A survey of 1,179 dentists in Kansas and Missouri was mailed in an effort to determine their current use of computers. There was a completed return of 458 surveys (39 percent). Of those responding, 64.4 percent indicated they had a computer in their home or office. Of those with computers, 73 percent were IBM or IBM compatible, 11.5 percent were Macintosh and 15.5 percent were other. Comparison of this survey with a similar survey completed in Indiana indicates that computer usage by dentists appears to be increasing but not at the same rate as the advances in computer technology.
