Color range of natural teeth

Several investigations on the distribution of color in natural teeth have been made. Some evaluations were made visually, based on matching the teeth with porcelain sample (ref. 239) and Munsell tabs (ref.239), while others were determined by spectrophotometric measurements (ref.241-244).
