Complex Plaque Control by Robot Testing of Four Different Toothbrushes

Objectives: The best plaque control in elderly/periodontitis patients is still disputed. Therefore, it was the aim of study (i) to compare plaque removal efficacy in a complex clinically validated robot programme including manual, powered and interdental toothbrushes, (ii) to differentiate crown versus root plaque control, and (iii) to summarize clinical conclusions because of validated programmes.
Methods: The robot was programmed simulating 2min brushing, force 3.5N, movement rotating on replicated human teeth in anatomic position. Synthetic plaque simulation was used.
Automated Planimetrical Plaque Assessment was executed at 24 crown and 6 root fields per tooth. The test MTB Inava15/100 (Pierre Fabre, France) was compared to Curaprox1560 (Curadent, Switzerland), and PTB InavaHybrid was compared to PTBInavaHybrid plus gauge-adapted IDBs (Pierre Fabre, France[SM1] ).
All four tests were performed 7 times. Kolmogorov-Smirnov-test was applied to test 11 variables for normal distribution, H0 was rejected. Therefore, Wilcoxon-Mann-Whitney-test was used.
Results: Brushing programmes were strictly identical. No statistical differences could be detected in plaque control at buccal and lingual smooth surfaces. Mesially and distally, next to gumline and at all root fields Inava was clearly superior to Curaprox, however, inferior to combined brushing with InavaHybrid followed by the IDBs Blue/Yellow. Consequently, this combination was statistically significantly better than Curaprox at all risk fields/areas except next to gumline lingually. Most hidden areas distally of tooth roots showed plaque removal from incisors to second molars of 75.2-99.4% in analysis of single teeth. Range of total brushing efficacy was MTB Inava 71.5% and MTB Curaprox 57.3%, PTB InavaHybrid 66.4% and PTB+IDB 81% Plaque control by soft brushes depends on number of filaments (Inava versus Curaprox).
Conclusions: Complex plaque control by powered vibrating/rotating toothbrushing followed by adapted interdental brushing of exposed root areas is highly efficient.
Clinically validated robot testing and planimetrical plaque assessment at 4 sites of all teeth demonstrates standardized biophysical brushing actions.
