Effect of dentin pre-treatment on smear layer thickness: an ultrastructural study
The aim of thisstudy was to investigate the morphological changes of etched dentin by sodium hypochlorite (NaOCl) pre-treatment method applied for different durationsand smear layer (SL)thickness. Sixtyhuman molars were used in this study and sectioned at thecoronal part to expose a flat dentin di...
