The effects of a single high-dose injection of vitamin-D on healing of condylar fractures in osteoporotic rats

Abstract

Aim: In this study we have tried to show the effects of a singlehigh-dose ınjection of vitamin d on healing of condylar fractures in osteoporotic rats.Materials and method: This study included sixteen femalewistar rats. All rats were overiectomized. Osteoporotic ratswere randomly divided into two groups of eight animals/group. Group D animals received a single high dose of vitamin D (50.000 IU/kg) intraperitoneally and group C (control)animals received saline (0.05 mL) intraperitoneally. All injections were given immediately after condylar fracture. All ratswere euthanized after 28 days, examined histopathologicaland immunohistochemical.Results: Histopathological and immunohistochemical evaluations were done. Histopathological scores between groupD and C were found statistically significant. TGFβ1 and osteopentin levels in group D were found higher than group C.Conclusion: We have determined that a single high-dose injection of vitamin D given immediately after surgery increasedTGFβ and osteopontin levels and enhanced new bone formation at condylar fractures of osteoporotic rats.
