The data analysis allowed to list the conditions for applying photobiomodulation that could lead to therapeutic effects, safety, and efficacy in treating the rosacea. Based on clinical and experimental studies accessed, photobiomodulation could decrease rosacea hallmarks and symptoms by decreasing of pro-inflammatory factor expression, inflammatory infiltration and immune cells, and promoting extracellular matrix remodeling.

The drug loading capacity, stability and safety of liposomes were characterized. Singlet oxygen quantum yield (Φ<sub>Δ</sub>) was measured under simulated tumor microenvironment conditions. In vitro phototoxicity was evaluated using A549 human lung adenocarcinoma cells. Liposomes have a high drug loading capacity, good biocompatibility and good long-term stability. Under tumor-simulated conditions, Φ<sub>Δ</sub> was significantly improved, increasing from 0.210 for free ICG to 0.507. The liposomes demonstrated remarkable phototoxic effects on A549 cells (90.5% cell death under combined PDT/PTT vs. 15% for free ICG).

Without proper cooling, high frictional heat can be generated inside the bone during drilling which may be detrimental for osteocyte survival. Mechanical fracture of bone near a drill bit surface can also impede the osseointegration process. Our new concept is to use a rapid laser ablation model for dental implant osteotomy preparation to minimize adverse effects on the bone from mechanical and thermal damages. A mathematical model was developed to detail the temperature and energy distribution within bone under laser irradiation. Thermal and energy transfer in bone was predicted during laser interaction using finite element simulations. Various parameters of laser irradiation settings were analyzed. The best designed laser irradiation condition was derived from our theoretic modeling in terms of thermal and mechanical characteristics for osteotomy. We also validated our theoretical prediction with an ex vivo animal bone study. We conclude that a smooth and clean surface was successfully formed with laser power of 10 W, scanning speed of 600 mm/s, and scanning interval of 20 μm. We also achieved the highest removal rate of 0.63 mm<sup>3</sup>/s. Our finite element model demonstrated that it could effectively predict the temperature and energy distribution during an osteotomy drilling.
