NCT Number: NCT05425784
This early-stage research is designed to determine the efficacy of the Lumoral method in chronic periodontitis patients. Improved supragingival plaque control can help to also sustain the subgingival plaque management in the long term. In addition, the device might have a photobiomodulation effect on periodontal tissues.

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.
Healthy volunteers accepted: No
Only the study team can determine whether someone qualifies for participation.

Other names: Lumorinse mouth rinse
Both groups shall be given oral and written instructions for twice-daily standard oral hygiene self-care.
Other names: Electric toothbrush provided

Time frame: 3 months
Clinical improvement of periodontitis measured by probing pocket depth (PPD) at 3 months based on the absolute values of PPD. All clinical parameters will be recorded with the help of a graded periodontal manual probe (for example, North Carolina 54B or UNC15 probe (Hu-Friedy Mfg. Co., LLC) or similar device) with a maximum force of 0.25 N.

Time frame: 3 months
Clinical improvement in periodontal microbiological pathogens at 3 months compared to baseline. The microbiological evaluation is the Quantification of periodontopathic bacteria by 16S rRNA sequencing analysis. Microbiological sample will be collected using so called Iso Taper Paper Points, size-20 (VDW GmbH) from selected gingival/periodontal pockets with maximum initial probing depth. The paper points will then be be placed into sterile, small-aliquot containers, and immediately stored at -20°C until analysis.

Patient related objectives: Improvement in oral-related quality of life measurement (OHIP-14) questionnaire at baseline, at 3 months compared to baseline.
Fourteen items of OHIP are divided into seven dimensions: functional limitation, physical discomfort, psychological discomfort, physical disability, psychological disability, social disability, and handicaps. Grading is based on answering a five-scale questionnaire from 'Never' to 'Very often'.
