PURPOSE This laboratory research study was conducted to evaluate three manual toothbrushes for their ability to remove artificial plaque from interproximal sites. MATERIALS AND METHODS Interproximal access efficacy (IAE) was evaluated using a pressure-sensitive artificial plaque substrate placed around simulated anterior and posterior teeth with(More)
OBJECTIVE A new toothbrush, with elongated fine bristles and a vibrating bristle field, has been designed and developed. In this study, the new product was compared to two commercially available powered, oscillating-rotating toothbrushes for efficacy using a laboratory method that has been predictive of clinical plaque removal. METHODS Interproximal(More)
The rhythm of renal sodium and potassium excretion was measured in 4-h-intervals in 12 subjects. Each person exhibited clear circadian variations of each variable with a maximum between 8 a.m. and 4 p.m. In each subject and for both circadian rhythms the oscillation mean was correlated to the range of oscillation (amplitude). Increase in sodium or potassium(More)
