The root portions of 80 extracted intact human maxillary central incisors were sectioned with a carborundum disk approximately 2 mm below the cementoenamel junction perpendicular to the long axis of the teeth. Two bleaching agents containing heat\u2010enhancing colorant was applied to the labial surface. Light\u2010curing units used were a conventional halogen (40 s), a high\u2010intensity halogen (30 s), a light\u2010emitting diode unit (40 s), and a diode laser (15 s). The temperature rise was measured in the pulpal chamber with a J\u2010type thermocouple wire that was connected to a data logger. Ten specimens were used for each system and bleaching\u2010agent combination. Differences between the starting temperature and highest temperature reading were taken and the calculated temperature changes were averaged to determine the mean value in temperature rise. Temperature rise values were compared using two\u2010way analysis of variance (ANOVA) at a preset \u03b1 of 0.05. Temperature rise varied significantly depending on curing unit and diode laser used. The diode laser induced significantly higher temperature increases than any other curing unit (11.7\u00b0C). The light\u2010emitting diode unit produced the lowest temperature changes (6.0\u00b0C); however, there were no statistically significant differences among the curing units and there were no statistically significant differences between bleaching agents. Light activation of bleaching materials with diode laser caused higher temperature changes as compared to other curing units and the temperature rise detected was viewed as critical for pulpal health. \u00a9 2004 Wiley Periodicals, Inc.
