This study aimed to compare the local anesthetic efficacy of IANB via the conventional and Akinosi techniques in patients presenting to the Maxillofacial Surgery Department of School of Dentistry, Shahid Beheshti University.</p><p style="background-color: rgb(239, 243, 250)"> <strong style="margin: 0px padding: 0px border: 0px"><i style="margin: 0px padding: 0px border: 0px"> Methods: </i></strong>This clinical trial was conducted on 80 candidates for bilateral extraction of mandibular molars. For each patient, local anesthesia was induced by IANB injection, which was done by the conventional technique in one side and by the Akinosi technique in the other side of the mouth. The allocation of technique to side was randomized. Time to anesthesia for the long buccal, lingual and inferior alveolar nerves (IAN), degree of pain during injection and tooth extraction and incidence of positive aspiration in the two techniques were evaluated and analyzed using Wilcoxon Signed Rank and Chi square tests.</p><p style="background-color: rgb(239, 243, 250)"> <strong style="margin: 0px padding: 0px border: 0px"><i style="margin: 0px padding: 0px border: 0px"> Results: </i></strong>The mean time to anesthesia for the IAN was 2.82 minutes in the conventional and 3.05 minutes for the Akinosi technique. These values were 1.47 and 1.55 minutes, respectively for the lingual nerve and 1.43 and 1.56 minutes, respectively for the long buccal nerve. Four patients in the Akinosi technique and 12 patients in the conventional technique had positive aspiration. During anesthetic injection with the Akinosi technique, 72.5% were pain free, 18.8% experienced mild, 5% experienced moderate and 3.8% experienced severe pain. These values in the conventional technique were 51.3%, 27.5%, 11.3% and 10%, respectively.</p><p style="background-color: rgb(239, 243, 250)"> <strong style="margin: 0px padding: 0px border: 0px"><i style="margin: 0px padding: 0px border: 0px"> Conclusion: </i></strong>Considering the lack of a significant difference between the success rate of conventional and Akinosi IANB techniques, Akinosi technique seems to be a suitable alternative to the conventional technique since it is less painful and has lower risk of positive aspiration.</p><hr><p class="MsoNormal" dir="rtl"><span lang="FA" style="font-family: Arial, sans-serif"><!--stripped--> <!--stripped--></span></p> <p class="MsoNormal" style="text-align: left direction: ltr unicode-bidi: embed"><b>Source: </b>Journal of Dental School Shahid Beheshti University of Medical Sciences </p> <p class="MsoNormal" style="text-align: left direction: ltr unicode-bidi: embed"><a href="http://jds.sbmu.ac.ir/browse.php?a_id=1344&sid=1&slc_lang=en" target="_blank"><font color="#0000ff">Full Text</font></a></p> Efficacy, Local anesthesia, Inferior alveolar nerve, Akinosi technique, 0 0 http://idai.ir/browse.php?a_code=A-10-32-2933&slc_lang=fa&sid=1 Hassan Mohajerian 100319475328460013640 100319475328460013640 No Dept. of Oral & Maxillofacial Surgery, Dental School, Shahid Beheshti University of Medical Sciences, Tehran, Iran Amir-Hossein Pakravan amirpakravan@yahoo.com 100319475328460013641 100319475328460013641 Yes Dept. of Oral & Maxillofacial Surgery, Dental School, Mazandaran University of Medical Sciences, Mazandaran, Iran Tahmineh Bamdadian 100319475328460013642 100319475328460013642 No Dept. of Prosthodontics, Dental School, Mazandaran University of Medical Sciences, Mazandaran, Iran Pooneh Bidari 100319475328460013643 100319475328460013643 No
