Ventilator-associated pneumonia (VAP) is a life-threatening condition in critically ill patients receiving mechanical ventilation. The incidence of VAP in varies between 9% and 45% with mortality rates of up to 50% . It is accompanied by an increase both in length of stay in intensive care units ICU and healthcare.
The aim of this trial was to investigate the effect of a powered toothbrush on colonization of dental plaque by ventilator-associated pneumonia (VAP)-associated organisms and dental plaque removal.
The study was a parallel-arm, single-centre, examiner- and analyst-masked randomized controlled trial. Patients were recruited within 48-hrs of admission. The test group had oral hygiene performed by a nurse with a powered toothbrush with the control group using a sponge toothette. This was conducted 4-times per day for 2-minutes with groups receiving 20 ml, 0.2% chlorhexidine mouthwash at each time point.
- A low prevalence of respiratory pathogens throughout with no statistically significant differences between groups
- A highly statistically significantly reduction in dental plaque was produced by the powered toothbrush compared with the control treatment

Powered toothbrushes are highly effective for plaque removal in intubated patients in a critical unit and should be tested for their potential to reduce VAP incidence and health complications.
