Abstract: 

Aim of this prospective, randomised, controlled clinical trial was to use the modified bass technique (MBT) and a specific brushing sequence to investigate whether two types of instruction methods lead to differences in plaque reduction and whether plaque reduction is related to technique adoption.

Ninety-eight participants were randomly assigned to three groups: (1) control, no instruction; (2) verbal instruction by means of a leaflet; and (3) verbal instruction supported by demonstration, no leaflet. Brushing performance was video monitored. Plaque score (Turesky modified QHI (T-QHI)) was measured at baseline, afterwards participants received instructions. After 2 weeks, T-QHI was measured for a second time, and participants were re-instructed. After another 2 weeks, T-QHI was measured for a third time.

At baseline, T-QHI did not differ between groups ((1) 1.99 +/- 0.51, (2) 1.90 +/- 0.51, (3) 1.93 +/- 0.56). The second measurement revealed an improvement of T-QHI in the instructed groups and in the non-instructed control group ((1) 1.80 +/- 0.47, (2) 1.58 +/- 0.58, (3) 1.64 +/- 0.58; n.s. between groups); in the intervention groups, remotivation achieved no further improvement ((1) 1.72 +/- 0.48, (2) 1.52 +/- 0.58, (3) 1.50 +/- 0.69; n.s. between groups and compared to second measurement). Improvement of T-QHI was not related to proper performance of technique or brushing sequence. Those who fully adopted the brushing technique, the sequence or both did not have lower plaque scores.

Technical performance and effectiveness were not linked.

Within the study setting, the MBT was not effective in reducing plaque scores. The general recommendation of the MBT should be re-evaluated in further studies.
