Abstract

Introduction
The importance of clinically adequate pain control during dental treatment is highlighted by the fact that it is not possible to safely complete treatment in absence of local anesthetic techniques. In case of any improper technique (method of injection, site of injection, time length of injection etc.) Unpredictable and adverse effects will show up. The purpose of this study was to determine the time length of local anesthetic injection in inferior alveolar nerve block.
Materials & Methods  
1200 local anesthetic injections (1/8 ml lidocaine+ epinephrine; made by daroopakhsh Co.) by direct technique for mandibular  nerve block (400 injection for each surgeon) by three oral and maxillofacial surgeons were done and time lengths of  injections were recorded . Data were analyzed using SPSS software.
Results:
The average time of local anesthetic injection was 32 seconds.
Conclusion
Our findings are significantly different (p<0.05) from accepted standard mean which is 60 seconds (P<0.05). Thus, The chance of developing side-effects and complications due to injection is probable to increase.
