Abstract
Kompomerni materijali skupina su dentalnih materijala koji kombiniraju neka svojstva stakleno-ionomernih cemenata i kompozitnih materijala. Svrha ove studije bila je vrjednovati stupanj retencije kompomera kao materijala za pečaćenje fisura nakon dvanaest mjeseci. Osamdeset sedam zuba s izraženom fisurnom morfologijom podijeljeno je u tri skupine te su im okluzalne plohe zapečaćene kompomerom (Compoglass-Vivadent) primjenom različitih metoda pripreme okluzalne plohe. Skupina A od 24 zuba zapečaćena je metodom preporučenom od proizvođača. Skupina B sastojala se od 36 zuba koji su jetkani 37% ortofosfornom kiselinom i upotrijebljen je izvorni adhezivni sustav. U skupini C 27 je zuba jetkano 37% ortofosfornom kiselinom i upotrijebljen je adhezivni sustav (Optibond-Kerr). Retencija pečata u skupini A nakon dvanaest mjeseci bila je 87,5%. Pečat je djelomice ili potpuno nedostajao kod tri zuba. U skupini B retencija je bila 86,1%, s potpunim ili djelomičnim gubitkom pečata u pet zuba. Retencija pečata nakon 12 mjeseci u skupini C bila je 77,8%. U šest zuba pečat je djelomično ili potpuno nedostajao. Studentov t-test nije ustanovio statistički znatnu razliku među skupinama i metodama pečaćenja. U 87 zuba koji su bili pečaćeni kompomerom retencija je nakon 12 mjeseci bila 83,9% (pečat intaktan kod 73 zuba) s dvijema novim karijesnim lezijama. Stupanj retencije kompomernog materijala za pečaćenje fisura usporediv je s rezultatima dobivenim uporabom kompozitne smole i može se preporučiti u svakodnevnoj praksi.Compomer materials combine some properties of glass ionomer cements as well as composite materials. The aim of this study was to evaluate the retention rate of compomer, used as a fissure sealing material after a clinical trial of twelve months. Eighty teeth, divided into three groups were sealed with compomer material (Compoglass, Vivadent) after different treatment of the occlusal surfaces. Group A comprised 24 teeth, sealed according to the manufacturer’s recommendations. Group B consisted of 36 teeth, etched with 37% phosphoric acid and original adhesive system applied. In Group C 27 teeth were sealed after etching of occlusal surfaces with 37% phosphoric acid following application of adhesive system (Optibond, Kerr). After twelve months the retention rate in Group A was 87.5%. Sealant was completely or partially missing in 3 teeth. In Group B retention rate was 86.1% with sealant completely or partially missing in 5 teeth while in Group C 77.8% of the teeth were completely sealed and in 6 teeth the sealant was completely or partially missing. Student t-test did not reveal statistically significant difference between the groups and techniques of sealing. Generally, retention rate of 87 teeth sealed with compomer material after 12 months of clinical service was 83.9% (sealant intact in 73 teeth) with no new caries lesions. Results are comparable with results obtained using classic composite sealant materials and can be recommended in everyday practice. However, long-term evaluation is still needed to obtain more reliable data
