Background: Stagnant oral biofilm can lead to oral diseases gingivitis and periodontitis. If left untreated, periodontitis can lead to destruction of the supporting structures of the teeth and trigger systemic inflammation. As early as 21-days after ceasing toothbrushing, inflammatory markers associated with atherosclerosis the primary cause of cardiovascular disease (CVD), can be detected in blood samples. Good oral hygiene is the most effective way to prevent periodontitis, thereby reducing CVD risk. The primary aim of this study is to assess whether individualised oral hygiene instruction partnered with a digital oral health education (DOHE) package can improve the oral health of patients attending cardiac rehabilitation.
Method: A total of 165 participants will be recruited from two Sydney cardiac rehabilitation clinics into this dual centre, single blind, parallel design, randomised controlled trial. Baseline oral health clinical examinations and self-report questionnaires are completed before participants are randomised into one of 3 arms, in a 1:1:1 ratio. The examination and questionnaires are repeated at 6- and 12-weeks. The primary analysis will be an adjusted analysis of variance performed to assess differences between groups for approximal plaque index scores between baseline and follow-up.
Conclusion: Information involving oral health’s role in heart health within the cardiology space is almost non-existent. This is the first study to implement DOHE to patients attending cardiac rehabilitation clinics. By building oral disease prevention strategies for these individuals, they will have success in future health outcomes.
