The effects of two baking-soda toothpastes in enhancing mechanical plaque removal and improving gingival health: A 6-month randomized clinical study.

Purpose: To compare the effectiveness in reducing plaque and gingivitis of two fluoride toothpastes containing baking soda (35% and 20%) with a fluoride toothpaste control.

Methods: 319 subjects, who met entry criteria, participated in this single-center, three-cell, double-blind, randomized, parallel-group clinical study. Gingival Index (MGI), Gingival Bleeding Index (GBI), and Plaque Index (PI) were assessed at baseline, and after 6 weeks, 3 and 6 months.
