The dental industry is associated with significant environmental impacts so there is a growing need for eco-friendly practices in dentistry. This study aimed to assess dental interns' knowledge and practices regarding eco-friendly dentistry before and after the implementation of the environmental educational program.
An interventional quasi-experimental study (one group pre-test-post-test design) was conducted on 69 intern dentists at the Faculty of Dentistry Alexandria University. Assessment of knowledge and practices related to eco-friendly dentistry was performed three times: before, after two months, and after four months of the educational program.
The mean age of participants was 23.72 years; 56.5% were males; 89.9% hadn't received prior training on eco-friendly dentistry; and 40.6% obtained their green dentistry information from online websites. The educational program significantly improved their knowledge (median score percentage went from 50% before the intervention to 81.82% and 81.82% after two and four months of the conducting of the educational program, respectively.) and eco-friendly practices (median score percentage increased from 58.33% before the intervention to 75% and 66.67% after two and four months of the intervention, respectively) and the differences were statistically significant (p < 0.05). Significant positive correlations were noticed between knowledge and practice either before or after the training program (p < 0.05).
There was a significant improvement in knowledge and practices of the participants after the implementation of eco-friendly educational program. The successful educational program in early career is important in reducing waste generation and resource consumption, as well as potential cost savings on the long run.

牙科行业对环境有重大影响，因此牙科领域对环保做法的需求日益增长。本研究旨在评估环境教育项目实施前后牙科实习生对环保牙科的知识和实践情况。
对亚历山大大学牙科学院的69名实习牙医进行了一项干预性准实验研究（一组前后测设计）。在教育项目开始前、两个月后和四个月后，对与环保牙科相关的知识和实践进行了三次评估。
参与者的平均年龄为23.72岁；56.5%为男性；89.9%之前未接受过环保牙科培训；40.6%从网站获取绿色牙科信息。教育项目显著提高了他们的知识水平（干预前中位数得分百分比为50%，教育项目实施两个月和四个月后分别为81.82%和81.82%）和环保实践（干预前中位数得分百分比从58.33%分别提高到干预两个月和四个月后的75%和66.67%），差异具有统计学意义（p<0.05）。在培训项目前后，知识与实践之间均存在显著正相关（p<0.05）。
实施环保教育项目后，参与者的知识和实践有了显著改善。在职业生涯早期成功开展教育项目对于减少废物产生和资源消耗以及长期潜在的成本节约非常重要。
