摘　　要：目的探讨下颌第三磨牙前倾阻生与颞下颌关节滑膜炎的关系。方法40例牙列完整、双侧下颌第三磨牙前倾阻生(倾斜角为30~60°)、临床诊断为颞下颌关节滑膜炎的患者,随机分为A组和B组,每组20例。A组行下颌第三磨牙前倾阻生齿拔除术,B组拔除前倾阻生的下颌第三磨牙并于次日开始行口颌系统功能锻炼。比较两组治疗效果、视觉模拟评分法(VAS)评分、治疗前后下颌第一、二磨牙所占应力百分比及应力百分比变化差值。结果B组治疗后有效率100.00%高于A组的70.00%,差异有统计学意义(P<0.05)。治疗后,两组VAS评分均较治疗前降低,且B组VAS评分(0.91±0.93)分低于A组的(1.58±1.09)分,差异有统计学意义(P<0.05)。治疗后,A组和B组下颌第一磨牙所占应力百分比(15.23±2.67)%、(14.92±3.13)%较本组治疗前的(13.05±2.98)%、(12.35±4.41)%升高,第二磨牙所占应力百分比(19.65±2.48)%、(18.90±3.31)%较本组治疗前的(24.60±3.44)%、(29.35±4.29)%降低,差异均具有统计学意义(P<0.05)。两组治疗前后下颌第一磨牙应力百分比变化差值比较,差异无统计学意义(P>0.05);B组治疗前后下颌第二磨牙应力百分比变化差值-(10.45±2.24)%与A组的-(4.20±3.83)%比较差异有统计学意义(P<0.05)。结论拔除下颌前倾阻生的第三磨牙后行口颌系统功能锻炼较单独拔除下颌前倾阻生的第三磨牙治疗颞下颌关节滑膜炎的效果显著。Objective To discuss the correlation between mesioangular impaction of the mandibular third molars and temporomandibular joint synovitis.Methods A total of 40 patients with complete dentition,bilateral mesioangular impaction of the mandibular third molars(inclination angle of 30~60°)and clinically diagnosed as temporomandibular synovitis were randomly divided into group A and group B,with 20 cases in each group.Group A underwent extraction of mesioangular impaction of the mandibular third molars,group B underwent extraction of mesioangular impaction of the mandibular third molars and oral and jaw system functional exercises the next day.The therapeutic effect,visual analogue scale(VAS)score,stress percentage and the difference of stress percentage of the mandibular first and second molars before and after treatment were compared between the two groups.Results The effective rate after treatment 100.00%of group B was higher than 70.00%of group A,and the difference was statistically significant(P<0.05).After treatment,VAS score of the two groups were lower than those before treatment,and VAS score(0.91±0.93)points of group B was lower than(1.58±1.09)points of group A,and the difference was statistically significant(P<0.05).After treatment,the stress percentage of mandibular first molar of the two groups were(15.23±2.67)%and(14.92±3.13)%,which were higher than(13.05±2.98)%and(12.35±4.41)%before treatment;the stress percentage of mandibular second molar of the two groups were(19.65±2.48)%and(18.90±3.31)%,which were lower than(24.60±3.44)%and(29.35±4.29)%before treatment,and the difference was statistically significant(P<0.05).There was no statistically significant difference in the difference of stress percentage of mandibular first molar before and after treatment between the two groups(P>0.05).The difference in the stress percentage of the mandibular first molar before and after treatment of group B was-(10.45±2.24)%,which was greater than-(4.20±3.83)%of group A,and the difference was statistically sign
