Abstract
The objective of this study was to compare dentin shear bond strength (DSBS) of dentin bonding agents
(DBAs) cured with a plasma arc (PAC) light curing unit (LCU) and those cured with a light emitting diode
(LED) LCU. Optical properties were also analyzed for Elipar freelight 2 (3M ESPE); LED LCU, Apollo
95E (DMT Systems); PAC LCU and VIP Junior (Bisco); Halogen LCU. The DBAs used for DSBS test
were Scotchbond Multipurpose (3M ESPE), Singlebond 2 (3M ESPE) and Clearfil SE Bond (Kuraray).
After DSBS testing, fractured specimens were analyzed for failure modes with SEM.
The total irradiance and irradiance between 450 ㎚ and 490 ㎚ of the LCUs were different. LED LCU
showed narrow spectral distribution around its peak at 462 ㎚ whereas PAC and Halogen LCU showed a
broad spectrum. There were no significant differences in mean shear bond strength among different LCUs
(P > 0.05) but were significant differences among different DBAs (P < 0.001).
광물리학적 특성 분석을 위해 Apollo 95E (DMT Systems, Orange, CA; PAC 광중합기), Elipar Freelight 2
(3M ESPE, MN, USA; LED 광중합기) 그리고 VIP Junior (Bisco, Schaumberg, IL, USA; QTH 광중합기), 3종
의 광중합기의 총광강도(Total intensity)와 spectral distribution을 측정하였고 특정 파장에 해당되는 광강도
(Energy density)를 분석하였다. 상아질 전단접착강도의 측정을 위해 Scotchbond Multipurpose (3M ESPE),
Single bond (3M ESPE) 그리고 Clearfil SE bond (Kuraray)가 사용되었다.
Plasma Arc Curing light (Apollo 95E) 광중합기는 여러개의 최대정점을 가지며 넓은 spectral distribution과
2307 ㎽/㎠의 높은 광강도를 나타내었고, VIP Junior 광중합기는 490 ㎚에서 최대정점을 갖는 넓은 spectral distribution을
나타내었고, Elipar Freeelight 2 광중합기는 462 ㎚의 최대정점 주위로 좁은 spectral distribution을 보였
다. Two-Way ANOVA와 Bonferroni’s multiple comparison test를 이용하여 상아질 전단접착강도를 분석한 결과,
PAC 광중합기와 LED 광중합기 간에 유의성 있는 차이를 보이지 않았으며 (P > 0.05), 상아질 접착제와 광중합기의
교호관계에도 유의성이 없었다. 그러나 상아질 접착제는 상호간에 유의성 있는 차이를 보였다 (P < 0.001).
