The comparison of pain, stress and vital signs in patients while extracting teeth with and without Nitrous Oxide (N2O) and Oxygen (O2)

摘要

Pain has long been among the human's main problems and effective steps have been taken towards relieving it. Toothache is among the hardest pain to endure and everyone is likely to experience it in his lifetime. Severe toothache brings about stress responses and has harmful effects on the patient involved. Considering the bad effects of the pain, the present study aims at finding the efficacy of using Nitrous Oxide and Oxygen (N2o-O2) in extracting teeth and making this a common method in Iran. In the present study as many as 20 patients were chosen who had some teeth to be extracted following their referrals to Tabriz Faculty of Dentistry. The patients were divided into two groups. All the facilities and requirements necessary were equal for both groups and some teeth were extracted using the common methods of local anesthesia and some teeth were extracted using Nitrous Oxide. The average results obtained indicate that, in comparison with local anesthesia, using Nitrous Oxide causes to relieve stress, pain, and other vital signs including blood pressure (either before or after the operation) and the number pf pulses among the patients studied. However, statistically speaking the difference was not significant. According to the findings of the present study, in comparison with local anesthesia, Nitrous Oxide is more effective in relieving the pain and thus it is more effective in controlling pain, stress, and other vital signs.
