- Brief Summary
The aim of the present study was to investigate the potential beneficial effects in volunteer young adults of orally administered L. reuteri (DSM 17938 and ATCC PTA 5289) on gingival inflammation. The null hypothesis was that no difference would be manifested by probiotic therapy regarding the conventional mechanical treatment (without probiotic administration).
- Detailed Description
Aim. To investigate the potential beneficial effects in volunteer young adults of orally daily administered L. reuteri (DSM 17938 and ATCC PTA 5289) on gingival inflammation. The null hypothesis was that no difference would be manifested by probiotic therapy regarding the conventional mechanical treatment (without probiotic administration).
Methods. A randomized controlled parallel clinical trial was conducted in sixty young adults (18-35 yrs old) with chronic marginal gingivitis for one month. Initially, both study groups underwent conventional mechanical periodontal therapy/oral anti-plaque hygiene. However, the experimental group additionally received the administration of two daily tablets, containing both L. reuteri strains, for 30 days, while the control group did not. Different clinical outcome variables (plaque (PI) and gingival (GI) indices, bleeding on probing (BOP), and crevicular fluid volume (CFV)) were recorded and compared between the study groups, both at baseline and at the end of the interventions, 30 days later. Statistical descriptive and inferential tests were performed (data distribution normality, Student's t, and Wilcoxon-Mann-Whitney tests).

Group Intervention Description Probiotic group L. reuteri (DSM 17938 and ATCC PTA 5289) in form of oral tablets The experimental group received conventional mechanical periodontal therapy and oral anti-plaque hygiene training, plus the administration of two daily tablets, containing both L. reuteri strains, for 30 days.
- Primary Outcome Measures
Name Time Method Gingival index 0, 7, 14, 21 and 30 days. The Gingival Index (GI) scores each site on a 0 to 3 scale, with 0 being normal and 3, being severe inflammation characterized by edema, redness, swelling, and spontaneous bleeding.
Plaque index 0, 7, 14, 21 and 30 days. The plaque index assesses the amount of dental plaque visible on the vestibular and lingual surfaces of all teeth, except the third molars. The bacterial plaque developer solution was used to define cumulative amounts of plaque with criteria from 0 to 5.
Bleeding on probing 0, 7, 14, 21 and 30 days. BOP describes bleeding induced by gentle manipulation of the tissue. The probing is typically completed to the depth of the gingival sulcus, or the area between the gingiva and the tooth.
Crevicular fluid volume 0, 7, 14, 21 and 30 days. Gingival crevicular fluid is an inflammatory exudate derived from the periodontal tissues. It is composed of serum and locally generated materials such as tissue breakdown products, inflammatory mediators, and antibodies directed against dental plaque bacteria.
