Abstract:
Objectives:To evaluate changes in probing depth, bleeding on probing, and three-dimensional plaque distribution after using an interdental brush for three months.
Methods:This was a split-mouth design, examiner-blinded, randomized controlled trial. Fifteen patients were randomly assigned to use an interdental brush between their maxillary left or right 1st and 2nd premolar. They were instructed not to use an interdental brush on the opposite side for three months. Probing depth, bleeding on probing, bleeding on using an interdental brush, gingival recession, and plaque distribution were assessed at baseline and after three months.
Results:After using an interdental brush for three months, 4.26±15.16% of plaque on interdental surfaces decreased. Bleeding on probing and bleeding on using an interdental brush also decreased by 16.67% and 40%, respectively. The size of interdental areas increased by 0.16 mm when using an interdental brush. There were no statistically significant changes in probing depth or gingival recession.
Conclusions:An interdental brush is an effective interdental cleaning aid that reduces interdental plaque and decreases inflammation of interdental soft tissues.
