TLDR
It is shown that the temperature of porcine bone samples can be maintained to a constant value within the range of 40°C-75°C and real-time feedback computer control between a noncontact sensor and a CO2 laser operating at a typical repetition rate within the 5-20 kHz range is shown.Abstract:
In this paper, we show that the temperature of porcine bone samples can be maintained to a constant value within the range of 40°C–75°C. For this temperature range, it was also shown that a porcine bone sample could be kept at a given temperature within a fraction of a degree Celsius. This method relies on a real-time feedback computer control between a noncontact sensor and a CO2 laser operating at a typical repetition rate within the 5–20 kHz range. Results are shown for domesticated porcine bones that strongly absorb the CO2 radiation at λ=10.6 μm.read more

Conventional versus CO2 laser-assisted treatment of peri-implant defects with the concomitant use of pure-phase beta-tricalcium phosphate: a 5-year clinical report
TL;DR: It is concluded that the treatment of peri-implantitis may be accelerated by using a CO2 laser concomitant with soft tissue resection, and with respect to long-term results in augmented defects, there seems to be no difference between laser and conventional decontamination.

On the physical rationale of laser induced hyperthermia
TL;DR: Methods for introducing hyperthermia include electromagnetic radiation in the radiofrequency and microwave region as well as ultrasonic waves and the use of lasers emitting within the visible and near infrared part of the spectrum has the potential to initiate a local elevation of the temperature.

Fundamental Interactions of Laserswith Dental Hard Tissues
TL;DR: By carefully choosing the parameters it is possible to produce a laser that can selectively remove carious tissue, leading to a conservative cavity preparation, and also providing protection against later caries challenges.
