Abstract
Background and Objectives: Impacted third molars surgeries are common in maxillofacial surgery clinics .Post operation complications like pain, swelling, trismus are common. Most of the patients avoid surgery because of post operative discomfort. Reducing these factors is one of the necessities in dental treatments. Several studies have been conducted in case control methods. In most of these studies, interventional factors have not been controlled properly, so there are differences among results. In order to obtain an exact response in application of corticoesteroids, this study was carried out through a cross over method after controlling interventional factors.
Methods and materials: A clinical trial was conducted as cross over and double blinded method. Thirty eight patients were included in the study. In every patient two third molar teeth from mandible were selected, one as a control tooth. For case group 40 mg methylprednisolone was injected in masseter muscle. All of operations were carried out by one oral surgeon. When the interval of both operations of case and control tooth was more than seven minutes, the patient was excluded from the study. In specification, systemic conditions and required information were prepared, and pain, swelling, trismus were evaluated after 48 hours and also after first week of operation by examination and completing questionnaire by participant assistant of the investigation. The interval of both operations was at least one month. The data were statistically analyzed by SPSS and Wilcoxson test.
Results: There is a meaningful difference between pain, swelling and trismus scales after 48 and one week post operation in both case and control groups:(P<0.05).
Conclusion: Methylprednisolone affects properly on impacted third molar surgery and post operation morbidity.
