  1. 1. The model was also adjusted for other variables without statistical significance and higher p values: Systemic disease, Daily diet frequency intake, Thick dental plaque, Dental floss use, F toothpaste use, Dental-pain/discomfort medication/food-type change during last 3 months
  2. 2. The variable “Need of assistance to perform oral hygiene” was omitted due to collinearity
