The purpose of this study was to evaluate the marginal microleakage in Class II with different materials in resin composite restorations cured by using "soft start" and standard polymerization techniques. Two adhesive Class II cavities were prepared in 50 human teeth with enamel in-between. Samples were divided into 5 groups and filled with composite resins, compatible flow resin composites and bonding systems. The ocluso-mesial restorations were cured with standard curing technique, and the ocluso-distal restorations were cured with "soft start" curing technique. After thermocycling, the teeth were immersed in silver nitrate solution and sectioned for leakage evaluation. The results pointed out, after "soft start" and standard curing techniques, that the best marginal behavior in Class II restorations was obtained with Tetric Ceram / Tetric Flow composite resins, then with Filtek Z 250 / Filtek Flow, followed by Admira Admira Flow and Point / Revolution composite materials. The deepes...t dye penetration was found in cavities with Diamond Lite / Diamond Link composite restorations. No statistically significant difference was found in the tested composite resin restorations, whether treated with "soft start" polymerization or with standard polymerization technique, in regard to marginal micro leakage.
Cilj istraživanja bio je provera kvaliteta rubnog zatvaranja kaviteta II klase restaurisanih različitim kompozitnim materijalima posle polimerizacije "soft start" i standardne tehnike svetlosne polimerizacije. Na svakom zubu urađene su po dve adhezivne preparacije II klase, pri čemu su kaviteti bili međusobno odvojeni slojem gleđi. Uzorci zuba su podeljeni u 5 grupa i ispunjeni odgovarajućim kompozitnim materijalima, kompatibilnim tečnim kompozitima i pratećim adhezivnim sistemima. Ispuni II klase na okluzo-mezijalnim površinama polimerizovani su standardnom tehnikom polimerizacije, dok su ispuni II klase na okluzo-distalnim površinama polimerizovani "soft-start" tehnikom svetlosne polimerizacije. Nakon procedure termocikliranja, uzorci su podvrgnuti ispitivanju kvaliteta rubnog zatvaranja metodom linearnog prodora rastvora srebronitrata. Dobijeni rezultati su ukazali da je i posle primene "soft start" i posle primene standardne tehnike polimerizacije najbolje rubno zatvaranje kaviteta... II klase ostvareno primenom Tetric Ceram / Tetric Flow kompozitnih materijala, potom kod Filtek Z 250 / Filtek Flow, Admira /AdmiraFlow i Point 4/Revolution kompozitnih materijala. Najveći prodor bojenog rastvora srebro nitrata zapažen je kod kaviteta restaurisanih Diamond Lite / Diamond Link kombinacijom kompozitnih materijala. Razlike u dobijenim rezultatima u kvalitetu rubnog zatvaranja između testiranih kompozitnih materijala nakon primene "soft start" i standardne tehnike svetlosne polimerizacije nisu bile statistički značajne.
