성견에서 조직유도재생술과 구연산, 테트라싸이크린으로 치근면 처치한 경우 치주조직의 치유에 미치는 영향 = THE EFFECTS OF ROOT TREATMENT WITH CITRIC ACID AND TETRACYCLINE AND GUIDED TISSUE REGENERATION ON THE PERIODONTAL HEALING RESPONSES IN DOGS

다국어 초록 (Multilingual Abstract)

The ultimate goal of periodontal therapy is to fully reconstruct the periodontal attachment apparatus. Commonly used techniques for treatment of infrabony defects include a combination of root planing, curettage and root treatment. To prevent the apical migration of epithelial cells, the technique of guided tissue regeneration is used.
The aim of this study is to compare the effects of root treatment with Citric acid & Tetracycline and Guided tissue regeneration in dogs. Experimental periodontitis was induced by the ligation of orthodontic elastic threads in the upper right and left premolars 3, 4 of five audlt dogs for 6 weeks.
4 types of porcedures were performed as follows;
1) Contol group : Mucoperiosteal flap
2) Experinental Ⅰ : GTR used Gore-tex?? membrane
3) Experinental Ⅱ : Root treatment with citric acid (PH1)
4) Experinental Ⅲ : Root treatment with tetracycline HCl (50mg/ml)
There after, dogs were serially sacrificed at the 1, 2, 4, 5, 8 weeks, and the specimens were prepared, and stained with hematoxylin-eosin stain for the light microscopic evaluation.
The results of this study were as follows;
1. Junctional epithelium reached to the notch through the furcation area in control group at 8 weeks.
2. In the aspects of the inflammatory cell infiltration, control group showed severe aggregation than experimantal group Ⅰ, Ⅱ, Ⅲ through the experimental period.
3. New cementum was observed over the notch from 5 weeks in experimental group Ⅱ
4. In the aspects of the amount of new bone formation, experimental group was better than control group, but there was not significant differences among the experimental group Ⅰ, Ⅱ, Ⅲ
