Detailed Description
Lumoral treatment 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, strongly adhering to dental plaque. The plaque-adhered photoactive mouth rinse can be activated by a simple use light applicator. The antibacterial efficacy far exceeds chlorhexidine, without side effects in long-term use. Preliminary results have shown a promising anti-inflammatory response in addition to plaque reduction.

This early-stage study is designed to determine the efficacy of the Lumoral method in periodontitis patients. Improved supragingival plaque control can help to also sustain subgingival plaque management in the long term. In addition, the device might have a photobiomodulation effect on periodontal tissues.
