Re ! cet item me pose problème :

"l'émail est un tissu acellulaire" VRAI

mais les améloblastes alors ? il y a quelque chose que j'ai du mal à saisir là ? 

une petite explication est la bienvenue ?

En effet l'émail est un Tissu dur, minéralisé, acellulaire, les améloblastes disparaissent (ce qui fait que l'émail ne se régénère pas !)
