The effect of oral massage intervention on oral hygiene at home care

<jats:title>Abstract</jats:title><jats:sec><jats:title>Introduction</jats:title><jats:p>Oral hygiene for individuals with disabilities living at home heavily relies on caregiver assistance. This study investigates differences in mouth opening, dental plaque index and halitosis grade among home‐dwelling individuals with and without oral massage intervention. It is important to consider that extended bedridden periods, the presence of nasogastric tubes and difficulties in mouth opening can affect caregivers' oral cleaning effectiveness.</jats:p></jats:sec><jats:sec><jats:title>Method</jats:title><jats:p>This single‐blind controlled experiment spanned 12 weeks. Primary caregivers underwent a 15‐ to 20‐min demonstration. The experimental group received guidance on the Bass brushing method, instructions for using oral cleaning tools and training in oral massage. The control group received guidance on the Bass brushing method and instructions for oral cleaning tools. Measurement tools included basic participant information, oral examination records, mouth opening assessments, dental plaque index evaluations and halitosis ratings.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>The study included 38 subjects, all over 80 years old with disabilities. Dental plaque index significantly improved after massage (<jats:italic>p</jats:italic> = 0.001). Compared to their pre‐massage conditions, the experimental group showed significant improvements in maximum mouth opening (11.65–20.71 mm, <jats:italic>p</jats:italic> = 0.001), dental plaque index (98.04%–59.74%, <jats:italic>p</jats:italic> < 0.0001) and halitosis rating (4.12–3.76, <jats:italic>p</jats:italic> = 0.034).</jats:p></jats:sec><jats:sec><jats:title>Conclusions</jats:title><jats:p>Oral massage effectively improved mouth opening, reduced the dental plaque index and lowered halitosis ratings in the experimental group, underscoring its positive impact on oral hygiene. The study's insights can significantly benefit oral care for individuals with disabilities living at home.</jats:p></jats:sec>
