摘要
Purpose: The major concern of sagittal split osteotomy (SSO) is the neurosensory disturbance. The authors investigated the effect of low-level laser therapy and light-emitting diode on the inferior alveolar nerve recovery after SSO. Methods: In this double-blinded randomized clinical trial, 20 subjects with inferior alveolar nerve injury after SSO of the mandible were studied. Neurosensory recovery was assessed by 6 tests: visual analog scale (VAS), brush stroke, 2-point discrimination, contact detect detection, pinprick nociception, and thermal discrimination, and each one was performed before and after the surgery on days 1, 3, 7, 14, 60, and 180. Results: After 1 week, the VAS score in the laser group significantly improved in comparison with the control group. Visual analog scale score improvement was 25% (P = 0.015) at 2 weeks, 21% (P = 0.001) at 2 months, and 24% (P = 0.001) at 6 months. After 2 weeks, the brush stroke score improvement was significant in the laser group. The improvement values were 21.5% (P = 0.002) at 2 months and 15.1% (P = 0.004) at 6 months. Conclusion: Low-level laser therapy and light-emitting diode may improve VAS scores, 2-point discrimination, and brush stroke test results without any effect on the pinprick or contact detection test results.
