Aim of the study: to compare effectiveness of a standard conservative treatment of alveolitis sicca – a painful complication of an extraction wound healing to the treatment thereof with bio-stimulating laser. Methods: In our study, the patients with alveolitis sicca were offered to choose between a standard conservative treatment and a bio-stimulating laser treatment. The patients in the first group (49 persons), who were diagnosed with alveolitis sicca in our dental office, were treated by a standard conservative treatment – daily exchange of a drain with antiseptic and benzocain. If due to pain the drain had to be exchanged more often than every 24 hours, this was considered as an unsatisfactory therapeutic effect. The patients in the second group (21 persons) were daily treated with bio-stimulating laser radiation of the wound with a modulated ray of the frequency of 2,28 Hz at the infra-red end of the spectrum (830 nm). During each session we applied 2 J/cm2. Thereafter we introduced a gauze drain dipped in saline into the socket. If a satisfactory relief of pain was not obtained and a patient demanded different type of a treatment, this was considered as an unsatisfactory therapeutic effect of Results: It has been statistically confirmed that a standard conservative treatment of alveolitis sicca had significantly better analgesic effect in the observed groups when compared to

        Key words: alveolitis sicca – low level laser therapy – tamponage of the socket – period of healing – analgesic effect
