Brief Summary

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

The purpose of this study is to evaluate the clinical efficacy of a probiotic lozenge containing Limosilactobacillus reuteri as an adjunct to the periodontal non-surgical treatment of patients with stage II, grade A, B and C, generalized periodontitis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The main purpose of this study is to assess the effect on disease progression of the probiotic Limosilactobacillus reuteri as an adjunct in the non-surgical periodontal treatment in patients with stage II, grade A, B and C, generalized periodontitis: evaluated by Bleeding on Probing (BoP) - Lindhe, 1972. The secondary purpose is to evaluate the effect of this probiotic on the values of Plaque Index (PI) - Silness \& Löe, 1964; Gingival Index (GI) - Löe \& Silness, 1963; Probing Pocket Depth (PPD), Clinical Attachment Level (CAL) - Ramfjord, 1959, when compared to a negative control product.
