Efficacy of vital home bleaching

The nightguard vital bleaching technique has become a very common and accepted procedure for many dental practitioners. Much has been written about the procedure's history, safety and technique; little has been done to quantify the specific color changes of teeth resulting it. This clinical study attempted to give a numerical value to the color change through the use of a light transmission densitometer. The maxillary teeth of twenty-five patients were treated as the control. A significant whitening was observed for a majority of the patients during the four-week duration of the study.
