역행충전시 수복재와 와동 형태에 따른 변연누출의 정량적 분석
한충경 전남대학교 치과대학 1989 전남치대논문집 Vol.1 No.2
When conventional root canal treatment is failed or contraindicated, retrograde root canal filling following apicoectomy is a valuable procedure, aimed at hermetically sealing the root canal against leakage of irritants from the canal into the periapical tissue. In this in vitro investigation, to analyze apical microleakage electrochemically in teeth with different retrograde filling materiasl and preparation types, single-rooted tooth was cut 2㎜ from the apex and each Class I and Slot preparation was prepared. Experimental groups : Group 1. Amalgam filling with cavity varnish in Class I preparation Group 2. Scotchbond 2+Silux filling in Class I preparation Group 3. Gutta percha filling with ZOE cement in Class I preparation Group 4. Amalgam filling with cavity varnish in Slot preparation Group 5. Scotchbond 2+Silux filling in Slot preparation Each specimens was immersed in 1% solution of KCI, and applied a potential of 9V external power supply. Measurements of the current flow were obtained at 1, 2, 3, 7, 9, 12, 14, 18, 21, 25 and 28 day after immerson. Marginal microleakage wre compared and evaluated. The results were as follows : 1. The group filled with composite resin with dentin bonding agent shows lower apical microleakage value than the group filled with amalgam following varnish application(P<0.01). 2. In the group filled with gutta percha, apical microleakage value was the hightest. 3. There was no significant difference between Class I cavity and Slot type cavity regardless of the used materials.
