An interventional study of Lumoral Treatment and Standard oral health instructions in Orthodontic Appliance Complication, Plaque, Dental and Gingival Inflammation, sponsored by Koite Health Oy. Completed at 1 site in Sweden. Open to participants aged 15 Years to 18 Years. Per ClinicalTrials.gov, last updated 2026-01-21.

This study is designed to determine the efficacy of the Lumoral method on oral health in adolescents undergoing fixed orthodontic treatment. 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.
Orthodontic treatment is one of the most common dental treatments in children and adolescents. The use of fixed orthodontic appliances makes it difficult for the patients to keep their oral hygiene to an optimum level of cleanliness. Poor oral hygiene attracts significant plaque accumulation around the fixed orthodontic treatment appliances, and subsequent white spot lesions can occur rapidly, usually on the cervical and middle third of the buccal surfaces of bracketed teeth. Patients with the fixed orthodontic treatment appliances have an increased risk of caries and gingivitis.
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 (aPDT). 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. Preliminary results have shown a promising anti-inflammatory response in addition to plaque reduction.
Forty (40) subjects undergoing fixed orthodontic treatment are randomized to the Lumoral treatment group or the control group. All subjects shall receive polishing and oral hygiene instruction. All patients shall be assessed for the clinical measurements including visible plaque index (VPI), bleeding on probing (BOP), and orthodontic plaque index (OPI) at baseline and at 4 weeks and 12 weeks after baseline. In addition, microbiological analyses shall be performed at baseline and at 12 weeks after baseline.

Change in Visible plaque index (VPI)
* A full-mouth assessment, measured at six sites per tooth. * Dichotomous scoring to each site of the tooth as plaque "1 present" and "0 absent" * VPI is reported as the percentage (%) of sites with plaque. * Calculation formula: number of sites with plaque/ 6 times number of teeth
Time frame: 12 weeks
Change in Bleeding on probing (BOP)
* A full-mouth assessment at six sites per tooth (mesiobuccal, buccal, distobuccal, mesiolingual, lingual, distolingual) * Gingival bleeding is considered as positive if bleeding occurs within 15 seconds after gentle probing with a probe at the sulcus. * Dichotomous scoring to each site of the tooth as bleeding "1 present" and "0 absent" * BOP is reported as the percentage (%) of sites with positive findings. * Calculation formula: number of bleeding sites/ 6 times number of teeth
Time frame: 12 weeks
Change in Orthodontic plaque index (OPI)
* The OPI indicates the presence of plaque around the multibracket appliance after staining the teeth with a plaque-disclosing solution. * Using the data from the digital photographs, selected six (6) index teeth that bear an adhesively bonded bracket will be evaluated. * The status is indicated as a score from 0 to 4. The degree of plaque accumulation on each aspect of the bracket base and the condition of the adjacent marginal gingivae are assessed: 0 = No plaque deposits on the tooth surfaces surrounding the bracket base 1. = Plaque deposits on one tooth surface at the bracket base 2. = Plaque deposits on two tooth surfaces at the bracket base 3. = Plaque deposits on three tooth surfaces at the bracket base 4. = Plaque deposits on four tooth surfaces at the bracket base and/or gingival inflammation indicators (plaque deposits near the gingiva do not necessarily have to be present)
Time frame: 12 weeks
Change in periodontal microbiological flora
Microbiological sampling and analysis: * Quantification of periodontopathic bacteria by 16S rRNA sequencing analysis. * Microbiological samples can be collected using Iso Taper Paper Points, size-20 (VDW GmbH) from the plaque on the surface of the teeth, using a curette if needed. The paper points can be placed into sterile, small-aliquot containers, and immediately stored at -20°C until analysis. * 16S rRNA sequencing can be performed at a qualified laboratory assigned by the study sponsor
Time frame: 12 weeks
