[Evaluation of the effect of cruciform tooth division and T-type crown amputation in extraction of mandibular middle and low impacted teeth].
Purpose: To evaluation the effect of cruciform tooth division and T-type crown amputation in extraction of mandibular middle and low impacted teeth.
Methods: A total of 81 patients with mandibular middle and low impacted teeth treated in Bozhou People's Hospital from September to November 2024 were selected. According to the different extraction methods,they were divided into the control group(n=40, T-type crown amputation) and experimental group(n=41, cross tooth extraction). The operative time, intraoperative complications(anxiety, broken root), postoperative complications (pain, swelling and restricted mouth opening), healing of tooth extraction socket 1 week after surgery, and quality of life before and 1 week after surgery[oral health impact scale 14(OHIP-14)] were compared between the two groups.
Results: The operative time of the experimental group was significantly shorter than that of the control group, the total incidence of intraoperative complications(4.88%) was significantly lower than that of the control group (20.00%), the score of postoperative pain and mouth opening restriction was significantly lower than that of the control group, the degree of postoperative swelling was significantly less than that of the control group, and the total incidence of postoperative complications(4.88%) was significantly lower than that of the control group(32.43%). The healing score of tooth socket 1 week after operation was significantly lower than that of the control group (P＜0.05). One week after surgery,the OHIP-14 score of both groups was decreased,and the experimental group was significantly lower than the control group(P＜0.05).
Conclusions: Compared with T-type crown amputation, cruciform tooth division can shorten the operation time of mandibular middle and low impacted tooth extraction, reduce the occurrence of intraoperative anxiety, broken root, postoperative pain, swelling and restricted mouth opening, and is conducive to the healing of tooth extraction wound.
