The Australian Government endorsed a national evidence based oral health model when it introduced the first Nursing Home Oral and Dental Health Plan in 2010. Called Better Oral Health in Residential Care, it promotes a multidisciplinary approach with doctors, nurses, care workers and dental professionals sharing responsibility for the four key processes of oral health screening, oral health care planning, daily oral hygiene and access to dental treatment. Frail and dependent residents are most conveniently treated on‐site, hence an aged care/dental partnership is encouraged to facilitate the use of portable dental equipment in the delivery of dental care.
Currently, few dentists provide services to residential aged care facilities (RACFs), with loss of clinical time in practice, difficulty in providing clinical care in a non‐dental environment and lack of referral pathways from the RACFs to the dentists contributing to the problem. The need to establish a model of care involving dental hygienists/oral health therapists in RACFs has merit.
Minimal intervention treatment using glass ionomer cement (GIC) and silver fluoride is ideal in aged care. However, GIC has limitation in dry mouths with low pH caused by polypharmacy or disease. Palliative and definitive treatment techniques need to be individualized with consideration of a patient's ability to maintain their own mouths as well as their mental and physical competence.
The range of products available to address the oral diseases common to the frail elderly is growing. The oral health care provider is required to establish a preventive regime that is tailored to the patient's needs, is realistic and under revision as the patient's needs change.
There is a lack of high quality evidence to support the effectiveness of oral health interventions and implementation strategies for older people with dementia or cognitive impairment. More rigorous, large scale research is needed in this area. Recommendations are provided to improve the overall quality of evaluation in this area. Emphasis must be placed on developing evidence-based, achievable and sustainable oral health strategies if the needs of people with dementia and cognitive impairment are to be met into the future.
An alternate technique of care to prevent, arrest and manage root caries using aqueous silver fluoride followed by stannous fluoride (AgF+SnF2) in aged care is demonstrated by three case studies. With increasing age, the inability to maintain ones own oral care from dementia, illness or frailty and polypharmacy induced salivary gland hypofunction will result in dental caries becoming a progessively greater burden for the elderly. Future generations of elders will live longer and need to maintain many more teeth longer than earlier generations. Both silver diamine fluoride (SDF)and AgF+SnF2 arrest and prevent caries and are easy to use in residential aged care facilities. Clinical differences between SDF and AgF+SnF2 are discussed. However, in aged care, AgF+SnF2 may offer advantages over SDF. AgF+SnF2 used to arrest and prevent caries in children can be modified to provide effective but minimally invasive care for an ageing and frail population. These techniques are rapid, inexpensive and nonthreatening suited to treat frail elders, dementia patients exhibiting challenging behaviours and patients with multiple rapidly progressing decay. Silver fluoride, applied before placing glass-ionomer cement (GIC) restorations is an important adjunct to the atraumatic restorative technique and may retard caries reactivation more than GIC used alone.
The role of nurses may have to be expanded beyond traditional roles to meet the growth and changes in oral health needs in residential facilities. Intensive training of a few lead advocate nurses to assess risk and formulate individualised NSCOCPs provides a method to transfer knowledge to untrained staff and deliver multicomponent preventive interventions soon after entry into residential care where timely visits by dental professionals to examine residents and prescribe preventive interventions are infrequent or unlikely.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
