Abstract
|
|
|
The purpose of this study was to compare the microleakage pattern of preventive resin restoration using conventional composite resin and allowable composite resin that recently developed. 60 sound premolar teeth were allocated to three groups. Flowable composite resin was used for the experimental groups(GroupⅠ,Ⅱ) and conventional resin for the control group(Group Ⅲ) . After composite fi11ing and sealant application. all teeth were thermocycled and evaluated for microleakage under light microscope. Additionally, a variety of voids formed inside restorations were also evaluated. Data were analyzed statistically using Kruskal-Wallis test and/or Mann-Whitney U-test. The results of the present study were as fo11ows .
1.Microleakage found in all samples was only limited to the interface o( restoration margin and enamel.
2.The flowable composite resin groups (GroupⅠ, Ⅱ) generally showed less micoleakage than control groups
(conventional preventive resin restoration) (p〈0.05)
3.Various types of voids were observed in most specimens. Especially, there was a tendency for more and larger voids to be found in group Ⅰ, Ⅱ than group Ⅲ (p〈0.05).
