Comparative Study
Comparison of efficiency of hyaluronic acid and/or bone grafts in healing of bone defects.
Reconstruction of bone defects in oral and maxillofacial surgery has widespread uses. In recent years, the capacity of various biomaterials alone or in combination with bone graft materials to increase bone healing has been an intensive research topic. The aim of this study is to evaluate the efficacy of hyaluronic acid and/or bone graft material on bone healing in defects created in the rat mandible. Methods: In our study, rats were divided into 4 groups. Group 1 is designated to be treated with no materials, Group 2 with graft material, Group 3 with only hyaluronic acid, and Group with hyaluronic acid and graft material. A critical-size defect of 5 mm in diameter was created bilaterally in the rat mandibles and the rats were divided into the indicated groups accordingly. At the end of the postoperative 6th week, the experiment was terminated. The right halves of the mandibles were evaluated immunohistochemically and histopathologically in terms of bone healing, and the left in terms of mineralization level via microcomputed tomography. ⋯ In conclusion, the use of hyaluronic acid alone or in combination with bone grafting has been shown to contribute positively to the improvement of bone defects in the jaw area.

Studies related to traditional practices and benefits have been usually performed among women. The literature regarding the traditional practices used by men in Turkey and around the world and their expected benefits is more limited. The aim of this study was to examine the traditional practices used by couples with fertility problems, affecting factors, expected benefits, and learning paths. ⋯ The couples in this study widely used traditional practices to solve fertility problems and learned from their friends and partners.
