Summary: | Introduction. Increasing requirements for durable fillings and marginal
integrity have influenced the development of new materials and restorative
techniques. Contemporary demands for esthetic restorations have encouraged
the development of new composite material ?self-etch flowable composite?. The
aim of this study was to test the marginal seal in small Class V cavities
after restoration with self etch flowable composite material Vertise Flow and
flowable composite Tetric Flow, both polymerised using conventional
light-curing technique. Material and Methods. The study was conducted on 40
extracted human teeth (20 intact, 20 carious). Each group included 10
premolars and 10 molars. In all teeth two cavities class V of diameter 3?2?2
mm were prepared (buccal and lingual surface). On the buccal surface the
cavities were filled with self etch flowable composite Vertise Flow (Kerr
Dental Products), and on the lingual surface with flowable composite Tetric
Flow (Ivoclar Vivadent) using appropriate adhesive system. Polymerisation was
performed using LED lamp (Ivoclar Vivadent). Microleakage was tested with
silver nitrate solution. Using stereoloupe with micrometer scale and six
times magnification dye penetration was measured. Results. Mean dye
penetration in intact molars restored with Vertise Flow was 3.41 ?m, while in
intact molars restored with Tetric Flow it was 4.23 ?m. In intact premolars
restored with Vertise Flow, the average dye penetration was 1.14 ?m and in
intact premolars restored with Tetric Flow it was 3.90 ?m. Dye penetration in
carious molars restored with Vertise Flow and polymerised using conventional
polymerization technique was 3.66 ?m, while using Tetric Flow it was 7.94 ?m.
In carious premolars restored with Vertise Flow dye penetration was 3.97 ?m,
while with Tetric Flow it was 7.12 ?m. The total dye penetration was lower in
intact compared to carious teeth. Greater dye penetration was found in molars
compared to premolars. Conclusion. Vertise Flow showed better quality of bond
with hard dental tissue than Tetric Flow when classical polymerization
technique was used.
