| Abstract |
|
Pit and fissure sealant prevents biofilm accumulation, plays a role in forming a barrier to acidic substance made by the bacteria. The Surface reaction-type pre-reacted glass ionomerI(S-PRG) filler was developed in 1999. S-PRG filler releases fluoride continuously and does not decompose under wet conditions. The aim of this study was to test the microleakage and anticariogenic effect to adjacent enamel of S-PRG filler-containing pit
and fissure sealant. Sound premolars and molars were used in this study. A S-PRG filler-containing pit and fissure sealant, Beautisealant®(Shofu, Japan) was used for this experiment, the composite resin sealant Concise®(3M ESPE,USA) was used as control. For the microleakage test, all teeth surface were double coated with finger nail varnish,
with the exception of a 1.0 mm window around the restoration margins. The teeth were immersed in 2% methylene blue solution for 24 hours and then rinsed in tap water. For the anticariogenic effect evaluation, all tooth were immersed in artificial carious solution for 9 days and rinsed with tap water. Each tooth was embedded in orthodontic acrylic rein and subsequently sectioned longitudinally in a bucco-lingual direction with a lowspeed diamond saw. The cut sections were examined using a stereomicroscope.
Differences in microleakage between the two groups were not different significantly. But the S-PRG filler-containing
pit and fissure sealant showed higher anticariogenic effect than that of flowable resin sealant. |
