Processes for forming dental materials and device

Abstract

Processes for forming dental materials that include applying a first hardenable dental composition (e.g., a dental adhesive) to a surface followed by applying a second hardenable dental composition (e.g., a dental composite) to the first hardenable dental composition on the surface. The first and second hardenable dental compositions are hardened such that the second hardenable composition is substantially completely hardened prior to complete hardening of the first hardenable composition.

1 . A dental composition hardening light comprising: 
 a housing;    a first light source located within the housing, the first light source emitting light in a first wavelength range;    a second light source located within the housing, the second light source emitting light in a second wavelength range; and    a controller operably connected to the first light source and the second light source, the controller controlling emission of light from the first light source and the second light source.    
   
   
       2 . The light of  claim 1  wherein the first light source emits only light within the first wavelength range.  
   
   
       3 . The light of  claim 1  wherein the first light source emits light with wavelengths outside of the first wavelength range.  
   
   
       4 . The light of  claim 1  wherein the first light source is capable of emitting light with wavelengths in both the first wavelength range and the second wavelength range.  
   
   
       5 . The light of  claim 1  wherein the first wavelength range is about 380 nm to about 450 nm.  
   
   
       6 . The light of  claim 5  wherein the second wavelength range is about 450 nm to about 520 nm.  
   
   
       7 . The light of  claim 5  wherein the first wavelength range is about 380 nm to about 520 nm.  
   
   
       8 . The light of  claim 1  wherein the first light source comprises a light-emitting diode.  
   
   
       9 . The light of  claim 1  wherein the second light source comprises a light-emitting diode.  
   
   
       10 . A process of hardening a dental composition comprising applying radiation from a light comprising: 
 a housing;    a first light source located within the housing, the first light source emitting light in a first wavelength range;    a second light source located within the housing, the second light source emitting light in a second wavelength range; and    a controller operably connected to the first light source and the second light source, the controller controlling emission of light from the first light source and the second light source.    
   
   
       11 . The process of  claim 10  wherein the first light source is capable of emitting light with wavelengths in both the first wavelength range and the second wavelength range.  
   
   
       12 . The process of  claim 10  wherein the first light source comprises a light-emitting diode.  
   
   
       13 . The process of  claim 10  wherein the second light source comprises a light-emitting diode.
