| 總結: | Twenty humar extracted premolar teeth were randomly divided into 4
groups, group I,
The aim of this was to investigate the effect of application of flowable
composite resin as an intermediate layer toward the microleakage of packable
composite resin restorations with ramped and conventional light curing

for flowable composite resin application, IA which was
performed ramped curing technique and IB which was performed conventional
curing technique, then group II, without flowable composite resin application, IIA
which was performed ramped curing technique and IIB which was performed
conventional curing technique. Specimens were stored in artificial saliva for 24

incubator and centrifuged for 5 minutes at 3000 rpm. Specimens cutted into tow
pieces with separating disc vertically in mesiodistal direction, and dye
penetration was assessed using stereo microscope 250 magnification according to
0-3 scoring point. Data was analyzed using Kruskal Wallis 95% and U-Mann
Whitney tests at <0,05 significance level and 95% confidence level.

The results showed the effect of application of flowable composite resin with
curing techniques (p = 0.016) toward the microleakage of packable composite
resin restorations. The results of microleakage means of group IA (1.40 0.548),
IIA (2.20 + 0.447), IIB (2.40 + 0.584), and IB (2.80 + 0.447).
Conclusions of the study that there were the effect of application of flowable
composite resin as an intermediate layer toward the microleakage of packable
composite resin restorations with ramped and conventional light curing
technique. |
