Abstract:
Objective:The present study evaluated postoperative reactions in adjacent teeth after the extraction of lower-level horizontal-impacted mandibular third molars using a T-shaped splitting method.
Methods:A total of 101 patients with lower-level horizontal impaction of mandibular third molars were selected and randomly divided into two groups. The impacted mandibular third molar was extracted using a T-shaped splitting method in group A （56 cases）, and the traditional two-section method was used in group B （45 cases）。 Postoperative reactions, including temperature sensitivity, percussion pain and mobility in the adjacent teeth, were compared between the 2 groups at 1-week, 2-week, and 1-month follow-up visits. The SPSS 13.0 software package was used for the statistical analysis.
Results :The postoperative reactions of temperature sensitivity （χ21w= 11.81, χ22w = 17.43, P < 0.05）, percussion pain （χ21w = 8.70, χ22w = 4.75, P < 0.05） and mobility （χ21w = 4.50, χ22w = 7.10, P < 0.05） in adjacent teeth in group A were significantly less than those in group B at the 1-week and 2-week follow-up visits. The temperature sensitivity in adjacent teeth in group A was significantly less than that in group B at the 1-month follow-up visit （χ2 = 7.10, P < 0.05）, but percussion pain and mobility in adjacent teeth disappeared in both groups.
Conclusion:The T-shaped splitting method for the extraction of mandibular lower-level horizontal impacted third molars can reduce the postoperative reactions in adjacent teeth.
