The present invention relates to a method for improving adherence durability of a dental restorative material using pulse plasma and a method for improving adherence of dentin using pulse plasma drying. The method for improving adherence durability of a dental restorative material using pulse plasma according to the present invention is not only applicable to all of various kinds of dental restorative materials, but can also maintain an excellent level of adherence durability even in poor oral environments, making it possible to use the dental restorative materials for a long period of time. In addition, the method for improving dentin using pulse plasma drying according to the present invention can maintain an excellent level of adherence to a dental restorative material even in poor oral environments, making it possible to use the dental restorative material for a long period of time. The method makes it easy to adjust the organic materials and moisture included in the dentin, which have a large influence on the adherence, and maintains as large an area of contact with collagen as possible. Accordingly, the maximum area of contact is obtained while moisture can be adjusted more freely, in order to secure adherence, making it possible to provide a more excellent dentin attaching method.La présente invention concerne un procédé damélioration de la durabilité dadhérence dun matériau de restauration dentaire au moyen dun plasma pulsé et un procédé damélioration de ladhérence de la dentine au moyen dun séchage par plasma pulsé. Le procédé damélioration de la durabilité dadhérence dun matériau de restauration dentaire au moyen dun plasma pulsé selon la présente invention est non seulement applicable à lensemble des différents types de matériaux de restauration dentaire, mais peut également maintenir un excellent niveau de durabilité dadhérence, même dans des environnements buccaux médiocres, ce qui permet dutiliser les matériaux de restauration dentaire pendant une long
