Home Use of Dual-light Photodynamic Therapy for Chronic Periodontitis
Regular Home Use of Dual-light Photodynamic Therapy in the Management of Chronic Periodontitis
Study Overview
Status
Intervention / Treatment
Detailed Description
Periodontitis is a chronic inflammatory disease leading to a progressive loss of the tooth-supporting apparatus. The disease is strongly associated with deranged biodiversity patterns in dental plaque.
The Lumoral is a CE-marked medical device developed to provide a potent, targeted antibacterial action on dental plaque in a home environment. The device mechanism of action is antibacterial photodynamic therapy. The device is used by swishing a mouth rinse, which has a strong adherence to dental plaque. The plaque-adhered photoactive mouth rinse can be activated by a simple to use light applicator. The antibacterial efficacy far exceeds chlorhexidine, without side effects in a longterm use. Preliminary results have shown a promising anti-inflammatory response in addition to plaque reduction.
Ninety (90) stage I-III periodontitis patients are randomized to Lumoral treatment group or control group. Both groups shall receive mechanical plaque control by scaling and root planning (SRP) and standard oral hygiene instructions for electric toothbrush, interdental brush, and dental floss use. All the patients shall be assessed for the clinical periodontitis status. These assessment and analyses shall be performed at baseline, at 3 months and at 6 months after the treatment.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Lumoral Treatment (Study group)
Subjects will receive detailed instructions for the use of Lumoral treatment -device and Lumorinse -tablets. Subjects will be instructed to use the Lumoral treatment -device and follow the protocol five to seven (5-7) times a week. Regular use shall be defined as frequency of a minimum of twice a week. Standard oral hygiene instructions will be provided verbally and in writing. In addition, an electric toothbrush will be provided to all subjects. |
The investigational Lumoral treatment -device provides a constant and repeatable application which can be done at home and is easily available.
All subjects in the study group will receive their own Lumoral treatment -device and Lumorinse-mouth rinse tablets for the complete duration of the study.
Other Names:
Both groups shall be given oral and written instructions for twice-daily standard oral hygiene self-care.

Active Comparator: Standard of care (Control group)
Standard oral hygiene instructions will be provided verbally and in writing.
In addition, an electric toothbrush will be provided to all subjects.
