Abstract
SYNOPSIS IN INTERLINGUA CHARACTERISTICAS PHYSIO-CHIMIC DE ACTIVE E ARRESTATE LESIONES CAEIOSE.—Le duo plus obvie differentias clinic inter dentinas a cariositate arrestate e active es le augmentos del duritate superficial e del pigmentation in le lesiones arrestate. Analyses per medio de un specialmente disveloppate technica a absorption infrarubie monstrava un augmento del contento organic e un declino del contento inorganic in dentina cariose, sed le methodo provideva nulle information relative al natura del pigmento in le dentina a cariositate arrestate. Analyses spectral a flamma revelava in dentina a cariositate arrestate in comparation con dentina a cariositate active un augmento de Ca++ per un factor de 1,64. Le mesme methodo monstrava que le dentina a cariositate arrestate habeva minus Ca++- que dentina normal.
