Advanced restorative dentistry - a problem for the elderly? An ethical dilemma

Australian dental school academics' perceptions of gerodontology education in the undergraduate curriculum

INTRODUCTION

Australia's rapidly growing population of dentate, frail, care-dependent older people require graduates skilled in managing the health needs of this patient group. The perceptions of academics teaching gerodontology may inform future dental curricula recommendations. This study explored the perceptions of gerodontology education amongst Australian dental school academics.

MATERIALS AND METHODS

All nine Australian dental schools providing entry-to-practice dentistry programs were invited to participate in semi-structured interviews. Academics from six dentistry programs took part, and the data were analysed using a thematic approach.

RESULTS

The three main themes identified from interviews included 'clinical exposure', 'organisational levers', and 'sociological barriers'. The attitudes of students, as well as society and health professionals, were seen as strongly influential in preparing the workforce for managing the oral health of older people. The themes inter-linked with a knock-on effect where societal attitudes and organisational levers impact on the ability to successfully support students' preparation for gerodontology practice. Limited resources were barriers to achieving ideal learning and teaching and continued upon graduation as oral health care for older people was perceived as undervalued and under-resourced.

CONCLUSION

There has been a continued cycle of failure in healthcare schemes and advocacy for the improvement of oral health for older people which has contributed to the inadequate preparation of dental graduates for managing frail and care-dependent older people. Organisational, societal, and political change is needed to support the education of dental students in this area to ensure graduate dentists are competent to manage the oral care needs of this growing population.

Prevention of oral diseases for the older person (Part 1)

Older adults often experience poorer levels of oral health than younger adults, especially if they have become dependent on a third party to support their daily oral care routine. However, the deterioration of oral health does not need to be a part of the ageing process. Most oral diseases are largely preventable with the daily removal of dental plaque that forms on teeth and dentures, using a fluoride toothpaste, eating a healthy diet and reducing any tobacco consumption. The dental team have a duty of care to ensure that older people receive evidence-based oral health preventative advice tailored to the individual, taking into account individual risk factors that can increase with age. This can include the clinical application of topical fluoride and minimally invasive dentistry. Older people at an increased risk of poor oral health include those with cognitive conditions, physical impairments and certain medical conditions. Care home residents face particular barriers to attaining a satisfactory standard of oral care which are discussed herein. Good oral health preventative routines must be established early after the diagnosis of progressive chronic conditions and will help to prevent the need for dental intervention later in life when treatment can be more difficult to tolerate. Inclusion of oral health prevention within health policy and legislation is necessary to improve the oral health for older people living in all health and care settings.

Educating dental students to provide compassionate age friendly care for older adults

As the world population ages, the need for age friendly care increases. In dentistry, age friendly care requires an appropriate comprehension of multiple factors that can be categorized in socio-economic circumstances, systemic health problems, and oral health conditions. In addition to the understanding of these factors and its relationships among each other, the future dental workforce should also be aware of unconscious and pervasive societal stereotypical perception of older persons, aging, and being old, which results in ageism and ageist attitudes. Dental schools can play an important role on raising ageism awareness and combating ageism in healthcare, thus preparing the future of the dental workforce to provide compassionate age friendly care. This paper will discuss ageism in dental schools and learning strategies used to combat it and increase compassionate care delivery for older adults.

Dental informed consent challenges and considerations for cognitively impaired patients

Because the US population is living to an older age, the number of individuals with cognitive impairment and periodontitis is increasing, as both conditions/diseases increase with age. Dental informed consent best practices for dental/periodontal treatment of individuals with cognitive impairment have not been explored, yet warrant consideration, because complex dental treatments to address periodontal needs/edentulism raise challenges for informed consent in the elderly with cognitive impairment. The purpose of this review is to help practitioners better understand this topic and develop best practices in dentistry for informed consent of patients with cognitive impairment that need extensive dental treatment, including surgical and implant therapy.

The impacts of oral health-related quality of life of elderly people living at home: a cross-sectional study

The scope was to verify the impact of oral and sociodemographic conditions, the dental treatment needs and dental pain, on the quality of life of the elderly. This cross-sectional study was conducted in 15 primary health care areas. A backward multivariate linear regression model was used (p<0.05) with oral health related-quality of life as dependent variable. There were 335 elderly people with predominance of women (56.72%) and aged up to 74 years (59.40%). Those who had up to 8 years of education predominated (87.46%), and those who were still working were the minority (13.43%). Multivariate linear regression (p<0.05) showed association with missing teeth (β=0,12; IC 0,00:0,04; p<0,04) and dental prosthesis needs (β=0,14; IC 0,13:0,81; p<0,01), women (β=0,18; IC 0,23:0,85; p<0,01), less aged (β=-0,12; IC -0,05:0,00; p<0,02), not working (β=-0,15; IC -1,09:-0,20; p<0,01), with dental care need (β=0,24; IC 0,25:0,63; p<0,01) and dental pain (β=0,14; IC 0,10:0,64; p<0,01). Missing teeth, sociodemographic conditions, dental treatment needs and dental pain might impact oral health-related quality of life of elders.

How effective and cost-effective is water fluoridation for adults? Protocol for a 10-year retrospective cohort study

BACKGROUND

Tooth decay can cause pain, sleepless nights and loss of productive workdays. Fluoridation of drinking water was identified in the 1940s as a cost-effective method of prevention. In the mid-1970s, fluoride toothpastes became widely available. Since then, in high-income countries the prevalence of tooth decay in children has reduced whilst natural tooth retention in older age groups has increased. Most water fluoridation research was carried out before these dramatic changes in fluoride availability and oral health. Furthermore, there is a paucity of evidence in adults. The aim of this study is to assess the clinical and cost-effectiveness of water fluoridation in preventing invasive dental treatment in adults and adolescents aged over 12.

METHODS/DESIGN

Retrospective cohort study using 10 years of routinely available dental treatment data. Individuals exposed to water fluoridation will be identified by sampled water fluoride concentration linked to place of residence. Outcomes will be based on the number of invasive dental treatments received per participant (fillings, extractions, root canal treatments). A generalised linear model with clustering by local authority area will be used for analysis. The model will include area level propensity scores and individual-level covariates. The economic evaluation will focus on (1) cost-effectiveness as assessed by the water fluoridation mean cost per invasive treatment avoided and (2) a return on investment from the public sector perspective, capturing the change in cost of dental service utilisation resulting from investment in water fluoridation.

DISCUSSIONS

There is a well-recognised need for contemporary evidence regarding the effectiveness and cost-effectiveness of water fluoridation, particularly for adults. The absence of such evidence for all age groups may lead to an underestimation of the potential benefits of a population-wide, rather than targeted, fluoride delivery programme. This study will utilise a pragmatic design to address the information needs of policy makers in a timely manner.

Assessment of root caries under wet and dry conditions using swept-source optical coherence tomography (SS-OCT)

The purpose of this study was to compare optical properties of root caries under two observing conditions using swept-source optical coherence tomography (SS-OCT). In vitro and natural root caries were observed by SS-OCT under wet and dry conditions, followed by confocal laser scanning microscope (CLSM) and transverse microradiography (TMR). Signal intensity (SI), distance between SI peaks (SI-distance) and optical lesion depth were obtained from OCT. Lesion depth was measured from CLSM; lesion depth (LD_TMR) and mineral loss (ML) were obtained from TMR. In vitro root caries under wet and dry conditions showed different OCT images and SI patterns. Lesion depth of OCT and that of CLSM, SI-distance and LD_TMR, LD_TMR and ML significantly correlated. Under dry conditions, half natural root caries showed similar OCT images and SI patterns as in vitro root caries. The base of demineralized dentin could be detected more clearly under dry conditions than under wet conditions.
