Objectives:
The objectives of this study were to evaluate and compare the effectiveness of an advanced oral hygiene care programme (AOHCP) and a conventional oral hygiene care programme (COHCP) in improving oral hygiene, and reducing gingival bleeding among patients with stroke during outpatient rehabilitation.
Methods:
Subjects were randomized to receive (i) the COHCP comprising a manual toothbrush, toothpaste, and oral hygiene instruction, or (ii) the AOHCP comprising a powered toothbrush, 0.2% chlorhexidine mouthrinse, toothpaste, and oral hygiene instruction. Dental plaque, gingival bleeding, and other clinical oral health outcomes were assessed at baseline, the end of the clinical trial, and the end of observation period. Development of infectious complications was also monitored.
Results:
Participants of both programmes had a significant reduction in the percentages of sites with moderate to abundant dental plaque (p<0.001) and with gingival bleeding (p<0.05). Those in the AOHCP had significantly less plaque and gingival bleeding than those in the COHCP controlling for other factors at the end of the clinical trial period (both p<0.001) and the observational period (plaque: p<0.05, gingival bleeding: p<0.01).
Conclusions:
Although both oral hygiene care programmes were effective in terms of plaque and gingival bleeding control, the AOHCP was more effective than the COHCP in reducing dental plaque and gingival bleeding.
Clinical Significance:
This study highlighted the value of oral hygiene programmes within stroke outpatient rehabilitation and provides evidence to advocate for the inclusion of oral hygiene care programmes within stroke outpatient rehabilitation for patients with normal cognitive abilities.
