Comparing the Effect of Hypnosis and Local Anesthesia Injection on Induction of Local Anesthesia, Anxiety, Hemorrhage and Pain Control during Tooth Extraction

There are cases in dentistry that despite the injection of local anesthesia, the desired numbness for tooth extraction can't be achieved or the use of common local anesthetic is contraindicated for the patient. Therefore, in these cases a complementary treatment can be introduced. The aim of this paper is to compare the effect of hypnosis and local anesthesia injection on induction of local anesthesia, anxiety, hemorrhage and pain control during tooth extraction. This randomized cross over trial research is carried out with 16 patients, with a mean age of 22 years and symmetric erupted third molars who were referred to the department of oral and maxillofacial surgery in Faculty of Dentistry of Rafsanjan University. For each patient the third molars on one side were extracted under hypnosis or local anesthesia and after a week on the opposite side under the other method. The Spielberger State Trait Anxiety Inventory was used to determine patients' anxiety level before and after hypnosis and injection. Pain was scored using VAS (Visual Analogue Scale) to measure hemorrhage volume. After surgery the patient was asked to bite a sterile gauze pad over the surgical site for 3o minutes and if the bleeding was more than slight ooze at, 12, 24 and 48 hours post operatively, they were supposed to mark it on the list. Data was analyzed using SPSS 19 statistical software. When local anesthesia was chosen the number of anesthesia cartilages used, anxiety level and pain intensity at 5 and 12 hours post operatively were higher than the time hypnosis was selected. (p<0.050). However, the maximum pain intensity during tooth extraction was much less when done under hypnosis rather than local anesthesia. (p<0.001).there was no significant difference between the two methods in terms of pain intensity and hemorrhage in 24 and 48 hours post operatively. (p>0.050). At clinical aspect, it seems the success of hypnosis in induction of anesthesia was less than injection and as mentioned above there was no significant difference between the two methods in terms of hemorrhage in 24 and 48 hours post operatively. The result of the study indicated that hypnosis can reduce anxiety and postoperatively pain.
