Shifting the Focus
• Individual lifestyle approach to health policy• Emphasis on “at risk” populations• One-on-one clinical interventions
• Social policy approach • Shared behavioural risks of NCDs• Broad health promotion models

Challenges in Uptake of Technologies
North America→ Private market→ Heavy technology dependence→ Minimal accountability→ Clinicians' autonomy→ Regional, socioeconomic
disparities→ Lack/scarcity of CPGs→ High operative costs→ Competitive environment
Barriers and Incentives in Uptake of New Technologies by Dental Professionals
