impact of regular home use of lumoral dual-light photodynamic therapy on plaque control and gingival health

Conditions: Periodontitis; Plaque, Dental; Plaque Induced Gingivitis

Summary: this early-stage study is designed to determine the efficacy of the ce-approved, antibacterial, dual-light lumoral method in 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.

dental plaque triggers changes in gingival health, which results in slight swelling and bleeding from the gingival margin and causes gingivitis. supragingival dental biofilm control can be achieved by mechanical and chemical means. toothbrushing is effective in reducing levels of dental plaque (van der weijden \& slot 2015). it removes plaque from flat, accessible surfaces but is less effective at the gingival margins and in approximal areas, where the accumulation of residual plaque encourages gingivitis and deterioration of periodontal health. effective toothbrushing is also depending on a number of factors, e.g., age, knowledge, manual dexterity and motivation. oral hygiene instructions and patient motivation in oral hygiene practices should be an integral part of the patient management during all stages of periodontal treatment (tonetti et al., 2015). oral health practice of individuals affects their gingival and periodontal health. 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. 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 the subgingival plaque management in the long term. in addition, the device might have a photobiomodulation effect on periodontal tissues. forty (40) patients are randomized to the lumoral treatment group or the control group. both groups shall receive standard oral hygiene instructions for sonic toothbrush, interdental brush, and dental floss use. all the patients shall be assessed for the clinical periodontal status including visible plaque index (vpi), bleeding on probing (bop) and probing pocket depth (ppd). in addition, ammp-8 mouth rinse test and microbiological analysis of gingival pockets will be performed. digital photographs after staining will be taken. these analyses shall be performed at baseline and at 4 weeks after the treatment.

Eligibility criteria:
inclusion criteria: * at least 18 years old * agreement to participate in the study and to sign a written consent form exclusion criteria: * presence of any physical limitation or restriction that might restrict lumoral use * pregnancy or lactation
