Abstract
[한글]

본 연구는 상아질 지각과민 약제로 사용되고 있는 상아질 접착제로서 All-bond 2, Gluma Bonding System, Scotchbond 2, Superbond D-liner의 상아세관 밀봉효과를 관찰하고 0, 140, 420, 840회의 치솔질을 시행하여 각 재료간에 있어 상아세관 밀봉지속효과를 비교,

관찰하기 위하여 시행되었다. 발거된 120개의 치아를 5개의 group으로 나누어 노출된 상아질에 각 재료를 도포하고 group I은 대조군으로서 어떤 상아질 접착제도 도포하지 않았다. 각 시편을 5℃에서 55℃까지 200회의 온도변화를 시킨후 각 group을 다시 4개의group으로 나누어 마모기에서 각각 0, 140, 420, 840회의 치솔질을 시킨후 0.5% mothylene blue에 담궈 24시간동안37℃의 항온기에 보관하였다. 치아를 치아의 장축에 수직이 되도록 절단하여 색소가 침투된 거리를 치수까지의 거리에 대한 비율로 .환산, 비교관찰하여 다음과 같은 결론을 얻었다.

1. 4가지 상아질 접착제 모두 도포직후에는 상아세관 밀봉효과가 우수했다.

2. All-bond 2, Gluma Bonding System, 그리고 Superbond D-liner는 치솔질을 시행후에도 도포직후와 비교해 840회(6주)동안 상아세관 밀봉지속효과를 나타내었다.

3. Scotchbond 2는 420회(3주)의 치솔질 후부터 상아세관 밀봉효과가 유의차있게 감소했다. (P<0.05)

The purpose of this study was to observe the sealing ability and durability of AlI-Bond 2, Gluma Bonding System, Scotchbond 2 and Superbond D-liner which are dentin bonding agents used as desensitizing agents.

The durability of the sealing ability of the materials were compared after 0,140,420, 840 tooth brushing strokes. 120 extracted teeth were divided into 5 groups and the agents were applied to the exposed dentin. No agents was applied on group 1

,the control group. Each specimen went through thermocycling from 5℃to 55℃,200times. Each group was decide into 4 subgroups and artificial tooth brushing strokes were done for 0, 140, 420, 840 times. Finally the specimens were stored in 0.5% methylene blue solution for 24 hours in a incubator set at 37℃. The tooth were sectioned perpendicular to the long axis and the dye penetration ratio to the pulp was measured.

The following results were obtained.

1. All four dentin bonding agents initially showed excellent sealing ability.

2. All-bond 2, Gluma Bonding System and Superbond D-liner showed durability of dentinal tubule sealing effect after 840 strokes(6-week) artificial tooth brushing.

3. Scotchbond 2 showed a significant decrease in sealing ability after 420 strokes(3-week) artificial tooth brushing. ( P<0.05)
