Title: A randomized clinical trial on the effect of powered toothbrushing and an antimicrobial mouthrinse on dental plaque, pathogenic microorganisms and health of stroke survivors during rehabilitation
Abstract: A combination of motor, sensory, and cognitive deficits often occurs after stroke and has sustained impacts on activities of daily living. Due to compromised abilities after stroke, an individual is unable to perform oral self-care to a satisfactory level. Stroke-associated orofacial deficits affect the ability to clear food debris out of the oral cavity and exacerbate poor oral hygiene. Consequently, increased dental plaque result in oral cavity acting as a reservoir not only for oral infections, but also systemic health problems such as aspiration pneumonia, which is one of the most common post-stroke infections. Recent evidence suggests a link between aspiration pneumonia and oral hygiene. Powered toothbrushing is likely to be more effective than conventional manual toothbrushing for disabled patients in attaining adequate oral hygiene. Chlorhexidine gluconate is considered to be the most effective chemical agent in dental plaque control. A combination of mechanical and chemical interventions has proven efficacy in reducing dental plaque and associated oral pathogens. Acknowledging the importance of oral health after stroke, we are now conducting a randomized clinical trial to evaluate the effectiveness of powered tooth brushing and a chlorhexidine anti-microbial mouthrinse in reducing dental plaque accumulation and oral pathogens among stroke patients during out-patient rehabilitation.
