Assessment criteria for the healing process of periodontal diseases

近年来，牙周病学的研究取得了重大进展。其中，使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。虽然我们已经在每个治疗过程中有了标准，但评估整个治疗过程的标准还没有建立，本研究的目的是通过对牙齿活动度的研究来建立评估牙周病整个治疗过程的标准。牙周袋内细菌监测及术后患者对牙周状况的满意度调查（1）牙松动度：采用镊子法、Periotest法和Periocheck法测定牙松动度。Posit ...更多信息 3种方法之间存在显著相关性。我们没有检测到三种方法与Perotron测量的GCF量之间的显著相关性。3种方法均与牙槽骨骨量呈正相关。(2)牙周袋内细菌构型模式：采用DNA探针法研究牙周袋内细菌构型模式的变化。青少年牙周炎与A.a.已经通知了据推测，A.A.牙周炎患者的口腔中的细菌可能来自其母亲的口腔。(3)患者的心理自我评估：向患者和牙科人员（牙科学生、口腔医学家和牙科医生）提供与牙周状况自我评估标准相关的工具。患者对牙周状况的估计与牙科人员有很大差异。结论：牙周手术后患者和牙科人员对牙龈退缩的评价存在差异。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
