Insomnia and Post-Dental Surgery Pain: A Prospective Study

The purpose of this prospective observational study is to evaluate the relationship between preoperative sleep disturbances-specifically insomnia-and postoperative pain intensity following oral surgical procedures. Recent scientific literature highlights a bidirectional relationship between sleep disorders and pain in dentistry, suggesting that disturbed sleep may actively exacerbate subsequent pain perception. Although postoperative pain, swelling, and masticatory difficulties are common after dental extractions, clinical data investigating the direct impact of preoperative sleep quality on these surgical outcomes remain scarce. This study will enroll adult patients undergoing routine dental extractions and allocate them into two cohorts based on their baseline sleep quality: patients without preoperative sleep disturbances and patients with preoperative sleep disturbances. Pain levels and sleep parameters will be assessed using validated questionnaires before the surgery and at a 7-day follow-up. The primary objective is to determine whether the presence of preoperative insomnia leads to a significant increase in perceived postoperative surgical pain.
