Evaluation of Clinical Effectiveness and Subjective Satisfaction of a New Toothbrush for Postsurgical Hygiene Care: A Randomized Split-Mouth Double-Blind Clinical Trial

Table 2

Influence of the type of surgery (fixed factor) and of the toothbrush (random factor) on Gingival Index (GI) at 30 days. GI mean values and Standard Deviation (SD) are reported for both test (TB1) and control toothbrushes (TB2). Generalized Linear Model applied considering GI at baseline as covariate.

	GI: 30 days
GI baseline	0.002
Surgery	0.719
Toothbrush	0.299
Surgery and toothbrush	0.050
Mean (SD) TB1	0.27 (0.15)
Mean (SD) TB2	0.55 (0.29)
