Description of intervention(s) / exposure
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.

Statistical methods / analysis
The required sample size for this study is calculated to be a total of 165 (1:1:1 Group A: Group B: Group C). This calculation includes provision for a 10% attrition rate, two tailed tests, type 1 error of 5%, and will have 80% power to detect any significant difference between Group A and Group C. This calculation is based from an API score reduction of 25% in the intervention arm of Ziebolz, et al 2009 study. However, due to our exclusion criteria of less than or equal to 59% API score, we will expect to see a 40% decrease in Group A, compared to 15% in Group C. This current study is powered to detect a difference in percentage proportion of those between Group A and Group C however, has poor power to detect a difference between Group B and Group C.
The statistical plan for this study will be determined prior to study completion. Analysis of the difference in API will be according to the intention-to-treat principle where participants are analysed in the arm they have been allocated. The level of statistical significance will be set at p-value <0.05. The primary analysis will be an adjusted analysis of variance performed to assess differences between groups for API scores between baseline and follow-up. Covariates used for adjusted analyses will include age, sex, highest PSR code, level of education, smoking status, and number of teeth. Subgroup analysis of the intervention effect and age, sex, education, ethnicity, and cardiovascular disease presentation (coronary heart disease, heart failure, heart transplant list, heart transplant receiver) will also be explored. Outcome measures available at baseline (PSR, SBI and API) will also be included in the statistical model. An unadjusted analysis will be performed to assess differences between groups using a X2 test for binary (categorical) outcomes and independent sample t-tests for continuous outcomes.

Summary
Brief summary
The link between oral health and cardivascular disease has been proven. Currently, there is no oral health education within cardiac rehabilitation facilities within Western Sydney Local Health District. Patients living with cardiovasuclar disease and gum disease are at an increased risk of a future cardiac event. Introducing oral health education into this vunerable poopulation may reduce their gum disease and with it their future cardiac event risk.
