Effects of Active Oxygen Toothpaste in Supragingival Biofilm Reduction: A Randomized Controlled Clinical Trial

Table 1

Comparison between groups according to the gingival index at buccal and lingual aspects.

Gingival index (GI)
Groups	Time
	W −1 (mean ± SD)	W0 (mean ± SD)	W1 (mean ± SD)	W12 (mean ± SD)	W18 (mean ± SD)
CT	0.12 ± 0.16	0.59 ± 0.49	0.07 ± 0.10	0.12 ± 0.12	0.12 ± 0.12
BM	0.08 ± 0.14	0.62 ± 0.51	0.07 ± 0.12	0.13 ± 0.13	0.06 ± 0.07

W −1: preclinical trial; W0: established gingivitis; W1: 1^st evaluation after brushing for 1 week; W12: evaluation of brushing for 12 weeks; W18: evaluation of brushing for 18 weeks. For each group, indicates significant difference between the times based on Tukey’s test.
