Interdental plaque reduction after use of different devices in young subjects with intact papilla: A randomized clinical trial

Objectives To determine the efficacy of 4 different oral hygiene regimens involving adjunctive interdental cleaning devices in unsupervised young subjects with intact interdental papilla. Material and methods Sixty periodontally healthy subjects were randomly allocated to 4 groups following different oral hygiene regimens (T-7): use of manual toothbrush alone; manual toothbrush plus dental floss; manual toothbrush plus interdental brushes; and manual toothbrush plus rubber interdental picks. Oral hygiene instructions (OHI) were given. One week after (T0), professional supragingival scaling and polishing was performed, and subjects were then reseen every 2 weeks (T14 and T28). At T-7, T0, T14 and T28, full-mouth plaque score (FMPS), full-mouth bleeding score (FMBS) and angulated bleeding index (AngBI) were taken. Results During the first week (T-7/T0 unclean phase), FMPS decreased significantly in all groups except the group using dental floss. At T28, a significant decrease in FMPS (P
