RESUMO
Background and Objectives: Inferior alveolar nerve block [IANB] is commonly applied for anesthesia of lower jaw but because of its anatomical location. The success rate of IANB is low. According to the fact that most of patients have radiography when refer to the dentists, we compared the success rate of anesthesia with or without using radiography to make IANB
Materials and Methods: In this study the patients referred to the maxillofacial department of Tabriz faculty of dessistry between 2011-2012 were included. At the first stage IANB was performed without using radiography and at the second stage we used radiography. Finally the success rate of this two methods were compared
Results: Thirty one [12 female -19 male] patients with mean age of 37.16 +/- 10.47 were included in this study. We found statistically significant difference between the success rate of this two methods [p=0.02]
Conclusion: Using radiography significantly success rate of IANB injection
