Special Care Dentistry –a reality

This issue coincides with celebrations for the United Nations International Day of Disabled Persons on Friday 3rd December 2006. Under a banner fittingly entitled ‘enable’ the day seeks to ensure full and equal enjoyment of human rights, and participation in society, by persons with disabilities.

Earlier this year, in August 2006 the Biennial Congress of the International Association for Disability and Oral Health took place in Göteborg, Sweden. Delegates to the Congress had the opportunity to do just that: to play their part in planning a better future for the oral health of people with disabilities, when oral health care teams from over 40 nations came together to share science, good practice and to support and mentor colleagues in the role of providing oral health care for some of the most vulnerable and sometimes, the most challenging members of society. Our second issue of the year –was devoted to publication of the abstracts from the Congress.

For so long a ‘gold standard’ in the way that they have delivered care, the showcasing of the Nordic countries at the conference gave others the opportunity to see the way in which such centres provided oral and dental care in a  truly holistic way, as well as novel approaches to education and training. As with the IADH Congress in Calgary in 2004, there was another ambitious programme of funding to bring delegates from less developed countries to the Congress – to learn from them as well as give them a voice in seeking support for disabled people in countries where even basic oral health care is not a feature.

Increasingly throughout the world – both developed and developing, there is the realisation that this often disparate group of so called ‘special needs’ patients is only going to get larger and we need to invest in the resources now to ensure that all their health care needs are provided. Alongside other specialties we know that we need to work harder to develop the evidence base for what we do, based as it is currently on good practice honed from years of experience.

One has only to read the many abstracts, at this and other conferences to know that there is so much work being done out there, often in isolation from peers, who would help to make the task that much easier; there may be duplication of effort too, so limited are the networks for some people. I would urge you however to make others aware of what you are doing – if nothing else, to prevent researchers from ‘re-inventing the wheel’ and let the wider dental community see that there is much sound and scientifically robust about Special Care Dentistry.

Another very heartening aspect of the IADH Congress in Göteborg was the many young people present at the Congress; for some people working in other branches of dentistry there is a real anxiety that we have not built in succession – there are no young, keen clinicians, researchers, academics, prepared to take on the role now occupied by the leaders in our specialty. This is not so for Special Care Dentistry; a vibrant, outward looking body of people with a people-centred approach to what they do. But, they need their seniors to leave a legacy of a sound training framework and a career with prospects, if patients too are not to lose out.

There is much to be optimistic about as we approach 2007!

Defining the population requiring special care dentistry using the International Classification of Functioning, Disability and Health – a personal view.

Abstract

Aims and objectives: The aim of this article is to propose a classification of the population in need of special care in dentistry in relation to the International Classification of Functioning, Disability and Health (ICF), and to extrapolate a definition of the population concerned. A definition of the population requiring special care dentistry is essential in order to gather epidemiological data to describe current health status and to project the economic, medical and social consequences of disability and disease. It is also necessary for the attribution of dental health resources and the planning of services.
Design: The ICF is a World Health Organisation (WHO) document that may provide the framework for a definition of the population requiring special care. This classification was analysed for items relating directly or indirectly to oral health.
Results: Three groups of items were identified: i) items relating directly to the oral sphere, ii) items having an influence on oral function and health and iii) environmental factors affecting oral status.
Conclusion: A definition based on the second group of ICF items was proposed: persons requiring special care dentistry are those with a disability or activity restriction that directly or indirectly affects their oral health, within the personal and environmental context of the individual.

Abstract

Aim: Exposure to antineoplastic drugs poses risk to health providers who may be treating children undergoing cancer or immune therapy.
Objective: This study compares methotrexate (MTX) concentrations in saliva and plasma against a concentration standard for lymphocyte mutagenicity (0.100 µmol/L).
Design: Five osteosarcoma patients expectorated 5mL of unstimulated saliva into a sterile collection tube at 24, 48 and 72 hours post-MTX administration, paralleling blood sampling, and yielding 33 samples. Saliva was analysed using fluorescence polarization immunoassay (FPIA) to determine MTX concentrations; creatinine and blood urea nitrogen (BUN) also were measured using standard techniques.
Results: Mean saliva MTX at 24 hours (0.138µmol/L) exceeded in vitro mutagenic standard, but did not at 48h and 72h post infusion.

Abstract

This paper examines the use of hypnosis in general dentistry specifically in a sedation context, briefly looking at the history of hypnosis and our current understanding of it, before going on to describe its use as alternative and adjunct to conscious sedation. Hypnosis is an important and effective adjunct to sedation and this paper aims to give an overview of this relationship. However, there is limited qualitative and quantitative research in the literature examining the relationship between hypnosis and sedation, which makes in-depth discussion difficult. There is therefore a need for good experimental evidence. There will only be sufficient clinical data to move hypnosis from just an experimental interest, and to turn it into a viable treatment option for the mainstream holistic treatment of patients, if clinicians are willing to undertake objective research with this modality. The effects of hypnotic suggestion- motivation, removal of fear and doubt, fixation of attention, relaxation and limited voluntary movements, monotony, and suppression of other ideas, are all useful for patient management. Since these effects come from communication skills which are fundamental to dentistry, it has been suggested that knowledge of hypnotic techniques and principles is important for general patient management by all clinicians, whether or not they wish to use ‘formal’ hypnosis.

Guidelines for the delivery of a Domiciliary Oral Health Care Service
All Wales Special Interest Group – Special Oral Health Care

Abstract

This document forms the basis for developing guidelines in the provision of domiciliary oral health care as part of a special care dental service. Its purpose is to state clearly the aims and objectives of a putative domiciliary oral health care service; to define the criteria by which clients referred to such a service may be assessed, and to formulise as guidelines, the procedures which might be undertaken by such a service.

Abstract

Aim: To investigate the levels of oral disease in adults with disability, requiring treatment under general anaesthesia at Cork University Hospital.
Objective:Prior to treatment, caries experience and previous treatment, debris, gingival and CPITN readings were measured for 66 consecutive adult patients requiring treatment at the above clinic.
Results:The patients aged 16 to 52 years had a mean dental caries experience of 12.9 and the proportion of untreated decay in the study sample was 31%, the extracted component was 42% and the previously restored component was 27%. Sixty one per cent had debris present on all six examined tooth surfaces. Forty seven per cent had gingival bleeding at all six examined sites and 74% of patients had periodontal pocketing present.
Conclusions: : Prior to treatment the patients in the study had a low proportion of teeth restored and high proportions of untreated decay and extractions. There was a high prevalence of debris and periodontal disease.

Abstract

Background:A review was conducted of a dental programme for people with disabilities located in an acute care hospital, to assess if there was a need for such a programme, based on the demand and profile of the patients and to examine the mortality data for those registered patients that have died.
Material and Methods:A retrospective review was undertaken of the database that included all patients registered with the dental programme for people with disabilities.
Results:The review revealed that there were 2,701 registered patients and that this represented a doubling of the patient population since the last review in 1996. There was an increase in the number of patients with multiple co-morbidities and the utilisation of general anaesthesia to provide their required dental care rose from 48% to 56%. Finally, analysis of the 102 individuals who died revealed that the mean age of death was 39 years, which was considerably lower than that reported in the literature for people with disabilities or the general population. The most common cause of death was related to respiratory illness.
Conclusions:These findings would support the conclusion that there is a significant need for a dental programme for persons with disabilities in the community, and that the programme must be able to provide care under general anaesthesia. The hospital programme will see individuals with multiple co-morbidities. Finally, it is possible that a link between oral health and related bacterial flora and respiratory disease and death may exist in this population which warrants future investigation.

Abstract

Aim:To evaluate the flow rate, pH and buffer capacity in saliva of adolescents with cerebral palsy (CP).
Method: Twenty-four adolescents with CP (14 boys) attending Lar Escola Sao Francisco Rehabilitation Center (age mean±S.D.=12±2) were compared with eighteen adolescents (10 boys) without CP (age mean±S.D.=12±4). The whole saliva was collected under slight suction. Flow rate was calculated in ml/min, and the pH and the buffer capacity were determined using a digital pH meter. The buffer capacity was measured by titration with 0.01 N HCl.
Results: Were statistically analysed by Student’s t test. Salivary flow rate, pH and buffer capacity in the pH interval of 6.9-6.0 were significantly lower in individuals with CP (P<0.0001; 0.0063; and 0.0014 respectively). Boys and girls from the cerebral palsy group demonstrated a significantly lower flow rate and buffer capacity in the pH range of 6.9-6.0 than the boys and girls from the control group (P= 0.016; 0.0362; <0.0001; and 0.0003 respectively). The salivary pH was significantly lower in boys with CP (P= 0.0022) while the girls from the same group showed no difference when compared with control group (P=0.195).
Conclusions: That adolescents with CP present lower pH, flow rates and buffer capacity in comparison to the control group, which increases the risk of oral diseases in this population.
