The Effect of Regular Home Use of Dual-light Antibacterial Photodynamic Therapy (aPDT) or the Use of a Powered Toothbrush in Older Individuals With Periodontitis and Mild Cognitive Impairment.

"Intervention Group B:~Participants receive standardized oral hygiene instructions and use an Oral-B iO powered toothbrush during the test period.~The Oral-B iO is an advanced powered toothbrush that combines oscillating-rotating and micro-vibrating bristle movements with real-time feedback technology. It is CE-marked for home use and designed to improve plaque removal and overall oral hygiene compared to manual toothbrushing. The device incorporates pressure sensors and guided brushing modes to support optimal brushing technique and patient adherence, which may contribute to improved periodontal outcomes."

"Intervention Group A:~Participants receive standardized oral hygiene instructions and use only a manual toothbrush during the test period, with the addition of an adjunctive antimicrobial photodynamic therapy (aPDT) device (Lumoral®).~The Lumoral® treatment device is a CE-marked antibacterial device intended for home use. It is designed to support the treatment and prevention of oral diseases caused by bacterial biofilms. The device functions by emitting light at a specific wavelength, which activates a CE-marked photosensitizing mouthrinse, Lumorinse®. This light-activated process enhances antibacterial efficacy, targeting pathogenic microorganisms in the oral cavity and supporting improved oral hygiene outcomes."
