Resumo: Purpose: To evaluate temperature changes of pulpal chamber (PC) and infrared blocking bleaching gel on dental surface (SUR) during the activation with photocuring units with halogen lights that emit radiation in the infrared (IR) range. Methods: The bleaching gels Whiteness HP Maxx (IR-blocker – MX) and Whiteness HP (control – CON) were used in ten maxillary central incisors. Light-activation was performed by using the photocuring units (FC) Optilight (600mW/cm2, OP) or Jet Lite (1200mW/cm2, JL) with four 40s-activation procedures with no interval (total time: 3min 20s). The temperature was measured each 40s using a digital thermometer with two type K thermocouples placed inside the PC and on dental surface (SUR). Data were analyzed with 3-way ANOVA (gel type – GT, FC and activation time) and Tukey’s test. Results: A significant effect was found for the main factors FC and GT, and for their interaction. The means (SD) (in Celsius degree) were: PC:[GT={MX-6,38(3,25)a, CON-7,70(2,91)b}, FC={OP-5,51(2,54)a, JL-8,56(2,93)b}]; SUR: [GT={CON-9,85(3,89)a, MX-14,21(7,76)b}, FC={OP-7,32(2,50)a, JL-16,74(5,82)b}]. Conclusions: MX resulted in lower pulp chamber heating and higher gel heating than the control group. JL promoted greater heating than OP. Key words: Dental bleaching; halogen light; infrared light

Key words: Dental bleaching; halogen light; infrared lightObjetivo: Avaliar a temperatura da câmara pulpar (CP) e do gel clareador bloqueador de infravermelho na superfície dental (SUP), durante a ativação com fotopolimerizadores com lâmpadas halógenas que emitem radiação na faixa do infravermelho (IV). Metodologia: Os géis clareadores Whiteness HP Maxx (com bloqueador de IV – MX) e Whiteness HP (controle – CON) foram aplicados em 10 incisivos centrais superiores. A ativação com luz foi realizada com os fotopolimerizadores (FP) Optilight (600mW/cm2, OP) e Jet Lite (1200mW/cm2, JL), sendo quatro ativações de 40s, sem intervalo (total de 3min e 20s). As temperaturas foram aferidas a cada 40s com um termômetro digital com dois termopares tipo K, um no interior da CP e outro na superfície dental (SUP). Os dados foram analisados com ANOVA a 3 fatores (tipo de gel – TG, FP e tempo de ativação) e teste de Tukey. Resultados: Houve efeito significativo de TG e FP e para a interação FP/TG. As médias (DP) (em graus Celsius) foram: PC:[GT={MX-6,38(3,25)a, CON-7,70(2,91)b}, FC={OP- 5,51(2,54)a, JL-8,56(2,93)b}]; SUR: [GT={CON-9,85(3,89)a, MX-14,21(7,76)b}, FC={OP-7,32(2,50)a, JL-16,74(5,82)b}]. Conclusões: O gel bloqueador de IV resultou em menor aquecimento da CP e maior aquecimento do gel que o controle. O FP Jet Lite promoveu maior aquecimento que o Optilight.
