These experiments aimed to investigate and compare the nature of the zone of secondary damage in calvarial bone defect prepared with either XeCl excimer laser or the erbium: YAG laser light at 75mJ/pulse. Material & Methods: These experiments were conducted in vitro, using excised calvarial bone, which was examined by environmental scanning electron microscopy (ESEM). Results: The excimer laser produced a morphologically different defect in bone. It was smooth surfaced with extensive scattering of debris and cracking. Were the Erbium: YAG laser slot showed less charring than XeCl excimer laser and the surface was smooth with microspheratic pattern. Energy dispersive x-ray analysis showed that the carbonisation and Ca/P ratio were higher in XeCl excimer laser defects compared to erbium: YAG laser defects.
