Abstract

Objective

The current study aimed to evaluate the temperature rise in the dental pulp during treatment of dentin with 445-nm diode laser.

Materials and methods

Ten single-rooted human premolar teeth were randomly enumerated into 1 to 10. Teeth were embedded in a resin block, and a thermocouple was inserted into the pulp chamber. Cervical third of the crown were irradiated with 1, 1.5, 2, 2.5, and 3 W at time of irradiation of 10, 15, 30, and 60 s (CW, Non-contact mode), while immersed in a 37 °C thermal bath.

Results

The maximum mean temperature rise in the dental pulp was 10.6 °C achieved after irradiation with 3 W for 60 s and the lowest temperature increase achieved was 0.3 °C with 1 W for 10 s.

Conclusion

Using the 445-nm diode laser, 0.2–1 W, CW up to 60 s; 1.5 W, CW up to 15 s; 2 W, CW, 10 s; and 2.5 W,CW, 10 s are considered biologically safe parameters for the dental pulp during dentine hypersensitivity treatment.
