研究目的: |
阻生下颌第三磨牙拔除导致邻近第二磨牙牙周组织破坏是临床治疗面临的一大难题。第三磨牙拔除术中切口设计是第一步,且有研究表明,不同切口设计对牙周组织的影响有差异。 为了尽量减少阻生下颌第三磨牙拔除对邻近第二磨牙牙周组织的影响,本研究通过设计不同的切口,比较在第三磨牙拔除后邻牙牙周组织及龈下菌群的变化,为第三磨牙拔除提供新的思路。 |

|
Objectives of Study: |
The extraction of impacted mandibular third molars leads to the destruction of the periodontal tissue adjacent to the second molars, which is a major problem in clinical treatment. Incision design is the first step in third molar extraction, and studies have shown that different incision designs have different effects on periodontal tissue. In order to minimize the impact of the extraction of the impacted mandibular third molar on the periodontal tissue of the adjacent second molar, this study designed different incisions to compare the changes in the periodontal tissue and subgingival flora of the adjacent teeth after the extraction of the third molar. Third molar extraction provides new ideas. |
