This study evaluated trismus and pain after removal of impacted lower third molars and investigated whether these responses were related to difficulty of surgery. ⋯ Trismus is less severe after simple (forceps-only, grade I) extractions than after surgical extractions (grades II to IV). However, trismus severity after surgical extraction does not depend on difficulty of surgery. Pain, as revealed by reported analgesic use, is likewise less severe after simple extractions. Regardless of extraction type, pain declines between days 1 and 5 postsurgery.

Randomized Controlled Trial Clinical TrialAmnestic and anxiolytic effects of alprazolam in oral surgery patients.
This study was designed to identify a dose of alprazolam that would reduce anxiety associated with oral surgery without causing accompanying memory impairment. ⋯ These findings indicate that alprazolam produces memory impairment at the dosages necessary to produce clinically significant anxiolysis during oral surgery.

Randomized Controlled Trial Comparative Study Clinical TrialCapnography and ventilatory assessment during ambulatory dentoalveolar surgery.
The purpose of this study was to determine whether capnography is a more sensitive monitor than auscultation of breath sounds in detecting ventilatory changes consistent with hypoventilation, obstruction, or apnea and in detecting ventilatory changes that can be associated with oxygen desaturation. ⋯ Patients with nasal ventilatory exchange maintain this exchange throughout the anesthesia so that sampling of nasal PETCO2 is an effective way to monitor ventilatory status. Respiratory depression or obstructive ventilatory changes detected by capnography showed a high sensitivity and low positive predictive value in detecting oxygen desaturation. The current technology does not show a clinically satisfactory correlation between PETCO2 and oxygen saturation. However, a combined increase in PETCO2 and decrease in RR suggested a trend of decreasing oxygen saturation.
