Use of dental care by HIV-infected medical patients

Alveolar bone loss is a significant contributor to tooth loss in dentate HIV+ patients: A retrospective study

BACKGROUND

The study objectives were to determine tooth loss prevalence and to investigate the relationship between tooth loss and potential risk factors among adult dentate HIV+ patients on newer antiretroviral therapy (ART) regimens.

METHODS

Health records of 450 human immunodeficiency virus (HIV)-infected individuals were surveyed. Eighty-eight records of dentate HIV+ individuals with full-mouth periodontal charting and intra-oral periapical radiographs were identified. We collected data on demographics, systemic risk factors, oral health, and HIV disease measures. Caries exposure and alveolar bone loss (ABL) were radiographically assessed.

RESULTS

Eighty-eight percent of patients showed tooth loss. Patients with ABL ≥15% had a higher number of missing teeth (p < .01). Stepwise regression analyses indicated that tooth loss was positively associated with age (β = 0.45, p < .01) and ABL (β = 0.39, p < .01). By contrast number of years on ART was negatively associated with tooth loss (β = -0.28, p < .05).

CONCLUSIONS

Tooth loss remains prevalent among HIV+ patients, and periodontal disease is a significant contributor. The number of years on ART seem to improve oral health behavior and reduce tooth loss.

Implications of HIV Disease for Oral Health Services

This paper, by means of a quality framework, reviews health services research in relation to people with HIV infection. The relevance of oral health care services to people’s needs is considered in terms of the goal of health services to reduce the burden of disease on the everyday life of the population. Dental services may therefore have a role in primary prevention in the HIV epidemic, passing on information about HIV and promoting health through the early diagnosis and treatment of oral disease. Effectiveness research of oral health care in HIV assesses the usefulness of oral diagnosis, whether care is safe, and whether treatment is clinically effective. Few data are available on the efficiency of services. People with HIV still have problems accessing dental care, due to the volume of care available in relation to their need and acceptability of care. Access problems in the US are compounded by social inequality. Health services research data are particularly sparse in resource-poor countries, and there is a need to translate the available information into treatment guidelines appropriate to these settings. The research community and funding agencies should place greater emphasis on the quality of oral health services for people with HIV.

(A1) Identification of Oral Health Care Needs in Children and Adults, Management of Oral Diseases

The workshop considered five questions reviewing the identification of international oral health care needs of children and adults, and the management of oral diseases in resource-poor countries: (1) What is the role of the dental profession in the management of the HIV-infected individual? (2) Identifying health care needs-What are the epidemiology and disparities of HIV-associated oral lesions in children from different continents? (3) How effective is HIV treatment in controlling oral diseases? (4) Could we develop basic inexpensive oral and dental care protocols for economically deprived HIV-infected patients? and (5) What is the best method of arranging resources to meet the oral health care needs of people with HIV disease? The consensus of the workshop participants was that there is a need to re-target research efforts to non-established market economy countries and prioritize research in these regions to children with HIV disease. It will be important to assess commonalities and variations in oral health needs across geographical and cultural boundaries, and research efforts should be centralized in resource-poor countries to support multi-center longitudinal standardized studies. It is essential that oral health research be integrated into other health care research programs, to make these research priorities and public health initiatives feasible.

Barriers and facilitators to dental care among HIV-Infected adults

Oral health problems can significantly compromise HIV-infected individuals' general health and well-being, yet many of them experience an unmet need for oral care. The barriers and facilitators of obtaining dental care in a sample of HIV-infected adults, all of whom were eligible for Ryan White Part A funding for their treatment, were investigated through qualitative interviews with HIV-positive individuals who had not received dental services in the prior 12 months (n = 44). Identified barriers were as follows: (1) dental anxiety and fear, (2) cumbersome administrative procedures, (3) long waits at the dental office, (4) problem focused care-seeking behavior, (5) transportation difficulties, (6) dentists' reluctance to treat people like them, and (7) psychological issues. Identified facilitating factors were as follows: (1) coverage for dental care, (2) being treated with respect and acceptance, and (3) having an assigned case manager or social worker. Many of the barriers uncovered in this qualitative study can be addressed and overcome by case management services, but other approaches are needed to address the additional psychological and stigma-related factors that are impeding access to oral healthcare in this population.

Effects of a Brief Case Management Intervention Linking People With HIV to Oral Health Care: Project SMILE

Objectives. Although people with HIV experience significant oral health problems, many consistently identify oral health as an unmet health care need. We conducted a randomized controlled trial to evaluate the impact of a dental case management intervention on dental care use. Methods. We evaluated the intervention according to self-reported dental care use at 6-, 12-, and 18-month follow-ups. Multivariable logistic models with generalized estimating equations were used to assess the effects of the intervention over time. Results. The odds of having a dental care visit were about twice as high in the intervention group as in the standard care group at 6 months (adjusted odds ratio [OR] = 2.52; 95% confidence interval [CI] = 1.58, 4.08) and 12 months (adjusted OR = 1.98; 95% CI = 1.17, 3.35), but the odds were comparable in the 2 groups by 18 months (adjusted OR = 1.07; 95% CI = 0.62, 1.86). Factors significantly associated with having a dental care visit included frequent physician visits and dental care referrals. Conclusions. We demonstrated that a dental case management intervention targeting people with HIV was efficacious but not sustainable over time. Barriers not addressed in the intervention must be considered to sustain its use over time.

HIV-related stigma in the dental setting: a qualitative study

PURPOSE

To explore the experiences and expectations of HIV-related stigma in dental settings.

METHODS

This was a cross-sectional study of 60 HIV+ adult volunteers. We conducted audio-recorded interviews; responses to four open-ended questions were analyzed qualitatively for theme and content.

RESULTS

Twenty-seven participants (45%) reported ever having anticipated being judged, stigmatized or treated with disrespect in a dental setting due to HIV status. Thematic response categories included concerns about: (i) receiving humane and respectful treatment, (ii) being judged or stereotyped and (iii) giving HIV to the dentist. Regarding hesitancy to visit the dentist, subjects equally endorsed fear of the dentist (35%) and concerns about confidentiality and receiving humane treatment (35%).

CONCLUSION

HIV+ individuals encounter many fears and concerns related to dental care; fear of the dentist and concerns about confidentiality and receiving humane treatment appear to be central issues. Dental providers should be aware of and better manage these issues.

The feasibility, acceptance, and key features of a prevention-focused oral health education program for HIV+ adults

Poor oral health is common in HIV+ adults. We explored the feasibility, acceptance, and key features of a prevention-focused oral health education program for HIV+ adults. This was a pilot substudy of a parent study in which all subjects (n = 112) received a baseline periodontal disease (PD) examination and provider-delivered oral health messages informed by the Information-Motivation-Behavioral Skills (IMB) Model. Forty-one parent study subjects were then eligible for the substudy; of these subjects, a volunteer sample was contacted and interviewed 3-6 months after the baseline visit. At the recall visit, subjects self-reported behavior changes that they had made since the baseline. PD was reassessed using standard clinical assessment guidelines, and results were shared with each subject. At recall, individualized, hands-on oral hygiene coaching was performed and patients provided feedback on this experience. Statistics included frequency distributions, means, and chi-square testing for bivariate analyses. Twenty-two HIV+ adults completed the study. At recall, subjects had modest, but nonsignificant (p > 0.05) clinician-observed improvement in PD. Each subject reported adopting, on average, 3.8 (± 1.5) specific oral health behavior changes at recall. By self-report, subjects attributed most behavior changes (95%) to baseline health messages. Behavior changes were self-reported for increased frequency of flossing (55%) and toothbrushing (50%), enhanced toothbrushing technique (50%), and improved eating habits (32%). As compared to smokers, nonsmokers reported being more optimistic about their oral health (p = 0.024) at recall and were more likely to have reported changing their oral health behaviors (p = 0.009). All subjects self-reported increased knowledge after receiving hands-on oral hygiene coaching performed at the recall visit. In HIV+ adults, IMB-informed oral health messages promoted self-reported behavior change, subjects preferred more interactive, hands-on coaching. We describe a holistic clinical behavior change approach that may provide a helpful framework when creating more rigorously designed IMB-informed studies on this topic.

A Community-based Oral Health Promotion Model for HIV Patients in Nairobi, East District in Kenya: a Study Protocol

General HIV-related orofacial lesions, most commonly oropharyngeal candidiasis, have a typical clinical appearance and can be recognised by members of the community. Although affected patients often experience pain leading to compromised eating and swallowing, barriers such as social stigma and lack of knowledge regarding available services may prevent them from seeking early care. Educating the community about these lesions through community health workers (CHWs) who are democratically elected community members may encourage individuals affected to seek early oral healthcare in the health facilities. A health facility (HF) is a health centre mainly run by clinical officers (CO), i.e. personnel with a 3-year medical training, and nurses. This study aims to evaluate the effect of a CHW training programme on: i) their knowledge and recognition of HIV-related oral-facial lesions at a community level; and ii) referral of affected patients from the community to the HFs.

Dental anxiety and the use of oral health services among people attending two HIV primary care clinics in Miami

OBJECTIVES

We examined factors associated with dental anxiety among a sample of HIV primary care patients and investigated the independent association of dental anxiety with oral health care.

METHODS

Cross-sectional data were collected in 2010 from 444 patients attending two HIV primary care clinics in Miami-Dade County, Florida. Corah Dental Anxiety Scores and use of oral health-care services were obtained from all HIV-positive patients in the survey.

RESULTS

The prevalence of moderate to severe dental anxiety in this sample was 37.8%, while 7.9% of the sample was characterized with severe dental anxiety. The adjusted odds of having severe dental anxiety were 3.962 times greater for females than for males (95% confidence interval [CI] 1.688, 9.130). After controlling for age, ethnicity, gender, education, access to dental care, and HIV primary clinic experience, participants with severe dental anxiety had 69.3% lower adjusted odds of using oral health-care services within the past 12 months (vs. longer than 12 months ago) compared with participants with less-than-severe dental anxiety (adjusted odds ratio = 0.307, 95% CI 0.127, 0.742).

CONCLUSION

A sizable number of patients living with HIV have anxiety associated with obtaining needed dental care. Routine screening for dental anxiety and counseling to reduce dental anxiety are supported by this study as a means of addressing the impact of dental anxiety on the use of oral health services among HIV-positive individuals.

Feasibility of implementing rapid oral fluid HIV testing in an urban University Dental Clinic: a qualitative study

Background

More than 1 million individuals in the U.S. are infected with HIV; approximately 20% of whom do not know they are infected. Early diagnosis of HIV infection results in earlier access to treatment and reductions in HIV transmission. In 2006, the CDC recommended that health care providers offer routine HIV screening to all adolescent and adult patients, regardless of community seroprevalence or patient lifestyle. Dental providers are uniquely positioned to implement these recommendations using rapid oral fluid HIV screening technology. However, thus far, uptake into dental practice has been very limited.

Methods

The study utilized a qualitative descriptive approach with convenience samples of dental faculty and students. Six in-depth one-on-one interviews were conducted with dental faculty and three focus groups were conducted with fifteen dental students.

Results

Results were fairly consistent and indicated relatively high levels of acceptability. Barriers and facilitators of oral fluid HIV screening were identified in four primary areas: scope of practice/practice enhancement, skills/knowledge/training, patient service/patient reactions and logistical issues.

Conclusions

Oral fluid HIV screening was described as having benefits for patients, dental practitioners and the public good. Many of the barriers to implementation that were identified in the study could be addressed through training and interdisciplinary collaborations.

Effect of Education of Primary Health Care Workers on HIV-related Oral Lesions in Nairobi East District

Background

An estimated 90% of HIV-infected people are likely to develop oral lesions in the course of HIV infection. Oro-pharyngeal candidiasis (OPC), an early marker for HIV-infection, can be diagnosed during an oral examination (OE). Primary healthcare (PHC) providers in Kenya are neither trained nor sufficiently equipped to perform this simple, cheap and non-invasive examination. The PHC system in Kenya offers an opportunity to integrate early recognition and management of oral lesions into general health care. This study aims to estimate the effect of a multifaceted intervention for PHC providers in training them to perform an OE. Specifically, our primary objective is to establish whether the intervention is effective in increasing: i) the frequency of early detection of HIV-related oral lesions; and ii) referral rates for HIV-testing.

Design and methods

The study has been designed in two parts: a retrospective clinical data record study and a prospective cohort study with pre-post control group design, carried out in 2 administrative divisions in Nairobi East district. The intervention group will receive one day of training on recognition of HIV-related oral lesions and other common oral conditions. Reminder sessions will be held at individual health facilities. Routine tally sheets will be used to record all patients with HIV-related oral lesions, dental caries and periodontal disease. A convenience sample of all the PHC in a division will be used. It will not be possible to blind investigators or assessors. Expected impact of the study for Public Health. Early recognition and treatment of HIV infection influences long-term survival rates and will reduce healthcare expenditure.

Perceived dental needs and attitudes toward dental treatments in HIV-infected Thais

Despite the advancement in highly active antiretroviral therapy and improved health status of HIV-infected individuals, dental problems are still affecting their life and well-beings. We aimed to establish the prevalence of oral and dental complaints among HIV-infected patients, the prevalence of delayed access to dental service, and factors related with delayed access to dental service. A cross-sectional study using self-report questionnaire completed by the HIV-positive subjects was conducted at the largest HIV research clinic in Thailand during 2009-2010. Of all 299 subjects (28.6% males, 71% females, and 0.4% sex change from male to female: ages ranged from 22 to 59 years [mean 36.7±5.53)]), 84.3% reported of having past or present illnesses or problems related to the dental or oral conditions. The most reported problems were dental hypersensitivity (93.3%), bleeding from the gum (92.1%), and having dental caries (65.9%). Two-hundred and forty-two subjects (80.9%) would not disclose their HIV status when seeing a dentist. The most cited reasons of such behavior were their personal right whether to reveal or not, and being afraid of not receiving dental treatment from the dentists or staffs (51.7 and 40.9%, respectively). It is important to note that HIV-subjects admitted to having fear of being discriminated by the dental staffs even if they trusted their dentists as having high morality. In conclusion, our HIV-subjects had good basic knowledge of oral health with regard to HIV infection, experienced common dental problems, and wished to have accesses to HIV-dental specialist services, if possible.

National estimates of the characteristics of individuals infected with HIV who are likely to report and receive treatment for painful bleeding gums

Painful bleeding gums may be associated with HIV infection. This study examined the characteristics of persons reporting the symptom "painful bleeding gums" and their likelihood of accessing care. The study population consisted of persons receiving care for HIV as part of the HIV Cost and Services Utilization Study (HCSUS). In this national population, 5.3% reported painful bleeding gums. Significant differences in reporting painful bleeding gums were found between Hispanics/Whites, oral health status, and presence of other symptoms. Compared to younger persons, those in the middle age group were more likely to seek treatment, while persons with the highest CD4 counts were more likely to seek treatment than those with the lowest CD4 counts. This study showed that reporting painful bleeding gums was a function of ethnicity, other symptoms, and perceived oral health, while seeking treatment for painful bleeding gums was related to age and CD4 counts. Dentists and other health care providers can have an active role in improving the quality of life of persons living with HIV by being aware of the relationships that exist between patients with HIV and painful bleeding gums.

Visually storying living with HIV: bridging stressors and supports in accessing care

This paper examines how visual narratives may bridge relational understandings between people living with HIV/AIDS (PLWH/A) and future oral health care providers. Borrowing from literature in participatory visual methods such as photo elicitation and photovoice, we explored how PLWH/A visually choose to represent their daily lives. This study uses a grounded theory action-oriented approach in examining the thematic analysis of 257 photos and 12 related reflective participant journals. Ten collaborative themes emerged from the participants' analysis of their photos. These themes of social support, places, family, staff, group, recovery tools, transportation, friends, medications and food exhibited the indivisible characteristics of stressors and supports commonly found in accessing care. Further researcher reflections also found three meta-themes of stigmatization, maintenance of positive mental health and the development of pride in managing one's health. PLWH/A need to share these visual themes of supports and stressors with future dental providers so that they may hopefully acquire an understanding of chronic illness that is more personalized and relationship centered rather than merely numeric and detached.

The comparison of root caries experience between HIV-positive patients and HIV-negative individuals in a selected Iranian population

OBJECTIVES

Human immunodeficiency virus (HIV) infection is a concerning problem in dentistry and HIV-infected patients may experience root caries due to different risk factors. The aim of this study was to find the prevalence of root caries in a selected Iranian HIV-positive population.

METHODS

One hundred and seven IV drug users, based on ELISA and Western Blot test, were divided into two groups: group 1: HIV-positive patients and group 2: HIV-negative individuals. According to the T-CD4(+) cell count, subjects in group 1 were placed in two subgroups: Moderate immunodeficiency (200 mm(-3) < T-CD4(+) cells <500 mm(-3)) and Severe immunodeficiency patients (T-CD4(+) cells <200 mm(-3)). Teeth were examined by an examiner under suitable light to detect any changes in colour, texture or contour. The values of DMFT, DMFS, decayed root surfaces and total decayed surfaces were calculated. Data were analysed by independent t-test and chi-squared test.

RESULTS

The mean DMFT, DMFS and decayed root caries in group 1 and 2 had no significant difference. The mean value of total decayed surfaces of HIV+ patients was significantly higher compared with HIV- individuals (P = 0.03). The comparison of all parameters between two subdivisions of group 1 showed no significant difference.

CONCLUSIONS

The results indicate that HIV+ patients experienced more dental caries, but not more root caries than healthy ones. Along with decreasing T-CD4(+) cell count, tooth caries' prevalence did not increase.

CLINICAL RELEVANCE

Based on our findings, root caries prevalence is almost the same in HIV-positive and negative individuals; however, it is necessary to decrease tooth caries by continual monitoring and periodic dental examination.

Utilization of dental care services among low-income HIV-positive persons receiving primary care in South Florida

We investigated the use of dental care services among a population of low-income persons living with HIV/AIDS who had not seen a dental care provider during the 12 months prior to study enrollment. A total of 593 participants were recruited from five HIV primary care clinics in two South Florida counties and interviewed regarding past utilization of dental care services, HIV primary care service utilization, and barriers to care. Multivariate logistic regression analysis was used to determine correlates of oral care utilization within the preceding two years. One-third of respondents reported seeing a dentist in the preceding two years. The odds of having seen a dentist were greater for respondents with stable housing, more than a high school education, and who had received help in getting dental care; black respondents (compared to Hispanics and non-Hispanic whites) were less likely to have seen a dentist in the preceding two years. Despite the availability of dental services for low-income HIV-positive persons, utilization of dental care remains low. This study reinforces the need to provide assistance to HIV-positive persons in obtaining dental care. In particular, it indicates that such assistance should be targeted toward Black Americans, persons with low income and unstable housing situations, and those with limited help to navigate the health care system.

HIV-positive patients' discussion of oral health with their HIV primary care providers in Miami, Florida

Over 90% of HIV-positive persons will have at least one oral manifestation of HIV disease during the course of infection. Clinical guidelines suggest that examination of the oral cavity should be included in initial and interim physical examinations of all HIV-infected patients by their HIV care providers. Clinically significant manifestations of oral disease may impact prescribed treatment regimens. The objective of this analysis was to describe HIV-positive patients' discussion of oral health and dental health with their HIV primary care providers and the correlates of this discussion. We used cross-sectional data from the baseline of a randomized trial testing the efficacy of a risk reduction intervention. Participants were HIV-positive male and female patients attending five HIV primary care clinics in Miami-Dade County, Florida, USA. Overall, 37% of patients did not discuss oral health with their provider. After controlling for age, gender, education, and clinic, odds of discussion of oral health for respondents with five or more primary care visits in the past year were half the odds of those with fewer visits (odds ratio (OR)=0.525, 95% confidence interval (CI): 0.336, 0.821). Odds of discussion for men reporting illicit drug use were 35% of that for non-drug using men (OR=0.353, 95% CI: 0.186, 0.671). Odds of discussion were 1.4 times greater for each additional health topic discussed (e.g., nutrition and smoking) (95% CI: 1.317, 1.544). Given that more than one-third of patients reported no discussion of oral health with HIV primary care providers in the past year, there is a need to increase the focus on oral health in the HIV primary care setting.

Utilization of dental health care services in context of the HIV epidemic- a cross-sectional study of dental patients in the Sudan

Background

HIV infected patients should be expected in the Sudanese dental health care services with an increasing frequency. Dental care utilization in the context of the HIV epidemic is generally poorly understood. Focusing on Sudanese dental patients with reported unknown HIV status, this study assessed the extent to which Andersen's model in terms of predisposing (socio-demographics), enabling (knowledge, attitudes and perceived risk related to HIV) and need related factors (oral health status) predict dental care utilization. It was hypothesized that enabling factors would add to the explanation of dental care utilization beyond that of predisposing and need related factors.

Methods

Dental patients were recruited from Khartoum Dental Teaching Hospital (KDTH) and University of Science and Technology (UST) during March-July 2008. A total of 1262 patients (mean age 30.7, 56.5% females and 61% from KDTH) were examined clinically (DMFT) and participated in an interview.

Results

A total of 53.9% confirmed having attended a dental clinic for treatment at least once in the past 2 years. Logistic regression analysis revealed that predisposing factors; travelling inside Sudan (OR = 0.5) were associated with lower odds and females were associated with higher odds (OR = 2.0) for dental service utilization. Enabling factors; higher knowledge of HIV transmission (OR = 0.6) and higher HIV related experience (OR = 0.7) were associated with lower odds, whereas positive attitudes towards infected people and high perceived risk of contagion (OR = 1.3) were associated with higher odds for dental care utilization. Among need related factors dental caries experience was strongly associated with dental care utilization (OR = 4.8).

Conclusion

Disparity in the history of dental care utilization goes beyond socio-demographic position and need for dental care. Public awareness of HIV infection control and confidence on the competence of dentists should be improved to minimize avoidance behaviour and help establish dental health care patterns in Sudan.

Oral manifestations of HIV infection in children and adults receiving highly active anti-retroviral therapy [HAART] in Dar es Salaam, Tanzania

BACKGROUND

The aim of the study was to compare the prevalence and types of HIV-related oral lesions between children and adult Tanzanian patients on HAART with those not on HAART and to relate the occurrence of the lesions with anti-HIV drug regimen, clinical stage of HIV disease and CD4+ cell count.

METHODS

Participants were 532 HIV infected patients, 51 children and 481 adults, 165 males and 367 females. Children were aged 2-17 years and adults 18 and 67 years. Participants were recruited consecutively at the Muhimbili National Hospital (MNH) HIV clinic from October 2004 to September 2005. Investigations included; interviews, physical examinations, HIV testing and enumeration of CD4+ T cells.

RESULTS

A total of 237 HIV-associated oral lesions were observed in 210 (39.5%) patients. Oral candidiasis was the commonest (23.5%), followed by mucosal hyperpigmentation (4.7%). There was a significant difference in the occurrence of oral candidiasis (chi2 = 4.31; df = 1; p = 0.03) and parotid enlargement (chi2 = 36.5; df = 1; p = 0.04) between children and adults. Adult patients who were on HAART had a significantly lower risk of; oral lesions (OR = 0.32; 95% CI = 0.22-0.47; p = 0.005), oral candidiasis (OR = 0.28; 95% CI = 0.18-0.44; p = 0.003) and oral hairy leukoplakia (OR = 0.18; 95% CI = 0.04-0.85; p = 0.03). There was no significant reduction in occurrence of oral lesions in children on HAART (OR = 0.35; 95% CI = 0.11-1.14; p = 0.15). There was also a significant association between the presence of oral lesions and CD4+ cell count < 200 cell/mm3 (chi2 = 52.4; df = 2; p = 0.006) and with WHO clinical stage (chi2 = 121; df = 3; p = 0.008). Oral lesions were also associated with tobacco smoking (chi2 = 8.17; df = 2; p = 0.04).

CONCLUSION

Adult patients receiving HAART had a significantly lower prevalence of oral lesions, particularly oral candidiasis and oral hairy leukoplakia. There was no significant change in occurrence of oral lesions in children receiving HAART. The occurrence of oral lesions, in both HAART and non-HAART patients, correlated with WHO clinical staging and CD4+ less than 200 cells/mm3.

Oral lesions as indicators of HIV infection among routine dental patients in Lagos, Nigeria

OBJECTIVES

To document the incidental oral lesions of human immunodeficiency virus (HIV) infection, the pattern and frequency of the lesions based on clinical presentation and oral manifestations in routine dental patients who tested positive in Nigeria.

SUBJECTS AND METHODS

The study was conducted at the Oral Diagnosis/Oral Medicine clinic of the Lagos University Teaching Hospital, Lagos, Nigeria between May 2002 and April 2003. During this period, all patients with oral lesions suggestive of HIV/acquired immunodeficiency syndrome (AIDS) as described in the EEC-WHO Classification and diagnostic criteria of oral lesions of HIV were counseled and offered voluntary HIV testing. All the 35 patients who consented and tested positive were included in this study.

RESULTS

Of a total of 700 patients 53 patients with oral lesions suggestive of HIV/AIDS were seen, thirty-eight (72%) consented to HIV screening, 15 patients (28%) refused. Thirty-five patients (92%), mean age 36 +/- 13 years were confirmed positive for HIV. Oral candidiasis was the commonest lesion seen (43%) the second common being Herpes zoster (23%). Other lesions seen included erythema multiforme in two (6%), facial palsy in two (6%) and oral hairy leukoplakia in one (3%).

CONCLUSION

An oral mucosal lesion may be the presenting lesion of HIV/AIDS in routine patients attending the dental clinic. Oral health care workers should practice optimal infection control based on the Centers for Disease Control 'Standard Precautions' guidelines on infection control for all patients to minimize occupational transmission of HIV.

Oral health findings for HIV-infected adult medical patients from the HIV Cost and Services Utilization Study

BACKGROUND

The HIV Cost and Services Utilization Study (HCSUS) was conducted by a consortium of private and government institutions centered at the RAND Corp. to provide national estimates of adult medical patients who are HIV-positive. This article presents descriptive oral health findings from that study.

METHODS

The National Opinion Research Center (NORC) conducted four interviews of a nationally representative sample of adults with HIV who made a medical visit for regular care in early 1996. This article uses data from the second interview conducted between December 1996 and July 1997. The authors constructed analytical weights for each respondent so the 2,466 interviewees represented a population of 219,700.

RESULTS

Most adult medical patients with HIV rated their oral health as at least "good," but 12 percent (representing a population of 25,300) rated it as "poor." Xerostomia was the most commonly reported symptom (37 percent) to arise in the time since the previous interview. Twenty-nine percent had a dental benefit under Medicaid and 23 percent had private insurance. Eighteen percent had not revealed their HIV status to the dentist they usually saw.

CONCLUSIONS

National data on adult medical patients with HIV provide a context for local or convenience sample studies and can help give direction to public health and public policy programs directed to the oral health needs of this population.

CLINICAL IMPLICATIONS

The attitudes and beliefs of adult HIV patients should be taken into account in the creation of community health education programs and continuing education for dentists. Medicaid programs should include adult dental benefits.

Factors associated with use of dental services among HIV-infected and high-risk uninfected women

OBJECTIVES

The authors explored the frequency of dental care utilization and identified the main barriers to access to dental care among U.S. women with HIV infection and uninfected women at high risk of becoming infected.

METHODS

The authors' prospective study included HIV-infected and uninfected women enrolled in the northern California and Chicago sites of the Women's Interagency HIV Study. A trained interviewer administered a standardized questionnaire to participants by phone. The authors explored subjects' utilization of dental care in relation to predisposing, enabling and need variables using both univariate and multivariate analyses.

RESULTS

The 363 participants were predominantly black and unemployed and had a history of using injected drugs. Not using dental care was most prevalent among HIV-negative women, particularly in Chicago. Multivariate analyses revealed that the strongest predictors of nonuse of dental care included being of a race other than white, fear of dentists and perception of poor or fair oral health.

CONCLUSION

Women not infected with HIV but at high risk of developing the infection appear to have even greater unmet dental needs than do HIV-positive women. Being of a race other than white and fear of dentists are strong predictors of not using dental care.

PRACTICE IMPLICATIONS

The Ryan White Comprehensive AIDS Resources Emergency Act facilitates dental care access for people who are HIV-positive, and is the likely explanation for the higher prevalence of dental care use in this group compared with uninfected women at high risk of becoming infected. This underscores the need for Medicaid to include dental coverage for low-income populations in all states.

Oral white patches in a national sample of medical HIV patients in the era of HAART

OBJECTIVES

Several types of HIV-related oral mucosal conditions have been reported to occur during the course of HIV disease progression. Of these, few may be manifested as 'white' lesions and many are noticeable to the patient. This paper examines the relationships between social, behavioral and medical aspects of HIV infection and reporting an occurrence of oral white patches (OWP) by HIV-infected patients.

METHODS

The subjects are participants in all three interviews in the HIV Cost and Services Utilization Study (HCSUS). The subjects were selected using a three-stage probability sampling design. The multivariate analysis is based on 2109 subjects with nonmissing binary outcome variable for all three waves representing a national sample of 214 000 individuals. The multivariate model was fitted using generalized estimating equations (GEE) by implementing the XTGEE command in STATA.

RESULTS

We estimate that 75 000 persons (35%) reported at least one incident of OWP, of these 14 000 reported having OWP during all three interviews, and that the rate of reporting declined over the three HCSUS waves. The multivariate analysis showed seven variables that were significant predictors of at least one report of OWP.

CONCLUSIONS

Compared with persons on HAART therapy, patients on other regimens or taking no antiviral medications were 23-46% more likely to report an incident of OWP. Compared with whites, African Americans were 32% less likely to report OWP, while current smokers were 62% more likely than nonsmokers. Being diagnosed with AIDS and having CD4 counts less than 500 significantly increased the likelihood of reporting OWP.

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.

Do regular dental visits affect the oral health care provided to people with HIV?

BACKGROUND

Financial factors related to income and insurance coverage have been found to limit access to, and influence use of, oral health care services by people with human immunodeficiency virus, or HIV.

METHODS

The authors determined if visiting a dentist regularly affected the oral health services provided to people with HIV when financial barriers were eliminated as an impediment to access. They analyzed dental claims data for services submitted for payment to the Minnesota Access to Dental Care Program. The analyses focused on comparisons of dental utilization patterns among 273 people classified as regular patients, or RPs, and 222 people classified as nonregular patients, or NRPs.

RESULTS

RPs were found to have been provided more diagnostic and preventive care, and less restorative, endodontic, periodontic, removable prosthodontic and oral surgical treatment than were NRPs. Although the mean submitted cost per patient visit was much higher for NRPs, total mean submitted costs per patient for RPs and NRPs were not significantly different. Even though NRPs underwent fewer procedures and had fewer clinic visits than did RPs, the procedures provided to NRPs were more complex and costly. As indicated by differences in the mix of dental care services provided to RPs vs. NRPs, continuity of primary oral health care for RPs led to a better oral health result at no increase in cost over that for NRPs.

CONCLUSIONS

The study findings provide substantial evidence regarding the value of regular oral health care for people with HIV.

CLINICAL IMPLICATIONS

This study reinforces the need for dentists to educate and encourage people with HIV to integrate regular oral health care into the ongoing maintenance of their overall health and well-being.

Effect of medical, drug abuse, and mental health care on receipt of dental care by drug users

We examined the association of patterns of health care in 1996 with subsequent dental care in 1997 or 1998 for 47,260 drug users enrolled in New York State Medicaid. From Medicaid files, we identified psychiatric care, prescribed antidepressants, a regular source of medical care, regular drug treatment (6+ contiguous months), and clinical conditions. Of this cohort, 58% received dental care. The adjusted odds ratios (AOR) of dental care were increased for drug users receiving psychiatric care and antidepressants (1.66 [1.55, 1.77]), psychiatric care alone (1.48 [1.41, 1.56]), or only antidepressants (1.18 [1.10, 1.27]), vs. neither. AORs of dental care were also higher for those with a regular source of medical care alone (1.27 [1.23, 1.35]) or with regular drug treatment (1.33 [CI 1.25, 1.41]) vs. neither. Mental health care and, to a lesser extent, a regular source of medical care and regular drug treatment may promote dental care in this vulnerable population.

Associations of self-reported oral health with physical and mental health in a nationally representative sample of HIV persons receiving medical care

BACKGROUND

The impact of oral health on HIV patients has not been sufficiently documented.

OBJECTIVE

To estimate the associations between measures of oral and generic health-related quality of life in persons receiving medical care for HIV.

DESIGN

This is a longitudinal study of interview data collected in a probability sample of adults with HIV receiving health care in the US. The data were collected at three points in time.

PATIENTS

Two thousand eight hundred and sixty-four HIV-infected adults using medical care.

MEASUREMENTS

Physical and mental health were assessed using 28 items and oral health was assessed using seven items on oral-related pain and discomfort, worry, appearance, and function. Clinical measures included CD4 count, oral symptoms, physical symptoms, and stage of HIV. Physical functioning and emotional well-being were measured on a 0-100 scale with higher scores indicating better health. Oral health was measured using seven items with a five point scale.

RESULTS

In multivariate analyses, oral symptoms had the strongest association with oral health-related quality of life. Each additional oral symptom was associated with an average decrease in oral health (0-100 possible range) of 3.97 points (p = 0.000). In addition, oral health was significantly associated with both physical and mental health. A one-point increase in oral health was associated with a 0.05 (p = 0.000) increase in mental health and 0.02 increase in physical health (p = 0.031).

CONCLUSIONS

Oral health is strongly associated with physical and mental health but provides noteworthy unique information in persons with HIV infection. Thus, physical and mental health measures of HIV patients should incorporate indicators of oral functioning and well-being.

A systematic review of complication risks for HIV-positive patients undergoing invasive dental procedures

BACKGROUND

This systematic literature review determined the strength of evidence regarding whether patients with human immunodeficiency virus, or HIV, are at higher risk of developing complications from invasive oral procedures than similar patients without HIV.

TYPES OF STUDIES REVIEWED

MEDLINE and EMBASE searches of the English literature from the early 1980s through April 2000 yielded five articles meeting the inclusion and exclusion criteria: original research, concurrent treatment of HIV-positive and HIV-negative subjects, presence of complications (for example, local or systemic infection, bleeding, alveolitis, delayed healing) resulting from extractions, orthognathic surgery, periodontal therapy, endodontic therapy, placement of dental implants, prophylaxis, or scaling and root planing.

RESULTS

The authors found no studies involving orthognathic surgery, periodontal therapy, dental implants, prophylaxis, or scaling and root planing, and only one study reporting few immediate endodontic therapeutic complications. Thus, the evidence is insufficient with respect to any additional risk associated with these procedures among people with HIV/AIDS. Because of the few studies, low overall complication rates and variability in results from different analytic approaches, the authors consider the evidence to be too poor to rule in or out a meaningful relationship between HIV status and complications from tooth extractions.

CLINICAL IMPLICATIONS

Limited published scientific evidence is available to guide clinicians in regard to possible increased risks of invasive oral procedures associated with the HIV status of the patient.
