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.
Sponsor: Blekinge Institute of Technology
Summary
Objective: To compare three different oral hygiene regimens regarding plaque index (PI), bleeding on probing (BOP), the number of deepened periodontal pockets ≥4 mm (PPD), oral halitosis, and changes in oral health-related quality of life (OHRQoL) in an older population with periodontitis stage I-III and mild cognitive impairment. 1. Are there improvements in plaque index (PI), number of bleeding on probing (BOP) sites, number of probing depths (PPD), and intraoral halitosis in the two test groups compared to the control group? 2. Do the study interventions affect oral health-related quality of life in older adults with periodontitis and mild cognitive impairment? Study design: Type: Randomized controlled trial Duration: 6 months per participant, 2 years in total for data collection Participants: 90 participants divided into Intervention and Control groups Intervention Group A (Lumoral Dual-Light aPDT + Manual Toothbrush) Standardized oral hygiene instructions and the use of a manual toothbrush during the test period, with an adjunctive aPDT device (Lumoral®). Intervention Group B (Oral-B iO Powered Toothbrush) Standardized oral hygiene instructions and the use of an Oral-B iO powered toothbrush during the test period. Control Group Standardized oral hygiene instructions and the use of a manual TePe Select extra soft toothbrush during the test period.

Interventions
Oral-B Powered toothbrush
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.
Dual-Light aPDT Treatment - Lumoral
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.
