296件树脂暂时冠导致牙龈炎的原因分析及应对措施

The reason and preventive measure analysis of gingivitis caused by resin temporary crowns from 296 cases

目的:分析树脂暂时冠戴冠后并发牙龈炎的原因,探讨减少牙龈炎、保护牙周组织的措施。方法:选择患者183例,共296件树脂暂时冠,戴冠1周后。对患者进行牙周状况和修复体的检查。结果:有68件树脂暂时冠发生牙龈炎症,其中修复体边缘不合要求者24件,占35.2%;粘接材料龈沟内残留者15件,占22.1%;邻接关系不良者15件,占22.1%;修复体外形不合要求者11件,占16.2%;差异均具有统计学意义(P<0.01);另有暂时冠局部无明显异常者3件,占4.4%。结论:暂时冠边缘不合要求、粘接材料龈沟内残留、邻接关系不良、修复体外形不合要求是导致牙龈炎症的主要原因,对暂时冠材料过敏也可能是原因之一。预防牙龈炎症,暂时冠制作时应注意修复体边缘及外形、修复体与邻牙的邻接关系,粘接完成后应尽量去除残留于龈沟内的粘接材料。

Objective： To discuss the reasons of gingivitis after wearing resin temporary crown and to reduce gingivitis and protect periodontal tissue. Method： 183 patients were included with 296 cases of resin temporary crown. After wearing a crown for 1 week,periodontal status and restoration of patients were inspected. Result： 68 cases of resin temporary crown happened gum inflammation.The cases of repair edge undesirable were 24, accounting for 35.2 %;The cases of bonding material of gingival groove residual were 15, accounting for 22.1%;The cases of bad abjacency relations were 15, accounting for 22.1%：The cases restoration of undesirable appearances were 11, accounting for 16.2 %.Both the statistics was difference （P 〈0.01） .Another 3 cases of dental crown did not see obvious anomaly, accounting for 4.4 %. Conclusion：Temporary crown edge out requirements, bonding material gingival groove residue,adjacency relations bad and repair body shape out requirements are the main reasons for the cause gum inflammation. In addition, the temporary crown material allergies may also be one of the reasons. To prevent gum inflammation, it should pay attention to the edge of the restoration and appearance, restoration and adjacent teeth adjacency relations when temporary crown is producted. After completion of adhesive, it should as far as possible to remove the bonding material residual in gingival groove. The allergic to material should also be considered.
