A qualitative exploration of dental practitioners' knowledge, attitudes and practices towards HIV+ and patients with other 'high risk' groups

(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.

Oral Lesions of HIV Disease and HAART in Industrialized Countries

The epidemiology of HIV-related oral disease in industrialized nations has evolved following the initial manifestations described in 1982. Studies from both the Americas and Europe report a decreased frequency of HIV-related oral manifestations of 10–50% following the introduction of HAART (highly active antiretroviral therapy). Evidence suggests that HAART plays an important role in controlling the occurrence of oral candidosis. The effect of HAART on reducing the incidence of oral lesions, other than oral candidosis, does not appear as significant, possibly as a result of low lesion prevalence in industrialized countries. In contrast to other oral manifestations of HIV, an increased prevalence of oral warts in patients on HAART has been reported from the USA and the UK. HIV-related salivary gland disease may show a trend of rising prevalence in the USA and Europe. The re-emergence of HIV-related oral disease may be indicative of failing therapy. A range of orofacial iatrogenic consequences of HAART has been reported, and it is often difficult to distinguish between true HIV-related oral disease manifestations and the adverse effects of HAART. A possible association between an increased risk of oral squamous cell carcinoma and HIV infection has been suggested by at least three epidemiological studies, with reference to the lip and tongue. These substantial and intensive research efforts directed toward enhancing knowledge regarding the orofacial consequences of HIV infection in the industrialized nations require dissemination in the wider health care environment.

Knowledge and attitude toward human immunodeficiency virus/acquired immuno deficiency syndrome among dental and medical undergraduate students

Background and Objectives:

Human immunodeficiency virus (HIV) is a major public health challenge. Unjustified calls for the isolation of patients with HIV infection might further constrain the potential for expansion of clinical services to deal with a greater number of such patients. This infectious illness can evoke irrational emotions and fears in health care providers. Keeping this in view, a study was conducted to assess the knowledge and attitudes related to HIV/acquired immune deficiency syndrome (AIDS) among dental and medical students.

Methodology:

Descriptive cross-sectional survey of the entire dental and medical undergraduate students from two colleges was carried out using a pretested, self-administered questionnaire. Descriptive statistics such as percentage was used to present the data.

Results:

Ninety-eight percentage medical and dental undergraduate graduate students knew about HIV transmission in the hospital. Journals and internet were the leading source of information among both medical and dental undergraduates. The majority of respondents discussed HIV-related issues with their classmates. Surprisingly, 38% medical and 52% dental undergraduates think that HIV patient should be quarantined (isolation) to prevent the spread of infection. 68% medical and 60% dental undergraduates are willing to rendering dental/medical care to HIV-infected patients. Relatively large proportion (98%) of participants was willing to participate for HIV prevention program.

Conclusion:

The knowledge of medical and dental students is adequate, but the attitude needs improvement. Dental and medical students constitute a useful public health education resource. Comprehensive training, continuing education, and motivation will improve their knowledge and attitude, which enable them to provide better care to HIV patients.

Stigma and disclosure as barriers to regular dental care for people living with HIV/AIDS in Kwazulu-Natal and Western Cape, South Africa

Purpose

– The purpose of this paper is to determine the oral health care experiences of people living with HIV in Kwazulu-Natal (KZN) and the Western Cape (WC) and also to identify the role of stigma and discrimination in the oral health care experiences for people living with HIV in KZN and the WC.

Design/methodology/approach

– This study was a survey among HIV-positive people attending selected Community Health Centres and regional hospitals, HIV clinics in KZN and WC provinces in South Africa. The sample consisted of people living with HIV that were 18 years or older and who had given written, informed consent. A cross-sectional study structure has been employed using a standardized format using a semi-structured interview and an administered questionnaire to collect data. The study classified participants as living in metropolitan or non-metropolitan areas.

Findings

– Apprehension of loss of confidentiality, stigma and discrimination were the barriers that deterred participants from seeking care. Respondents stated that they feared what the dentist and staff would think of them being HIV positive and feared being discriminated against by the dentist and staff. In some instances there appears to be a difference between policy and practice regarding the oral health care needs of and services rendered to people living with HIV in public health facilities as there are still patients who do not obtain care and for whom the attitudes of the health care provider constitutes the major barrier to accessing that care.

Research limitations/implications

– The results are specific to KZN and WC and have to be extrapolated with caution to the rest of South Africa. Additionally, this study did not have a control group of HIV-negative people which would have enabled one to determine whether certain barriers were unique to people living with HIV.

Practical implications

– To make recommendations with respect to addressing the issue of stigma and discrimination in the oral health care experiences for people living with HIV in KZN and the WC as there is a definite need for the government to address the resource needs of rural areas and less developed areas of South Africa. Health care is a much-needed resource in these high prevalence areas and governments must ensure that all their HIV/AIDS projects and policies should have a rural component built into them.

Social implications

– This study emphasizes the importance of embracing people that are being discriminated and marginalized by society such as people living with HIV to ensure that they feel a franchised member of society who can take the initiative to be in control of their own health and, with the necessary aid from public resources and societal support, join forces to reduce the public health burden and its impact on the socio-economic milieu.

Originality/value

– To the best of the author's knowledge, there is no other study that has compared differences in the use of oral health care services by people with HIV in South Africa and these results serve as an indication of some the important issues in this regard.

Knowledge of and attitudes towards HIV/AIDS: a survey among dental students in Ajman, UAE

AIM

Encounters between dentists and patients with HIV/AIDS are bound to rise due to increased prevalence and emerging new treatments. This study assessed dental students' knowledge about transmission and oral manifestations of HIV/AIDS, and their attitudes towards patients regarding obligations to treat.

METHODS

Out of 109 students in 4 years of a 6-year dental undergraduate program, 106 responded to a questionnaire on knowledge of and attitudes towards HIV/AIDS. Knowledge and attitude scores were analyzed with Kruskal-Wallis one-way anova and the gender differences with the Wilcoxon signed-rank test.

RESULTS

The median score for students' overall knowledge was 39.5 (67%; maximum possible 59). The median knowledge scores for males and females were 38 and 40 respectively, although the difference was not statistically significant. The knowledge levels in Year 4 (42.5 ± 4.7), Year 3 (44 ± 6.5), and Year 2 (42 ± 5.8), were similar but significantly higher than in Year 1 (33 ± 7.9; P < 0.01). The median attitude score was 14 out of 24, with no significant differences within genders and years of study. Although the level of knowledge of the senior students was higher than that of the first years, the negative attitudes remained largely unchanged.

CONCLUSIONS

Appropriate educational programs may alter the misconceptions and the negative attitudes.

Biossegurança e odontologia: crenças e atitudes de graduandos sobre o controle da infecção cruzada

Este estudo teve o objetivo de investigar as percepções de graduandos de Odontologia sobre a fidelidade às diretrizes de biossegurança e acerca do preservar-se. Nove questões abertas, que abordaram aspectos de interesse para o tema, foram aplicadas em entrevista com 14 acadêmicos, que realizavam atendimento odontológico de pacientes da Faculdade de Odontologia de Araraquara da Unesp. Utilizou-se a metodologia de pesquisa qualitativa e a estratégia metodológica para análise das entrevistas foi a Discurso do Sujeito Coletivo (DSC). Três figuras metodológicas foram obtidas, sendo ideias-centrais, expressões-chave e o DSC propriamente dito. A análise dos discursos permitiu avaliar a fala natural da coletividade. Verificou-se a adesão dos entrevistados aos protocolos de biossegurança, embora houvesse a queixa de que, na rotina diária, as precauções fossem negligenciadas por não serem muito práticas. Entre as medidas de proteção individual e coletiva, rotineiramente utilizadas, foram apontados o uso de Equipamento de Proteção Individual (EPI) e as barreiras protetoras, bem como as atividades de desinfecção e esterilização. O risco de contágio foi visto por alguns com pavor e por outros com total indiferença porque acreditavam ser algo do qual é possível de se ter controle por meio da adesão às precauções padrão. Entre as doenças de maior preocupação, a aids e as hepatites B e C foram as mais temidas. Diante do discurso obtido, salienta-se a necessidade de se aperfeiçoar as estratégias educacionais, com intuito de motivar a fiel adesão às normas de biossegurança, essenciais no trato de pacientes odontológicos.

Access to dental care for HIV patients: does it matter and does discrimination exist?

A number of surveys highlight a shortage of dentists in the UK. There is also evidence of discrimination against those with HIV reported within the dental profession and service users. We decided to assess the extent of this problem in our HIV outpatients by conducting a cross-sectional survey, asking them to complete a questionnaire exploring issues related to dental care access, and using clients attending the routine genitourinary (GU) medicine outpatient clinic as controls. A total of 241 outpatients completed the survey, of whom 51 (21%) were HIV patients. Significantly, more HIV patients reported difficulty registering with a dentist than GU patients (58.8% versus 18.2%, chi(2) with Yates correction = 8.76, P = 0.0031). They also report significantly more dental health problems compared with controls (54.9% versus 32.1%, chi(2) with Yates correction = 8.02, P = 0.0046). In total, 34.6% of HIV patients who had declared their status to a dentist thought that it had negatively impacted on their care, with 6.2% being refused treatment. Our small survey confirms that discrimination in relation to access and level of dental care exists, with black African women being at most risk. Efforts are needed to raise professional standards and HIV awareness to prevent continuing inequalities in dental care provision.

Bridging a gap: the (lack of a) sociology of oral health and healthcare

This article provides an historical review of international research related to sociology and oral health and healthcare. I begin by considering the relevance of the mouth and oral health to social interactions and physical health, and outline existing inequalities in oral health and healthcare experiences. The paper examines critically some of the existing published research in the field - considering both what might be described as sociology of oral health and healthcare and sociology in oral healthcare - and demonstrates the dearth of sociological research related to this subject compared to other areas of interest within the field of sociology of health and illness. I conclude by suggesting some ways in which this area could be expanded and developed further. I suggest that sociological analyses of how individuals experience, understand and manage their mouth and oral health, can add to and enhance the broader field of the sociology of health and illness. Further, examining experiences and provision of oral healthcare may provide sociology with a new opportunity to explore the neglected field of private healthcare, but also to engage with health policy makers who seek to address oral healthcare needs.

The HIV positive dentist in the United Kingdom--a legal perspective

In 1991, the United Kingdom Advisory Panel (UKAP) was set up under the aegis of the Expert Advisory Group on AIDS (EAGA) to consider individual cases of HIV infected healthcare workers. Policy and guidance relating to HIV infected healthcare workers is set out in a Department of Health report. Although more recently the EAGA has advised that an HIV positive dentist may under certain conditions provide clinical treatment for patients who are also HIV positive, the advice from UKAP relating to exposure-prone procedures means, in effect, that dentists who become HIV positive must cease contemporary clinical dentistry. The plight of dentists who become HIV positive and face this situation has been poignantly described as '...the dental practice equivalent of clearing your desk and being escorted off the premises.'

Knowledge, attitudes, and practice of iranian dentists with regard to HIV-related disease

Of 369 registered dentists in Fars province in Iran, 309 (83.7%) responded to a survey regarding knowledge, attitudes, and practices related to human immunodeficiency virus (HIV) infection. The level of knowledge was low and was correlated with years in practice, hours worked per week, and whether additional work in a governmental dental office was performed; only the last was significantly associated with adherence to relevant infection control recommendations.
