Access to dental care in the United States

Efficacy, tolerability, and safety of an innovative medical device for improving oral accessibility during oral examination in special-needs patients: A multicentric clinical trial

Background

People with special needs have high unmet oral healthcare needs, partly because dentists find it difficult to access their oral cavity. The Oral Accessibility Spatula aims to improve oral accessibility. This prospective multicenter interventional open-label non-randomized patient-self-controlled trial assessed the ability of the spatula to improve the oral accessibility of special-needs patients during dental examinations.

Methods

The cohort was a convenience sample of minor and adult patients with special needs due to physical, intellectual, and/or behavioral disorders who underwent dental check-up/treatment in five French tertiary hospitals/private clinics in 2016–2018 and evinced some (Venham-Score = 2–4) but not complete (Venham-Score = 5) resistance to oral examination. After inclusion, patients underwent oral examination without the spatula and then immediately thereafter oral examination with the spatula. Primary outcome was Oral Accessibility Score (0–12 points; higher scores indicate visualization and probing of the tooth sectors). Secondary outcomes were patient toleration (change in Venham-Score relative to first examination), safety, and Examiner Satisfaction Score (0–10; low scores indicate unsatisfactory examination).

Results

The 201 patients were mostly non-elderly adults (18–64 years, 65%) but also included children (21%), adolescents (11%), and aged patients (3%). One-quarter, half, and one-quarter had Venham-Score = 2, 3, and 4 at inclusion, respectively. The spatula significantly improved Oral Accessibility Score (4.8 to 10.8), Venham-Score (3.1 to 2.6), and Examiner Satisfaction Score (3.4 to 7.2) (all p<0.001). There were no severe spatula-related adverse events.

Conclusion

The spatula significantly improved oral access, was safe and well-tolerated by the patients, and markedly improved oral examination quality.

Oral Health Practices, Beliefs and Dental Service Utilization of Albanian Immigrants in Milwaukee, Wisconsin: A Pilot Study

There is limited information on the oral health of Albanian immigrant population residing in the U.S. This creates a hinderance to developing and implementing appropriate dental care programs for the population. This study investigated oral health practices, beliefs, dental visits and associated factors of Albanian adults living in Milwaukee, Wisconsin. Purposive and snowball sampling methods were employed. Self-administered questionnaires were used to collect data on oral health practices, beliefs, dental visits and socio-demographic information. Descriptive and multivariable logistics regression were conducted. Overall, 266 adults were recruited, 54% male, 56% have lived 10 or more years in the U.S., 95% rated their oral health as excellent/good and 87% reported having a dental visit in the last year. Age, ability to speak English, having a usual source of dental care, and reporting excellent/good oral health were associated with having a dental visit in the last year. A substantial number of Albanians adult reported a dental visit in the last year and those that did not write or read in English had lower odds of reporting a dental visit.

[Access to dental services and related factors: a home-based population study]

The scope of this study was to identify factors associated with lack of access to dental services. It involved a cross-sectional study and a probabilistic complex sample by conglomerates in two stages with 857 participants over 18 years of age in a large city. Multiple analyses by means of logistic and multivariate regression in decision trees were made. The lack of access to dental services was considered a dependent variable. It was identified that 10.3% did not have access. In the multiple and multivariate analyses an association with age was verified and in the logistic regression a greater possibility of lack of access was found for each year of increased age, among those with the lowest per capita income and those who ranked appearance of teeth and gums as "fair/poor/very poor." The lack of access to dental services was greater among the most socially vulnerable. There is a pressing need to increase the allocation of public resources to promote health education and provide knowledge about how to access services when they are needed, focusing on dental care as a human right and ensuring that lack of access does not occur as users get older or among those with low income and also those dissatisfied with their oral appearance.

The Black dentist workforce in the United States

OBJECTIVES

The purpose of this paper is to describe the Black dentist workforce, the practice patterns of providers, and their contributions to oral health care for minority and underserved patients.

METHODS

A national sample survey of underrepresented minority dentists was conducted in 2012 and received a 32.6 percent response rate for self-reported Black dentists. Data were weighted for selection and response bias to be nationally representative. Descriptive and multivariable statistics were computed to provide a workforce profile of Black dentists. National comparisons are provided from published data.

RESULTS

Among all Black dentists (weighted n = 6,254), 76.6 percent self-identify as African-American, 13.2 percent as African, and 10.3 percent as Afro-Caribbean. The largest share of Black dentists are male, married, heterosexual, born in the United States and raised in a medium to large city. One third of Black dentists were the first in their family to graduate from college. Black dentists report higher average educational debt than all dental students, with graduates from International Dentist Programs having the greatest debt. Traditional practices (i.e., private practices) dominate, with 67.1 percent of Black dentists starting out in this setting and 73.5 percent currently in the setting. Black dentists care for a disproportionate share of Black patients, with an average patient mix that is 44.9 percent Black. Two in five Black dentists reported their patient pool is made up of more than 50 percent Black patients.

CONCLUSIONS

The underrepresentation for Black dentists is extraordinary, and the Black dentists that are in practice are shouldering a disproportionate share of dental care for minority and underserved communities.

Utilization of dental care among patients with severe mental illness: a study of a National Health Insurance database

Background

The oral health of patients with severe mental illness is poor, in general, and this may be attributed, in part, to inadequate dental care. This study investigated dental care utilization among patients with severe mental illness using a national representative sample.

Methods

This study used Taiwan’s National Health Insurance Research Dataset for 2009. Patients with the diagnosis of severe mental illness (ICD-9-CM: 290–298) were recruited as the study sample, and others comprised the control. Any visit to a dentist was defined as positive in terms of dental care utilization. Regression analyses were applied to determine the odds of dental care utilization for each diagnostic entity of severe mental illness, compared with the general population and controlling for potential covariates.

Results

Only 40 % of 19,609 patients with severe mental illness visited the dentist within 12 months. This was significantly lower than the dental visit rate of 48.3 % for the control population (odds ratio [OR] = .72, 95 % confidence interval [CI] = .69–.74; P <0.0001). The odds of dental care utilization differed among the severe mental illness diagnostic categories; e.g., the odds were lowest among those with alcohol psychoses (OR = .54, CI = .43–.68), senile dementia (OR = .55, CI = .52–.59) and other organic psychoses (OR = .58, CI = .52–.65), and highest among those with mood disorder (OR = .89, CI = .85–.94), with schizophrenic patients occupying a mid-level position (OR = .63, CI = .59–.67).

Conclusions

Patients with severe mental illness received less dental care than the general population. Health care providers and caregivers of patients with severe mental illness should encourage them to visit the dentist regularly, in order to improve the oral health of these vulnerable patient groups.

Safety analysis of tooth extraction in elderly patients with cardiovascular diseases

Background

This study aimed to evaluate the safety of tooth extraction in elderly patients with cardiovascular diseases.

Material/Methods

A total of 13 527 patients underwent tooth extraction at the Affiliated Ninth People’s Hospital of Shanghai Jiaotong University. Age, sex, and diseases were analyzed. Cardiac monitoring during tooth extraction was performed in 7077 elderly patients with hypertension and other chronic diseases, and the influence of various factors on safety of tooth extraction was evaluated. Additionally, 89 patients with primary hypertension were recruited, and electrocardiogram was monitored with a general monitor or a Holter monitor, and the detection rate of cardiovascular events was compared between the 2 groups.

Results

The elderly accounted from 75.3%, and patients aged 70–79 years had highest proportion. The most frequent comorbidities were hypertension, coronary heart disease, arrhythmia, cerebrovascular accident, and diabetes. In analysis of factors influencing the safety of tooth extraction in the elderly, a significant difference was noted in systolic blood pressure at different time points. In addition, change in heart rate was different between males and females. Detection rate of cardiovascular events by use of a Holter monitor was significantly higher than with a general monitor.

Conclusions

Hypertension was the most common comorbidity in elderly patients undergoing tooth extraction, followed by coronary heart disease and arrhythmia. Advanced age and increased comorbidity may increase the risk of complications. Risk score can be used to rapidly determine risk for complications during tooth extraction. The Holter monitor is superior to the general monitor in identifying cardiovascular events in high-risk elderly patients undergoing tooth extraction, and can be used in this population.

The association between geographical factors and dental caries in a rural area in Mexico

The aim of this study was to investigate the association between markers of oral disease and geographical factors influencing access to dental care (DMFT score) among school children in Central Mexico. Retrospective data were collected during an international service-learning program between 2002 and 2009. A sample of 1,143 children (55% females; mean age 12.7±13.1years) was analyzed. The mean DMFT score, represented largely by untreated tooth decay, was 4.02 (4.76). The variables that had the most significant effect on the DMFT score were proportion of paved roads between the community and dental services, and the availability of piped potable water. The DMFT score increased in proportion to the percentage of paved roads. In contrast, the DMFT score decreased with the availability of piped potable water. Similar results were found for untreated tooth decay. The main variable associated with a significant increase in dental fillings was proportion of paved roads. Together with Brazilian reports, this is one of the first investigations of the association between geographical factors and oral health in an underdeveloped setting.

Socio-economic inequalities and oral health in Canada and the United States

This paper describes and compares the magnitude of socio-economic inequalities in oral health among adults in Canada and the US over the past 35 years. We analyzed data from nationally representative examination surveys in Canada and the US: Nutrition Canada National Survey (1970-1972, N = 11,546), Canadian Health Measures Survey (2007-2009, N = 3,508), The First National Health and Nutrition Examination Survey (1971-1974, N = 13,131), and National Health and Nutrition Examination Survey (2007-2008, N = 5,707). Oral health outcomes examined were prevalence of edentulism, proportion of individuals having at least 1 untreated decayed tooth, and proportion of individuals having at least 1 filled tooth. Sociodemographic indicators included in our analysis were place of birth, education, and income. Data were age-adjusted, and survey weights were used to account for the complex survey design in making population inferences. Our findings demonstrate that oral health outcomes have improved for adults in both countries. In the 1970s, Canada had a higher prevalence of edentulism and dental decay and lower prevalence of filled teeth. This was also combined with a more pronounced social inequality gradient among place of birth, education, and income groups. Over time, both countries demonstrated a decline in absolute socio-economic inequalities in oral health.

Correlates of unmet dental care need among HIV-positive people since being diagnosed with HIV

OBJECTIVES

We analyzed the characteristics of people living with HIV/AIDS (PLWHA) who reported unmet oral health needs since testing positive and compared those characteristics with people reporting no unmet health needs. We also identified barriers to accessing oral health care for PLWHA.

METHODS

We collected data from 2,469 HIV-positive patients who had not received oral health care in the previous 12 months and who had accessed care at Health Resources and Service Administration-funded Special Projects of National Significance Innovations in Oral Health Care Initiative demonstration sites. The outcome of interest was prior unmet oral health needs. We explore barriers to receiving oral health care, including cost, access, logistics, and personal factors. Bivariate tests of significance and generalized estimating equations were used in analyses.

RESULTS

Nearly half of the study participants reported unmet dental care needs since their HIV diagnosis. People reporting unmet needs were more likely to be non-Hispanic white, U.S.-born, and HIV-positive for more than one year, and to have ever used crack cocaine or crystal methamphetamine. The top three reported barriers to oral care were cost, access to dental care, and fear of dental care. Additional reported barriers were indifference to dental care and logistical issues.

CONCLUSION

Innovative strategies are needed to increase access to and retention in oral health care for PLWHA. Key areas for action include developing strategies to reduce costs, increase access, and reduce personal barriers to receiving dental care, particularly considering the impact of poor oral health in this population.

The individual and program impacts of eliminating Medicaid dental benefits in the Oregon Health Plan

OBJECTIVES

We determined how elimination of dental benefits among adult Medicaid beneficiaries in Oregon affected their access to dental care, Medicaid expenditures, and use of medical settings for dental services.

METHODS

We used a natural experimental design using Medicaid claims data (n = 22 833) before and after Medicaid dental benefits were eliminated in Oregon in 2003 and survey data for continuously enrolled Oregon Health Plan enrollees (n = 718) covering 3 years after benefit cuts.

RESULTS

Claims analysis showed that, compared with enrollees who retained dental benefits, those who lost benefits had large increases in dental-related emergency department use (101.7%; P < .001) and expenditures (98.8%; P < .001) and in all ambulatory medical care use (77.0%; P < .01) and expenditures (114.5%; P < .01). Survey results indicated that enrollees who lost dental benefits had nearly 3 times the odds (odds ratio = 2.863; P = .001) of unmet dental need, and only one third the odds (odds ratio = 0.340; P = .001) of getting annual dental checkups relative to those retaining benefits.

CONCLUSIONS

Combined evidence from both analyses suggested that the elimination of dental benefits resulted in significant unmet dental health care needs, which led to increased use of medical settings for dental problems.

Secular trends in hospital emergency department visits for dental care in Kansas City, Missouri, 2001-2006

OBJECTIVES

We determined the trends, risk factors, and costs of emergency department (ED) visits for dental complaints during a six-year period in Kansas City, Missouri (KCMO).

METHODS

We used de-identified hospital discharge data from all facilities serving KCMO during 2001-2006. Using the International Classification of Diseases, Ninth Revision codes, we determined both counts and rates of ED visits related to toothache or tooth injury and analyzed the discharge diagnosis and costs of these visits. We used multivariable regression analysis to assess risk factors for the ED visits for dental complaints.

RESULTS

We found a significant increasing trend in dental complaint visits during the six-year period (from 13.1% to 19.0%, p < 0.01). Dental caries accounted for 20.4%, pulpitis or periapical abscess accounted for 14.8%, dental injury accounted for 8.7%, temporomandibular joint (TMJ) disorders accounted for 1.5%, and all other unspecified dental diseases accounted for 54.6% of the ED visits for dental complaints. The mean charge was approximately $360 per visit and was highest for TMJ disorders ($747) and lowest for unspecified other dental diseases ($277). Self-pay (38.3%) and Medicaid (32.3%) constituted the majority of the payment sources. Multivariable regression analysis indicated that self-payers, nonwhite people, adults, people with lower family income, and weekends were associated with increased use of ED visits for dental complaints.

CONCLUSIONS

There was a significant increasing trend in dental complaint-related ED visits. EDs have become an important site for people with dental problems to seek urgent care, particularly for individuals who self-pay or are on Medicaid.

Unmet dental needs in rural primary care: a clinic-, community-, and practice-based research network collaborative

BACKGROUND

Oral health is an essential component of general health and well-being, yet barriers to the access of dental care and unmet needs are pronounced, particularly in rural areas. Despite associations with systemic health, few studies have assessed unmet dental needs across the lifespan as they present in primary care. This study describes the prevalence of oral health conditions and unmet dental needs among patients presenting for routine care in a rural Oregon family medicine practice.

METHODS

Eight primary care clinicians were trained to conduct basic oral health screenings for 7 dental conditions associated with International Statistical Classification of Diseases and Related Health Problems 9-Clinical Modification codes. During the 6-week study period, patients older than 12 months of age who presented to the practice for a regularly scheduled appointment received the screening and completed a brief dental access survey.

RESULTS

Of 1655 eligible patients, 40.7% (n = 674) received the screening and 66.9% (n = 1108) completed the survey. Half of the patients who were screened (46.0%, n = 310) had oral health conditions detected, including partial edentulism (24.5%), dental caries (12.9%), complete edentulism (9.9%), and cracked teeth (8.9%). Twenty-eight percent of the patients reported experiencing unmet dental needs. Patients with dental insurance were significantly more likely to report better oral and general health outcomes as compared with those who had no insurance or health insurance only.

CONCLUSIONS

Oral health diseases and unmet dental needs presented substantially in patients with ages ranging across the lifespan from one rural primary care practice. Primary care settings may present opportune environments for reaching patients who are unable to obtain regular dental care.

Social Class Inequalities in the Utilization of Health Care and Preventive Services in Spain, a Country with a National Health System

In Spain, despite the existence of a National Health System (NHS), the utilization of some curative health services is related to social class. This study assesses (1) whether these inequalities are also observed for preventive health services and (2) the role of additional private health insurance for people of advantaged social classes. Using data from the Spanish National Health Survey of 2006, the authors analyze the relationships between social class and use of health services by means of Poisson regression models with robust variance, controlling for self-assessed health. Similar analyses were performed for waiting times for visits to a general practitioner (GP) and specialist. After controlling for self-perceived health, men and women from social classes IV-V had a higher probability of visiting the GP than other social classes, but a lower probability of visiting a specialist or dentist. No large class differences were observed in frequency of hospitalization or emergency services use, or in breast cancer screening or influenza vaccination; cervical cancer screening frequency was lower among women from social classes IV-V. The inequalities in specialist visits, dentist visits, and cervical cancer screening were larger among people with only NHS insurance than those with double health insurance. Social class differences in waiting times were observed for specialist visits, but not for GP visits. Men and women from social classes IV-V had longer waits for a specialist; this was most marked among people with only NHS insurance. Clearly, within the NHS, social class inequalities are still evident for some curative and preventive services. Further research is needed to identify the factors driving these inequalities and to tackle these factors from within the NHS. Priority areas include specialist services, dental care, and cervical cancer screening.

The utilization of dental care services according to health insurance coverage in Catalonia (Spain)

The aim of this study was to assess the relationship of dental care service use with health insurance and its evolution. The Catalan Health Interview Survey is a cross-sectional study conducted in 1994 (n = 15 000) and 2001-2 (n = 8400) by interviews at home to a representative sample of Catalonia (Spain). All the estimates were obtained by applying weights to restore the representativeness of the Catalonia general population. In the bivariate analysis, age, gender, social class and health insurance coverage were statistically associated with a dental visit in the previous year (P < 0.001). Analysis with logistic regression showed that health insurance status has a statistically significant association with utilization (P < 0.001), which was independent of the other socio-economic factors (age, gender, country of birth, and social class). However, the falling trend of differences by health insurance coverage is of note (adjusted OR = 2.2 and 1.5 at 1994 and 2002, respectively); as well as the positive evolution of the overall rate of dental service care use in the previous year, from 26.7% in 1994 to 34.3% in 2002. Future studies will be needed to monitor this tendency.

Influence of musculoskeletal conditions on oral health among older adults

Both musculoskeletal disorders and diseases of the oral cavity are common and potentially serious problems among older persons, yet little attention has been given to the links between them. Several musculoskeletal diseases, including osteoporosis, Paget's disease, and arthritic disorders, may directly involve the oral cavity and contiguous structures. Drugs used to treat musculoskeletal diseases, including corticosteroids and bisphosphonates, increase the risk of suppression of the immune system and osteonecrosis of the jaw, respectively. Many people with disabling osteoarthritis, rheumatoid arthritis, and other conditions have difficulty practicing good oral hygiene and traveling to dental offices for professional help. Various inexpensive measures can help such individuals, including education of their caregivers and provision of antimicrobial mouthwashes and special toothbrushes.

Socio-demographics of adult orthodontic visits in the United States

INTRODUCTION

Population-based studies in orthodontics have focused on differences between normative and perceived needs. However, information from national data on the prevalence of orthodontic visits and their associated factors in adults in the United States is scarce. We examined the demographic profile of likely adult users of orthodontic services and whether there is racial and ethnic disparity in orthodontic visits.

METHODS

We analyzed data from the Medical Expenditure Panel Survey, 2000-2004.

RESULTS

Overall, about 1% of the population reported an orthodontic visit. Subjects who made a general dental visit during the current year were significantly more likely to also have an orthodontic visit. Single adults, women, people between 18 and 30 years of age, and those from high-income families were more likely to report an orthodontic visit. There were no indications of racial and ethnic disparity for either black or Hispanic adults compared with white adults after adjusting for other covariates.

CONCLUSIONS

Substantial racial and ethnic disparity in adult orthodontic usage was not identified. Adults (ages 18-30 years), women, those with higher incomes, and single adults had significantly higher odds of reporting an orthodontic visit. However, additional studies specifically evaluating the association of treatment need among low-income families are required to evaluate whether these adults face significant barriers in accessing orthodontic care.

Cognitive function and dental care utilization among community-dwelling older adults

OBJECTIVES

We sought to investigate the relationship between varying levels of cognitive function and dental care utilization.

METHODS

Using data obtained from the National Health and Nutrition Examination Survey (1999-2002), we performed weighted descriptive and multivariate logistic regression analyses on 1984 individuals with at least 1 tooth and who were 60 years and older.

RESULTS

Multivariate analyses suggested that level of cognitive function was associated with dental care utilization. At a higher level of cognitive functioning, individuals were more likely to have had more frequent dental visits. In addition, a higher level of socioeconomic status, healthy lifestyle, and worse self-rated oral health-related symptoms were more likely to indicate a higher frequency of dental care utilization. By contrast, poorer oral health status as determined by clinical examinations was negatively associated with frequency of dental visits.

CONCLUSIONS

The results suggest that community-dwelling older adults with low cognitive function are at risk for less frequent use of dental care. Oral health serves as a mediating factor between cognitive function and dental care utilization. There is a great need to improve oral health awareness and education among older adults, caregivers, and health care professionals.

Effect of fear on dental utilization behaviors and oral health outcome

OBJECTIVES

This paper assesses the effect of fear on a number of dental utilization behaviors and oral heath outcome in a sample of adult Floridians.

METHODS

A telephone survey was conducted in 2004 among 504 adult Floridians. Data collected included sociodemographic factors, specific fear of dental pain (FDP), global FDP, global dental fear, three measures of dental utilization behaviors, and one measure of oral health outcome. Chi-squared tests and logistic regression analyses were conducted to quantify the individual and multivariate associations between fear factors and four behavior and outcome measures.

RESULTS

Global FDP was significantly associated with putting off making a dental appointment and approach to dental treatment. Global dental fear showed an independent negative impact on all four behavior and outcome measures; reports regarding specific fear of painful dental events were not significantly associated with four behavior and outcome measures.

CONCLUSIONS

Our findings suggest that: (i) dental fear and FDP have independent negative effects on dental utilization behaviors and oral health outcome after controlling for other sociodemographic and general health factors; and (ii) global dental fear encompasses broader components than FDP.

Oral health conditions of community-dwelling cognitively intact elderly persons with disabilities

OBJECTIVES

To present descriptive information on oral health and health care of community-dwelling elderly persons with disabilities who are living at home.

BACKGROUND

Most previous studies have focused on specific subpopulations, namely, persons who are essentially healthy and independent, are homebound, or are nursing home residents. Little information appears to be available on community-residing elderly persons with disabilities.

MATERIALS AND METHODS

A total of 641 participants aged 65 years and over in a Medicare Demonstration who were cognitively intact, completed an oral health questionnaire within 1 year of Demonstration entry. Demonstration participants were required to be living in the community, need or receive help with 2+ activities of daily living (ADLs) or 3+ instrumental ADLs (IADLs), and have recently experienced significant health services utilisation.

RESULTS

Subject mean age was 79.1 years, 73.8% were female, and 4% were minority. They were dependent in a mean of 1.8 ADLs and 2.9 IADLs. 43.1% reported that they had no natural teeth, 77.4% had dentures, 58.8% frequently felt their mouth was dry, 5.2% had jaw pain now and 6.1% had at some time experienced burning sensations in their mouth or tongue. 40.4% reported that they were currently in need of dental treatment, although 56.2% indicated they now had a dentist, and 42.1% identified having a dental visit within the past 12 months. 19.7% indicated some dental insurance coverage.

CONCLUSION

This is one of the first studies to focus on community-dwelling elderly people with disabilities. Substantial oral health morbidity was reported.

A decision analysis: the dental management of patients prior to hematology cytotoxic therapy or hematopoietic stem cell transplantation

There is a controversy regarding whether dental treatment before chemotherapy protocols, including hematopoietic stem cell transplantation (HSCT), is helpful to prevent infections during the consequent immunosuppression. The aim of this study was to develop a decision analysis framework that would test the effect of dental treatment prior to chemotherapy on the survival of the patient. A decision tree was created to compare the clinical outcomes of two treatment alternatives for a base-case patient receiving cytotoxics or undergoing HSCT. The variables used to build the model were "systemic infection", "unmet dental needs", "dental needs". The outcomes evaluate to compare the two strategies was "survival". We performed MEDLINE and PubMed searches of English-language literature according to a list of related terms. The decision analysis model selected dental treatment prior to chemotherapy as the preferred strategy for the base case analysis. The results of this study suggest that dental treatment prior to chemotherapy is the preferred treatment strategy. Using our base case data, 1.8 of every 1000 hemato-oncologic patients or HSCT patients will die compared to the non-treatment prior to chemotherapy strategy.

Oral Health in Veterans Affairs Patients Diagnosed with Serious Mental Illness

OBJECTIVES

We evaluated patient and medication treatment factors associated with self-reported oral health status in patients diagnosed with serious mental illness (SMI) in a large, national sample of patients in the Veterans Affairs (VA) health system.

METHODS

4,769 patients (mean age = 55, 7.8 percent women) were included from the VA's 1999 National Psychosis Registry (NPR) for whom the oral health information gathered by the VA's Large Health Survey of Veterans was available. Current (1999) psychotropic medication data were ascertained from the NPR. Multivariable logistic regression analyses were used to determine the patient factors (e.g., sociodemographic, enabling, and treatment factors) associated with poor or fair overall dental health, and with having tooth or mouth problems that made it difficult to eat.

RESULTS

While 61.0 percent of persons with SMI self-reported fair to poor dental health, 34.1 percent reported that oral health problems made it difficult for them to eat. Patients who were not employed, experiencing financial strain, who smoked, who were prescribed tricyclic antidepressants, or prescribed selective serotonin reuptake inhibitors were more likely to report poor or fair dental health. These variables were also associated with having tooth or mouth problems.

CONCLUSIONS

Suboptimal oral health was self-reported with substantial prevalence among patients with SMI, a problematic finding given its consequences for general health, social functioning, and quality of life. Greater efforts are needed to improve oral health outcomes among patients with SMI by facilitating access to dental care and addressing mutable factors such as smoking and medication side effects.

Access to care - what can the United States learn from other countries?*

This paper briefly describes the US system for dental care services; asserts that there is much to be learned by considering the experience of other countries; identifies a few lessons that may be learned from comparisons with England, Australia, and other nations; and encourages the monitoring of outcomes associated with innovations in financing and delivery of services elsewhere. Oral health is affected by more factors than access to dental care. Because so many factors at the individual, environmental, and delivery system levels affect oral health, interpreting the findings from international studies is difficult. Furthermore, the findings of these international studies are confounded by significant intra-country variation in outcomes and expectations. While public funding and the public provision of services (such as programs in schools or community health centers) can be powerful instruments of change, they have their limitations. Examination of all types of public subsidization of dental care may reveal inadvertent distributions that may increase disparities. The discovery of best practices and lessons learned in the financing and organization of dental care may begin by comparing US experiences with those of other countries.

Comparison of utilization of dental care services among Chinese- and Russian-speaking immigrant elders

OBJECTIVE

The purpose of the study was to identify factors predictive of use of dental services among Chinese- and Russian-speaking immigrant elders.

METHODS

The data for this analysis were collected from the 1997 survey "Assessing public health and health care needs of Russian-speaking elderly immigrants." A similar survey was replicated among Chinese-speaking elderly immigrants in 2000. Community-based samples of 300 Russian elders and 177 Chinese elders were recruited for the study.

RESULTS

Chinese elders used dental care services at lower rates than Russian elders. Education, length of stay in the U.S., social support, and smoking behavior were significant predictors for the use of dental services among Chinese. However, among Russian elders, age, income, and denture use predicted utilization of dental services.

CONCLUSIONS

Although Chinese- and Russian-speaking elders have similar immigrant experiences and share the same geographic location and urban setting, the two groups have different patterns of dental service use. These differences may be due to differences in socio-demographic characteristics, values, attitudes and knowledge of oral health and dental care, and unique cultural backgrounds.

Progressing toward a more culturally competent approach to dental care for African American elders

This study was conducted to understand perceptions that may influence oral self-care behaviors among elderly African American adults living in an urban community. Four focus groups at two senior centers were recruited, involving a total of 25 participants. Content analysis and ethnographic summaries were used to identify themes, common concepts and language. The results indicated that although the participants recognized the advantages of routine brushing, the importance of keeping teeth clean to prevent gum disease was not widely acknowledged. On the basis of these focus groups, the authors suggest that health promotion approaches for adults who are elderly should be linked to the audience's cultural norms and perceptions regarding the benefits of oral hygiene practices.

Institutional Barriers to Providing Oral Health Services for Underserved Populations in New York City

OBJECTIVES

We sought to explore institutional barriers to the provision of oral health services for the underserved among inner-city health centers.

METHODS

Mail-based survey of Medicaid-approved health centers in New York City without oral health services. The importance of four barrier categories was rated: resource issues, dental provider difficulties, referral problems, and low priority of dental care.

RESULTS

36 health centers completed the survey. The most important barriers were resource issues (66.7% agreed), dental provider difficulties (29.4%), referral problems (24.2%), and low priority (15.2%). Top individual barriers were lack of start-up funds (88%), lack of physical space (74%), lack of available funding sources (71%), and low reimbursement rates for dental services (69%). Most centers (78%) identified a need for dental services for their patients.

CONCLUSIONS

Access to oral health care remains a large problem for the underserved. Institutional barriers will need to be addressed to close the gap.

Coexistent concerns: assessing the social and health needs of dental clinic patients

University dental clinic professionals identified increasing numbers of patients with complex problems and generated 2 research questions: (1) Are there significant health and social concerns within the dental clinic population that indicate the need for high-risk screening and social work services?; and (2) How do age, gender, and income influence health and social concerns in this population? This exploratory descriptive cross-sectional study employed a brief self-report survey in a clinic waiting area. Logistic regression was used to understand the influence of age, gender and income on the existence of specific concerns. Results indicate that caregiving, finances and health are issues for 1/3 of the participants and that 44% endorsed 2 or more concerns. These findings were used to develop a routine high-risk screening tool for dental clinic patients and social work services within the clinic; they suggest that community clinics with dental services are an important place for identifying complex unmet needs.

Dental caries experience in northern Manhattan adolescents

OBJECTIVE

The study sought to document dental caries among adolescents residing in northern Manhattan, New York, by race, sex, and community.

METHODS

Clinical and demographic data were collected from children aged 12-17 years at five school-based dental clinics in northern Manhattan. Data on dental caries were collected by calibrated examiners using the National Institute of Dental and Craniofacial Research criteria for oral examinations.

RESULTS

A total of 566 children participated in the study. They were predominantly Hispanic (64%) or African American (28%). Compared to data from the National Health and Nutrition Examination Survey III, mean DMFT (3.36 vs 2.53; P<.01) and the prevalence of untreated disease (36% vs 16%; P<.01) were significantly higher for northern Manhattan adolescents. Of the adolescents evaluated, 13 percent had at least one severely carious tooth with pulpal involvement that required either extraction or endodontic therapy.

CONCLUSIONS

Adolescents in northern Manhattan have higher caries prevalence and higher levels of untreated caries than their national counterparts. Carious lesions progress to pulpal involvement in a high percentage of northern Manhattan children and require extraction or root canal therapy as treatment. There is an urgent need for affordable and available dental primary care services targeted to economically disadvantaged communities.

Oral health care utilization by US rural residents, National Health Interview Survey 1999

OBJECTIVE

To compare the dental care utilization practices of rural and urban residents in the United States.

METHODS

Data on dental care utilization from the 1999 National Health Interview Survey for persons 2 years of age and older (n=42, 139) were analyzed by rural/urban status. Percentages and 95 percent confidence intervals were calculated to produce national estimates for having had a visit in the past year, the number of visits, reasons given for last dental visit and for not visiting a dentist, unmet dental needs, and private dental insurance.

RESULTS

Rural residents were more likely to report that their last dental visit was because something was "bothering or hurting" (23.3% vs 17.6%) and that they had unmet dental needs (10.1% vs 7.5%). Urban residents were more likely to report having a dental visit in the past year (57.7% vs 66.5%) and having private dental insurance (32.7% vs 37.2%), compared to rural residents. There were no significant differences in most reasons given for not visiting the dentist between rural and urban respondents.

CONCLUSION

Dental care utilization characteristics differ between rural and urban residents in the United States, with rural residents tending to underutilize dental care.

Establishing a Dental Practice in a Rural, Low-Income County Health Department

Historically, county health departments have not been responsible for providing dental care to needy citizens. However, as the need for dental care among indigent and low-income citizens has grown health departments are being called on to provide these necessary services. This article describes one local board of health's effort to establish a dental program within a large rural county. The board of health directed the local county health department to purchase and operate a mobile dental clinic, build a permanent dental facility, recruit a dental staff, and most important, provide the financial resources to pay for the program.

Patterns of Endodontic Care for a Washington State Population

Endodontic care, provided by 3,402 dental offices, was assessed from claims data maintained by the Washington Dental Service for 1999. Approximately 5.7 million dental procedures were provided to 880,317 patients by 2,796 general practitioners, 105 endodontists, and 494 other specialists. Of all dental services, 63,321 (1%) were endodontic procedures involving 52,911 (6%) patients. General dentists, endodontists, and other specialists performed 64.7%, 33.7%, and 1.6% of endodontic procedures, the majority of which were root canal therapy. The most frequent tooth types treated by root canal therapy were mandibular first molars (17.0%), maxillary first molars (15.2%), mandibular second molars (11.8%), maxillary second bicuspids (10.3%), maxillary second molars (9.1%), maxillary central and lateral incisors (8.8%), and mandibular second bicuspids (8.0%). Direct and indirect pulp caps by generalists and conventional retreatment and surgical therapy by endodontists made up the majority of the remaining endodontic services. Men had a greater procedure rate than women for most endodontic procedures.

Dental complaints in emergency departments: a national perspective

STUDY OBJECTIVES

Using nationally representative data, we sought to describe the incidence of emergency department (ED) visits for dental-related complaints for children and adults in the United States. We hypothesized that dental-related ED visits were more likely than other ED visits to have Medicaid or no insurance as the payer.

METHODS

We used data from the 1997 to 2000 National Hospital Ambulatory Medical Care Survey, a national probability sample survey of hospital ED visits that is conducted by the National Center for Health Statistics. From these data, all ED visits in which one of the reasons for the visit was toothache or tooth injury were compiled and used to determine national estimates of counts and rates of ED visits for dental-related complaints. Logistic regression analysis on the outcome variable, presentation to the ED with a dental complaint (versus other problem), was performed to determine the association with payer and other covariates.

RESULTS

During the 4-year period from 1997 to 2000, there were an estimated 2.95 million ED visits in the United States for complaints of tooth pain or tooth injury, for an average of 738,000 visits annually. Population-based rates and proportion of all ED visits for dental complaints were highest in the 19- to 35-year-old group, accounting for 1.3% of all ED visits and 5.6 ED visits per 1,000 people in this age category. "Dental problem, not otherwise specified" was the most commonly assigned International Classification of Diseases, Ninth Revision, Clinical Modification diagnosis. Multivariate logistic regression results indicated that the adjusted odds of presentation to the ED for a dental complaint compared with other problems were significantly elevated for visits in which Medicaid or self-pay was listed as the payer relative to those with private insurance.

CONCLUSION

EDs are an important point of care for dental-related complaints, particularly for individuals who lack private insurance. ED providers should be equipped to triage, diagnose, provide basic treatment, and ensure appropriate follow-up care for dental problems, which may require enhancement of dental training for emergency medicine providers and improved dental care during and after ED visits.

Implementing a community-based oral health care program: lessons learned

OBJECTIVES

The objective of this paper is to report key findings of a process evaluation that may be useful to other institutions seeking to implement a community-based oral health care program primarily targeting children in dentally underserved communities. By partnering with community-based organizations, public schools, and community health care providers, the Columbia University School of Oral and Dental Surgery (SDOS) established the Community DentCare Network (DentCare) in the Harlem and Washington Heights/Inwood neighborhoods of northern Manhattan. These low-income neighborhoods are characterized by poor oral health and have been designated by the federal government as health professions shortage areas.

METHODS

The method used in the process evaluation was open-ended qualitative interviewing by a sociologist with extensive experience in this methodology aided by a participant-observer within the DentCare program.

RESULTS

The heterogeneity of the two communities required different strategies and resources to gain trust and acceptance. Fundamental changes were required of SDOS over a 10-year period, beginning with prioritizing community service into a primary mission. Collaborating with medical clinics facilitated the implementation of the network when the partners shared the same philosophical goals. Faculty and staff with different skills were needed during the start-up and the sustained development phases of the program.

Who shall care for the children of the poor and uninsured? Pediatric dentistry in the United States

Although Medicaid was established at least in part to help alleviate dental problems for children of the indigent, the program has not been particularly successful. Some possible solutions to the problem of disparities in access to pediatric dental care are suggested, including access and workforce approaches. Whatever approaches are undertaken, cost-benefit analyses should be done to demonstrate economic value.

Use of specific dental treatment procedures by dentate adults during a 24-month period

OBJECTIVES

To (a) describe the incidence of use of specific dental services; (b) test the hypothesis that certain predisposing, enabling, and need (PEN) factors are differentially predictive of service use; and (c) test the hypothesis that even with other PEN factors taken into account, race and household income are differentially predictive of certain dental services. Previously, this study identified PEN factors that predicted use of any care; herein we identify whether these same factors were differentially predictive of specific service use among users of at least one service.

METHODS

The Florida Dental Care Study was a longitudinal study of persons aged 45 years or older who had at least one tooth. Subjects participated for interviews and clinical examinations at baseline and 24 months later, with 6-monthly telephone interviews between those times.

RESULTS

Seventy-seven percent of subjects reported one or more visits. Results from a single multivariate multiple logistic regression suggested that even once analysis was limited to persons who used at least one dental service, at least one measure from each of the PEN domains was predictive of specific dental service use.

CONCLUSIONS

Each PEN domain was predictive of service use, even once limited to persons with at least one visit. Even with differences in other PEN variables taken into account, African-Americans were much less likely to receive dental cleanings, restorative dentistry and fixed prosthodontic services, and were much more likely to have a tooth extracted. Household income was predictive of receipt of fixed prosthodontic services, but not other service categories.

Met and unmet need for dental services among active drug users in Miami, Florida

This study considers both met and unmet need for dental services among chronic drug users in Miami, Florida, and compares them with non-drug users recruited from the same neighborhoods (N = 1,479). Three primary findings emerged: (1) dental problems are among the most frequently reported health problems, (2) drug use is independently associated with need for dental services, and (3) injection drug use is independently associated with increased odds of unmet need for dental services. These findings suggest that policies that increase access to dental services for drug users and other disadvantaged groups are needed. These services could be integrated into existing behavioral health programs already targeting active drug users.

Disparities in oral health and access to care: findings of national surveys

In this background paper, sociodemographic variables, including age, race, family income, sex, parental education, and geographic location, have been used to characterize the dental status of US children and their access to dental services. Because tooth decay, or dental caries, remains the preeminent oral disease of childhood and national data is available on dental office visits, tooth decay has been used as the primary marker for children's oral health, and visits to the dentist is the marker for care. In general, children from low-income families experience the greatest amount of oral disease, the most extensive disease, and the most frequent use of dental services for pain relief. Yet these children have the fewest overall dental visits. Paradoxically, children in poverty-those living in households with annual gross incomes under $16 500 for a family of 4-or near poverty-those in family households with incomes between $16 500 and $33 000-also have the highest rates of dental insurance coverage, primarily through Medicaid and SCHIP. For those most affected, dental disease is consequential for their growth, function, behavior, and comfort. The twin disparities of poor oral health and lack of dental care are most evident among low-income preschool children, who are twice as likely to have cavities as are higher income children. Medicaid-eligible children who have cavities have twice the numbers of decayed teeth and twice the number of visits for pain relief but fewer total dental visits, compared to children coming from families with higher incomes. Fewer preventive visits for services such as sealants increase the burden of disease in low-income children. These disparities continue into adolescence and young adulthood, but to a lesser degree. Disparities in oral health status and access to dental care are also evident when comparing black, Hispanic, and Native American children to white children and when comparing children of parents with low educational attainment to children of parents with higher educational attainment. The fastest growing populations of children are those that currently have the highest disease rates and the lowest amount of dental care. If the strong correlation between these subpopulations and dental diseases continues, caries rates are likely to rebound after longstanding declines, and the stress on publicly financed dental care will likely increase.

Oral health care in the 21st century: implications for dental and medical education

The past decade has been turbulent for dental education, marked by debate about the future directions of the curriculum and the profession itself. The bulk of the dental school curriculum is still devoted to tooth restoration or replacement techniques, although the need for these procedures has declined. Some dental educators now advocate an oral physician model as the desired direction for the profession, with expanded training in systemic disease pathophysiology and a practice scope that extends beyond exclusive focus on the teeth and supporting structures. Proponents of this model contend for curriculum time with faculty who desire to maintain a technical focus. The outcome of this curricular tug-of-war has implications for medical education, because many oral health problems now fall into the overlapping educational and patient care environments of physicians, dentists, and other health care providers. Will physicians perceive the new dentist as an encroachment on territory or as a resource to enhance patient care? Within dentistry, the traditions of tooth restoration and prosthodontics shape the profession's culture. Are dental educators ready to reconfigure a curriculum that is deeply intertwined with the professional identity of 150,000 U.S. dentists practicing today? To stimulate thinking about these issues, the authors analyze the responses of dental education to changes in the public's oral health and to calls for curricular reform, propose strategies for modifying the way dentists are prepared for their professional responsibilities, and explore the sociology of change in academic institutions, because elements of dental education targeted for reform are revered components of school culture.

Dental expenditures and source of payment by race/ethnicity and other sociodemographic characteristics

OBJECTIVE

This study presents race/ethnic-specific distributions of dental expenditures and their sources of payment by socioeconomic characteristics among US working-age adults.

METHODS

Data for persons aged 19-64 years from the 1987 National Medical Expenditure Survey (NMES) (n = 18,696) were used to calculate mean dental expenditures and their 95 percent confidence intervals.

RESULTS

Dental expenditures were reported by 44.5 percent of participants. Non-Hispanic whites and persons with higher income were more likely to report dental expenditures than their counterparts. Among persons reporting expenditures, those with lower income had lower expenditures than higher-income persons. No differences in the amount of expenditures by race/ethnicity, sex, or employment status were observed. In all race/ethnic groups almost half the expenditures were paid out-of-pocket and one-third by dental insurance.

CONCLUSION

While sociodemographic characteristics determined who had dental expenditures, they did not determine the amount or source of those expenditures.
