An experimental laboratory study has been conducted to investigate the effect of temporary zinc oxide eugenol cement on the transverse strength of self-cure acrylic resin. Two groups of resin plates 20x9x1 mm in dimensions were incorporated in the study. Each groups consisted of 31 specimens. On the first group was applied a 0.1 mm thickness of temporary zinc oxide eugenol cement on acrylic which is only partially polymerized. The time we establish here was 30 minutes, thus the zinc oxide eugenol cement was applied 30 minutes following the beginning of the mix. After being stored in a incubator with the temperature set at 37°C for 7 days in water, all the specimens were subjected to load by Shimadzu machine with cross head speed of 0.05 inch/min- Results were analyzed with T-test showing that the two groups differed significantly. It was observed that zinc oxide eugenol cement decreases the transverse strength of self-cure acrylic resin significantly By mathematical equation, 0-03 mm increase in thickness in the experimental group might produce the same strength as the control group.

Kontaminasi bakteri pada tumpatan sementara dapat menyebabkan kegagalan perawatan. Tujuan penelitian ini adalah untuk mengetahui perbandingan sealing ability tumpatan sementara berbasis zinc oxide eugenol dan non-eugenol. Dua puluh gigi premolar yang telah diekstraksi ditumpat 4 bahan tumpatan sementara zinc oxide yang berbeda lalu direndam selama 5 hari dalam methylene blue 1% dan diuji penetrasi pewarna dengan skoring menggunakan alat stereomikroskop Nikon SMZ800, Japan (perbesaran 63x). Hasil penelitian menunjukkan sealing ability pada tumpatan sementara zinc oxide non-eugenol lebih baik dibandingkan zinc oxide eugenol. ......Bacteria contamination on temporary filling can cause treatment failure. The aim of this study was to evaluate the sealing ability of zinc oxide eugenol and noneugenol based temporary filling by dye penetration test using scoring. Twenty extracted maxillary premolar were filled with 4 different temporary filling, then immersed in 1% methylene blue solution for 5 days and evaluated under stereomicroscope Nikon SMZ800, Japan (63x). Results showed that sealing ability of zinc oxide non-eugenol based temporary filling was better than temporary filling based of zinc oxide eugenol.
