摘要：

The purpose of this study was to determine the laser side effects of cutting bone with a short-pulsed (80 mus) CO2 laser. To approximate living conditions, 10 samples of cortical bone and 10 rib segments were prepared immediately after sacrificing the pigs. The laser incisions were not accompanied with carbonization. At the border of the incisions, two narrow zones of damage were noted: an amorphous, intensively stained zone of 1-3 mum width and a wider, also sharply demarcated but faintly stained zone of 7-10 mum. A broader zone of about 50 mum was characterized by empty lacunae and osteocyte damage. The histological results indicated only minimal damage to bone ablated at the specified parameters.
