The following section presents a separate analysis for each dependent variable: GI, PI and BoP from baseline (T0; immediately before placement of the fixed appliance) to 12-months (T3; Mixed-effects multiple linear regression for Gingival Index.
Model includes fixed effects for tooth and its interaction with time and toothbrush.Mixed-effects multiple linear regression for bleeding on probing.
Model includes fixed effects for tooth.Mixed-effects multiple linear regression for Plaque index.
Model includes fixed effects for tooth.The interaction observed between the specific tooth in the participant’s mouth and gingival index scores.The interaction observed between the specific tooth in the participant’s mouth and plaque index scores.The interaction observed between the specific tooth in the participant’s mouth and bleeding on probing scores.Spaghetti plots for mean Gingival Index, bleeding on probing, and Plaque Index to show changes over time and per tooth in the mouth.
