Abstract: Pain management is a key factor in success of any dentist. Inferior alveolar nerve block is one of the most commonly used techniques to obtain mandibular anaesthesia. Due to importance of theoretical and practical training during the course of study, the aim of this study was to evaluate the success rate of standard inferior alveolar nerve block technique performed by the fifth and sixth year students. This cross sectional study was performed on 29 sixth year and 32 fifth year dental students. Patients needed tooth extraction or dentoalveolar surgery in mandible, were randomly distributed between the students. The students performed standard inferior alveolar nerve block and after 5 and 10 minutes, numbness of the corner of the lip, floor of the mouth and buccal mucosa was tested by pin prick test with a dental explorer. Data were analyzed by SPSS software version 18.0 and chi-square test was used for statistical analysis and p<0.05 was considered statistically significant.Only in achieving numbness of the corner of the lip after 5 minutes, there was significant difference between males and females (p<0.05). The mean success rate of sixth and fifth year students was 76.2 ± 7.2% and 55.5 ± 13.1%, respectively. The success rate of sixth year students was significantly higher than fifth year ones (p < 0.05). In conclusion, Experience and the skill of the operator play a critical role in success of the inferior alveolar nerve block injection.
