Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Orthodontic treatment with fixed appliances can be necessary to correct malocclusions in adolescence or adulthood. It its known that orthodontic treatment induces aseptic pseudo-inflammatory reactions. However, studies could show that an increase of certain inflammatory cytokines during orthodontic treatment correlated with a higher risk of root resorption. Moreover, it has been shown that orthodontic treatment leads to a dysbiosis of the oral microbiome especially during the first 3 months of the orthodontic treatment. This could be a potential risk factor as the inflammation of periodontitis during an orthodontic treatment could favor root resorption and progressive destruction of the periodontal apparatus.

Probiotics are already used successfully as an adjuvant therapy in the treatment of periodontitis to improve clinical parameters and to reduce local inflammation. However, there are only a few studies that investigated the influence of probiotics during an orthodontic treatment.

Therefore, the aim of our study is to investigate if the daily intake of lozenges containing probiotics versus placebo lozenges during the first 3 months of orthodontic treatment with fixed appliances can improve clinical parameters, reduce local inflammation, systemic inflammation and prevent a dysbiosis of the oral microbiome.

Participants Investigators
Study participants, meeting the inclusion criteria and not fulfilling the exclusion criteria, will be assigned to the study group or to the control group using a randomization plan. Randomization plan will be generated by the Center for Clincal Studies of the University Hospital of Erlangen. The lab manager will prepare storage boxes, in which exactly 168 lozenges will be stored. Half of the boxes will contain test-lozenges (study group), half or them will contain placebo-lozenges (control group). The storage boxes for the test and the placebo group will be identical and blinded. The storage boxes will be labelled with pseudonyms in accordance to the randomization plan generated by the Center for Clinical Studies. Therefore, study participants will not have knowledge of the group affiliation. The collection of the samples and the measuring of the clinical parameters will be performed by one orthodontist, who will be blinded to the randomization of the study participants.
