Laser surgery in dental medicine

Advanced technologies have nowadays made their way into medicine. Until only ten years ago laser techniques were almost unsuitable for this use – bulky equipment, very high cost, limited functionality, etc. It was the introduction of diode lasers that brought about the change. The modern equipment is very compact and approximately 10 times more affordable. Diode lasers are among the high-energy lasers with wave length of 700-1100 ηm, thus allowing pain-free and bloodless coagulation and soft tissue evaporation. This practically includes almost all minor soft-tissue surgical interventions in the oral cavity.

So the availability of both types of equipment in a dental office would cover most of the procedures that were once performed through the standard surgical techniques and equipment. The widely advertised high-energy lasers such as Nd YAC, Erbium, CO2 for treatment of hard dental tissues (as in caries) are not advanced enough and they are difficult if not impossible to use in certain areas. These lasers are only applicable for treatment of surface and easily accessible cavities where the results are comparable to those of using ultrasound or piezo- equipment although the latter can successfully be used also for the treatment of deep and hard to access cavities. The dental office is equipped with a DenLase manufactured by China Dahleng Group which specializes in the production of laser wave beams supervised and certified by TÜV. The apparatus is certified in UK for use in EU. DenLase is a diode laser equipment utilizing the latest available technologies for semiconductor laser equipment for soft tissue surgery and therapy. The basic DenLase component is a laser diode made of aluminum gallium arsenide / AlGaAs /. It is electricity activated. The diode emits monochrome light which can be focused, defocused and transferred through flexible optical fibers. The wave length is 810 ηm. The light is invisible, with non-ionizing thermal radiation which does not induce any changes in the cell DNA. DenLase is air cooled. The safety of the operator, supporting staff and the patient is ensured by several methods for cutting off the emission /network switch and pedal/, emergency switch and protective glasses. DenLase is a laser system suitable for use with the following indications: abscess, adenoma, ulcers, biopsies, bio-stimulation, teeth whitening, tooth crown lengthening, gingival pockets curettage, desensitization of sensitive dental tissue, drainage, epulis, excision, fibroma, fistulae, frenectomy, gingivectomy, gingivoplasty, hemangioma, hemostasis, herpes, hyperplasia, implant disclosure, incisions, root canal sterilization, pulp coagulation, mucocele, operculectomy, papilloma, peri-implantitis, sulcus retraction, sulcus sterilization, fistula canals, vestibuloplasty.
