Resumo
Background and Objectives: Er,Cr:YSGG laser radiation is
slightly better absorbed by hydroxiapatite than the Er:YAG laser
and this fact may indicate its use as a benefit tool for caries
prevention. This study was performed to investigate the surface
and intrapulpal temperature during Er,Cr:YSGG laser
irradiation at sub-ablative conditions.
Study Design/Materials and Methods: Twenty five extracted
human molar teeth were selected and divided into five groups,
according to the following Er,Cr:YSGG irradiation conditions
without air-water spray: 1.0; 1.5; 2.8; 5.6; 8.5 J/cm2
. During laser
irradiation, surface temperature was measured using a
thermocamera (ThermaCAM-FLIR SC3000). The pulpal
temperature was also monitored by means of a thermocouple type
T (copper-constantan) placed in the pulpal chamber.
Results: The surface temperature increased directly with the
energy density of laser, and returned to its initial temperature
3 seconds after laser irradiation. Laser irradiation resulted in a
non-significant intrapulpal temperature increase ( 1C) in all
parameters tested. Temperature rise values were compared using
analysis of variance (ANOVA) with alpha equals 0.05.
Conclusions: The application of laser irradiation did not induce
detrimental surface and pulpal temperature variations at the
utilized parameters, being suitable for caries prevention.
