoods (180 square blocks, 3153 residents). After extensive community preparation, trained health care workers went door-to-door offering TST to all residents unless contraindicated. TST-positive individuals were escorted to a mobile clinic for radiography, clinical evaluation, and isoniazid preventive treatment (IPT) as indicated. To assess long-term impact, we mapped all TB cases in Smith County during the equivalent time period after the project. RESULTS: Of 2258 eligible individuals, 1291 (57.1%) were tested, 229 (17.7%) were TST positive, and 147 were treated. From 1996 to 2006, there were no TB cases in either project neighborhood, in contrast with the preintervention decade and the continued occurrence of TB in the rest of Smith County. CONCLUSIONS: Targeting high-incidence neighborhoods for active, community-based screening and IPT may hasten TB elimination in the United States.

BACKGROUND: Although rates of tuberculosis (TB) in the United States have decreased in recent years, disparities in TB incidence still exist between U.S.-born and foreign-born people (people living in the United States but born outside it) and between white people and nonwhite people. In addition, the number of TB outbreaks among health care personnel and patients has decreased since the implementation of the 1994 Centers for Disease Control and Prevention (CDC) guidelines to prevent transmission of Mycobacterium tuberculosis. In this article, the authors provide updates on the epidemiology of TB, advances in TB diagnostic methods and TB infection control guidelines for dental settings. RESULTS: In 2008, 83 percent of all reported TB cases in the United States occurred in nonwhite people and 17 percent occurred in white people. Foreign-born people had a TB rate about 10 times higher than that of U.S.-born people. New blood assays for M. tuberculosis have been developed to diagnose TB infection and disease. Changes from the 1994 CDC guidelines incorporated into CDC's "Guidelines for Preventing the Transmission of Mycobacterium tuberculosis in Health-Care Settings, 2005" include revised risk classifications, new TB diagnostic methods, decreased frequencies of tuberculin skin testing in various settings and changes in terminology. CLINICAL IMPLICATIONS: Although the principles of TB infection control have remained the same, the changing epidemiology of TB and the advent of new diagnostic methods for TB led to the development of the 2005 update to the 1994 guidelines. Dental health care personnel should be aware of the modifications that are pertinent to dental settings and incorporate them into their overall infection control programs.
