Results
-
One article studied the SBS of the brackets bonding on the teeth after internal bleaching treatments [40].
-
one didn’t test the SBS value in detail [41].
-
one was rejected because of the authors conducted the analysis on group of teeth which were divided in mesial and distal part and treated only on the distal surface with bleaching and bonding agents so a correct and equal assessment of SBS was not possible [42].
-
The last one studied the decalcification effect around the brackets [43].
