【Abstract】 Objective To detect the validity of extracting tooth in the presence of acute pericoronitis. Methods Extraction of the impacted mandibular third molar was conducted at the early stage of acute pericoronitis, compared with the conservative treatment of pericoronal pocket rinse. The relieving cases in 48 h and the relieving period were recorded. Results In 296 cases of acute pericoronitis treated by extracting the impacted third molar, 87.16% relieved completely in 48 h and the relieving period was 1.6 d. In 62 cases treated conservatively, 19.35% relieved completely in 48 h and the relieving period was 3.8 d. Conclusion At the early stage of acute pericoronitis, extracting the impacted third molar may be an effective choice.更多还原
