Efficacy of computer-assisted, 3D motion-capture toothbrushing instruction.
OBJECTIVE
The objective of this study was to compare the efficacy of computer-assisted TBI using a smart toothbrush (ST) and smart mirror (SM) in plaque control to that of conventional TBI.


METHODS
We evaluated the plaque removal efficacy of a ST comprising a computer-assisted, wirelessly linked, three-dimensional (3D) motion-capture, data-logging, and SM system in TBI. We also evaluated the efficacy of TBI with a ST and SM system by analyzing the reductions of the modified Quigley-Hein plaque index in 60 volunteers. These volunteers were separated randomly into two groups: conventional TBI (control group) and computer-assisted TBI (experimental group). The changes in the plaque indexes were recorded immediately, 1 week, 1 month, and 10 months after TBI.


RESULTS
The patterns of decreases in the modified Quigley-Hein plaque indexes were similar in the two groups. Reductions of the plaque indexes of both groups in each time period were observed (P < 0.0001), and the effects of TBI did not differ between the two groups (P = 0.3803). All volunteers were sufficiently motivated in using this new system.


CONCLUSIONS
The reported new, computer-assisted TBI system might be an alternative option in controlling dental plaque and maintaining oral hygiene.


CONCLUSIONS
Individuals can be motivated by the new system; meanwhile, comparable effects of controlling dental plaque can be achieved.
