The present study was conducted to evaluate mandibular third molar impaction in Bihar Materials & Methods: This study was conducted on 170 patient reported to department with pain in mandibular third molar. The position and level of the impacted teeth were assessed using the Pell and Gregory classification. Results thus obtained were subjected to statistical analysis. Results: Out of 170 patients, 105 (61.7%) had mandibular third molar impaction. Out of 105 patients, males were 65 and females were 40. Common type of impaction was mesio- angular seen in 62, disto- angular in 14, horizontal in 20 and vertical in 9. The difference was significant (P< 0.05). The level of third molar was level A in in 23%, level B in 68% and level C in 9%. Ramus relationship was class I in 20%, class II in 52% and class III in 28%. The difference was significant (P< 0.05). Conclusion: Authors found that most common type of impaction was mesio- angular and level B and class II was most common level and depth of impaction.
