Effects of Low-Level Laser Therapy With a Herbal Extract on Alveolar Bone Healing.
Journal of Oral and Maxillofacial Surgery 2018 Februrary
PURPOSE: This study investigated the effect of a gallium-aluminum-arsenide (GaAlAs) diode laser used in low-level laser therapy (LLLT) with the application of Mecsina Hemostopper on mandibular alveolar bone healing.
MATERIALS AND METHODS: Standard semispherical bone defects were created in left mandibular diastema sites of 32 female Long-Evans rats. Experimental animals were allocated to 1 of 4 groups: control group (no treatment), laser group (GaAlAs LLLT), Mecsina group, and laser-Mecsina combination group. Liquid Mecsina 0.01 mL was applied to the bone defects. Laser treatment was performed for 7 days after surgery at an energy dose of 10 J/cm2 . All animals were sacrificed to observe hard tissue healing histologically, immunohistochemically, and radiologically at 30 days after surgery.
RESULTS: Histologic assessment showed significantly more calcified tissue areas and significantly more osteoblast cells in the laser and laser-Mecsina groups than in the other groups (P < .01). Qualitative morphologic assessment showed that more bone tissue was present in the laser-Mecsina group than in the other groups.
CONCLUSION: This study showed that LLLT, Mecsina application, and combined treatments were effective in healing alveolar bone among all tested treatment modalities.
