Implementing Environmental Sustainability Educational Intervention in Dental Hygiene Instruction

Area of Science:

• Environmental Science
• Dental Education
• Public Health

Background:

• The global climate crisis poses significant public health risks.
• The dental industry is a major contributor to waste generation in the United States.

Purpose of the Study:

• To evaluate dental hygiene students' knowledge and perceptions of environmentally sustainable dentistry (ESD).
• To assess the impact of an educational intervention on students' understanding and attitudes toward ESD.

Main Methods:

• A pilot study involved second-year dental hygiene students (n=34) at UNC-CH.
• Participants completed pre- and post-intervention surveys and a follow-up assignment.
• Paired t-tests and qualitative analyses were used to assess changes in knowledge and behavior.

Main Results:

• A statistically significant increase in knowledge scores was observed after the educational module (p < 0.0005).
• Over 90% of participants felt the assignment enhanced their learning experience.
• Qualitative data indicated students applied ESD concepts and adopted less wasteful behaviors in clinical practice.

Conclusions:

• Educational interventions in dental hygiene programs can effectively improve knowledge of environmentally sustainable habits.
• Integrating ESD into the curriculum can foster behavioral changes and reduce waste in dental practice.
