abstract = {ObjectiveThe 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.MethodsA 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.ResultsThe postoperative reactions of temperature sensitivity (χ1w2= 11.81，χ2w2 = 17.43，P < 0.05)，percussion pain (χ1w2 = 8.70，χ2w2 = 4.75，P < 0.05)and mobility (χ1w2 = 4.50，χ2w2 = 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.ConclusionThe T-shaped splitting method for the extraction of mandibular lower-level horizontal impacted third molars can reduce the postoperative reactions in adjacent teeth.}
