Assessment criteria for the healing process of periodontal diseases

近年来，牙周病的研究取得了重大进展。其中，利用人工骨填充牙槽骨缺损、骨诱导材料（骨形态发生蛋白）的应用以及引导组织再生技术的引入被认为是牙周病治疗的重大突破。虽然我们在每个治疗过程中都有标准，但评估整个治疗过程的标准尚未建立。本研究的目的是通过对牙齿活动度的研究、牙周袋内细菌的监测以及患者对治疗后牙周状况的满意度调查，建立评估牙周疾病整体治疗效果的标准。结果如下：(1)牙活动度：采用镊子、牙周计和牙周计三种方法测定牙活动度。3种方法之间存在较强的相关性。我们未发现3种方法与Perotron测量的GCF量之间存在显著相关性。我们观察到三种方法与牙槽骨的数量呈正相关。(2)牙周袋内细菌形态：采用DNA探针法研究牙周袋内细菌形态的变化。青少年牙周炎与a.a的优势之间的显著关系已被报道。据推测，青少年牙周炎患者口腔中的A.a.可能来自其母亲的口腔。(3)患者心理自我评价：向患者和牙科工作人员（牙科学生、口腔卫生员和牙医）发放牙周状况自我评价标准问卷。患者与牙科人员对牙周状况的估计存在相当大的差异。结论：牙周手术后患者与牙周护理人员对牙周功能的评价存在差异。少

Recent researches in periodontics have accomplished significant development. Among them, the use of artificial bone to fill the alveolar bone defects, the applicaton of osteoinductive material (Bone Morphogenetic Protein) and the introduction of the guided tissue regeneration technique are considered as the major breakthroughs in the treatment of periodontal diseases. Although we already have criteria in each treatment procedure, the criteria to assess the entire treatment procedures, have not been established.The purpose of this research is to establish the criteria for asessing the entire treatment of perodontal diseases through the studies of tooth mobility, monitoring of the bacteria in the periodontal pockets and the investigation of patient's satisfaction level in the outlook of the periodontal condition after the treatment.The results obtained were as follows :(1) Tooth mobility : Three methods (Tweezers, Periotest and Periocheck) were used to determine the tooth mobility. Posit … More ive correlation existed among the 3 methods. We had not detected the significant correlation between the 3 methods and the amount of the GCF measured by the Perotron. We observed positive correlation between each of the 3 methods and the amount of the alveolar bone.(2) Bacterial configuration pattern in the periodontal pocket : Change of bacterial configuration pattern in the periodontal pocket has been investigated using the DNA probe method. Significant relationship between the juvenile periodontitis and the predominance of the A.a. has been notified. It has been speculated that the A.a. in the mouth of the jevenile periodontitis patients may come from their mother's mouth.(3) Psychological self-setimation in patients : Questionaires related to the criteria for the self-aasessment of the periodontal condition, were presented both to the patients and to hte dental personnel (dental students, oral hygienists and dentists). Considerbale difference in the estimation of periodontal condition existed between the patients and the dental personnel. It was concluded that the evaluation of the gingival resession differs between the patients and dental personnel concerning about the periodontal condition after the periodontal operation. Less
