      abstract = {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.},
