Abstract: Objective: To compare the difficulty and complications of the extraction of impacted mandibular third molar germs and impacted mandibular third molar. Methods: 41 patients with impacted mandibular third molar germs (Group A) and 40 patients with impacted mandibular third molar (Group B) were randomly selected. Parameters evaluated included the mean operation time, pain response, local swelling, and mouth opening change after tooth extraction. Results: Compared with Group B, the mean operation time of Group A was shorter. Moreover, pain response, local swelling and opening degree change of Group A were less severe. Conclusion: Extraction of the impacted mandibular third molar germs is simple and yielded less resultant complications.

Key words: Impacted mandibular third molar germs, Impacted mandibular third molar, Tooth extraction
