Toothbrushing instruction and mouth health educational videos targeting patients within cardiac rehabilitation clinics.

Participants will be randomised into one of 3 arms as follows: Group A) Individualised oral hygiene instruction (OHI) partnered with an oral health education video package, Group B) oral health education video package only, Group C) Control arm consisting of usual care within the cardiac rehabilitation clinic (no oral health education). Oral hygiene instruction will be delivered using results from the clinical assessment as a guide for patient focus by a trained research assistant and/or dental/oral health students at baseline and the 6 week follow up. The advice will take no longer than 10 mins and will be reinforced by the outcome assessor (qualified oral health therapist) at the 12-week follow up. Toothbrushing or interdental cleaning instructions will be given in accordance with the oral hygiene standard operating procedure (SOP) designed specifically for the study. Oral health clinical measurements taken at each visit should show if the patient has changed their habits as per the advice, and if they are continuing to use these throughout the study. Oral health education video package will include videos that are advertisement free; and created by either government bodies, or relevant health bodies such as the Australian Dental Association (ADA). They will contain content related to oral health and cardiovascular health, and if randomised into Group A or Group B, the same videos will be repeated at each visit. This will again be monitored for change via oral health clinical measurements at each visit. The video package will contain approximately 4-6 videos which are between 1-2 minutes of duration each. At the final follow up (12-weeks), after completing clinical measurements and the follow-up questionnaire, Group B and Group C will be given tailored OHI. Group C will also be shown the video package.
