This study will compare six clinically relevant cleaning protocols for their effects on surface roughness and microplastic release, and assess the relation between these outcomes.\n\n" "Methods: Sixty PETG aligners (Erkodur 1.0 mm) will be randomly allocated to six groups (n=10): distilled water, dry toothbrush, 1450-ppm sodium-fluoride toothpaste with toothbrush, sodium perborate effervescent tablets, 0.12% chlorhexidine gluconate, and ultrasonic cleaning. Each protocol will be applied twice daily for 14 days (28 cycles). Surface roughness (Ra, µm) will be measured before and after treatment using a stylus profilometer; change in roughness (ΔRa) is the primary outcome. Five specimens per group will undergo field-emission scanning electron microscopy and Raman spectroscopy for surface characterization. Effluent will be vacuum-filtered through 0.45-µm membranes, and retained particles will be characterized by field-emission scanning electron microscopy and Raman spectroscopy. One-way ANOVA with Tukey’s HSD and correlation analysis will be used (p<0.05).\n\n" "Expected Results: Toothbrushing with fluoride toothpaste is expected to cause the greatest roughness increase and particle release; distilled water and chlorhexidine are expected to cause less alteration. Effervescent tablets and ultrasonic cleaning are expected to show intermediate effects.\n\n" "Conclusion: This study will provide comparative evidence on cleaning-related surface degradation and microplastic release from PETG orthodontic aligners.
