Sažetak
Laser devices have gained in importance since the eighties and they are often claimed to be omni-use instruments. Diode lasers offer an interesting – but not unlimited – field of application in modern dentistry including periodontology, endodontics and soft tissue treatment. LLLT (Low Level Laser Therapy) is the application of red and near infra- red light over injuries or lesions to improve wound and soft tissue healing, reduce inflammation and give relief for both acute and chronic pain. LLLT is used to increase the speed, quality and tensile strength of tissue repair ; resolve inflammation and relieve pain (analgesia). When the correct intensity and treatment times are used, red and near infrared light reduces oxidative stress and increases ATP. This improves cell metabolism and reduce inflammation. Low level laser therapy effects are biochemical and not thermal and cannot cause heating and thereby damage to living tissue. These so called soft lasers offer the dentist several interesting fields of application. The antimicrobial photodynamic therapy (aPDT) is a non-thermic light-induced inactivation of cells, microorganisms or molecules. "Antimicrobial" photodynamic therapy targets pathogenic microorganisms. Using a dye, the bacteria that cause infections are stained, sensitized and destroyed following exposure with light of a suitable wavelength and energy density. A decisive role plays the „photosensitizer“, a coloring solution (e.g. Toluidin Blue, Methylene Blue etc.). The oxygen atoms in the color molecules are activated by irradiation of appropriate light. They initiate singulet conditions, which have a toxic effect on the cells. LaserHF device was used in multiple clinical indications, surgical and therapeutical, at the Department of Oral surgery, School of Dental Medicine, University of Zagreb. Wide range of clinical indications including soft tissue oral surgery, endodontic surgery, dental implants exposure in second stage surgery, therapeutic approach of periimplant diseases (conservative and surgical), therapeutic application in cases of intraoral and labial herpes, recurrent aphthous ulcers, other ulcers and other soft tissue pathological changes. No side effects or complications of surgery, LLLT or a PDT performed using HF Laser have been found in our clinical research during follow-ups. All patients reported absence of pain, minimal postoperative discomfort and maximum comfort due to absence of sutures and bleeding.
