Design outcomes

Primary

Measure	Time frame
Willingness-to-Pay (WTP) will be used to quantify patient's preferences for the three forms of information. WTP is recognised as representative of how consumers respond to health care decision making. WTP is measured using a contingent valuation approach (a hypothetical scenario used to elicit preferences from participants) collected at the first visit (the patient's dental check-up appointment)	—

Secondary

Measure	Time frame
1. Clinical communication measured by the Communication Assessment Tool (CAT), completed by patients after receiving the risk information at V1 2. Self-reported behaviour change between V1, and 6 and 12 months post-intervention: 2.1. Oral hygiene is measured by self report tooth-brushing frequency, duration of tooth-brushing and frequency of interdental cleaning 2.2. Use of fluoride is measured by self report fluoride toothpaste prescribed by the dentist and fluoride mouth-rinse 2.3. Dietary sugar intake is measured by self report frequency of consumption of sugary foods/drinks and frequency of adding sugar to hot drinks tea/coffee 2.4. Smoking is measured by self report smoking information 2.5. Self-rated oral health status measured using a self report rating scale at V1 and 6 and 12 months 3. Clinical outcomes: 3.1. Basic Periodontal Examination (BPE) collected by dentists concentrating on conversions between codes 1 (bleeding) and 0 (health) between V1 and V2/3 3.2. Plaque Percentage Index (PPI) measured on QLF images (?R30) – change between V1 and V2/3 3.3. Number of tooth surfaces affected by early caries – change between V1 and V2 / 3 measured on QLF images 3.4. Where early carious lesions are present – change in lesion volume (?Q) between V1 and V2 / 3 measured on QLF images	—
