Compliance with infection prevention and control in oral health‐care facilities: a global perspective

Many publications are available on the topic of compliance with infection prevention and control in oral health‐care facilities all over the world. The approaches of developing and developed countries show wide variation, but the principles of infection prevention and control are the same globally. This study is a systematic review and global perspective of the available literature on infection prevention and control in oral health‐care facilities. Nine focus areas on compliance with infection‐control measures were investigated: knowledge of infectious occupational hazards; personal hygiene and care of hands; correct application of personal protective equipment; use of environmental barriers and disposable items; sterilisation (recirculation) of instruments and handpieces; disinfection (surfaces) and housekeeping; management of waste disposal; quality control of dental unit waterlines, biofilms and water; and some special considerations. Various international studies from developed countries have reported highly scientific evidence‐based information. In developed countries, the resources for infection prevention and control are freely available, which is not the case in developing countries. The studies in developing countries also indicate serious shortcomings with regard to infection prevention and control knowledge and education in oral health‐care facilities. This review highlights the fact that availability of resources will always be a challenge, but more so in developing countries. This presents unique challenges and the opportunity for innovative thinking to promote infection prevention and control.     

Perceptions of oral health: the South African Demographic and Health Survey of 1998.

Oral diseases are widespread in South Africa and affect large numbers of people in terms of pain, tooth loss, disfigurement, loss of function and even death. The majority of South Africans have no access to private services and are dependent on the government for oral health care services, but less than 10% of the population utilises public oral health services. This underutilisation is due to limited resources and inaccessibility. This article reports on the data collected on adults, 15 years and older, from the South African Demographic and Health Survey carried out in 1998, relating to perceptions of oral health. The questions dealt with oral health problems, utilisation of oral health services, loss of natural teeth, oral health practices and knowledge of water fluoridation. The results are discussed in terms of age, gender, education, place of residence, province and classification according to the previous population registration act. A high proportion (36%) of people had experienced oral health problems. Teeth problems were most commonly reported in the higher age groups, non-urban areas, Eastern Cape, Northern Cape and Free State, people with little education and those classified as non-urban Africans. Significant differences were found in regard to periodontal disease, tooth loss, knowledge of fluoride between groups according to age, geographic location, race and level of education. 62% of the respondents reported that they had lost some of their natural teeth and in some communities almost a third of the respondents were edentulous. In comparing the goals of the current draft national oral health policy with the findings of this survey the following implications for policy development should be noted: A higher priority needs to be given to oral health issues; Improve access by increasing primary health care facilities through the delivery of oral health care services; The high prevalence of hepatitis and HIV/AIDS infection poses a higher risk to oral health personnel and the public and The successful implementation of water fluoridation depends upon public knowledge, understanding and support.     

Job satisfaction among dental therapists in South Africa

Objectives: This article forms part of a larger research project on the dental therapy profession in South Africa. The objective of this study was to determine the level of job satisfaction among dental therapists trained at one South African university. Methods: This study was conducted using the qualitative research approach, where purposive and convenience sampling was used to select interviewees. They were asked a single question: “Do you think that dental therapists in South Africa are satisfied within their present careers?” The narrative data was interpreted using thematic analysis, and the data was validated by using the markers of trustworthiness. Results: All stakeholders believed that dental therapists trained at this university were not satisfied in the private and public sectors. In the private sector, they expressed frustration with their limited scope of practice. In the public service, lack of posts, poorly functioning dental facilities, and inadequate remuneration caused high levels of dissatisfaction. Many dental therapists chose this profession as a stepping stone to dentistry. Conclusions: The roles and scope of practice of all members of the oral health team needs to be redefined within the context of the primary health care approach. Universities need to recruit students appropriately to fulfill their role within this team. Dental services in the public sector need to be upgraded to meet the oral health needs of the country.     

Partnering globally and acting locally for infection control in Nepal

AIMS: To describe the process and outputs of an international collaborative oral health promotion project to develop a national infection control policy and training programme for oral health care workers in the low income country of Nepal between April, 2003 and May, 2004. METHOD: The project process was implemented in phases: 1) extensive review of national and international infection control documents; 2) development of draft infection control policies and protocols; 3) development of instruments to assess knowledge, attitude and behaviour and infection control practices; 4) baseline survey to assess these factors; 5) development of training programmes and training of oral health care providers; 6) revision of infection control policies and protocols, survey questions, assessment instruments, and training programme. OUTPUTS: Project outputs include a national infection control policy and protocols, infection control assessment instruments, infection control training materials and programmes, and oral health care providers trained in infection control. SUMMARY: The results of the project to develop a national infection control policy and training programme for oral health care workers in dental clinics, dental education institutions and the Nepal Primary Health Care System, required the collaboration of policy makers, health professionals, health managers, oral health care providers and educators from the government sector, private sector, Non-Government Organisations (NGOs) and International Non-Government Organisations (INGOs).     

Paediatric dental care during and post-COVID-19 era: Changes and challenges ahead

BackgroundCOVID-19 is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The virus is transmitted through respiratory droplets and by physical contact from contaminated surfaces to the mucosa. Its route of transmission has caused a significant challenge in medical and dental healthcare.ObjectiveThis article aims to review the literature and information available on the provision of paediatric dental treatment during and post-pandemic and to provide specific recommendations on the safe provision of paediatric dental care.ResultsChildren infected by SARS-CoV-2 have no or milder COVID-19 symptoms and are potential vectors in spreading the disease. Routine dental treatment is suspended in many countries because of the increased risk of cross-infection in dental practices. Only emergency dental care is provided for urgent conditions. It is necessary to gradually reinstate regular dental care to paediatric patients and maintain their good oral health. To control the disease transmission and maintain the oral health of the population, minimally intervention techniques that minimise or eliminate aerosol generation, plus comprehensive oral health preventive measures should be practised to safeguard safety at dental practices in this unprecedented time.ConclusionsRobust infection control guidelines should be implemented in dental clinics to minimise the risk of infection and to ensure the safety of patients and staff during the pandemic. Three levels of preventive care should be practised to prevent oral diseases and improve children's oral health in this COVID-19 era. Treatment should be prioritized to patients in urgent needs and aerosol-generating procedures should be minimized.     

Oral health in the context of primary care in Brazil

This article presents an integrative literature review that analyses the advances and challenges in oral health care of the Brazilian primary health care system, based on a political agenda that envisages re‐organising the unified health system (SistemaÚnico de Saúde – SUS). It is presumed that the actions suggested by the Alma‐Ata Conference of 1978 are still up‐to‐date and relevant when adapted to the situation in Brazil. Several studies and policies are reviewed, including works demonstrating the importance of primary care as an organising platform in an integrated health‐care network, Brazil's strategy for reorganising the primary care network known as the Family Health Strategy, and the National Oral Health Policy. This review discusses results obtained over the last twenty years, with special attention paid to changes in oral health‐care practices, as well as the funding of action programmes and assistance cover. The conclusion is that oral healthcare in the Brazilian primary health care system has advanced over the past decades; however, serious obstacles have been experienced, especially with regard to the guarantee of universal access to services and funding. The continuous efforts of public managers and society should focus on the goal of achieving universal coverage for all Brazilians.

Cultural factors and children's oral health care: a qualitative study of carers of young children

Objective: This qualitative study sought to identify cultural beliefs, practices and experiences that influence access to preventive oral health care for young children from different racial and ethnic groups. Methods: Four to six focus groups in each of the African–American, Chinese, Latino and Filipino communities in San Francisco, California were included in the study. Participants were carers of children aged 1–5 years. The 22 groups (n = 177 participants) were stratified by carer's age and, except in the African–American community, by whether US or non‐US born. Sessions were conducted in different languages as needed. Results: Lack of knowledge and beliefs about primary teeth created barriers to early preventive care in all groups. In Chinese groups more than others, health beliefs regarding disease causation and prevention influenced access to preventive dental care. In all groups, multiple family carers, especially elders, influenced access to preventive care. Dental fear, whether derived from prevailing community beliefs or personal negative dental experiences, greatly influenced attitudes regarding accessing preventive care. Conclusion: There are both similarities and differences between racial/ethnic groups in how cultural beliefs and experiences influence young children's access to dental care and how it might be improved.     

Illegal oral care: more than a legal issue

Affordable, safe and appropriate oral care, including preventive services, is not available for large parts of the world's population. In many low- and middle-income countries patients have to rely on a range of illegal oral care providers who are often socially accepted and part of the cultural context. Although filling a gap in service provision for poor populations, illegal provision of oral care is a serious public health problem, resulting in situations of low-quality care and risks for patients. It is a complex phenomenon going far beyond the legal context. It should be seen as a symptom of underlying health system and society deficits, ranging from lack of access to care and health inequities to problems of governance and law-enforcement. This paper analyses the problem based on the country case of Guyana, explores the public health, legal, professional, social, economical and ethical dimensions of the problem and proposes a differential view on illegal practice by grouping illegal oral care situations in four broad categories; each of them requiring different solutions to tackle underlying issues leading to the problem of illegal oral care.     

Impact of the Coronavirus on Providing Oral Health Care in the Netherlands

ObjectiveTransmission of SARS-CoV-2 during oral health care is potentially increased compared to regular social activities. Specific amendments to the Dutch national infection control guidelines were promulgated. This study aimed to map the impact of the coronavirus pandemic on providing oral health care during the first wave of the coronavirus pandemic in 2020 in the Netherlands.MethodsA cross-sectional web-based survey was sent via email to a representative sample of dental hygienists and dentists in the Netherlands.ResultsOf the 1700 oral health care practitioners approached, 440 (25.9%) responded to the survey. Patient access to oral health care was severely restricted during the lockdown in the spring of 2020. A total of 1.6% of the oral health care practitioners had laboratory-confirmed COVID-19 during the study period, although this is likely to be an underrepresentation due to limited access to testing at that time. Over half of the participants perceived an increased risk of virus transmission during aerosol-generating treatments in their practices. A large majority (65.0%–87.1%) of the oral health care practitioners followed the COVID-19-specific amendments to the national infection control guidelines. Compared to the pre-pandemic period, additional personal protective equipment and protocols were applied. Factors related with compliance with the additional recommendations were age, employment status, and occupation.ConclusionsThe pandemic had a profound impact on both the accessibility and practice of oral health care. This survey study found that most Dutch oral health care practitioners paid extra attention to hygiene and infection control. Also, a low number of COVID-19 infections detected amongst Dutch oral health care practitioners was reported in the Netherlands. These overall outcomes suggest that safe oral health care can be provided when following the current infection control recommendations.Key words: SARS-CoV-2, COVID-19, Dental infection control, Dental care, Dental practice management, Dentists     

Applying Andersen’s behavioural model to oral health: what are the contextual factors shaping perceived oral health outcomes?

Abstract – Objectives: Andersen’s revised behavioural model provides a framework for understanding the factors which influence utilization of health services and key health outcomes. To date, there have been few studies that have explicitly tested the model in relation to oral health. The aim of this study was to test the model and to examine the direct and mediated pathways between social, attitudinal and behavioural factors and perceived oral health outcomes. Methods: The model was tested in a general population sample with data from the UK adult dental health survey (N = 3815) using the two‐stage process of structural equation modelling. Results: Structural equation modelling indicated support in line with the hypotheses within the model; enabling resources (oral health education advice, type of dental service, finding NHS treatment expensive, dental anxiety) predicted need (number of decayed or unsound teeth and perceived treatment need); enabling resources and need predicted personal health practices and use of services (frequency of toothbrushing, recent dental attendance, attendance orientation) which, in turn, predicted perceived oral health outcomes (oral health quality of life). Both enabling resources and need also predicted perceived oral health outcomes. The impact of predisposing factors (social class, qualifications, income) on need, personal health practices and use of services, and oral health outcomes was indirect; that is, mediated by intervening factors. In the final model, 26%, 37%, 49% and 21% of the variance was accounted for in enabling resources, treatment need, personal health practices and use of services and perceived oral health outcomes respectively. Conclusion: The results provide support for Andersen’s behavioural model as applied to perceived oral health. Further conceptual development of the model is discussed.     

Impact of oral diseases on systemic health in the elderly: diabetes mellitus and aspiration pneumonia

Evidence is increasing that oral health has important impacts on systemic health. This paper presents data from the third National Health and Nutrition Examination Survey (NHANES III) describing the prevalence of dental caries and periodontal diseases in the older adult population. It then evaluates published reports and presents data from clinical and epidemiologic studies on relationships among oral health status, chronic oral infections (of which caries and periodontitis predominate), and certain systemic diseases, specifically focusing on type 2 diabetes and aspiration pneumonia. Both of these diseases increase in occurrence and impact in older age groups. The NHANES III data demonstrate that dental caries and periodontal diseases occur with substantial frequency and represent a burden of unmet treatment need in older adults. Our review found clinical and epidemiologic evidence to support considering periodontal infection a risk factor for poor glycemic control in type 2 diabetes; however, there is limited representation of older adults in reports of this relationship. For aspiration pneumonia, several lines of evidence support oral health status as an important etiologic factor. Additional clinical studies designed specifically to evaluate the effects of treating periodontal infection on glycemic control and improving oral health status in reducing the risk of aspiration pneumonia are warranted. Although further establishing causal relationships among a set of increasingly more frequently demonstrated associations is indicated, there is evidence to support recommending oral care regimens in protocols for managing type 2 diabetes and preventing aspiration pneumonia.     

A self-reported survey of Alzheimer's centers in Southwestern Pennsylvania

Directors of nursing at 23 nursing homes with Alzheimer's units in Southwestern Pennsylvania completed a self‐reported survey of 12 questions. Responses from the self‐administered questionnaires (100% response rate) revealed a wide variation in the staff categories assessing the oral health status of newly admitted residents with AD. The respondents described oral examinations that were incomplete when compared to the oral indicators listed in the Minimum Data Set. All nursing homes reported that oral hygiene was provided each day. The number of residents in a facility had a significant effect on the frequency of oral hygiene provided. Only 52% of the facilities reported yearly oral examinations for this population. According to the respondents, dental treatment was typically performed on‐site. The oral health care costs were paid by Medicare, Medicaid, the residents/family members, or by other undescribed resources. Insufficient time, staff, and training, as well as uncooperative behavior, were identified as barriers to optimum oral health care for residents with AD. Additional staff, specialized training, and increased government reimbursement were suggested to improve the oral health care for this group of older adults. For future studies, review of medical records and on‐site evaluation of the oral health care at these facilities should be required to verify the reported practices.     

Estimating COVID-19 prevalence and infection control practices among US dentists

BackgroundUnderstanding the risks associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission during oral health care delivery and assessing mitigation strategies for dental offices are critical to improving patient safety and access to oral health care.MethodsThe authors invited licensed US dentists practicing primarily in private practice or public health to participate in a web-based survey in June 2020. Dentists from every US state (n = 2,195) answered questions about COVID-19–associated symptoms, SARS-CoV-2 infection, mental and physical health conditions, and infection control procedures used in their primary dental practices.ResultsMost of the dentists (82.2%) were asymptomatic for 1 month before administration of the survey; 16.6% reported being tested for SARS-CoV-2; and 3.7%, 2.7%, and 0% tested positive via respiratory, blood, and salivary samples, respectively. Among those not tested, 0.3% received a probable COVID-19 diagnosis from a physician. In all, 20 of the 2,195 respondents had been infected with SARS-CoV-2; weighted according to age and location to approximate all US dentists, 0.9% (95% confidence interval, 0.5 to 1.5) had confirmed or probable COVID-19. Dentists reported symptoms of depression (8.6%) and anxiety (19.5%). Enhanced infection control procedures were implemented in 99.7% of dentists’ primary practices, most commonly disinfection, COVID-19 screening, social distancing, and wearing face masks. Most practicing dentists (72.8%) used personal protective equipment according to interim guidance from the Centers for Disease Control and Prevention.ConclusionsCOVID-19 prevalence and testing positivity rates were low among practicing US dentists. This indicates that the current infection control recommendations may be sufficient to prevent infection in dental settings.Practical ImplicationsDentists have enhanced their infection control practices in response to COVID-19 and may benefit from greater availability of personal protective equipment.

Transactions of an international conference. Worldwide concern: better dental care for more people. An international collaborative study. How social surveys were conducted.

It is assumed that utilization of dental care services and hence the state of oral health is dependent on social and psychological characteristics of both consumers and providers. The sociological variables studied included the basic facts of age, sex, residence and socioeconomic status. Attitudes to general health care, past oral health care and self assessment of oral health status were also investigated. Accessibility of oral health care facilities in terms of cost, loss of time and distance travelled was assessed, as was the consumers estimate of the dentist's sensitivity and competence, his attitude to preventive care, aesthetic values and knowledge of oral health care measures. Sociologists from the participating countries cooperated in the formulation of questionnaires which could be applied with comparable results despite differences in language and culture. Adults were interviewed in their own homes while younger groups completed the questionnaire in school under the supervision of the researchers. In all cases the sociological survey preceded the clinical examination to reduce the introduction of bias. The data were collected in Geneva and analysed to determine the extent to which oral health status could be related to perception of need, personal oral health practices, availability, accessibility, acceptability and utilization of services. Further analysis may help to determine whether observed differences between populations relate more to the characteristics of the systems of dental care or to features inherent in the population of the country.     

African countries propose a regional oral health strategy: The Dakar Report from 1998

It is clear that the African region faces a number of serious oral diseases, either because of their high prevalence or because of the severe tissue damage or death that can occur. Previous approaches to oral health in Africa have failed to recognise the epidemiological priorities of the region or to identify reliable and appropriate strategies to assess them. Efforts have consisted of an unplanned, ad hoc and spasmodic evolution of curative oral health services. This document focuses on the most severe oral problems that people have to live with like noma, oral cancer and the oral consequences of HIV/AIDS infection. It proposes a strategy for assisting member states and partners to identify priorities and interventions at various levels of the health system, particularly at the district level. The strategy aims at strengthening the capacity of countries to improve community oral health by effectively using proven interventions to address specific oral health needs. The strategy identifies five main 'programmatic areas', including (i) the development of national oral health strategies and implementation plans, (ii) integration of oral health in other programmes, (iii) delivery of effective and safe oral health services, (iv) regional approach to education and training for oral health, and (v) development of effective oral health management information systems. Many of the programmatic areas share similar characteristics described as a 'strategic orientation'. These strategic orientations give effect to the concepts of advocacy, equity, quality, partnership, operational research, communication and capacity building. The WHO Regional Committee for Africa (RC) is invited to review the proposed oral health strategy for the African region for the period 1999-2008 and provide an orientation for the improvement of oral health in member states in the region.     

Differences in the oral health status and oral hygiene practices according to the extent of post‐stroke sequelae

Oral health and hygiene are crucial parameters in stroke patients. However, few studies have evaluated the oral health status and oral hygiene practices according to the level of function in stroke patients. The aim of this study was to evaluate the oral health status and oral hygiene practices according to ambulation and personal hygiene levels in patients with stroke. Data from the fifth (2010‐2012) and sixth (2013‐2015) editions of the Korea National Health and Nutrition Examination Survey (KNHANES) for 6 years were combined. A total of 700 stroke patients were enrolled in our study. Subjective oral health was significantly poorer in patients who experienced a moderate problem with walking (adjusted OR [AOR], 1.68; 95% CI, 1.21‐2.33) and bed‐bound patients (AOR, 2.92; 95% CI, 1.01‐8.44) than in patients who could walk without difficulty. Patients who were unable to bathe or dress independently exhibited a significantly higher risk of dental caries than did those who could perform the same activities unassisted. The probability of brushing teeth ≥2 times daily was 69% lower in bed‐bound patients (AOR, 0.31; 95% CI, 0.11‐0.87) than in patients who could walk without difficulty and 76% lower in patients who were unable to bathe or dress independently (AOR, 0.24; 95% CI, 0.09‐0.62) than in those who could perform the same activities without difficulty. There were differences in oral health status and oral hygiene practices, according to ambulation level and functional independence, in the stroke patient group. These results indicate the need for oral care for stroke patients who exhibit ambulatory and functional limitations.     

A survey on oral health status and treatment needs of life-imprisoned inmates in central jails of Karnataka, India

Background: The prison population is a unique and challenging one with many health problems, including poor oral health. In a developing country like India, oral health problems of the prisoners had received scant attention. Objectives: To assess the oral health status and treatment needs of life imprisoned inmates and to know the existing oral health care facilities available in central jails of Karnataka. Materials and methodology design: Cross sectional survey Participants: A systematically selected sample of 800 life imprisoned inmates, were interviewed and examined using modified WHO oral health assessment proforma (1997). Results: The prevalence of caries was 97.5% mean Decayed Missing Filled Teeth(DMFT) was 5.26; Majority of the study population had Community Periodontal Index(CPI) score of 2, whereas 21.6% had at least one sextant with a CPI score of 4. 41.1% prisoners were severely affected with loss of attachment. 8.8% inmates had dentures. Oral sub mucous fibrosis was observed among 9.9% of prisoners. 97.4% of the subjects needed oral hygiene instruction, 87.6% needed restoration, 62.1% extraction of teeth and 32.2% needed prosthesis. Bangalore and Mysore central jail had oral health care facilities on regular basis. Conclusion: This study emphasises the need for special attention from government and voluntary organisations to improve the oral health of inmates.     

Dental Hygiene Intervention to Prevent Nosocomial Pneumonias

Nosocomial and ventilator associated pneumonias that plague critically ill, elderly and long-term care residents could be reduced with effective oral hygiene practices facilitated collaboratively between nurses and dental hygienists.BackgroundNosocomial pneumonias, specifically aspiration pneumonias and ventilator-associated pneumonias in the elderly and infirm have become a major health care issue, The provision of oral care in hospital and hospital-like facilities presents challenges that can prevent patients from receiving optimal oral care One sequela can be aspiration pneumonia which ranks first in mortality and second in morbidity among all nosocomial infections. Since aspiration pneumonia is linked to the colonization of oral bacteria in dental plaque and biofilm, it is time to look for creative solutions to integrating the expertise of dental hygienists into health care teams in these institutional settings.MethodsA comprehensive review of the literature was conducted regarding the etiology and prevalence of health care related pneumonias. Evidence describing the challenges and barriers that the nurses, nursing staff, and dental hygienists face in the provision of oral care in hospitals and long-term care facilities is provided. Intercollaborative solutions to providing optimal oral care in hospitals and long-term care facilities are suggested.ConclusionDental hygienists have the expertise and practice experience to provide oral care in hospitals, long-term care and residential facilities. They can contribute to solving oral care challenges through intercollaboration with other health care team members. Yet, there are long-standing systemic barriers that must be addressed in order to provide this optimal care. Dental hygienists becoming better assimilated within the total health care team in hospital and residential facilities can positively impact the suffering, morbidity and mortality associated with aspiration pneumonias.
