Risk factors for aspiration pneumonia in frail older people: a systematic literature review

OBJECTIVE To systematically review the risks for aspiration pneumonia in frail older people and the contribution of bad oral health among the risk factors. DESIGN Systematic literature review. SETTING PubMed (Medline), Web of Science, Cochrane Library, EMBASE, and CINAHL were searched for eligible studies, published in English in the period January 2000 to April 2009. PARTICIPANTS Frail older people. MEASUREMENTS Only publications with regard to hospitalized, institutionalized, or frail home-dwelling people of 60 years and older were eligible. Two authors independently assessed the publications for their methodological quality. Unadjusted and adjusted odds ratios and their corresponding 95% confidence intervals for respective risk factors related to aspiration pneumonia were extracted. The results were evaluated according to the levels of evidence of the Oxford Centre for Evidence-based Medicine. RESULTS A total of 21 publications fulfilled the quality criteria. Evidence level 2a (systematic review with homogeneity of cohort studies) was found for a positive relationship between aspiration pneumonia and age, male gender, lung diseases, dysphagia, and diabetes mellitus; 2b (individual cohort study) for severe dementia, angiotensin I-converting enzyme deletion/deletion genotype, and bad oral health; 3a (systematic review with homogeneity of case-control studies) for malnutrition; 3b (individual case-control study) for Parkinsons disease and the use of antipsychotic drugs, proton pump inhibitors, and angiotensin-converting enzyme inhibitors. The contribution of bad oral health among the risk factors seems limited. CONCLUSION Thirteen significant risk factors were identified: age, male gender, lung diseases, dysphagia, diabetes mellitus, severe dementia, angiotensin I-converting enzyme deletion/deletion genotype, bad oral health, malnutrition, Parkinsons disease, and the use of antipsychotic drugs, proton pump inhibitors, and angiotensin-converting enzyme inhibitors. The contribution of bad oral health seems limited.

Efficacy of ultrasonic versus laser-activated irrigation to remove artificially placed dentin debris plugs.

INTRODUCTION The study assessed the efficacy of laser activated irrigation (LAI) with Erbium: Yttrium Aluminum Garnet (Er:YAG) and Erbium Chromium: Yttrium Scandium Gallium Garnet (Er,Cr:YSGG) wavelengths as compared with passive ultrasonic irrigation (PUI). Previously proposed irrigation times were used for LAI (4x 5 seconds) and the intermittent flush technique (3x 20 seconds). METHODS We used a split root model with an artificial root canal wall groove. Roots were prepared to an apical size # 40 with ProFiles 0.06 (Dentsply Maillefer, Baillaigues, Switzerland). Five groups of 20 straight canine roots were evaluated as follows: Group 1: hand irrigation for 20 s with 2.5% NaOCl (CI); Group 2: PUI performed once for 20 s with the #20 Irrisafe (Satelec Acteon group, Merignac, France) (PUI 1); Group 3: PUI for 3x 20 s with the Irrisafe (PUI 2); Group 4: LAI with the Er,Cr:YSGG laser and Z2 (200 microm) Endolase tip (Biolase, San Clemente, USA) at 75 mJ for 4x 5 s (LAI 1); Group 5: LAI with the Er:YAG laser (HoYa Versawave, Cortaboeuf, France) and a 200 mum endodontic fiber at 75 mJ for 4x 5 s (LAI 2). Images from the groove were taken before and after irrigation. The quantity of dentin debris in the groove after the experimental protocols was evaluated. RESULTS Statistically significant differences (p < 0.05) were found between CI and all other groups and between PUI 1 and the other groups. CONCLUSION LAI techniques using erbium lasers (Er:YAG or Er,Cr:YSGG) for 20 seconds (4x 5 seconds) are as efficient as PUI with the intermittent flush technique (3x 20 seconds).

The independent impact of household- and neighborhood-based social determinants on early childhood caries - A cross-sectional study of inner-city children

This study examined the relationship between early childhood caries (ECC) and measures of socioeconomic status as environmental determinants of oral health inequalities. Dental caries and quality of oral hygiene were reported on 384 young inner-city children (24–35 months) by clinical examination. Early childhood caries was diagnosed in 18.5% of children. Ethnicity (P < 0.001) and neighborhood (P < 0.001) were the social variables significantly predictive of ECC in a logistic regression model. Living in a deprived neighborhood and the mother being of East European descent were the social variables with strongest association with ECC. These variables can be considered adequate criteria to identify groups at risk within the overall population.

European College of Gerodontology: undergraduate curriculum guidelines in Gerodontology

Effective undergraduate teaching of gerodontology to present and future dental students is important if good oral health care of older people is to be assured. A review of the undergraduate curriculum for gerodontology is presented and indicates the need for a knowledge base from which new graduates can develop a special interest in care of older patients. The aim is improved care of older patients, satisfaction for teaching staff involved and improved professional standing for Dentistry. Motivation of students could also be achieved by the positive match between rising patient awareness and ethical responsibility of the profession for those older patients. As it stands, the undergraduate curriculum should include topics on specific care for the elderly and other patient groups, which extend the competences already agreed by the Association for Dental Education in Europe (ADEE). The logistics of teaching these topics will need co-ordination of those staff with appropriate skill and interest, preferably as a development of existing curriculum content.

Association of some specific nutrient deficiencies with periodontal disease in elderly people: A systematic literature review.

OBJECTIVE Deficiency of vitamin B complex, vitamin C, vitamin D, calcium, and magnesium has been associated with periodontal disease. This article systematically reviews the currently available literature on the feasible association of vitamin B complex, vitamin C, vitamin D, calcium, and magnesium deficiencies with periodontal disease in elderly people. METHODS We performed a systematic review of relevant English- and Dutch-language medical literature published from January 1990 to May 2007, with critical appraisal of those studies evaluating the association of vitamin B complex, vitamin C, vitamin D, calcium, and magnesium deficiencies with periodontal disease in elderly people. RESULTS None of the studies meeting the selection criteria included institutionalized elderly people. In the studies on non-institutionalized elderly people, no significant or consistent association was found between vitamin B complex, vitamin C, vitamin D, calcium, and magnesium dietary intakes and serum levels and periodontal disease. Although in those studies decreased dietary vitamin C intake was found to be associated with increased risk of periodontal disease, no conclusive evidence could be demonstrated. CONCLUSION There is no evidence of an association of vitamin B complex, vitamin C, vitamin D, calcium, and magnesium deficiencies with periodontal disease in non-institutionalized elderly people. To produce conclusive evidence on the subject of this systematic literature review, longitudinal cohort studies and follow-up randomized controlled trials are needed.

An oral health care guideline for institutionalised older people.

Institutionalized older people are prone to oral health problems and their negative impact due to frailty, disabilities, multi-morbidity, and multiple medication use. Until recently, no evidence-based oral health care guideline for institutionalized older people has been available. For that reason, the Dutch Association of Nursing Home Physicians developed the Oral health care Guideline for Older people in Long-term care Institutions (OGOLI), meeting the requirements of the AGREE instrument for assessing a guidelines quality. This short report presents the keynotes and the content of the Oral health care Guideline. Most recommendations are based on expert opinions. Only 4 recommendations (education, pneumonia, use of an electric toothbrush, and fluoride rinsing in case of a sudden increase of oral plaque amount) are based on evidence level A2 conclusions. This emphasizes the need for further research on oral health of institutionalized older people.

Sociodemographic Determinants for Oral Health Risk Profiles

The present study aimed to explore the association between caries risk profiles and different sociodemographic factors . The study sample (n = 104) was randomly selected within an urban population in Flanders, Belgium. Caries risk was assessed by anamnesis, clinical examination, salivary tests, and a questionnaire. Age, gender, and socio-economic status were extracted from social insurance data files. Social indicators were “occupational status,” “being entitled to the increased allowance for health care interventions” and having access to the “Maximum Bill” (MAF), initiatives undertaken to protect deprived families. In the bivariate analysis there were significant differences in risk profiles between occupational groups (P < .001), between entitled and non-entitled individuals to the increased allowance (P = .02), and between access or no-access to the MAF (P < .01). The multiple logistic model showed a significantly higher chance of being in the low risk group for individuals with no-access to the MAF compared to those with access (OR:14.33–95% C.I. 2.14–95.84).

Higher education in Gerodontology in European Universities

BackgroundThe rapid aging of the European population and the subsequent increase in the oral care needs in older adults necessitates adequate training of dental professionals in Gerodontology (Geriatric Dentistry). This study was designed to investigate the current status of Gerodontology teaching amongst European dental schools at the undergraduate, postgraduate and continuing education levels.MethodsAn electronic questionnaire was developed by a panel of experts and emailed to the Deans or other contact persons of 216 dental schools across 39 European countries. The questionnaire recorded activity levels, contents and methodology of Gerodontology teaching as part of dental education programs. Repeated e-mail reminders and telephone calls were used to encourage non-responders to complete the questionnaire.ResultsA total of 123 responses from 29 countries were received (response rate: 56.9%). Gerodontology was taught in 86.2% of schools at the undergraduate level, in 30.9% at the postgraduate level and in 30.1% at the continuing education level. A total of 43.9% of the responding schools had a dedicated Gerodontology program director. Gerodontology was taught as an independent subject in 37.4% of the respondent schools. Medical problems in old age, salivary impairment and prosthodontic management were the most commonly covered topics in Gerodontology teaching. Clinical teaching took place in 64.2% of the respondent schools, with 26.8% offering clinical training in outreach facilities.ConclusionsThe vast majority of European dental schools currently teach Gerodontology at the undergraduate level. More training opportunities in oral care of frail elders should be offered, and more emphasis should be placed on interdisciplinary and interprofessional training, educational collaborations, and the use of modern technologies. Dedicated postgraduate Gerodontology courses need to be developed to create a significant number of specialized dentists and trained academics.

An Expert Opinion from the European College of Gerodontology and the European Geriatric Medicine Society: European Policy Recommendations on Oral Health in Older Adults

This is an expert opinion paper on oral health policy recommendations for older adults in Europe, with particular focus on frail and care‐dependent persons, that the European College of Gerodontology (ECG) and the European Geriatric Medicine Society (EUGMS) Task and Finish Group on Gerodontology has developed. Oral health in older adults is often poor. Common oral diseases such as caries, periodontal disease, denture‐related conditions, hyposalivation, and oral pre‐ and cancerous conditions may lead to tooth loss, pain, local and systemic infection, impaired oral function, and poor quality of life. Although the majority of oral diseases can be prevented or treated, oral problems in older adults remain prevalent and largely underdiagnosed, because frail persons often do not receive routine dental care, due to a number of barriers and misconceptions. These hindrances include person‐related issues, lack of professional support, and lack of effective oral health policies. Three major areas for action are identified: education for healthcare providers, health policy action plans, and citizen empowerment and involvement. A list of defined competencies in geriatric oral health for non‐dental healthcare providers is suggested, as well as an oral health promotion and disease prevention protocol for residents in institutional settings. Oral health assessment should be incorporated into general health assessments, oral health care should be integrated into public healthcare coverage, and access to dental care should be ensured.

Opinions of dentists on the barriers in providing oral health care to community-dwelling frail older people: a questionnaire survey

OBJECTIVE The aim of this study was to investigate to what extent dentists in the Netherlands experience barriers in providing oral health care to community-dwelling older people. BACKGROUND As most publications on the barriers in providing oral health care to older people consist of surveys on oral health care in care homes, it was decided to investigate the barriers dentists experience in their own dental practices while providing oral health care to community-dwelling frail older people. MATERIAL AND METHODS A representative sample of 1592 of the approximately 8000 dentists in the Netherlands aged 64 or younger were invited to respond to a questionnaire online. The dentists were asked to respond to 15 opinions concerning oral healthcare provision to community-dwelling frail older people aged 75 years or more who experience problems in physical, psychological and social areas, as well as possible financial problems. RESULTS The total response rate was 37% (n = 595; male=76%; average age 49). The majority of those who responded agreed that the reimbursement of oral health care to older people is poor. Two thirds of those who responded (66%) agreed that there are limited opportunities to refer the frail and elderly with complex oral healthcare problems to a colleague with specific knowledge and skills. CONCLUSION Dentists experienced barriers in two domains; a lack of knowledge and practical circumstances. It was concluded that the dentists gender, age, year of graduation and the number of patients aged 75 years or more treated weekly were in some respect, related to the barriers encountered.
