Abstract
Background and Purpose: Third molar surgery is one of the most common operations performed worldwide. Pain and trismus following third molar surgery is common and may reduce quality of life. The purpose of the current study was to investigate the therapeutic effect of Low level laser therapy and Microcurrent therapy in reducing pain and trismus after third molar surgery. Assessment was done pre treatment, after 5 sessions and post treatment using visual analogue scale and vernier caliper gauge. Methods: Thirty patients with third molar removal surgery participated in this study and their ages ranged between 20-40years. The patients were randomly assigned into two equal groups (15 patients for each group): laser group (A) and microcurrent group (B).Results: There was significant improvement in range of mouth penning (ROM) degree in group (A) compared to group (B).Conclusion: The study concluded that application of low level laser can be more effective in reducing trismus than Microcurrent Therapy after third molar surgery
