Study of preventive and early treatment for periodontitis and pulaiti s on person of advanced years

本文对老年人牙周炎、牙周炎的预防和早期治疗进行了研究，结果如下：抗微生物牙周治疗可降低冠心病高危人群的c反应蛋白水平。我们评估了支持性周治疗（SPT）对维持周患者的有效性。牙前患者的牙床维持对残牙的保存有一定的帮助。牙齿特定部位的小管数量与年龄变化有一定的关系，但相关性并不精确。4 . Er: yagleleware扩根牙根后根尖周组织反应的组织病理学研究。老年人牙髓复合体的显微观察。牙本质-牙髓复合体的变化与年龄有关。释放氟化物的复合绳和粘结剂使牙本质高度钙化。含无细菌沸石的复合树脂无细胞毒性。菌斑在S-PRG（表面反应型Pre-Reactecl Glass lonomer）树脂上的积累明显受到抑制，在这些表面上观察到薄层状的界面物质。这些结果在老年人的牙科治疗中起着重要的作用。

Study of preventive and early treatment for periodontitis and pulaitis on person of advanced years weve exaimed and the results weve as follows :1.Auti-microbial periodontal treatwent decrease c-reactive protein level in patieuts who aer at high risk for coronany huart disese.2.The usefulness of supportive periodoutal therapy (SPT) weve evaluated on maitenance of peridontal patieuts.SPT on maintenance of preiodontal patients was useful for the conservation of residual teeth.3.There is a relationship between of the tubules at specifie areas of tooth and age grope, but the correlation was not precise.4.Histopathological study on the periapical tissue reaction of tooth canal enlarged using Er : YAGleaser ware examined tested tips could abrade and vaporize pulp tissue, predentin and dentin.5.Microscopie observation of dentiu-pulp complex weve examined in elderiy.The change of Dentin-pulp complex was depended on age.6.A fluoride-releasing composite reins and bonding agents atowed a high calcification to dentin.7.Composite resin including autiacterial zeolite showed no cytotoxicity.8.Plaque accumulation on S-PRG (surface reaction type Pre-Reactecl Glass lonomer)resin was significautly inhibited and thin layer-like interfacs substance observed on these surface.These results plays an important role in dental treateut for a person of advanced years.
