Detailed description
The aim of this study is to evaluate the clinical and microbiological effects of Bifidobacterium animalis subsp. lactis DN-173010 containing yoghurt as an adjunct to mechanical periodontal treatment. Thirty chronic periodontitis patients were randomized into 2 groups. As adjunctive to MPT, Group 1 consumed 2×108 CFU/day of Bifidobacterium animalis subsp. lactis DN-173010 containing probiotic yoghurt while Group 2 natural yoghurt once daily for 28 days. Subgingival plaque samples were obtained from 2 periodontal sites with probing pocket depth (PPD) of 4≤PPD\<7 mm via paper-points at baseline, 28th day, 3rd month. Samples were cultured to evaluate total viable count (TVC), the proportions of obligate anaerobes (OA) and Bifidobacterium species (B) (TVC%). The full-mouth recorded clinical parameters were plaque index, gingival index, PPD, bleeding on probing, and clinical attachment level.

Masking description
Individuals and doctor were blinded to the study groups allocation. Before statistical analysis, the blind study coordinator broke the code to allocate the indivuals to the groups.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Probing Depth | 28 days | Probing depth is defined as the distance from the free gingival margin to the bottom of the periodontal pocket. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Gingival Index | 28 days | Each of the buccal, mesial, lingual and distal surfaces of the gingival tissues is given a score of 0-3. (0 = Normal gingiva. 1 = Mild inflammation - slight change in color, slight edema. No bleeding on probing. 2. Moderate inflammation - redness, edema and glazing. Bleeding on probing. 3. Severe inflammation -marked redness and edema.) |
| Plaque Index | 28 days | Each of the four surfaces of the teeth (buccal, lingual, mesial and distal) is given a score from 0-3. (0 = No plaque in the gingival area. 1 = A film of plaque adhering to the free gingival margin and adjacent area of the tooth. The plaque may only be recognized by running a probe across the tooth surface. 2 = Moderate accumulation of soft deposits within the gingival pocket, on the gingival margin and/or adjacent tooth surface, which can be seen by the naked eye. 3 = Abundance of soft matter within the gingival pocket and/or on the gingival margin and adjacent tooth surface. Tendency to spontaneous bleeding.) |
| Bleeding on probing | 28 days | Bleeding on probing is defined as presence of bleeding from gingival sulcus during the probing of this area via periodontal probe. |
| Clinical attachment level | 28 days | The distance from the cementoenamel junction to the bottom of the periodontal pocket. |
| microbiological parameters | 28 days | The number of obligate anaerobic bacteria and Bifidobacterium anaerobes |
