The role of modeling in designing new treatment protocols and instruments is discussed. A computer program for modeling laser-tissue interaction named Latis is described. Interactions are divided into the processes of laser propagation, thermal effects, material effects, and hydrodynamics. Full coupling of the processes is taken into consideration. Applications in photothermal and photomechanic...

This paper describes the use of thermographic methods during laser/tissue interaction. The efficacy of laser application on human tissue is partly dependent on the skills and experience of the laser operator. The laser effects of photothermolysis occurring in the dermis are difficult to predict. With the intervention of an infrared radiometer it is possible to see the thermal distribution at th...

Lasers have been used for oral soft tissue dental procedures for more than 30 years, and have been researched since the middle 1960s.1-4 Their reported benefits over conventional treatment modalities include: reducing numbers of appointments, reducing stress, improving visibility, improving patient comfort, and reducing complications. Critics have commented that most of these advantages are ane...

Selective photothermal interaction using dye enhancement has proven to be effective in minimizing surrounding tissue damage and delivering energy to target tissue. During laser irradiation, the process of photon absorption and thermal energy diffusion in the target tissue and its surrounding tissue are crucial. Such information allows the selection of proper operating parameters such as dye con...

Today, lasers are widely used in biology and medicine, and the majority of health centers and hospitals utilize modern laser systems for diagnosis and therapy applications. Researchers have introduced different medical applications for different lasers used in surgeries and other medical treatments. Medical lasers can be categorized in both diagnosis and therapy branches. Main difference betwee...

Laser-tissue interaction is of great interest due to its significant application in biomedical optics in both diagnostic and treatment purposes. Major aspects of the laser-tissue interaction which has to be considered in biomedical studies are the thermal properties of the tissue and the thermal changes caused by the interaction of light and tissue. In this review paper the effects of light on ...

introduction :   co 2 (carbon dioxide) laser application in circumcision, for cutting and coagulation, has been reported to have excellent results. also, tissue glue has been reported to have advantages over sutures for approximation of wound edges. most previous studies focused on comparisons between co 2 laser and scalpel, or between tissue glue and sutures. this study prospectively compared ...

the purpose of these case reports is to analyze the results of gingivectomy and gingival troughing to determine the evidence on the effectiveness of laser-assisted soft tissue procedures and soft tissue management in aesthetic dentistry.the patients in these case reports underwent 980 nm diode laser assisted gingivectomy and gingival troughing to achieve immediate hemostasis and moisture contro...
