Preventing percutaneous injuries among dental health care personnel

BACKGROUND: The Occupational Safety and Health Administration and the Centers for Disease Control and Prevention (CDC) recommend that health care personnel (HCP) adopt safer work practices and consider using medical devices with safety features. This article describes the circumstances of percutaneous injuries among a sample of hospital-based dental HCP and estimates the preventability of a subset of these injuries: needlesticks. METHODS: The authors analyzed percutaneous injuries reported by dental HCP in the CDC's National Surveillance System for Health Care Workers (NaSH) from December 1995 through August 2004 to describe the circumstances. RESULTS: Of 360 percutaneous injuries, 36 percent were reported by dentists, 34 percent by oral surgeons, 22 percent by dental assistants, and 4 percent each by hygienists and students. Almost 25 percent involved anesthetic syringe needles. Of 87 needlestick injuries, 53 percent occurred after needle use and during activities in which a safety feature could have been activated (such as during passing and handling) or a safer work practice used. CONCLUSIONS: NaSH data show that needlestick injuries still occur and that a majority occur at a point in the workflow at which safety syringes--in addition to safe work practices and recapping systems--could contribute to injury prevention. CLINICAL IMPLICATIONS: All dental practices should have a comprehensive written program for preventing needlestick injuries that describes procedures for identifying, screening and, when appropriate, adopting safety devices; mechanisms for reporting and providing medical follow-up for percutaneous injuries; and a system for training staff members in safe work practices and the proper use of safety devices.     

Metabolic syndrome: pathogenesis, medical care and dental implications

BACKGROUND: The dental literature contains little information about metabolic syndrome (MetS) and its dental implications. TYPES OF STUDIES REVIEWED: The authors conducted a MEDLINE search for the period 2000 through 2005, using the term "metabolic syndrome" to define its pathophysiology, medical treatment and dental implications. RESULTS: MetS is the co-occurrence of abdominal obesity, hyper-triglyceridemia, reduced high-density lipoprotein cholesterol levels, hypertension and impaired fasting glucose, which results from consumption of a high-calorie diet and decreased levels of physical activity superimposed on the appropriate genetic setting. Components of MetS synergistically promote the development of atherosclerosis, resulting in myocardial infarction and stroke. CLINICAL IMPLICATIONS: Deteriorating oral health status is associated with worsening of the atherogenic profile. Tooth loss often results in chewing difficulties because of inadequate occlusive surfaces and may lead to alterations in food selection and dietary quality. This, in turn, adversely affects body composition and nutritional status, both of which are related to vascular health. Dentists should develop treatment plans that preserve and restore the dentition, thus ensuring maximum masticatory efficiency and affording patients the optimum opportunity to consume food that will not foster atherogenesis.     

Factors associated with access to dental care for children with special health care needs

BACKGROUND: The authors examined the relationship between receipt of routine medical care and receipt of dental care among children with special health care needs (CSHCN) who resided in the American Dental Association's Fifth Trustee District, which includes Alabama, Georgia and Mississippi. METHODS: The authors conducted a cross-sectional study using data from the 2001 National Survey of Children with Special Health Care Needs, a module of that year's State and Local Area Integrated Telephone Survey (sponsored by the U.S. Department of Health and Human Services' Maternal and Child Health Bureau of the Health Resources and Service Administration, Rockville, Md., and conducted by the Centers for Disease Control and Prevention, Atlanta). The authors used bivariate and logistic regression analyses to explore the relationships (n = 2,092) between predisposing, enabling and need factors and receipt of dental care. RESULTS: The parents of an estimated 76 percent of CSHCN in the district reported that their child had a need for dental care in the previous 12 months. Of these, 13.1 percent did not receive care. Failure to obtain needed dental care was associated with failure to obtain routine medical care, as was having a lower income. CONCLUSIONS: Failure to obtain routine medical care may be a risk factor for failure to obtain dental care. Any income below 400 percent of the federal poverty guidelines appears to be a barrier to receiving dental care for CSHCN. PRACTICE IMPLICATIONS: Providers of routine medical care may play an important role in linking CSHCN to dental care. Investigators need to examine other barriers to dental care for CSHCN. Strategies to optimize access to dental care for CSHCN at all income levels are needed.     

Assessment of treatment provided by dental health aide therapists in Alaska: a pilot study

BackgroundDental health aide therapists (DHATs) in Alaska are authorized under federal law to provide certain dental services, including irreversible dental procedures. The author conducted this pilot study to determine if treatments provided by DHATs differ significantly from those provided by dentists, to determine if DHATs in Alaska are delivering dental care within their scope of training in an acceptable manner and to assess the quality of care and incidence of reportable events during or after dental treatment.MethodsThe author audited the dental records of patients treated by dentists and DHATs who perform similar procedures for selected variables. He reviewed the records of 640 dental procedures performed in 406 patients in three health corporations.ResultsThe author found no significant differences among the provider groups in the consistency of diagnosis and treatment or postoperative complications as a result of primary treatment. The patients treated by DHATs had a mean age 7.1 years younger than that of patients treated by dentists, and the presence or adequacy of radiographs was higher among patients treated by dentists than among those treated by DHATs, with the difference being concentrated in the zero- to 6-year age group.ConclusionsNo significant evidence was found to indicate that irreversible dental treatment provided by DHATs differs from similar treatment provided by dentists. Further studies need to be conducted to determine possible long-term effects of irreversible procedures performed by nondentists.Clinical ImplicationsA need to improve oral health care for American Indian/Alaska Native populations has led to an approach for providing care to these groups in Alaska. The use of adequately trained DHATs as part of the dental team could be a viable long-term solution.     

Risk of adrenal crisis in dental patients: Results of a systematic search of the literature

BackgroundThe authors performed a systematic search of the literature to identify the frequency of, risk of experiencing and factors associated with adrenal crises in dental patients.MethodsThe authors searched PubMed and Ovid MEDLINE (1947-June 20, 2012) and Embase (1974-2012) for English-language articles related to cases of adrenal crisis in dentistry and extracted and analyzed data from the articles. The six authors determined whether the cases identified met a consensus definition of adrenal crisis.ResultsOf 148 articles identified in the initial screening, 34 articles were included in the final review, from which six cases met the criteria of adrenal crisis. The authors categorized four cases as “suggestive of adrenal crisis” and two cases as “consistent with adrenal crisis.” Risk factors were significant adrenal insufficiency, pain, infection, having undergone an invasive procedure, having received a barbiturate general anesthetic, and poor health status and stability at the time of presentation. The authors estimated risk to be less than one in 650,000 in patients with adrenal insufficiency.ConclusionsAdrenal crisis is rare in dental patients, with only six reports of it having been published in the past 66 years. Risk is associated with unrecognized adrenal insufficiency, poor health status and stability at the time of treatment, pain, infection, having undergone an invasive procedure and having received a barbiturate general anesthetic.Clinical ImplicationsRisk of adrenal crisis is reduced through proper evaluation of the patient, identification of risk factors and following appropriate preventive measures.     

Advancing infection control in dental care settings: Factors associated with dentists' implementation of guidelines from the Centers for Disease Control and Prevention

Background and OverviewThe authors set out to identify factors associated with implementation by U.S. dentists of four practices first recommended in the Centers for Disease Control and Prevention's Guidelines for Infection Control in Dental Health-Care Settings—2003.MethodsIn 2008, the authors surveyed a stratified random sample of 6,825 U.S. dentists. The response rate was 49 percent. The authors gathered data regarding dentists' demographic and practice characteristics, attitudes toward infection control, sources of instruction regarding the guidelines and knowledge about the need to use sterile water for surgical procedures. Then they assessed the impact of those factors on the implementation of four recommendations: having an infection control coordinator, maintaining dental unit water quality, documenting percutaneous injuries and using safer medical devices, such as safer syringes and scalpels. The authors conducted bivariate analyses and proportional odds modeling.ResultsResponding dentists in 34 percent of practices had implemented none or one of the four recommendations, 40 percent had implemented two of the recommendations and 26 percent had implemented three or four of the recommendations. The likelihood of implementation was higher among dentists who acknowledged the importance of infection control, had practiced dentistry for less than 30 years, had received more continuing dental education credits in infection control, correctly identified more surgical procedures that require the use of sterile water, worked in larger practices and had at least three sources of instruction regarding the guidelines. Dentists with practices in the South Atlantic, Middle Atlantic or East South Central U.S. Census divisions were less likely to have complied.ConclusionsImplementation of the four recommendations varied among U.S. dentists. Strategies targeted at raising awareness of the importance of infection control, increasing continuing education requirements and developing multiple modes of instruction may increase implementation of current and future Centers for Disease Control and Prevention guidelines.The findings and conclusions in this report are those of the authors and do not necessarily represent the official position of the Centers for Disease Control and Prevention, Atlanta.The authors thank Jon Ruesch, who when this study was conducted was the director, Survey Center, American Dental Association, Chicago, for his effort in the collection of the data for this research project.

Dental care access and unmet dental care needs among U.S. workers: the National Health Interview Survey, 1997 to 2003

BACKGROUND: Healthy People 2010 oral health objectives call for an increase in the proportion of adults who use the oral health care system annually. To assess progress toward this goal, the authors evaluated dental care utilization and the extent of unmet dental care needs of U.S. workers and their families. METHODS: The authors conducted sex-specific analyses by occupation of 135,004 U.S. worker participants in the nationally representative National Health Interview Surveys (NHIS) conducted from 1997 to 2003. RESULTS: The reported lack of oral health care within the preceding year ranged from 18.9 to 57.8 percent among male workers and from 17.6 to 50.0 percent among female workers. Sex-specific occupational groups with the highest rates of reported unmet dental care needs included male health service occupations (17.1 percent) and female construction and extractive trade workers (26.8 percent). CONCLUSION: There are significant oral health care underutilization and high rates of unmet dental care needs among many U.S. worker groups. Strategies to increase regular dental visits for U.S. worker groups reporting low dental care access and high dental need are paramount. CLINICAL IMPLICATIONS: Targeting strategic dental care access programs to identified U.S. worker groups reporting dental care access deficits can improve oral health.     

The effect of dental sealants on bacteria levels in caries lesions: a review of the evidence

BACKGROUND: Concern about inadvertently sealing over caries often prevents dentists from providing dental sealants. The objective of the authors' review was to examine the effects of sealants on bacteria levels within caries lesions under dental sealants. METHODS: The authors searched electronic databases for comparative studies examining bacteria levels in sealed permanent teeth. To measure the effect of sealants on bacteria levels, they used the log(10) reduction in mean total viable bacteria counts (VBC) between sealed and not-sealed caries and the percentage reduction in the proportion of samples with viable bacteria. RESULTS: Six studies--three randomized controlled trials, two controlled trials and one before-and-after study-were included in the analysis. Although studies varied considerably, there were no findings of significant increases in bacteria under sealants. Sealing caries was associated with a 100-fold reduction in mean total VBC (four studies, 138 samples). Sealants reduced the probability of viable bacteria by about 50.0 percent (four studies, 117 samples). CONCLUSIONS: The authors found that sealants reduced bacteria in carious lesions, but that in some studies, low levels of bacteria persisted. These findings do not support reported concerns about poorer outcomes associated with inadvertently sealing caries. CLINICAL IMPLICATIONS: Practitioners should not be reluctant to provide sealants-an intervention proven to be highly effective in preventing caries-because of concerns about inadvertently sealing over caries.     

An adverse event trigger tool in dentistry: A new methodology for measuring harm in the dental office

BackgroundThere is a dearth of knowledge about the type and frequency of adverse events (AEs) in dentistry. Current approaches to obtaining information rely on reviews of randomly selected records, which may not be the most efficient or effective methodology.MethodsInspired by the Institute for Healthcare Improvement's (IHI) global and outpatient trigger tools, which identifies records with characteristics (”triggers“) that are associated with AEs, the authors created the dental clinic trigger tool. The triggers included procedures for incision and drainage, failed implants and selected treatment patterns. The authors ran the trigger tool against six months of electronic health records data and compared its performance with that of a review of 50 randomly selected patient records.ResultsIn total, 315 records were triggered, 158 (50 percent) of which were positive for one or more AEs; 17 (34 percent) of the 50 randomly selected records were positive for at least one AE. The authors assigned each AE an IHI severity ranking. Most AEs caused temporary harm, but nine were considered to have caused permanent harm according to a modified IHI severity ranking.ConclusionsThe study results demonstrate the promise of a directed records review approach, as the dental clinic trigger tool was more effective in identifying AEs than was a review of randomly selected records.Practical ImplicationsAll dental practices should proactively monitor the safety of the care they provide. Use of the trigger tool will help make this process more efficient and effective.     

A usability evaluation of four commercial dental computer-based patient record systems

BackgroundThe usability of dental computer-based patient record (CPR) systems has not been studied, despite early evidence that poor usability is a problem for dental CPR system users at multiple levels.MethodsThe authors conducted formal usability tests of four dental CPR systems by using a purposive sample of four groups of five novice users. The authors measured task outcomes (correctly completed, incorrectly completed and incomplete) in each CPR system while the participants performed nine clinical documentation tasks, as well as the number of usability problems identified in each CPR system and their potential relationship to task outcomes. The authors reviewed the software application design aspects responsible for these usability problems.ResultsThe range for correctly completed tasks was 16 to 64 percent, for incorrectly completed tasks 18 to 38 percent and for incomplete tasks 9 to 47 percent. The authors identified 286 usability problems. The main types were three unsuccessful attempts, negative affect and task incorrectly completed. They also identified six problematic interface and interaction designs that led to usability problems.ConclusionThe four dental CPR systems studied have significant usability problems for novice users, resulting in a steep learning curve and potentially reduced system adoption.Clinical ImplicationsThe significant number of data entry errors raises concerns about the quality of documentation in clinical practice.     

Dental treatment intensity in frail older adults in the last year of life

BackgroundPalliative care focusing on pain and infection is recommended for patients who are terminally ill. It is difficult to implement this strategy in practice because of the lack of clear guidelines. The authors conducted a study to examine dental treatment provided to a group of long-term care (LTC) residents in the last year of life.MethodsThe authors retrospectively followed 197 LTC residents (60 years or older) in the last year of life to death. On the basis of the dental services patients received between the new patient examination and death, the authors categorized the patients into three groups: no care (NC), limited care (LC) and usual care (UC). The authors developed a multivariable continuation ratio logit model with shared regression coefficients across two logits to identify the factors associated with the end-of-life dental care pattern.ResultsThe authors found that 50.8 percent of the patients received NC before death. Among those who received treatment, 62.9 percent received UC, and 60.7 percent of the patients in the UC group had completed their treatment in the last three months of life. A three-month increment in survival and having dental insurance resulted in 1.74 (95 percent confidence interval [CI], 1.32–2.30) and 2.59 (95 percent CI, 1.03–6.52) times greater odds, respectively, of receiving some dental treatment before death. Neither survival nor dental insurance, however, was associated with dental care intensity in the last year of life (that is, UC versus LC).ConclusionsWhile most of the patients who were in the last year of life received insufficient dental care, comprehensive treatment was provided commonly to frail patients at the end of life, raising questions about quality of care.Practical ImplicationsPalliative oral health management needs to be revisited to improve quality of care for frail older adults at the end of life.     

Concordance between clinical practice and published evidence: Findings from The National Dental Practice-Based Research Network

BackgroundDocumenting the gap between what is occurring in clinical practice and what published research findings suggest should be happening is an important step toward improving care. The authors conducted a study to quantify the concordance between clinical practice and published evidence across preventive, diagnostic and treatment procedures among a sample of dentists in The National Dental Practice-Based Research Network (“the network”).MethodsNetwork dentists completed one questionnaire about their demographic characteristics and another about how they treat patients across 12 scenarios/clinical practice behaviors. The authors coded responses to each scenario/clinical practice behavior as consistent (“1”) or inconsistent (“0”) with published evidence, summed the coded responses and divided the sum by the number of total responses to create an overall concordance score. The overall concordance score was calculated as the mean percentage of responses that were consistent with published evidence.ResultsThe authors limited analyses to participants in the United States (N = 591). The study results show a mean concordance at the practitioner level of 62 percent (SD = 18 percent); procedure-specific concordance ranged from 8 to 100 percent. Affiliation with a large group practice, being a female practitioner and having received a dental degree before 1990 were independently associated with high concordance (≥ 75 percent).ConclusionDentists reported a medium-range concordance between practice and published evidence.Practical ImplicationsEfforts to bring research findings into routine practice are needed.     

Prenatal exposure to dental amalgam: evidence from the Seychelles Child Development Study main cohort

BackgroundDental amalgams contain approximately 50 percent metallic mercury and emit mercury vapor during the life of the restoration. Controversy surrounds whether fetal exposure to mercury vapor resulting from maternal dental amalgam restorations has neurodevelopmental consequences.MethodsThe authors determined maternal amalgam restoration status during gestation (prenatal exposure to mercury vapor [Hg⁰]) retrospectively in 587 mother-child pairs enrolled in the Seychelles Child Development Study, a prospective longitudinal cohort study of the effects of prenatal and recent postnatal methylmercury (MeHg) exposure on neurodevelopment. They examined covariate-adjusted associations between prenatal maternal amalgam restoration status and the results of six age-appropriate neurodevelopmental tests administered at age 66 months. The authors fit the models without and with adjustment for prenatal and recent postnatal MeHg exposure metrics.ResultsThe mean number of maternal amalgam restorations present during gestation was 5.1 surfaces (range, 1–22) in the 42.4 percent of mothers who had amalgam restorations. The authors found no significant adverse associations between the number of amalgam surfaces present during gestation and any of the six outcomes, with or without adjustment for prenatal and postnatal MeHg exposure. Results of analyses with the secondary metric, prenatal amalgam occlusal point scores, showed an adverse association in boys only on a letter- and word-identification subtest of a frequently used test of scholastic achievement, whereas girls scored better on several other tests with increasing exposure.ConclusionsThis study’s results provide no support for the hypothesis that prenatal Hg⁰ exposure arising from maternal dental amalgam restorations results in neurobehavioral consequences in the child. These findings require confirmation from a prospective study of coexposure to MeHg and Hg⁰.     

Updated recommendations for managing the care of patients receiving oral bisphosphonate therapy: An advisory statement from the American Dental Association Council on Scientific Affairs

Background and OverviewIn 2005, the American Dental Association (ADA) Council on Scientific Affairs convened an expert panel to develop clinical recommendations for dentists treating patients who are receiving oral bisphosphonate therapy. The Journal of the American Dental Association published the resulting report in 2006. This 2008 advisory statement is the first of projected periodic updates of the 2006 clinical recommendations.ConclusionThis 2008 advisory statement concludes, on the basis of a review of the current literature, that for patients receiving bisphosphonate therapy, the risk of developing bisphosphonate-associated osteonecrosis (BON) of the jaw apparently remains low. It also newly concludes that current screening and diagnostic tests are unreliable for predicting a patient's risk of developing the condition. This statement updates the 2006 recommendations regarding general dentistry, management of periodontal diseases, implant placement and maintenance, oral and maxillofacial surgery, endodontics, restorative dentistry and prosthodontics, and orthodontics.
