At 12 weeks, the Mann-Whitney U Test indicated that the difference between the groups in terms of toothbrush area was statistically significant (P =. The difference in plaque scores at 12 weeks was statistically significant (P =.
The BT group showed significantly smaller percentages of BoP than the NI group at 4 (BT = 12.4% and NI = 31.4%) and 12 (BT = 11.6% and NI = 43.8%) weeks.

The analyses were performed using the SAS software (version 9.4 SAS Institute, Cary, NC).įorty-eight participants were eligible to participate and were randomly assigned to one of the two groups (N = 24). The statistical significance between the cohorts' BoP and their plaque score results was assessed via hierarchical logistic regression. The toothbrushes of all participants were photographed and assessed by two blinded examiners using the ImageJ software. Clinical measurements (probing depth, plaque score, BoP) of each tooth were recorded at 4 and 12 weeks.

The test group (BT) was instructed on how to use the BIT, and the control group (NI) received no brushing technique instructions. Only the subjects who presented with bleeding on probing (BoP) were enrolled. The primary objective of this randomized controlled clinical trial was to investigate the effect of the Bass Intrasulcular Technique (BIT) on reducing gingival inflammation at 4 and 12 weeks compared with the toothbrushing techniques commonly used.Īfter receiving ethical approval from the Tufts Health Sciences Institutional Review Board, 55 subjects were invited to participate in the study.
