AB  - The purpose of this study was to determine possible pathologic changes that might result from bleaching vital tetracycline stained teeth. Temperatures inside the pulps of three dog teeth were shown to respond to external applications of heat, hydrogen peroxide, and a combination of both. An initial temperature was recorded inside the pulps and temperature rises were noted in response to all of the conditions when applied to the buccal enamel surfaces of the teeth. Hydrogen peroxide was applied at three concentrations and shown to be more effective in raising pulpal temperatures at the higher concentrations. When heat and hydrogen peroxide were applied together, pulpal temperatures were noted to stabilize at four centigrade degrees below the enamel surface temperatures. Fourteen additional teeth, four from the same dog and ten from a second, were exposed to a bleaching procedure that involved application of hydrogen peroxide heated to about forty-one centigrade degrees for one-half hour at one week intervals for four consecutive weeks. Histologic sections of these teeth removed one week following the final bleaching were not suitable for study due to fixation artifact.
