Abstract:
The aim of this study was to evaluate postoperative pain in patients who had a single tooth or multiple erupted teeth extracted. This research evaluated 520 consecutive dental extraction surgeries in which 680 teeth were removed. Data collection was obtained through a questionnaire of patients and of the undergraduate students who performed all procedures. Pain was evaluated through qualitative self-reported scores at seven days postsurgery. An increased pain level was statistically associated with ostectomy, postoperative complications, and tobacco consumption. Pain that persisted for more than two days was statistically associated with the amount of anesthetic solution used, with a notable increase in surgical time and development of postoperative complications. Periods of pain lasting more than two days could be expected for traumatic surgeries lasting more than 30 minutes. Both severe and prolonged pain were signs of development of postoperative complications, such as alveolar osteitis and alveolar infection.
