Abstract
BackgroundThe aims of this study were: 1) compare the amount of anesthesia used with the anesthetic technique; 2) relate the quantity of anesthesia needed with the level of anxiety of the patient; 3) study the relationship between the anesthetic technique and the level of hemostasis; 4) correlate the amount of anesthesia with patient and tooth dependent variables. Material and MethodsA randomized controlled trial was designed with two parallel groups according to the anesthetic technique: infiltrative local anesthesia (infiltrative group) and inferior alveolar nerve block (block group). The following variables were collected: sex, age, smoking habits, plaque index, symptoms, signs, position of the tooth and amount of anesthesia. Before surgery, all patients were asked to assess their anxiety on a six-item questionnaire, the Amsterdam Preoperative Anxiety and Information Scale (APAIS). The analysis of the hemorrhage control of aluminum chloride was judged by the surgeon and two examiners independently and recorded it as: 0 (no hemorrhage control), 1 (slight but apparent intermittent bleeding persisted after application of the material), or 2 (complete hemorrhage control). ResultsTwenty patients were included in this preliminary report. The amount of anesthesia used was lower in block group and in less anxious patients, although these results did not reach statistical significance. A relationship was found between the quantity of anesthesia used and a good hemostasis of the bony crypt before the application of the hemostatic agent (p<.05); and between elderly patients and a lower amount of anesthetic reinforcement (p<.05). ConclusionsBased on these preliminary results, we can conclude that no statistical significance difference was found between the amount of anesthesia used and the anesthetic technique or the anxiety. A relationship was found between hemostasis of the bony crypt and the quantity of anesthesia used; and between younger patients and a greater amount of anesthetic reinforcement. Key words:Anesthesia, anxiety, endodontic surgery, hemostasis, hemostatic agents,periradicular surgery.

The generation of effective intra-operative anesthesia and hemostasis are critical pillars supporting the foundation of effective periapical surgery procedures [1]
The aims of this study were: 1) compare the amount of anesthesia used with the anesthetic technique; 2) relate the quantity of anesthesia needed with the level of anxiety of the patient; 3) study the relationship between the anesthetic technique and the amount of anesthesia with the level of hemostasis; 4) correlate the amount of anesthesia with patient and tooth dependent variables
When the concern for anesthesia was “not at all” or “slightly”, 50% of the patients did not need more than 1.8mL of anesthetic reinforcement; and when the concern was “moderately” or “very”, 50% of the patients needed more than 2.7mL of anesthetic reinforcement
