Abstract :
This paper presents a novel approach to enhancing the efficiency of dental laser treatments through the
integration of laser-tissue interaction models and optimization algorithms. Laser-tissue interaction is modeled using the heat conduction equation, which simulates temperature distribution within biological tissues during laser irradiation. The model incorporates essential parameters such as tissue thermal diffusivity, specific heat capacity, and laser energy deposition. To optimize laser parameters such as intensity and exposure time, a gradient-based optimization algorithm is employed. The objective is to achieve a target tissue temperature conducive to effective ablation while ensuring safety constraints to prevent tissue overheating are met. Numerical simulations demonstrate the effectiveness of the proposed approach. The optimization algorithm successfully adjusts laser power to achieve the desired temperature with minimal error, while maintaining tissue temperatures below the safety threshold. The model’s accuracy is validated through comparisons with analytical solutions for simplified cases, confirming its robustness and reliability. Additionally, a surface plot of temperature evolution over time provides valuable insights into the dynamic response of tissues to laser energy. These findings highlight the potential of combining advanced modeling techniques and optimization algorithms to enhance the precision and efficacy of clinical dental laser applications
