Sažetak
Objectives: The aim of this study was to determine increase in transillumination of composite posts after etching and treatment in cold H2 plasma. Methods: Initial spectrophotometric measurement was taken for each of 20 FRC Postec composites used (Ivoclar, Schaan, Liechtenstein). Each post was illuminated with LED lamp LUX.V ST. HEX LAMB. DENT-BL. LXHL_LRD5 (455 nm) and light collected with fiber P600-2-VIS_NIR (Ocean Optics) on three places, coronal, middle and apical, each three mm apart. Information was collected with Spectrometer Ocean Optics (HR-2000 CGI-UV-VIS) and processed with computer program OOIBase32 (Ocean Optics). Based on similar values posts were placed in four groups of five. Group 1 was etched with orthophosphoric acid, Group 2 treated in H2 plasma 60 sec, 250W, 40 Pa, Group 3 treated in H2 plasma 30 sec, 250W, 40 Pa and Group 4 was a control group. Results: Values of Group 1 for untreated samples coronally, middle and apically (K, M and A) were 1148±24, 505±21 and 224±10, respectively, and for treated samples K was 1160±32, M was 503±12 and A was 186±27. Values for Group 2 for untreated K was 1361±9, M was 650±20 and A was 303±16. For treated K was 1473±35, M was 776±32 and A was 336±47. In Group 3 for untreated K was 1209±9, M was 550±28 and A was 250±18 while for treated K was 1208±39, M was 560±14 and A was 262±23. Group 4 was a control group where sensitivity of method was determined with several consecutive measurements. Conclusion: Etching of posts in plasma increases transillumination of posts up to 10% which may enable better setting of adhesive cements compared to treatment with ortophosphoric acid.
