摘　　要：目的:评估年轻人无症状的完全埋伏阻生上颌第三磨牙采用微创拔除后12个月内上颌第二磨牙远端牙周状况的变化。方法:本研究抽取43个高危牙周风险的阻生上颌第三磨牙。在术前和术后3、6和12个月随访,记录邻近第二磨牙远端5个位点的菌斑指数、牙龈指数、探诊深度(PD)。结果:初始PD为(3.67±1.64)mm,最深的平均PD在远中腭侧线角。12个月时,PD平均值为(2.12±0.70)mm,平均恢复高度为(1.55±1.47)mm(P<0.05),3个月时较高为(1.46±1.45)mm(P<0.05)。并且从术前到术后12个月上颌第二磨牙远端的5个位点PD的改善均具有统计学意义(P<0.05)。术后12个月上颌第二磨牙的菌斑指数和牙龈指数均改善。结论:无症状的完全阻生上颌第三磨牙可导致邻近第二磨牙牙周缺损,在远中腭侧线角最深,拔除后12个月5个位点均不同程度恢复。前3个月被认为是牙周愈合的重要时期。有高危牙周风险上颌第三磨牙的年轻人可以从早期拔牙中获益。Objective:To evaluate the change in the periodontal status of maxillary second molars after minimally invasive surgical extraction of asymptomatic adjacent impacted lower third molars.Methods:This prospective clinical study was conducted in 43 higher-risk periodontal impacted maxillary third molar.Plaque index,gingival index,and bleeding on probing and probing depth(PD)were recorded before surgery and at 3,6,and 12 months after surgery at 5 sites on the distal aspect of the maxillary second molars.Results:The initial mean PD was(3.67±1.64)mm,with the deepest mean PD was at the distopalatal of the distal surface.At 12 months,a mean PD average of(2.12±0.70)mm was recorded,with a total average recovery of(1.55±1.47)mm(P<0.05),that was higher at 3 months(1.46±1.45)mm(P<0.05).The improvements of PD were statistically significant(P<0.05)from baseline to 12-month follow-up and from the buccal to the distopalatal of the distal aspect of the maxillary second molars.The plaque index and gingival index of maxillary second molars were improved 12 months after surgery compared with those before surgery.Conclusion:Young adults with high-risk periodontal maxillary third molar impactions may benefit from early extraction.
