, Les deux images SEM de l'émail WT (avec et sans application NaOCl) ont indiqué qu'il existait une couche d'émail imprégnée d'amorces contenant probablement la couche de frottis couvrant les tiges d'émail mordancés (illustration 7A et 7D). Le traitement de l'émail AmelxKO avec NaOCl avant le traitement SEP(self-etching primer) a semblé modifier de manière significative la surface de l'incisive, car l'image SEM de NaOCl plus SEP présentait une couche globulaire de matrice qui n

, Pour l'émail incisif AmelxKO et Mmp20KO, il était difficile d'observer s'il existait des couches d'émail imprégnées d'amorces contenant une couche de frottis sur les surfaces d'émail (illustration 7B, 7C, 7E, 7F) à partir des images SEM de SEP uniquement et NaOCl plus SEP. CONCLUSION L'étude des états de surface, en fonction des différentes techniques d'éviction carieuse, a révélé des états de surface amélaires différents, Lorsque l'émail Mmp20KO a été traité avec NaOCl avant le traitement SEP, la surface de l'incisive semblait légèrement modifiée par rapport au traitement SEP uniquement (illustration 7C et 7F)

, Les études ont révélé que le protocole de collage était identique selon les techniques invasives et peu invasives de curetage, les résultats convergent tous vers l'utilisation du mordançage à l'acide orthophosphorique pour améliorer le potentiel d'adhésion. Néanmoins, des techniques comme le laser entraine un état de surface similaire à un émail mordancé, ainsi l'étape de mordançage pourrait être mise de
