The effect of 4 mg dexamethasone after surgical removal of lower third molar
Abstract:
Dexamethasone, one of corticosteroids, possesses an anti-inflammatory effects that can be used to reduce inflammation in many situations. Sequelae after removal of impacted third molar is also a major concern in patients which may lead to delay or ignorance of treatment, especially in the case that treatment is required. Dexamethasone has been proposing as adjuvant therapy to prevent the inflammatory complication following third molar surgery using various dosages and routes. To keep away from systemic adverse effects of steroid avoid, low dose dexamethasone that can provide a sufficient anti-inflammation is desired. This study aimed to evaluate the effect of preoperative 4 mg dexamethasone submucosal injection after lower third molar surgery.
A randomized control, triple blinded, in splint mouth design study was carried out in
discipline of Oral Surgery, Rangsit University. Participants with bilateral identical lower third molar impaction were enrolled in this study. Those fulfill criteria and consented were randomly allocated to group and side of surgery. Dexamethasone 4mg/ml or normal saline solution was injected submucosally before operation. Wash-out period was set at 4weeks-time. Participants were operated by a single surgeon and only one assessor were arranged. Swelling measured by facial contour and percentage swelling, maximal mouth opening were assessed on post-operative day (POD)1, 3 and 7.
Seventeen participations, 3 males and 14 females, average aged at 21.94years were recruited in the study. Dexamethasone demonstrated a significant reduction in pain on POD1, 2, 3, and 7 as compared to control, p<0.05. Swelling and maximal mouth opening revealed comparable in both groups on POD1, 3 and 7, p>0.05. However, less swelling by time was detected in dexamethasone group. For the quality of life, dexamethasone showed a significantly less affect than control, especially in physical aspect ( p < 0.05).
Preoperative submucosal injection of 4mg Dexamethasone provides pain reduction, improve
quality of life and tended to reduce facial swelling after surgical removal of lower third molar.
