ABSTRACT

Objectives: Older adults with a neurological disorder often have difficulty maintaining oral hygiene due to functional limitations that increase the risk of oral and systemic complications. The applicability of an integrated oral care intervention using a multichannel oral irrigator (MCOI) in home-dwelling older adults was explored. Methods: This case study included older adults with neurological disorders. The intervention consisted of professional oral hygiene care, oral motor training, and MCOI use over five weeks. Oral health was assessed using the Simplified oral hygiene index (S-OHI), Community Periodontal index of treatment needs (CPITN), Winkel tongue coating index (WTC), and turbidity at baseline, three weeks, and five weeks. Results: There were improvements in the S-OHI and WTC, indicating better plaque control and reduced tongue coating. Changes in the CPITN were limited, which is likely to be due to the short intervention period. Turbidity findings indicate effective removal of oral debris. Conclusions: Integrated interventions, including the MCOI, may be considered to be a feasible supportive approach for oral hygiene management in older adults with neurological disorders, while continuous care and caregiver involvement remain important.
