Knowledge Awareness And Practices Of Aligner Disposal Among Orthodontist, General Dentist And Patients Undergoing Aligner Orthodontic Therapy: A Cross Sectional Study

Introduction: Clear Aligners offer a discreet orthodontic treatment alternative, made from materials like PET and TPU, known for their transparency and durability. However, their nonbiodegradable nature raises environmental concerns. This study aims to assess knowledge, awareness and practices regarding Clear Aligner waste among orthodontist general dentist and patients undergoing Clear Aligner therapy to promote effective disposal methods and reduce environmental impact. Methodology: The study included postgraduate orthodontic students, practicing orthodontists, general dentists providing aligners, and patients undergoing aligner therapy. Excluded are those treated with local brands. A 15-item questionnaire assessing knowledge and practices on aligner disposal was validated using face and content validity and administered via Google Sheets to relevant participants. Results: The study analyzed the mean age, gender distribution, and knowledge regarding aligner disposal among orthodontists, general dentists, and patients. Orthodontists had a mean age of 25.9 years, while general dentists averaged 25.1 years, and patients had a broader age range with a mean of 26.4 years. Males predominated in all groups, especially among patients (82.8%). Significant differences in knowledge and awareness were noted, with orthodontists outperforming general dentists and patients in understanding disposal practices. Overall, orthodontists scored highest in knowledge (3.07), awareness (3.48), and practice (2.91), indicating a need for improved education for general dentists and patients. Conclusion: In conclusion, orthodontists, general dentists, and patients differ in aligner disposal knowledge, awareness, and practices. Patients had the lowest grades across all dimensions, whereas orthodontists understood and followed disposal techniques best. Targeted educational initiatives are needed to close the knowledge-practice gap, especially for general dentists and patients. Environmental protection and responsible dental care require better disposal education.
