Low Level Laser Therapy for Hyposalivation

Low level laser treatment has proved to be effective for a wide range of oral pathologies including oral dryness, but the literature still lacks reports of clinical trials and protocols. The aim of this study was to evaluate the effects of two different laser wave lengths on salivation of patients suffering from hyposalivation. This with purpose to possibly find the optimum laser wavelength for the treatment, and to determine the better protocol for the patients suffering from hyposalivation. This study included 30 patients whose major salivary glands were treated with low intensity diode laser BTL2000 (Medical Technologies, s.r.o., Czech Republic) during 10 consecutive days. Patients were randomly assigned in two groups, each of 15 patients, and treated with LLLT of 830 nm and LLLT of 685 nm, respectively. The whole unstimulated and stimulated saliva was measured in graduated tubes each day during 10 days, before and after laser treatment and 10th day after treatment was ended.
