The impact of aromatherapy-based oral care on oral conditions, salivary pH, and halitosis in older adults with dementia: Pilot study

Inadequate oral care and poor oral health in older adults are known to increase the risk of dementia. Dementia patients residing in long-term care facilities are especially vulnerable to oral diseases due to their care-resistant behavior. This study aimed to investigate the effects of a 7-day oral care program based on an aroma solution in 58 dementia patients (29 each in the experimental and control groups) admitted to a long-term care hospital in South Korea. The experimental group received oral care with a solution containing peppermint, tea tree, and lemon essential oils, and the control group with a saline solution. The effectiveness of oral care was assessed by the participants’ oral condition, salivary pH, and halitosis. The experimental group showed significant improvements (P<.001) in all three outcomes, indicating that oral care with an aroma solution can improve the oral health of older dementia patients residing in long-term care facilities.
