Surgical extraction of retained lower third molars is associated with the development of postoperative complications, including inflammation, trismus and postoperative pain. Traditionally, NSAIDs have been used for the treatment of postoperative pain and inflammation, although corticosteroids are increasingly used in oral surgery, as they have proven to be clinically effective in reducing postoperative complications without causing serious adverse effects. Although numerous studies have been carried out comparing different corticosteroids in order to determine which of them is the most effective, there is still no clinical protocol regulating the use of these drugs in oral surgery. Therefore, this clinical trial is based on comparing two of the most studied corticosteroids used in oral surgery to date: dexamethasone and methylprednisolone.~This study is based on the preoperative administration of 8mg of dexamethasone or 40mg of methylprednisolone via submucosa, randomly, in patients undergoing surgical extraction of a retained lower third molar, to determine which of these two drugs is more effective in the prevention of inflammation, trismus and postoperative pain.
Surgical extraction of retained lower third molars is associated with the development of postoperative complications, including inflammation, trismus and postoperative pain, that lead to a decrease in patients' quality of life. Therefore, the use of drugs is essential to reduce the morbidity associated with surgery, with NSAIDs and corticosteroids being the most commonly used drugs.
