PURPOSE This review of six clinical trials provides a comprehensive overview of the results of statistical analyses to explore between-brush differences, specifically in the lingual, gingival marginal, and approximal ("hard-to-clean") areas, in post-brushing plaque removal of oscillating-rotating (O-R) power toothbrushes compared to either a marketed sonic power toothbrush or a manual toothbrus...

Acoustic emission transducers were used to study the brush/rotor interface of a homopolar motor as a function of design parameters such as speed and load. The results indicate that acoustic emission is well suited for in situ monitoring of brush wear and rotor conditions, and for analyzing the tribological phenomena occurring at the brush/rotor interface. r 2007 Elsevier Ltd.

BACKGROUND Oral squamous cell carcinoma (OSCC) has a remarkably high incidence worldwide, and a fairly serious prognosis. This is encouraging further research into advanced technologies for non-invasive methods of making early diagnoses, ideally in primary care settings. Method : In this article, the available objective Non-imaging methods for diagnosing OSCC have been reviewed. MEDLINE, EMBASE...
