The aim of this study was to identify and quantify the major or detectable monomers released from any of five commercially-available, light-cured pit and fissure sealants with three different light sources : conventional halogen light curing unit, plasma arc light curing unit and LED curing unit. After curing, specimens were immediately immersed in distilled water for different time intervals. The time related release of monomers were analyzed by high performance liquid chromatography(HPLC). Identification and quantitative analysis of monomers were performed by the comparison of the elution time and the absorption peak height of the eluates with those of the authentic sample.

The result of this study can be summarized as follows.

1. Standard solution peaks with retention times of 2.3, 3.2, 5.6, 6.5, 10.4 minutes were identified as BPA, TEGDMA, UDMA, Bis-GMA, Bis-DMA, respectively.

2. None of the chromatograms of the tested sealants displayed peaks with the same retention time as that of the standard solution, except for TEGDMA.

3. The highest release rate of TEGDMA was observed during the 12hr period for all samples and declined thereafter.

4. The elution of TEGDMA from curing with Halogen curing unit for 20 second and LED for 10 second was less than that resulting from curing with Plasma arc for 3 second.

5. TEGDMA was detected at much lower levels in eluates from the Pit & Fissure Sealant¢â than other sealants. The elution of TEGDMA from the Helioseal£¿ F cured with Halogen light curing unit, the Concise¢â cured with Plasma arc curing unit and the Teethmate£¿ F-1 cured with LED curing unit were higher than other sealants.
