Saliva as a diagnostic tool to measure polycyclic aromatic hydrocarbon exposure in dental patients exposed to intimate partner violence (IPV).

BACKGROUND: Social habits such as tobacco use, alcohol consumption, and chemically contaminated diet contribute to poor oral health. Intimate Partner Violence (IPV) is a global public health epidemic which can exacerbate the prevalence of health conditions affecting a victim's lifespan. This study investigates using saliva as a biomarker for detecting levels of benzo(a)pyrene [B(a)P]; a toxicant present in cigarette smoke and barbecued meat in a population of IPV + female patients. METHODS: A cross-sectional IRB-approved study utilized 63 female participants (37 African Americans [AA], and 26 non-African Americans [NAA]), who provided consent for the study. Participants submitted samples of saliva, as well as questionnaires about demographics, health history, and a well-validated (IPV) screen. RESULTS: The prevalence of IPV was greater in AA compared to NAA. While the concentrations of PAHs/B(a)P detected in saliva of IPV samples in NAA were generally within the range of B(a)P reported for saliva from elsewhere, the concentrations were high in some IPV positive samples. Among the B(a)P metabolites, the concentrations of B(a)P 7,8-diol, B(a)P 3,6- and 6,12-dione metabolites were greater than the other metabolite in both AA and non-AA groups who were positive. CONCLUSION: Our study supports the use of saliva as a potential "diagnostic rheostat" to identify toxicants that may exacerbate/precipitate systemic disease in female victims of IPV. In addition, our study is the first to report that IPV may precipitate the accumulation of B(a)P in oral cavity that can alter inflammatory cascades and increase risk of poor health outcomes in this population of patients.

Knowledge of human papillomavirus among dental providers: A mixed methods study.

Dental professionals are encouraged by the American Dental Association (ADA) to recommend the HPV vaccine to eligible patients. To better understand their comfort level in following this recommendation, we conducted a mixed methods study of dentists and dental hygienists. A total of 173 providers were surveyed and 8 interviewed. The majority felt they had an important role in preventing HPV-related OPC and that they should educate their patients and encourage HPV vaccination. However, most providers had low knowledge about HPV and expressed a need to obtain more information on the topic. In particular, they desired information about the HPV vaccine, its connection to cancer and where to refer patients for vaccination. They also wanted access to visual aids to help them bring up the topic. This study demonstrates the need to develop and disseminate educational programs for dental providers so they can assist with efforts to raise HPV vaccination rates.

Role of oral and gut microbiome in nitric oxide-mediated colon motility.

Periodontal disease (PD), a severe form of gum disease, is among the most prevalent chronic infection in humans and is associated with complex microbial synergistic dysbiosis in the subgingival cavity. The immune system of the body interacts with the microbes as the plaque extends and propagates below the gingival sulcus. Once bacteria reach the gingival sulcus, it can enter the blood stream and affect various areas of the human body. The polymicrobial nature of periodontal disease, if left untreated, promotes chronic inflammation, not only within the oral cavity, but also throughout the human body. Alterations seen in the concentrations of healthy gut microbiota may lead to systemic alterations, such as gut motility disorders, high blood pressure, and atherosclerosis. Although gut microbiome has been shown to play a vital role in intestinal motility functions, the role of oral bacteria in this setting remains to be investigated. It is unclear whether oral microbial DNA is present in the large intestine and, if so, whether it alters the gut microbiome. In addition, polybacterial infection induced PD reduced nitric oxide (NO) synthesis and antioxidant enzymes in rodent colon. In this review, we will discuss the interactions between oral and gut microbiome, specifics of how the oral microbiome may modulate the activities of the gut microbiome, and possible ramifications of these alterations.

Elder Abuse in the African Diaspora: A Review.

BACKGROUND: As with many other populations, abuse of older adults is a growing problem across the Africa Diaspora. Modernization and urbanization are eroding the traditional values of respect for older adults. Also, older adults living in environments with limited social and economic resources, and having no means of economic support create a recipe for elder abuse and neglect. METHODS: This article reviews the current literature on the epidemiology, risk factors, and interventions used for elder abuse across the African Diaspora. RESULTS: Reports of elder abuse range from 24.9% to 81.1% across the Diaspora. Risk factors include cognitive and physical impairment, social isolation, lack of resources and widowhood. CONCLUSION: Community-based programs using the unique social networks of older populations of African descent can provide a venue to improve caregiver training and support, reinforce traditional filial and informal caregiving practices, increase the utilization of available governmental and institutional.

Cardiovascular Health Disparities in Underserved Populations.

African Americans are at increased risk for hypertension, hyperlipidemia, obesity, and diabetes, which contribute to the burden of cardiovascular disease (CVD). The disparities of CVD in underserved populations require targeted attention from primary care clinicians to eliminate. Primary care can provide this targeted care for their patients by assessing cardiovascular risk, addressing blood pressure control, and selecting appropriate intervention strategies. Using community resources is also effective for addressing CVD disparities in the underserved population.

Dental management in patients with hypertension: challenges and solutions.

Hypertension is a chronic illness affecting more than a billion people worldwide. The high prevalence of the disease among the American population is concerning and must be considered when treating dental patients. Its lack of symptoms until more serious problems occur makes the disease deadly. Dental practitioners can often be on the frontlines of prevention of hypertension by evaluating preoperative blood pressure readings, performing risk assessments, and knowing when to consider medical consultation of a hypertensive patient in a dental setting. In addition, routine follow-up appointments and patients seen on an emergent basis, who may otherwise not be seen routinely, allow the oral health provider an opportunity to diagnose and refer for any unknown disease. It is imperative to understand the risk factors that may predispose patients to hypertension and to be able to educate them about their condition. Most importantly, the oral health care provider is in a pivotal position to play an active role in the management of patients presenting with a history of hypertension because many antihypertensive agents interact with pharmacologic agents used in the dental practice. The purpose of this review is to provide strategies for managing and preventing complications when treating the patient with hypertension who presents to the dental office.

Interprofessional Collaborative Practice Models in Chronic Disease Management.

Interprofessional collaboration in health has become essential to providing high-quality care, decreased costs, and improved outcomes. Patient-centered care requires synthesis of all the components of primary and specialty medicine to address patient needs. For individuals living with chronic diseases, this model is even more critical to obtain better health outcomes. Studies have shown shown that oral health and systemic disease are correlated as it relates to disease development and progression. Thus, inclusion of oral health in many of the existing and new collaborative models could result in better management of chronic illnesses and improve overall health outcomes.

Conscious Intravenous Sedation in Dentistry: A Review of Current Therapy.

Several sedation options are used to minimize pain, anxiety, and discomfort during oral surgery procedures. Minimizing or eliminating pain and anxiety for dental care is the primary goal for conscious sedation. Intravenous conscious sedation is a drug-induced depression of consciousness during which patients respond purposefully to verbal commands. No interventions are required to maintain a patent airway, and spontaneous ventilation is adequate as well as cardiovascular function. Patients must retain their protective airway reflexes, and respond to and understand verbal communication. The drugs and techniques used must therefore carry a broad margin of safety.

Effects of Diabetes on Salivary Gland Protein Expression of Tetrahydrobiopterin and Nitric Oxide Synthesis and Function.

BACKGROUND: Xerostomia is defined as dry mouth resulting from a change in the amount or composition of saliva and is often a major oral health complication associated with diabetes mellitus (DM). Studies have shown that xerostomia is more common in females at the onset of DM. Evidence suggests that nitric oxide (NO) plays a critical role in healthy salivary gland function. However, the specific mechanisms by which NO regulates salivary gland function at the onset of DM have yet to be determined. This study has two aims: 1) to determine whether protein expression or dimerization of NO synthase enzymes (neuronal [nNOS] and endothelial [eNOS]) are altered in the onset of diabetic xerostomia; and 2) to determine whether the changes in nNOS/eNOS protein expression or dimerization are correlated with changes in NO cofactor tetrahydrobiopterin (BH4) biosynthetic enzymes (guanosine triphosphate cyclohydrolase-1 and dihydrofolate reductase). METHODS: Functional and Western blot studies were performed in streptozotocin-induced and control Sprague-Dawley female rats with DM (type 1 [t1DM]) using standardized protocols. Confirmation of xerostomia was determined by increased water intake and decreased salivary flow rate. RESULTS: The results showed that in female rats with DM, salivary hypofunction is correlated with decreased submandibular and parotid gland sizes. The results also show a decrease in NOS and BH4 biosynthetic enzyme in submandibular glands. CONCLUSIONS: These results indicate that a decrease in submandibular NO-BH4 protein expression may provide insight pertaining to mechanisms for the development of hyposalivation in DM-induced xerostomia. Furthermore, understanding the role of the NO-BH4 pathway may give insight into possible treatment options for the patient with DM experiencing xerostomia.

Periodontitis may contribute to poor control of hypertension in older adults.

Diabetes educators' knowledge, opinions and behaviors regarding periodontal disease and diabetes.

PURPOSE: The purpose of this study was to determine certified diabetes educators' (CDE) knowledge, behaviors and opinions about periodontal disease and diabetes. METHODS: A 33 item questionnaire was distributed to CDEs who provide counseling and education services to patients with diabetes. Questions were open and closed-ended and Likert-scale. A total of 298 CDEs participated in the survey. Descriptive statistics were utilized. RESULTS: Most (62%) agreed that CDEs need to collaborate with dental professionals in disease management and 84% indicated interest in an oral health component being added to their continuing education. Only 20% felt confident in providing an oral health screening to their patients, while 51% discussed oral health with their patients and 64% said they have referred a patient to a dentist within the past year. Most (79%) have not received formal oral health education. CONCLUSION: The findings indicate that CDEs are aware of and agree that there is a link between oral health and systemic health and that collaboration with the dental profession would be a positive outcome for their patients, as would oral health topics being added to their continuing education courses. By introducing inter-professional collaboration between dental professionals and CDEs, and adding an oral health component to CE courses, CDEs' ability to educate their patients regarding the oral/systemic link could improve.

Periodontitis and diabetes associations with measures of atherosclerosis and CHD.

OBJECTIVE: Diabetes has been linked with more severe periodontal disease and with coronary heart disease (CHD). The purpose of this study was to determine if periodontal infection was a significant modifier in the risk that diabetes poses for increased carotid artery intimal-medial wall thickness (IMT) and more advanced atheroma lesions as reflected in atherosclerotic plaque calcification measured by acoustic shadowing. METHODS AND RESULTS: Comparisons for analyses of cardiovascular outcomes were performed based upon periodontitis and diabetes status. Periodontitis was measured using pocket depth and attachment loss at six sites per tooth. Cross-sectional data on 6048 persons aged 52-74 years were obtained from the Dental Atherosclerosis Risk in Communities Study. Participants without diabetes (n=5257) were compared to those with diabetes (n=791). Dependent variables were thick IMT (>1 mm), presence of acoustic shadowing, and prevalent CHD. All models were adjusted for the following covariates: gender, age, race/center, LDL and HDL cholesterol, BMI, triglycerides, hypertension, smoking, income and education. For multivariate model building, all non-normally distributed variables were transformed and multivariable logistic regression analyses were performed to evaluate the relationship between periodontal infection, diabetes, and cardiovascular outcomes. Individuals with diabetes and with severe periodontitis were found to be significantly more likely to have IMT>1 mm [OR=2.2, (1.4-3.5)], acoustic shadowing [OR=2.5, (1.3-4.6)], and CHD [OR=2.6, (1.6-4.2)] compared to those without diabetes or periodontal disease. CONCLUSION: Results from this study suggest that among people with diabetes, periodontal disease may increase the likelihood of subclinical atherosclerotic heart disease and CHD.

North Carolina internists' and endocrinologists' knowledge, opinions, and behaviors regarding periodontal disease and diabetes: need and opportunity for interprofessional education.

The aim of this study was to determine the knowledge and practice behaviors of one state's internists and endocrinologists who treat patients with any type of diabetes. A thirty-five-item questionnaire was mailed to 1,000 internists and 115 endocrinologists in North Carolina. Questions were open and closed ended and Likert-scaled. Descriptive statistics and bivariate analysis were utilized. The response rate was 34 percent (N=378). The overall usable response rate was 23 percent (N=254). Over half of the respondents (66 percent) were males. Internists' and endocrinologists' knowledge about periodontal disease was high. The majority of the respondents agreed that physicians should be taught about periodontal disease (88 percent) and should be trained to screen for periodontal disease in their patients (78 percent). However, when asked if they are confident in providing an oral health screening for their patients, the responses were evenly distributed from strongly agree to strongly disagree. This study suggests that internists and endocrinologists have some knowledge about oral health and believe that there is a link between periodontal disease and diabetes mellitus; however, the majority do not have sufficient familiarity with the studies that link periodontal disease and diabetes mellitus. They agree with the idea of collaboration with dental professionals to reduce the number of patients at risk for developing periodontal disease. Perhaps the time is conducive to promote interprofessional education and collaboration between medical and dental health care providers to prepare for the future increase in patient and treatment needs.

Adequacy of training in oral cancer prevention and screening as self-assessed by physicians, nurse practitioners, and dental health professionals.

OBJECTIVE: To assess the educational preparedness of medical and dental professionals to reduce the burden of OPC through planning effective cancer control strategies such as reducing tobacco consumption, suggesting healthy lifestyle and diet, and performing early detection through screening examinations and appropriate follow-up. METHODS: Self-reported adequacy of training in oral and pharyngeal cancer (OPC) early intervention activities was compared among 4 health care provider groups in North Carolina. Pretested surveys were mailed to random samples of licensed professionals. RESULTS: Nearly all providers agreed that early detection improves 5-year survival rates from OPC. Compared with 567 medical providers (273 family physicians and 294 nurse practitioners), 1235 dental providers (584 dentists and 651 hygienists) were significantly less likely to feel adequately trained in tobacco and alcohol cessation and to palpate neck nodes, but were significantly more likely to feel adequately trained to perform oral cancer examinations. Among dental providers, those who felt they had adequate training in tobacco and alcohol cessation were significantly more likely to assess these risk factors on patient medical histories. CONCLUSIONS: Education is needed to prepare dental providers to undertake OPC prevention activities, whereas medical providers would benefit from enhanced oral examination skills to improve their performance in early detection.

North Carolina dental hygienists' oral cancer knowledge and opinions: implications for education.

BACKGROUND: Appropriately trained dental hygienists can participate in oral cancer (OC) control. METHOD: We assessed knowledge of risk factors, diagnostic procedures, and opinions regarding OC education among 651 dental hygienists practicing in North Carolina using a mail survey. We constructed regression models of factors influencing high knowledge levels. RESULTS: Most correctly identified tobacco and alcohol use as OC risk factors, and 52% felt their knowledge of OC was current; however, we identified gaps. Diagnostic knowledge was highest for those who were recent graduates or received continuing education in the last 5 years; 96% were interested in future continuing education. CONCLUSION: Increased OC education content in dental hygiene curricula and training programs for practicing hygienists is needed to enhance early detection of OC.

North Carolina dental hygienists' assessment of patients' tobacco and alcohol use.

PURPOSE: North Carolina is the 11th most populous state and ranks 14th among all states in the age-adjusted mortality rate for oral and pharyngeal cancer (OPC). This study assessed North Carolina dental Hygienists' knowledge of tobacco and alcohol use as OPC risk factors, assessment practices of tobacco and alcohol use in patient medical histories, and opinions regarding tobacco and alcohol cessation education. Characteristics of dental hygienists who screen for tobacco and alcohol use in medical histories were also analyzed. METHODS: A 40-item survey was mailed to a simple random sample of 1,223 dental hygienists from a registry of 4,076 licensed in North Carolina. Data were included from 651 completed surveys, giving an effective response rate of 57%. RESULTS: Most respondents correctly identified tobacco and alcohol use as risk factors for OPC. A majority assessed patients' tobacco and alcohol use. Less than 10% assessed no tobacco factors, while nearly 42% assessed no alcohol factors. A number of background and practice characteristics were found to be positively associated with tobacco and alcohol screening in patient medical histories. A majority agreed or strongly agreed that dental hygienists should be trained to provide tobacco and alcohol cessation education to their patients; however, few felt trained to provide such education. CONCLUSION: Improvements in knowledge regarding tobacco and alcohol use as OPC risk factors are needed. Future interventions might include educational programs for currently practicing dental hygienists and increased tobacco and alcohol cessation education in the professional entry-level dental hygiene curricula.

Knowledge of oral cancer risk factors and diagnostic concepts among North Carolina dentists. Implications for diagnosis and referral.

BACKGROUND: Dentists play a critical role in the early detection of oral and pharyngeal cancer (OPC). The authors administered a survey that assessed the level of knowledge among dentists regarding risk factors and diagnostic concepts. METHODS: In 2002, the authors mailed a 38-item, pretested survey to a random sample of 1,115 licensed dentists practicing in North Carolina. Three-level (low, medium, high) composite index scores for knowledge of risk factors and diagnostic concepts were created using previously developed scales. The authors formulated multivariable models for risk factor and diagnostic knowledge indexes. RESULTS: Of the 584 respondents, only 181 (31 percent) had consistent medium-to-high levels of knowledge on both highly correlated indexes. Dentists who had higher risk factor and diagnostic knowledge scores were significantly (P < .05) more likely to have heard of one or more diagnostic aids (odds ratio [OR], 2.7), to have graduated from dental school within the previous 20 years (OR, 1.8) and to have performed biopsies or referred five or more patients with suspicious lesions per year (OR, 1.7 and 1.5, respectively) than were less-knowledgeable respondents. CONCLUSIONS: More education is needed in dental schools, postgraduate programs and continuing education programs to enhance dental professionals' knowledge of OPC risk factors and diagnostic concepts. Such programs should include information about adjunctive diagnostic aids. PRACTICE IMPLICATIONS: Greater knowledge of risk factors and diagnostic concepts may result in more frequent patient referrals, biopsy procedures or both, thus aiding in the early diagnosis and treatment of patients with OPC.

Oral cancer knowledge and examination experiences among North Carolina adults.

OBJECTIVE: This study assesses knowledge of oral cancer risk factors, clinical signs, and oral cancer examination experience among North Carolina adults. METHODS: A statewide random digit dial, computer-assisted telephone interview was conducted in 2002. Data from 1,096 respondents, with a response rate of 62 percent, were poststratified to 2000 census data by sex, race, and age group to produce population-based estimates. Knowledge of one sign of oral cancer, four or more risk factors for oral cancer, and having ever had an oral cancer examination were compared in logistic regression models using normalized weights. RESULTS: Fourteen (95% confidence interval [CI] +/-2) percent of adults had never heard of oral or mouth cancer. Risk factor knowledge was high for 56 percent (95% CI+/-3) and associated in a logistic regression model with younger age, feeling personal factors cause cancer, and nonuse of snuff. One sign of oral cancer (sore/lesion, red or white patch in mouth, and bleeding in the mouth) was correctly identified by 53 percent (95% CI+/-3) with significantly more correct responses from younger people, nonsmokers, and some college education. Only 29 percent (95% CI+/-3) reported ever having had an oral cancer examination when this procedure was described. Most respondents reported exams performed by dentists. In a weighted logistic regression model, older age, being dentate, nonsmokers, alcohol users, and those with some college education were significantly more likely to report having ever had an oral cancer examination. CONCLUSIONS: Although there is moderate knowledge of signs and risk factors for oral cancer among North Carolina adults, knowledge deficits remain. Oral cancer examinations need to be increased, particularly among tobacco smokers.
