A Randomized Controlled Trial for Evaluation of the Effectiveness of Oral Irrigator and Interdental Floss for Plaque Control in Children with Visual Impairment.

Aim: To evaluate the effectiveness of oral irrigator and interdental floss as adjuncts to manual tooth brushing in 8-16 years old children with visual impairment.

Materials And Methods: A three-arm, parallel-group randomized controlled trial with blinded outcome assessment was carried out with the inclusion of 90 institutionalized children with visual impairment of age 8-16 years. They were equally allocated to three groups: group I: tooth brushing along with interdental flossing, group II: brushing along with a powered oral irrigator, and group III: brushing alone (control).
