Abstract
The aim of this study was to determine the possible temperature increase on ischolar_main surface of deciduous human teeth after intra-ischolar_main canal laser irradiation with different chopped modes to clarify the thermal safety of these modes. fifteen freshly extracted unrestorable deciduous molars were used. Immediately after extraction, teeth cleaned, ischolar_main canal perpetrated, laser irradiation was done in mesial ischolar_main using dual wavelengths 980/810 nm InGaAs diode laser (using a 200 μm fiber, 800mW output power. Room temperature were raised in the laboratory to 37C to simulate body temperature, for each tooth three chopped program were used successively: 25ms on 75ms off, 50ms on and 50ms off, and 75ms on 25ms off. Each round laser irradiated for 5 seconds then 10 seconds pause. At the very last second temperature was measured using infrared thermometer. This procedure for the three groups was repeated but with non-stop laser irradiation with no cooling intervals. It was concluded that 30/70 ms layout can be used safely to assist ischolar_main canal disinfection.
