Abstract

Kad se ustanovilo da je karijesom uništeno zubno tkivo potrebno nadomjestiti, javila se potreba za pronalaskom adekvatnog materijala. Prvi pravi takav materijal bio je amalgam, slitina žive s jednim ili više metala. Upravo ta živa bila je predmetom mnogih rasprava u krugovima struke zbog čega su se dogodili i amalgamski ratovi. Uz živu, postoji niz nedostataka - pojava rubne pukotine, siva boja, sekundarni karijes i preventivno proširenje kaviteta. Veliki korak prema poboljšanju karakteristika materijala bila je pojava kompozitnih smola. Svojstvima kao što su bijela boja, mogućnost nijansiranja, poštedna preparacija, zaobljeni rubovi kaviteta, nadmašili su amalgam, ali ne u potpunosti. Nedostatak je relativno visoka cijena. Nakon kompozita došli su staklenoionomerni cementi - dvokomponentni materijal dostupan i u kapsuliranom izdanju za jednostavniju i precizniju upotrebu. Istaknuli su se činjenicom da za rad ne iziskuju suho radno polje, a uz to otpuštaju i ione fluora. Time je SIC postao prvi materijal izbora kad se radi o dubokim kavitetima u blizini pulpe, ali i u sanaciji mliječnih zuba. Zbog lošije boje, slabije mogućnosti poliranja i veće cijene, indikacije za korištenje su se smanjile. Prošle se godine pojavljuje novi dvokomponentni materijal, naziva Cention N. Svrstava se u kompozitne smole. Cention N obuhvatio je prednosti svih dosad korištenih materijala. Bojom zadovoljava estetske standarde današnjice, može se nanositi u jednom sloju, dobro se polira te uz fluoridne otpušta kalcijeve i hidroksilne ione. Cention N djeluje i kao depo-preparat čime održava neutralan pH u ustima unatoč pojavi kariogenih bakterija.

Abstract (english)

When destroyed dental tissue needs to be restored, adequate material is required. The first such material was amalgam, a mixture of mercury and one or several metal alloys. It was the mercury that was a controversial choice among professionals which led to the so-called amalgam wars. Amalgams have a wide range of drawbacks – marginal fractures, grey color, secondary caries, and preventive cavity expansions. A significant step in terms of improving materials were composite fillings. The white color, shade selection, cost-effective preparation, round cavity walls – outweigh the use of amalgam fillings, but not entirely. The price remains its biggest obstacle. After composite resins, glass-ionomer cement was used. The two-component material is also available in capsules for more accurate use, notable for the fact that they do not require a dry working field and because they release fluoride ions. Therefore, glass-ionomer cement became the first choice when treating deep pulp cavities but also when repairing deciduous teeth. Due to poor coloring, lower possibility of polishing and greater costs, the use has dropped. New two-component material Cention N, a composite resin sort, came into use last year. The benefits over the previously used materials are abundant. Its color satisfies the aesthetic standards of today; it can be applied in a single layer; it polishes well, and apart from fluoride, it releases calcium and hydroxyl ions. It also acts as a dental depot, maintaining a neutral pH in the mouth despite the onset of cariogenic bacteria.
