A typology of models for expanding access to oral health care for people living with HIV/AIDS

Objectives: This article describes a typology of program models for expanding access to dental services for people living with HIV/AIDS (PLWHA). These programs serve communities with limited access and high unmet need for oral health care, such as rural areas, low‐income and racial/ethnic minorities. Methods: Interviews and site visits with dental and program directors were conducted at participating sites, including AIDS service organizations, community health centers, and university‐affiliated medical centers or hospitals. Results: Despite the differences across organizational structure, similar models and approaches were developed to engage and retain PLWHA in dental care. These approaches included: using mobile dental units; expanding the type and availability of previous dental services provided; providing training opportunities for dental residents and hygienists; establishing linkages with medical providers; providing transportation and other ancillary services; using dental case managers and peer navigators to coordinate care; and patient education. Conclusions: This typology can assist program planners, medical and dental care providers with service delivery strategies for addressing the unmet need for oral health care in their area.     

Access to dental care – experiences of men with HIV infection in the United Kingdom

Abstract – A piloted self-complete questionnaire enquiring about dental experiences was administered to a consecutive sample of men with asymptomatic HIV infection attending a dedicated clinic in London. Forty-seven men completed questionnaires. Despite a high level of dental attendance before diagnosis of HIV infection, 60% of the men had not visited a general dental practitioner since diagnosis. Nineteen men had visited a dentist since diagnosis; 15 had been refused or deterred by members of the dental team and 5 had attended without disclosing their HIV status. These data indicate that despite professional guidance to dentists, the perceptions of dentists held by people with HIV and the behaviours of dentists act as barriers to care. Dedicated dental clinics act as an important safety-net for people with HIV infection.     

Understanding the intention of dentists to provide dental care to HIV+ and AIDS patients

OBJECTIVE: The aim of this study was to understand the intention of dentists to provide dental care to HIV+/AIDS patients. METHODS: A representative sample of 791 dentists from the province of Quebec completed a questionnaire assessing their intention to provide dental care to individuals with HIV+/AIDS as well as their attitudes, perceived social norm, perceived behavioral control, perceived behavioral norm and personal normative belief regarding this behavior. Past experience with providing dental care (habit) to HIV+/AIDS patients, fear of AIDS and socio-demographic characteristics were also assessed. RESULTS: Overall, dentists have a strong intention to provide dental care to HIV+/AIDS patients. Nevertheless, 25% of the respondents expressed a low intention to provide dental care to these patients. The main factors explaining 71% of the variance in intention were perceived behavioral control (beta=0.52, P<0.0001), personal normative belief (beta=0.33, P<0.0001) and habit of treating HIV+/AIDS patients (beta=0.12, P<0.0001). CONCLUSION: To improve the motivation of dentists to treat HIV+/AIDS patients, emphasis should be placed on increasing self-efficacy to cope with the difficulties of providing dental care to HIV+/AIDS patients as well as on the importance of acting in agreement with the Dental Association's Code of Ethics.     

What influences dental students to serve special care patients?

This study examines factors associated with graduating dental students' motivation to deliver services to special care patients. We investigated community context and student characteristics, which would influence potential behavior. Higher percentages of older adults and low-income residents in the community were positively correlated with interest in serving special care populations. Factors which correlated with individual student characteristics included having a father with at least a college education, a higher number of weeks spent in extramural clinical rotations, preparedness to provide care to disabled patients, and service orientation and socially conscious attitudes. Frail elderly and disabled persons have limited access to dental care, which is compounded by a shortage of skilled dental professionals who are willing to treat these populations. Our findings suggest that interest in special care dentistry is partly conditioned by the dental school's demographic and dental market context. This study is important to dental educators and poli-cymakers because the challenge of providing care to the "special patient" will increase in the future.     

Dental and oral lesions in HIV infected patients: a study in Brazil

AIM: To determine the prevalence of dental and oral lesions, as well as treatment need, in a group of HIV sero-positive Brazilians. In addition, to test the association between oral manifestation of HIV infection and age, sex, mode of transmission and drug therapy. METHOD: All HIV seropositive patients attending a dedicated dental clinic in Recife were invited to participate in the study. They were all examined by one trained and calibrated examiner and interviewed by one trained interviewer. RESULTS: 161 of 204 patients (78.9%) agreed to participate in this study. Most of the participants were male (76%), had acquired HIV sexually (74.5%), and were taking some form of antiretroviral therapy (70.8%). 33.5% had one or more oral manifestation of HIV. Candidiasis was the most common (28.6%), followed by hairy leukoplakia (9.3%), Kaposi sarcoma (2.5%), ulceration (2.5%), herpes simplex (1.2%), papiloma (0.6%), and 4.4% had periodontal disease. Only 1.2% reported xerostomia. There were no differences in the prevalence of oral manifestations of HIV infection between age groups, sexes, modes of transmission and types of drug therapy (P>0.05). The mean DMF-T score was 19 (SD 8) and 78.9% needed some form of dental treatment. CONCLUSIONS: While the prevalence of oral manifestations of HIV/AIDS was low in this sample of HIV seropositive Brazilians, dental status was poor and need for dental treatment was high.     

Oral conditions and their social impact among HIV dental patients

This study aimed to assess oral health status and the social impact of oral conditions among dental patients with HIV infection in comparison with general dental patients receiving public-funded care in Adelaide, South Australia. DMFT and CPITN indices were recorded by one dentist at a clinic for HIV dental patients. The data were compared with information from an existing survey of general dental patients. Social impact was assessed using the Oral Health Impact Profile questionnaire and responses from HIV dental patients were compared with responses from a telephone interview survey of Adelaide residents. HIV patients were aged 21 to 49 years (median *** 34), 90.7 per cent were male and 29.6 per cent had stage 4 HIV infection. Oral candida was present among 32.0 per cent, hairy leukoplakia among 24.1 per cent, HIV gingivitis among 18.5 per cent, and HIV periodontitis among 33.3 per cent. The DMFT index and its components did not differ significantly between HIV and general dental patients, while CPITN scores were lower among HIV patients (p = 0.01). However social impact among HIV patients was frequent: 64.6 per cent reported toothache, 43.7 per cent avoided foods, and 16.7 per cent avoided going out because of dental problems. HIV patients reported significantly greater levels of social impact than the Adelaide sample (p < 0.01). Patients to this clinic frequently presented with severe and disabling oral conditions which were not adequately captured using standard clinical indices.     

The shortened dental arch concept and its implications for oral health care

The minimum number of teeth needed to satisfy functional demands has been the subject of several studies. However, since functional demands--and consequently the number of teeth needed--can vary from individual to individual, this minimum number cannot be defined exactly. In general, occlusion of a complete dental arch is preferable. However, this goal might be neither attainable, for general, dental or financial reasons, nor necessary. Many studies demonstrate that shortened dental arches comprising the anterior and premolar regions can meet the requirements of a functional dentition. Consequently, when priorities have to be set, restorative therapy should be aimed at preserving the most strategic parts of the dental arch: the anterior and premolar regions. This also implies that in cases of a shortened dental arch, the prompt replacement of absent posterior molars by free-end removable partial dentures leads to overtreatment and discomfort. The shortened dental arch concept is based on circumstantial evidence: it does not contradict current theories of occlusion and fits well with a problem-solving approach. The concept offers some important advantages and may be considered a strategy to reduce the need for complex restorative treatment in the posterior regions of the mouth.     

Perceived oral health status,unmet needs,and barriers to dental care among HIV/AIDS patients in a North Carolina cohort: impacts of race

OBJECTIVE: This prospective observational study examined differences in perceived oral health status, treatment needs, dental care utilization patterns, and barriers to care between HIV-infected non-Hispanic blacks and whites in North Carolina. METHODS: 632 adult HIV-infected medical clinic attendees provided information on their oral health status and dental care history during face-to-face interviews with a trained interviewer. RESULTS: Compared to whites, blacks were significantly more likely to be female, older, less educated, have lower income, and have acquired HIV by heterosexual sex or injecting drug use. Although two-thirds of patients reported good oral health, blacks were significantly more likely to have loose teeth, need extractions, and be episodic dental care utilizers. Primary barriers to dental care were cost (30%), fear (19%), and low motivation (13%). Sixty-five percent of patients had unmet dental needs in the last three years. Race, cost, fear, and immune competence were significantly associated with unmet dental need in a multivariable model. CONCLUSIONS: Disparities exist within this HIV-infected population in oral symptoms, utilization patterns, and perceived unmet dental need. Targeted interventions that address barriers to care are needed to help establish preventive dental care patterns in this region, especially among blacks.     

Applicability of SWOT analysis for measuring quality of public oral health services as perceived by adult patients in Finland

OBJECTIVE: To determine the applicability of SWOT analysis for measuring the quality of public oral health services from the adult client's perspective. METHODS: Data were collected using a structured questionnaire developed in an earlier study. The study group consisted of all adult (over 18 years of age) clients (n = 256) using public municipal oral health services in Kirkkonummi, Finland, during 2 weeks in 1995. Before treatment, patients filled out a questionnaire that measured the importance of their expectations in different aspects of oral care. After the appointment, they filled out a similar questionnaire that measured the enactment of these expectations in the treatment situation. The response rate was 51%. The difference between subjective importance and enactment of expectations was tested by Wilcoxon's signed rank test. Results were interpreted using both a conventional analysis of "expectation enacted or not" and SWOT analysis, which is used in strategic planning to identify areas of strengths (S), weaknesses (W), opportunities (O) and threats (T) in an organisation. RESULTS: In 28 statements out of 35, the two analyses revealed similar interpretations. In most areas the patient-perceived quality of the services was good. Weaknesses were found in the following areas: communicating to patients the causes and risk of developing oral diseases, informing them about different treatment possibilities, and including patients in decision-making when choosing restorative materials. CONCLUSION: SWOT analysis provided more structured interpretation of the results, and can be more easily transferred to development of services.     

Dental care of infectious patients in Denmark, 1986–1993: theoretical considerations and empirical findings

Abstract Changes in infection control and behavior and attitudes towards HIV-infected patients from 1986 to 1992/93 were studied among a random sample of 335 Danish dentists; previous studies among random samples of Danish dentists served as references. 249 (74.3%) returned a mailed questionnaire together with a time, steam, temperature (TST) control indicator strip processed in their steam autoclaves. 3.4% of the autoclaves had not sterilized properly, which was an insignificant decrease compared to 1986. Overall, infection control had improved since 1986. In 1992/93 17.3% of dentists surveyed reported use of gloves always: in 1986 0.8% did so. Many (60.2%) reported at least one needlestick or cut accident within the last year. The number of dentists who were willing to treat HIV-infected patients and the number of clinics that found they could treat infectious patients safely had increased from 56.1%, to 78.7%, and from 43.0% to 66.8%, respectively. Other attitudinal dimensions, for example views on secrecy of HIV test results and HIV screening policy, had not changed. A conceptual model based on the theory of reasoned action formed the framework for multiple logistic regression analysis with two different outcomes: Willingness to treat HIV-infected individuals and Treatment of HIV-infected patients. In particular, expected staff problems turned out to have a high explanatory value (odds ratio = 18.2) if HIV-infected patients were received. In both models Certainty about hygienic precautions had some explanatory value. The findings may give some clues about how to plan and implement future continuing education on infection control and attitudinal and behavioral aspects of caring for infectious patients.     

A review of satisfaction with dental service at a Jerusalem community clinic serving elderly patients

AIM: The audit of dental satisfaction and its association with the reported outcome of a dental health care programme for elderly patients. DESIGN: A telephone survey of 162 patients in a Jerusalem municipal dental clinic for geriatric patients, who had completed a treatment course in oral rehabilitation. RESULTS: The average age of the respondents was 73.2 +/- 8.45 years, over 80% of who were very satisfied or satisfied with the treatment given by the dental clinic staff. Only 1.8% were not satisfied (the remaining 17.9% were unable to answer the question). Among those who responded, 91.6% were currently using their full dentures, 80.4% reported an improvement in chewing ability, and 82.3% an improvement in appearance. Respondents who reported daily use of dentures and improved chewing and appearance, also reported higher levels of satisfaction with the clinic. CONCLUSIONS: These results indicate a potentially important role of satisfaction with dental staff in optimal compliance and success of a geriatric oral health care programme.     

HIV testing in the dental setting: A global perspective of feasibility and acceptability

HIV is no longer a death sentence with early diagnosis and effective treatment contributing to a good prognosis. Surveillance data, however, suggest that one in four people globally living with HIV are unaware of their HIV infection and remains at risk of transmitting their infection if having unprotected sex. A wider array of testing opportunities and settings are thus needed to address this issue of public health significance. Evidence suggests there is a role for the dental team, particularly dentists, in offering chairside point‐of‐care HIV screening to patients during their dental appointments. Dentists, dental hygienists, and other members of the dental team may still have a role in helping to identify new cases of HIV with the goal of improving health outcomes, addressing health inequalities and improving the quality and quantity of life. This paper reviews the global epidemiology of HIV/AIDS, summarizes the point‐of‐care HIV testing process, highlights key findings of international studies (from high‐, middle‐, and low‐income countries) on the role of dental professionals in point‐of‐care HIV testing, and offers suggestions for what additional evidence is needed to make point‐of‐care HIV testing a routine part of dental care.     

Dental care of HIV-infected patients: attitudes and behavior among Danish dentists

The aims of the study were to study Danish dentists' attitudes and behavior with regard to providing dental care to HIV-infected persons and to look for explanatory variables for the dentists' attitudes and behavior. Two hundred and twenty-eight Danish dentists responded to a questionnaire on dental treatment of HIV-infected patients and related problems (response rate: 91.2%). The dentists' attitudes differed a great deal from the current national policy as to where HIV-infected patients should be treated and with regard to the possibility of being tested for HIV anonymously. 64% of the dentists favored the idea of referral of HIV-infected patients to special dental clinics for routine dental treatment, and 93% disapproved of the idea that infected individuals themselves should decide whether they wish to inform their dentist or doctor of seropositivity. Older dentists were more reluctant to treat HIV-infected individuals than younger. Other differences with regard to a number of demographic variables were not found. No difference in attitude towards HIV-infected persons was found when compared to that towards HBV-infected individuals. The reluctance towards treatment of HIV-infected persons was present irrespective of any subsidy for an extra cost for treatment of HIV-infected patients.     

Results of offering oral rapid HIV screening within a dental school clinic

To broaden the availability of human immunodeficiency virus (HIV) testing, we offered rapid HIV screening tests to 811 patients attending a dental school for routine dental hygiene care. Study design is a prospective cross‐sectional study. The 319 (39.3%) agreeing to test, self‐identified as: Hispanic (34.4%), White (25.8%), African American (13.1%), Asian (8.3%), Native American/Pacific Islander (0.9%), more than one race/ethnicity (1.1%) or declining to state (16.5%). Over 35% (n = 113) were first time HIV test takers, with another 2.2% (n = 7) unaware of their testing history. Approximately 60% of the decliners choose “just don't want test today” as the reason. Following a strictly structured algorithm, four possible undiagnosed infections were initially identified, with one completing the algorithm to case confirmation. In conclusion, the confirmed incidence rate finding of HIV seropositivity of 0.31% found through initial screening at the dental clinic, compared with the 0.018% incidence rate of HIV with confirmed diagnosis in Los Angeles County, indicates that a rapid HIV screening test offered in a dental school clinic can potentially play an important role in discovering undiagnosed HIV individuals.
