The prevalence and experience of oral diseases in Adelaide nursing home residents

The document attached has been archived with permission from the Australian Dental Association. An external link to the publisher’s copy is included.Background: The twenty-first century will see the evolution of a population of dentate older Australians with dental needs very different from those of older adults in past years. This study provided comprehensive information concerning oral disease prevalence in older South Australian nursing home residents. Methods: This paper presents cross-sectional baseline results. Results: Most of the 224 residents, from seven randomly selected nursing homes, were functionally dependent, medically compromised, cognitively impaired and behaviourally difficult older adults who presented many complex challenges to carers and to dental professionals. Two-thirds (66 per cent) were edentulous with many dental problems and treatment needs. Dentate residents had a mean of 11.9 teeth present, higher than previously reported. The prevalence and experience of coronal and root caries and plaque accumulation was very high in dentate residents; especially males, those admitted more than three years previously, those who ate fewer food types and those who were severely cognitively impaired. These residents had more retained roots, decayed teeth and missing teeth, and fewer filled teeth when compared with data for community-dwelling older adults. Conclusions: This study highlighted the poor oral health status of these nursing home residents and the great impact of dementia on their high levels of oral diseases.JM Chalmers, C Hodge, JM Fuss, AJ Spencer, KD Carte

Opinions of dentists and directors of nursing concerning dental care provision for Adelaide nursing homes

The document attached has been archived with permission from the Australian Dental Association (7th Jan 2007). An external link to the publisher’s copy is included.Background: The complex oral health problems of nursing home residents have been well documented. However, the influences on residents’ oral health status, including opinions and experiences of dental professionals and nursing home staff, have not yet been adequately investigated. Methods: The baseline questionnaire component of this longitudinal study was mailed to all registered dentists practising in Adelaide and Adelaide nursing home directors of nursing (DONs). Results: 413 dentists and 97 DONs indicated that Adelaide dentists’ interest and training in nursing home dentistry was low. Dental service provision for nursing home residents was very low and dentists preferred to provide treatment at their dental practices. Few dental hygienists were working in nursing homes and dental professionals provided little educational assistance for nursing home staff. Dentists and DONs held several common and many varying perceptions of the problems associated with dental care provision in nursing homes. Both identified a group of nursing home environmental constraints and a lack of portable dental equipment. DONs further identified a group of resident related problems, and dentists a group of dental practicerelated problems. Conclusions: These study results provide important information concerning problems with nursing home dentistry for dental service providers, educators, policy-makers, administrators and nursing home staff.JM Chalmers, C Hodge, JM Fuss, AJ Spencer, KD Carter and R Mathe

Calf health from birth to weaning. III. housing and management of calf pneumonia

Calfhood diseases have a major impact on the economic viability of cattle operations. A three part review series has been developed focusing on calf health from birth to weaning. In this paper, the last of the three part series, we review disease prevention and management with particular reference to pneumonia, focusing primarily on the pre-weaned calf. Pneumonia in recently weaned suckler calves is also considered, where the key risk factors are related to the time of weaning. Weaning of the suckler calf is often combined with additional stressors including a change in nutrition, environmental change, transport and painful husbandry procedures (castration, dehorning). The reduction of the cumulative effects of these multiple stressors around the time of weaning together with vaccination programmes (preconditioning) can reduce subsequent morbidity and mortality in the feedlot. In most studies, calves housed individually and calves housed outdoors with shelter, are associated with decreased risk of disease. Even though it poses greater management challenges, successful group housing of calves is possible. Special emphasis should be given to equal age groups and to keeping groups stable once they are formed. The management of pneumonia in calves is reliant on a sound understanding of aetiology, relevant risk factors, and of effective approaches to diagnosis and treatment. Early signs of pneumonia include increased respiratory rate and fever, followed by depression. The single most important factor determining the success of therapy in calves with pneumonia is early onset of treatment, and subsequent adequate duration of treatment. The efficacy and economical viability of vaccination against respiratory disease in calves remains unclear

The oral health of Adelaide nursing home residents: longitudinal study

The definitive version is available at www.blackwell-synergy.comObjective: The Adelaide Dental Study of Nursing Homes aimed to quantify oral disease experience, incidence and increments in Adelaide nursing home residents. Methods: Questionnaires and dental inspections were completed at baseline and at 1-year for residents from randomly selected Adelaide nursing homes. Results: The residents were very functionally dependent, cognitively impaired and behaviourally difficult older adults with complex oral problems and dental treatment needs. The prevalence of edentulism (total tooth loss) (63%) decreased and more residents were retaining natural teeth. Existing residents had a mean of 10.8 teeth present and new residents had a mean of 12.7 teeth present. Residents’ previous experiences of caries (decay) were high – existing residents had a mean of 1.2 decayed teeth and new residents had a mean of 0.8 decayed teeth. Residents’ caries increments (new decay) over the 1-year period were high (coronal = 2.5 surfaces; root = 1.0 surfaces), especially in those who had lost weight and who could eat fewer food types. These levels of caries were many times greater than had been reported for communitydwelling older adults. Large accumulations of plaque, calculus and debris (food) were evident on residents’ natural teeth and dentures, especially those with dementia. Up to 25% of residents owned dentures that were not worn. Residents with dementia gave their carers complex and challenging oral hygiene care problems. Existing and new residents had similar general health and oral health characteristics, with the exceptions that new residents had significantly more filled tooth surfaces, and fewer decayed retained roots. Conclusion: New residents were being admitted to the nursing homes with a compromised oral health status or developed severe oral diseases and conditions within several months of their admittance. Residents’ oral diseases, especially coronal and root caries, rapidly progressed during their stay in residential care.JM Chalmers, KD Carter and AJ Spence
