Aim: To stress the importance of surgical planning when treating large dentigerous cysts.

Case Report: In a routine radiographic examination, a dentigerous cyst was revealed in a 20 years old male. A surgical approach that ensured the integrity of the inferior alveolar nerve (IAN) was applied. The incision was exceeded to the mesial surface of the first molar in order to create adequate surgical field and visibility. The final result was that the exposed nerve was protected successfully.

Conclusion: This case shows the necessity of a meticulous preparation, even in routine operations.
