title: Conservation of human research teeth by controlling cavity depth.
abstract: In order for the dental profession to obtain reliable data as to whether new or experimental restorative materials and adjunct agents are more or less irritating to pulp tissues than dental products currently in use, pulp studies at the national and international level are being standardized to enhance corroboration. The purpose of this study was to reduce the number of human teeth required in any experimental pulp toxicity study by controlling the problem of cavity depth. Many valuable teeth are wasted by making cavity preparations that are either too shallow or too deep, with consequent pulp exposures. This needs to be corrected.
